7:12.1.2.7.16.1.1.17.26 :

Exhibit B to Subpart A of Part 1924 - Requirements for Modular/Panelized Housing Units

For the benefit of the Agency this exhibit prescribes evaluation, acceptance, inspection and certification procedures formodular/panelized housing units proposed for use in Agency Rural Housing programs. It applies to proposed development packages provided either under a contract between an Agency borrower and a single contractor or under a conditional commitment. This exhibit also describes the use of background information available through the Department of Housing and Urban Development (HUD) for analysis of manufactured products. This exhibit also applies to the evaluation of manufactured farm service buildings in paragraph XI, below. For the purpose of this exhibit, County Supervisor and County Office also mean District Director and District Office, respectively.

I. Applicable Standards and Manuals.

A. The HUD Handbook 4950.1, Technical Suitability of Products Program Technical and Processing Procedures, must be followed by housing manufacturers to obtain acceptance of their products. Acceptance documents issued by HUD include: Structural Engineering Bulletins (SEB) on a national basis, Area Letters of Acceptance (ALA) which when accepted by all Area HUD Offices in a HUD region will, in essence, become Regional Letters of Acceptance (RLA), Truss Connector Bulletins (TCB): and, Mechanical Engineering Bulletins (MEB). These documents as well as the Use of Material Bulletins (UM) and Materials Release Bulletins (MR) are addendums to the HUD Minimum Property Standards (MPS), Under handbook guidelines, HUD also examines state agency regulations concerning design, construction and labeling of modular/panelized housing units and designates those states having procedures acceptable for use under HUD programs. Modular/panelized housing produced in these states is called Category III and is considered technically suitable for use without further structural analysis.

B. All Agency Offices should maintain a close working relationship with each HUD office in their jurisdiction to assure coordination. Any deviations in structure, materials or design from HUD acceptance documents must comply with one of the other applicable development standards.

II. Modular Housing Units that Require Factory Inspections.

Only those types which cannot be completely inspected on site are required to obtain acceptance from HUD. Those that receive acceptance will be periodically factory inspected by HUD or HUD's designated agency, usually about every 6 months.

III. Panelized Housing Units that Do Not Require Factory Inspections.

A. Housing completely assembled on the building site does not require HUD acceptance. This includes housing that is manufactured but is assembled on the site such as: Precut pieces, log wall houses, trussed roof rafters or floor trusses; open panel walls, and other types that can be completely inspected on site.

B. Housing that is assembled in local materials dealers' yards for moving to local sites and to be purchased by an Agency applicant, will be inspected during construction in the yard by the local Agency County representative. These units must be constructed according to the applicable development standard and not transported out of the local Agency County Office jurisdiction. The inspection must be recorded on Form RD 1924-12, “Inspection Report.”

IV. Manufacturer's Actions Required for Submissions to the Agency are listed in attachment 1 to this exhibit B.

V. State Agency Office Actions when Manufacturing Facilities are in its Jurisdiction. The State Office, upon receipt of manufacturer's submission, must:

A. Determine that the unit structural system has been accepted by HUD as appropriate under HUD Handbook 4950.1 requirements.

B. Review the thermal characteristics and approach of the calculations to determine actions to be taken in compliance with paragraph IV C of exhibit D of this subpart.

C. Review the proposal for compliance with § 1924.5(d)(1) of this subpart.

D. Determine that the prerequisites for consideration of acceptance by the Agency are met. The prerequisites include all of the following:

1. A current acceptance document from HUD (SEB, RLA, ALA), except for Category III housing (modular/panelized housing that does not have to have a Structural Engineering Bulletin as designated by HUD). In Category III states, the state government requirements for manufactured housing must be followed.

2. A current HUD Factory Inspection Report, Form No. 2051m, or in the case of Category III housing, a copy of the inspection report from the state government or accepted third party performing the factory inspection. Each report must be made by HUD or a HUD authorized agency, and must be no older than 6 months.

3. A letter from the manufacturer requesting a review for acceptance. Enclosed with the letter shall be all the information listed in attachment 1 to this exhibit B.

E. Issue acceptance letters to the manufacturer stating the conditions of acceptance in the format of attachment 2 to this exhibit B. The letter shall have an attachment listing all models accepted in the format of attachment 3 to this exhibit B. A copy of the acceptance letter and list of models shall be sent to each County Office in the state and, when requested by the manufacturer, to each other Agency State Office in which the product is to be marketed.

F. After initial review of a submission, maintain a master file of accepted manufacturers and models and review the file twice yearly to determine the currency of the factory inspection reports and HUD or state government acceptance documents.

G. Notify manufacturers of overdue factory inspection reports, for acceptance of documents review and updating, using the format of attachment 4 to this exhibit B. Accompanying the notification will be a temporary acceptance sheet (Attachment 3 to this exhibit B) indicating to the manufacturer that the company models have temporary acceptance for 60 days. If the manufacturer provides evidence that a review is being processed by HUD, a maximum of an additional 90 days may be granted. Otherwise, the acceptance shall terminate on the last extension date and it will be necessary for the manufacturer to resubmit as if for initial acceptance.

H. Distribute a list of added models, deleted models, or notice of deletion of any manufacturer's product to the County Offices and other State Agency Offices as necessary.

I. Issue an initial supply of Manufacturer's and Builder's Certification forms (Attachment 5 to this exhibit B) to each existing and newly accepted manufacturer. Manufacturers are to duplicate this form as necessary in their market areas.

J. Resolve any problems with the manufacturer, as reported by the County Office. Action may include coordination, Agency plant inspections or cancellation of acceptance letters when problems persist.

VI. County Office Actions:

A. When an application is received involving any of the manufacturer's products on the accepted list, the County Office Agency authorized personnel will:

1. Review the drawings and description of materials described in paragraphs A and B of attachment 1 to this exhibit B. The floor plans and elevations must be identifiable with the model listed in the accepted list issued by the State Office.

2. Require the builder/dealer or manufacturer to provide any drawings necessary to adapt the house to the site conditions where the house will be located.

3. Require site plan drawing such as those illustrated in attachments 1 and 2 to exhibit C of this subpart (available in any Agency office).

4. Inspect and identify the model delivered against the manufacturer's certification and the accepted drawings and description of materials before the unit has been set on the foundation.

5. Require the builder/dealer to certify that the work for which the builder/dealer is responsible has been erected in compliance with the applicable development standard. This certification will be completed on a copy of attachment 5 to this exhibit B, and filed in County Office case file.

6. Observe any noncompliance with the applicable development standard or with paragraphs IV and V of this exhibit B. In this respect:

a. Minor noncompliance will be resolved by the manufacturer through the builder/dealer. In cases where there is no builder/dealer, the County Office may resolve such issues with the manufacturer directly.

b. Noncompliance that cannot be resolved at the County Office level will be reported to the State Office.

7. Inspect manufactured housing according to § 1924.8(d) of this subpart.

8. Be aware that the accepted list may include many models from which loan applicants may choose. No changes from accepted model designs are permitted. The model selected by an applicant should be appropriate to the needs of that particular family in accordance with 7 CFR part 3550.

VII. Noncompliance Issues.

A. When minor issues are noted, the County Office will attempt to resolve them as described above. If they cannot be resolved locally, they will be referred to the State Office. When any issues cannot be resolved at State Office level, the National Office Program Support Staff (PSS) will be contacted for guidance.

B. The National Office PSS coordinating with HUD, will take the appropriate actions to resolve the issues reported.

C. Manufacturers and builder/dealers must be aware that if the Agency inspector finds any of the following conditions, the inspector may refuse to accept the construction until corrections have been made:

1. Evidence of noncompliance with any option of the method described in the HUD - SEB, RLA, or ALA.

2. Faulty shop fabrication, including surface defects.

3. Damage to shop fabricated items or materials due to transportation, improper storage, handling or assembly operation.

4. Unsatisfactory field or site workmanship.

VIII. Actions by Other State Offices. When a State Office receives a copy of the accepted list from the State Office in which a manufacturing plant is located, it will:

A. Maintain a file, by manufacturer, of each accepted list of models.

B. Provide copies of the accepted list of models to each County Office in the State.

C. Request a copy of the drawings, description of materials, and thermal calculations to determine compliance with the thermal requirements for the county in which the house is to be located according to exhibit D of this subpart.

D. Check to see that County Offices within the state will act as prescribed in paragraph VI of this exhibit B.

E. When two or more State Offices have different interpretations of the acceptability of a particular model, there must be an agreement between the states so that they will have the same requirements. If the states cannot agree, the National Office PSS will be consulted for guidance.

IX. Subsequent Review.

The Agency will make periodic reviews of houses, both site-built and houses manufactured offsite, to determine acceptability of the finished product. If, in the judgment of the Agency, the product has failed to perform satisfactorily, acceptance may be withdrawn. The State Director will notify the manufacturer and/or the builder/dealer of the reasons for the withdrawal no later than the time of withdrawal. Negotiations for corrections will be carried out by the County Office with the assistance of the State Office or National Office, as necessary.

X. Materials and Products Acceptance - Material Release Bulletins, Use of Materials Bulletins, Manufacturer's Instructions.

A. The Materials Release (MR) and Use of Materials Bulletins (UM) provide for the national acceptance of specific nonstandard materials and products not covered in the current HUD MPS.

B. When contractors or builders intend to use products or materials not listed as approved in the MPS, the Agency personnel reviewing or concerned with the approval of construction in which the product is to be used, will require the contractor or builder to furnish a Materials Release Bulletin or Use of Materials Bulletin on the materials or products. If the product has been accepted, the supplier should be able to obtain the bulletin for the contractor or builder from the manufacturer. These bulletins describe the products or materials limitations to use, method of installing or applying, approved type of fasteners, if used, etc. and will provide the contractor with instructions as to proper installation or application.

C. When Agency personnel are unfamiliar with any materials or products which have been accepted in the MPS, they will request the contractor or builder to furnish the manufacturer's instructions to assure that the materials or products are properly installed or applied. Any questions on any product that cannot be resolved in the County Office should be referred to the State Office. When the question cannot be resolved at the State Office level, the National Office PSS should be consulted for guidance.

XI. Manufactured Farm Service Buildings.

A. When a loan application is received that involves a manufactured building or special equipment that cannot be completely inspected on the site, the local State Land Grant University recommendations should be requested.

B. When the County Office questions the advisability of making a loan on a manufactured building, the State Office should also be consulted.

Exhibit D to Subpart A of Part 1924 - Thermal Performance Construction Standards

7:12.1.2.7.16.1.1.17.28 :

Exhibit D to Subpart A of Part 1924 - Thermal Performance Construction Standards I. Purpose

This exhibit prescribes thermal performance construction standards to be used in all housing loan and grant programs. These requirements shall supersede the thermal performance requirements in any of the development standards in § 1924.4(h) of this subpart.

II. Policy

All loan or grant applications involving new construction (except for new Single Family Housing (SFH)) and all applications for conditional commitments (except for new SFH) shall have drawings and specifications prepared to comply with paragraphs IV A or C and IV D of this exhibit. All new SFH construction shall have drawing and specifications prepared to comply with paragraph IV F of this exhibit.

III. Definitions

A. British thermal unit (Btu) means the quantity of heat required to raise the temperature of one pound (.4535 Kg.) of water by one degree Fahrenheit (F). For example, one Btu is the amount of heat needed to raise the temperature of one pound of water from 59 degrees F to 60 degrees F.

B. Glazing is the material set into a sash or door when used as a natural light source and/or for occupant's views of the outdoors.

C. “R” value, thermal resistence, is a unit of measure of the ability to resist heat flow. The higher the R value, the higher the insulating ability.

D. “U” value is the overall coefficient of heat transmission and is the combined thermal value of all the materials in a building section. U is the reciprocal of R. Thus U = 1/R or R = 1/U or 1/C where C is the thermal conductance and is the unit of measure of the rate of heat flow for the actual thickness of a material one square foot in area at a temperature of one degree Fahrenheit. The lower the U value, the higher the insulating ability.

E. Winter degree-day is a unit based on temperature difference and time. For any one day, when the mean temperature is less than 65 degrees F (18.3 degrees Celsius), there are as many degree-days as the number of degrees difference between the mean temperature for the day and 65 degrees F. The daily mean temperature is computed as half the total of the daily maximum and daily minimum temperatures.

F. CABO Model Energy Code, 1992 Edition (MEC-92) - This code sets forth the minimum energy/thermal requirements for the design of new buildings and structures or portions thereof and additions to existing buildings. The MEC is maintained by the Council of American Building Officials (CABO).

IV. Minimum Requirements

A. All multifamily dwellings to be constructed with Agency loan and/or grant funds and all repair, remodeling, or renovation work performed on single family and multifamily dwellings with Agency loan and/or grant funds shall be in conformance with the following, except as provided in paragraphs IV C 3 and IV D of this exhibit:

New Construction - Maximum U Values for Ceiling, Wall And Floor Section of Various Construction

Winter degree days ¹	Ceilings ²	Walls	Floors ³	Glazing ⁴	Doors ⁵
1000 or less	0.05	0.08	0.08	1.13
1001 to 2500	.04	.07	.07	.69
2501 to 4500	.03	.05	.05	.69	Storm door if hollow core door or if over 25% glass.
4501 to 6000	.03	.05	.05	.47	Storm Door.
6001 or more	.026	.05	.05	.47	Storm Door.

Note. U values are not adjusted for framing. Values calculated for components may be rounded. For example, a total R Value of 18.88 converts to a U value of .0529 rounded to .05.

¹ Winter degree-days may be obtained from the ASHRAE Handbook; the “NAHB Insulation Manual for Homes/Apartments”; local utilities; and the National Climatic Center, Federal Building, Asheville, NC. Manuals are available from NAHB RF, Rockville, MD 20850, or NMWIA, 382 Springfield Avenue, Summit, NJ 07901. Other sources of degree day data may be used if available from a recognized authority.

² Insulation must be continuous (i.e. no gaps) above all ceiling joists. In pitched roof construction, compression of insulation at the outside building walls is permitted to allow a 1″ ventilation space under the roof sheathing. For any loose fill insulation, a baffle must be provided. Raised trusses are not required.

³ For floors of heated spaces over unheated basements, unheated garages or unheated crawl spaces, the U value of floor section shall not exceed the value shown. A basement, crawl space, or garage shall be considered unheated unless it is provided with a positive heat supply to maintain a minimum temperature of 50 degrees F. Positive heat supply is defined by ASHRAE as “heat supplied to a space by design or by heat losses occurring from energy-consuming systems or components associated with that space.”

Where the walls of an unheated basement or crawl space are insulated in lieu of floor insulation, the total heat loss attributed to the floor from the heated area shall not exceed the heat loss calculated for floors with required insulation.

Insulation may be omitted from floors over heated basement areas or heated crawl spaces if foundation walls are insulated. The U value of foundation wall sections shall not exceed the value shown. This requirement shall include all foundation wall area, including header joist (band joist), to a point 50 percent of the distance from a finish grade to the basement floor level. Equivalent Uo configurations are acceptable.

Maximum U Values of the Foundation Wall Sections of Heated Basement Not Containing Habitable Living Area or Heated Crawl Space

4501 or more	0.10	.69

* Glazing in heated basement shall be limited to 5 percent of floor area unless alternative Uo combination is documented.

⁴ Sliding glass doors are considered as glazing. The glazing value is for glass only. Glazing shall be limited to 15 percent of the gross area of all exterior walls enclosing heated space, except when demonstrated that the winter daily solar heat gain exceeds the heat loss and the glass area is properly screened from summer solar heat gain.

⁵ 1 3/4 inch metal-faced door systems with rigid insulation core and durable weatherstripping providing a “U” value equivalent to a wood door with storm door and an infiltration rate no greater than .50 cfm per foot of crack length tested according to ASTM E-283 at 1.567 psf of air pressure, may be substituted for a conventional door and storm door. All doors shall be weatherstripped. Any glazed areas must be double-glazed.

Exhibit J to Subpart A of Part 1924 - Manufactured Home Sites, Rental Projects and Subdivisions: Development, Installation and Set-Up Part A - Introduction Part B - Construction and Land Development Part C - Drawings, Specifications, Contract Documents and Other Documentation Part D - Inspection of Development Work Part A - Introduction

I. Purpose and Scope. This exhibit describes and identifies acceptable site development, installation and set-up practices and concepts for manufactured homes. It is intended for Agency field personnel, builders, developers, sponsors, and others participating in Agency housing programs.

This exhibit applies to all manufactured homes (except those referenced in exhibit B of this subpart) on scattered sites or in rental projects and subdivisions and covers the requirements for design and construction of manufactured home communities. The Agency may approve alternatives or substitutes if it finds the proposed design satisfactory for the proposed use, and if the materials, installation, device, arrangement, or method of work is at least equivalent to that prescribed in this exhibit considering quality, strength, effectiveness, durability, safety and protection of life and health.

The Agency will require satisfactory evidence to be submitted to substantiate claims made regarding the use of any proposed alternative.

II. Background. The Agency has authority to make (1) section 502 Rural Housing (RH) loans with respect to manufactured homes and lots, and (2) section 515 Rural Rental Housing (RRH) loans with respect to manufactured home rental projects.

The manufactured home must be constructed in conformance with the Federal Manufactured Home Construction and Safety Standard (FMHCSS) and be permanently attached to a site-built permanent foundation which meets or exceeds the Minimum Property Standards (MPS) for One- and Two-Family Dwellings or Model Building Codes acceptable to the Agency. The manufactured home must be permanently attached to that foundation by anchoring devices adequate to resist all loads identified in the MPS. This includes resistance to ground movements, seismic shaking, potential shearing, overturning and uplift loads caused by wind. Note that anchoring straps or cables affixed to ground anchors other than footings will not meet these requirements.

7 CFR part 1970 applies on scattered sites, in subdivisions and rental projects with regard to the development, installation and set-up of manufactured homes. To determine the level of environmental analysis required for a particular application, each manufactured home or lot involved will be considered as equivalent to one housing unit or lot. Because the development, installation and set-up of manufactured home communities, including scattered sites, rental projects, and subdivisions, differ in some requirements from conventional site and subdivision development, two of the purposes of this exhibit are to:

A. Encourage economical and orderly development of such communities and nearby areas, and

B. Promote the safety and health of residents of such communities.

Therefore, this exhibit identifies those required standards and regulations and suggested guidelines for eliminating and preventing health and safety hazards and promoting the economical and orderly development and utilization of land for planning and development of manufactured home communities. The exhibit also provides the requirements for meeting the following:

A. Resistance to Wind. Foundations and anchorages shall be designed to resist wind forces specified in American National Standards Institute (ANSI) A-58.1-1982 for the geographic area in which the manufactured home will be sited;

B. Proper Installation. The manufacturer's installation instructions provided with each manufactured home shall contain instructions for at least one site-built foundation with interior and/or perimeter supports. Agency field office personnel shall review to determine its adequacy as security for an Agency loan only, the foundation design concept for compliance with this exhibit, the Agency/MPS and any Model Building Code acceptable to the Agency in that particular geographic area; and

C. Proper Foundation Design. Manufactured homes shall be installed on a foundation system which is designed and constructed to sustain, within allowable stress and settlement limitations, all applicable loads. Any foundation and anchorage system or method of construction to be used should be analyzed in accordance with well-established principles of mechanics and structural engineering.

III. Definitions. For the purpose of this exhibit the following definitions apply:

Accessory Building or Structure.

A subordinate building or structure which is an addition to or supplements the facilities provided by a manufactured home.

Anchoring Systems. An approved system for securing the manufactured home to the ground or foundation system that will, when properly designed and installed, resist overturning and lateral movement of the home from wind forces.

Contiguous. Sharing a boundary, adjoining or adjacent. A lot or subdivision is considered to be contiguous to other lots or subdivisions if it is adjoining, touching or adjacent.

Federal manufactured Home Construction and Safety Standards (FMHCSS). A 1976 federal standard, commonly known as the HUD Standard, for the construction, design and performance of a manufactured home which meets the needs of the public including the need for quality, durability and safety. Units conforming to the FMHCSS are certified by an affixed label that reads as follows:

AS EVIDENCED BY THIS LABEL NO. ____ THE MANUFACTURER CERTIFIES TO THE BEST OF THE MANUFACTURER'S KNOWLEDGE AND BELIEF THAT THIS MANUFACTURED HOME HAS BEEN INSPECTED IN ACCORDANCE WITH THE REQUIREMENTS OF THE DEPARTMENT OF HOUSING AND URBAN DEVELOPMENT AND IS CONSTRUCTED IN CONFORMANCE WITH THE FEDERAL MANUFACTURED HOME CONSTRUCTION AND SAFETY STANDARDS IN EFFECT ON THE DATE OF MANUFACTURE. SEE DATA PLATE.

Manufactured Home. A structure which is built to the Federal Manufactured Home Construction and Safety Standards and Agency's thermal requirements. It is transportable in one or more sections, which in the traveling mode is ten body feet or more in width, and when erected on site is four hundred or more square feet, and which is built on a permanent foundation when connected to the required utilities. It is designed and constructed for permanent occupancy by a single family and contains permanent eating, cooking, sleeping and sanitary facilities. The plumbing, heating, and electrical systems are contained in the structure.

Manufactured Home Community. A parcel or contiguous parcels of land which contains two or more manufactured home sites available to the general public for occupancy. Sites and units may be for rent, or sites may be sold for residential occupancy (as in a subdivision).

Manufactured Home Rental Project. A parcel or multiple parcels of land which have been so designated and improved to contain manufactured homes with sites available for rent.

Manufactured Home Site. A designated parcel of land in a manufactured home rental project, subdivision or scattered site designed for the accommodation of a unit and its accessory structures for the exclusive use of the occupants.

Manufactured Home Subdivisions. Five or more contiguous (developed or undeveloped) lots, or building sites that meet the requirements of subpart C of part 1924 of this chapter.

Permanent Perimeter Enclosure. A permanent perimeter structural system completely enclosing the space between the floor joist of the manufactured home and the ground. If separate from the foundation system, the permanent perimeter enclosure shall be secured to the perimeter of the manufactured home, properly ventilated and accessible and constructed of materials that conform to the Agency adopted MPS requirements for foundations.

Pier Support System. Consists of footings, piers, caps, leveling spacers, or approved prefabricated load bearing devices.

Related Facilities. Any nonresidential structure or building used for rental housing related purposes.

Site-Built Permanent Foundation System. A foundation system (consisting of a combination of footings, piers, caps and shims and anchoring devices or required structural connections) which is designed and constructed to support the unit and sustain, within allowable stress and settlement limitations, all applicable loads specified in ANSI A58.1-1982. All loads shall be transferred from the manufactured home to the earth at a depth below the established frost line without exceeding the safe bearing capacity of the supporting soil.

Set-Up. The work performed and operations involved in the placement of a manufactured home on a foundation system, to include installation of accessories or appurtenances and anchoring devices, and when local regulations permit, connection of utilities, but excluding preparation of the site.

IV. Compliance with Local Regulations. These requirements do not replace site development standards established by local law, ordinances, or regulations. Whenever such local standards contain more stringent provisions than any of the site development, installation and set-up minimums of the Agency, the more stringent standards shall govern.

V. Applicable Standards, Regulations and Manuals. A. Manufactured housing to be financed by the Agency must comply with the following standards:

1. Federal Manufactured Home Construction and Safety Standards, 24 CFR part 3280, mandated by Congress under title VI of the Federal Housing and Community Development Act of 1974, except for § 3280.506, “Heat Loss,” of subpart F, “Thermal Protection,” to part 3280.

2. Foundation requirements of the Minimum Property Standards as adopted by the Agency or a Model Building Code acceptable to the Agency.

3. [Reserved]

4. Uniform Federal Accessibility Standard (UFAS).

5. ANSI A58.1-1982, Minimum Design Loads for Buildings and Other Structures.

B. Manufactured housing to be financed by the Agency shall comply with all applicable Agency regulations, including but not limited to the following:

1. Subpart C of part 1924 of this chapter, “Planning and Performing Development Work.”

2. Subpart A of part 1924, exhibit D, “Thermal Performance Construction Standards.”

3. 7 CFR part 1970.

5. Subpart E of part 1944, “Rural Rental Housing Loan Policies, Procedures, and Authorizations.”

The requirements of the above references have not been repeated in this exhibit. Those requirements contained above are either mandatory or minimums and every effort should be made by the applicant, builder-developer or dealer-contractor to utilize higher standards, when appropriate.

Part B - Construction and Land Development

I. General Acceptability Criteria. The following criteria apply to development on scattered sites, in subdivisions and in rental project communities.

A. A manufactured home development including a site, rental project or subdivision shall be located on property designated for that use, where designations exist, by the local jurisdiction.

B. Conditions of soil, ground water level, drainage, flooding and topography shall not create hazards to the property and health or safety of the residents.

C. The finished grade elevation beneath the manufactured home or the first floor elevation of the habitable space, whichever is lower, must be above the 100-year flood elevation. This requirement applies wherever manufactured homes may be installed, not just in locations designated by the National Flood Insurance Program as areas of special flood hazards. The use of fill to accomplish this is a last resort. As is stated in EO 11988 and 7 CFR part 1970, it is the Agency's policy not to approve or fund any proposal in a 100-year floodplain area unless there is no practicable alternative to such a floodplain location.

D. Essential services such as employment centers, shopping, schools, recreation areas, police and fire protection, and garbage and trash removal shall be convenient to the development and any site, community, or subdivision must comply with the environmental review requirements in accordance with 7 CFR part 1970.

E. Manufactured home sites, rental projects and subdivisions shall not be subject to any adverse influences of adjacent land uses. An adverse influence is considered as one that is out of the acceptable level or range of a recognizable standard or where no standard exists is considered a nuisance irrespective of a site being zoned for manufactured home use. Health, safety and aesthetic consequences of location shall be carefully assessed by inspection of the site prior to selection of development. Undesirable land uses sush as deteriorated residential or commercial areas and noxious industrial properties shall be avoided to ensure compatibility. Other undesirable elements such as heavily traveled highways, airport runways, railroad, or fire hazards and other areas subject to recognizably intolerable noise levels shall be avoided.

F. The requirements for streets shall be those found in subpart C of part 1924 of this chapter.

G. The site design and development shall be in accordance with sound engineering and architectural practices and shall provide for all utilities in a manner which allows adequate, economic, safe, energy efficient and dependable systems with sufficient easements for their required installation and maintenance.

H. Utilities for each manufactured home site, rental housing project or subdivision shall be designed and installed in accordance with subpart C of part 1924 of this chapter; and the State health authority having jurisdiction, and all local laws and regulations requiring approval prior to construction.

I. Exhibit C, section V of this subpart shall be complied with by the applicant, dealer-contractor or builder-developer for manufactured home projects with individual water supply and sewage disposal systems. This exhibit shall be used by the Agency County Supervisors, District Directors, and State Directors in reviewing submissions.

J. During the planning, design, and construction of the foundation system and/or perimeter enclosure, provisions shall be made for the installation and connection of on-site water, gas, electrical and sewer systems, which are necessary for the normal operation of the manufactured home. Water and sewer system hookups shall be adequately protected from freezing.

II. Development on Scattered Sites and in Subdivisions. - A. General. Scattered sites and subdivision developments will be planned and constructed in accordance with specific requirements of this subpart, subpart C of part 1924, and 7 CFR part 1970, and the applicable Agency/MPS or Model Building Codes acceptable to the Agency.

3. Have had the towing hitch or running gear, which includes tongues, axles, brakes, wheels, lights and other parts of the chassis that operate only during transportation removed;

4. Have any crawl space beneath the manufactured home properly ventilated and enclosed by a continuous permanent perimeter enclosure. If it is not the supporting foundation, designed to resist all forces to which it may be subject without transmitting to the building superstructure movements or any effects caused by frost heave, soil settlement (consolidation), or shrinking or swelling of expansive soils; and be constructed of materials that conform to Agency adopted MPS requirements for foundations;

5. Have the manufactured home insulated to meet the energy conserving requirements contained in exhibit D of this subpart;

6. Have a manufactured home site, site improvements, and all other features of the mortgaged property not addressed by the Federal Manufactured Home Construction and Safety Standards, meet or exceed applicable requirements of this subpart and subpart C of part 1924 of this chapter, the Agency adopted MPS except paragraph 31-2.2 or a Model Building Code acceptable to the Agency;

7. Have had the manufactured unit itself braced and stiffened where necessary before it leaves the factory to eliminate racking and potential damage during transportation; and

8. Be eligible for financing in accordance with the requirements of either section 502, or section 515 of the Agency's Housing Program, for which purpose the beginning of construction will be the commencement of on-site work even though the manufactured home itself may have been produced and temporarily stored prior to the date of application for financing.

B. Site Planning and Development. The site planning and development of manufactured home scattered sites and subdivisions shall also comply with the following:

1. Arrangement of Structures and Facilities. The site, including the manufactured home, accessory structures, and all site improvements shall be harmoniously and efficiently organized in relation to topography, the shape of the plot, and the shape, size and position of the unit.

IV. Rental Housing Projects. Subpart C of part 1924 of this chapter will be used in preparing and providing supporting documents.

V. Specifications. A. Form RD 424-2, “Description of Materials,” or other acceptable and comparable descriptions of all materials used for site development, foundation installation and the permanent perimeter enclosure shall be submitted with the drawings by the applicant.

B. The material identification information shall be in sufficient detail to fully describe the material, size and grade. Where necessary, additional sheets shall be attached as well as manufacturer's specification sheets for equipment and/or special materials.

Part D - Inspection of Development Work

I. General. The following policies will govern the inspection of all manufactured housing development work. This includes scattered sites, subdivisions, rental housing projects and all accessory structures and related facilities unless otherwise indicated.

II. Inspections. A. The responsibility for frequency and propose of inspections shall be in accordance with § 1924.9(b) (1), (2) and (3) of this subpart. The inspection requirements of § 1924.13 apply to the planning and conduct of construction work on all 515 housing developments that are more extensive in scope and more complex in nature than those involving an individual manufactured housing unit. The Stage 2 inspection customary for site-built housing when the building is enclosed is not required for manufactured homes.

The Stage 2 inspection for manufactured homes will be made within two working days after erection or placement on the foundation to determine compliance with accepted installation drawings and specifications for installation and set-up and to verify that the correct unit is on the site.

Stages 2 and 3 inspections for manufactured homes may be combined when authorized by the State Director.

B. The borrower will join the County Supervisor or the District Director in making periodic inspections as often as possible and always for the final inspection.

C. The borrower should be encouraged to make enough periodic visits to the site to be familiar with the progress and performance of the work in order to protect the borrower's interest. If the borrower observes or otherwise becomes aware of any fault or defect in the work or nonconformance with the contract documents, the borrower should give prompt written notice thereof to the dealer-contractor and a copy of the notice to the appropriate County Supervisor or District Director.

D. During inspection, it will generally be infeasible to determine whether a manufactured unit erected on a site was properly braced and stiffened during transportation. Inspectors should examine these units to determine that there is no obvious damage or loosening of fastenings that may have occurred during transportation. The dealer-contractor must warrant these units against such damage, which should protect the Agency's interest.

III. Warranty Plan Coverage. The warranty requirements for all development work shall be in accordance with § 1924.9(d) of this subpart and 7 CFR part 3550, subpart B.

[51 FR 41603, Nov. 18, 1986, as amended at 52 FR 19283, May 22, 1987; 53 FR 2156, Jan. 26, 1988; 67 FR 78327, Dec. 24, 2002; 81 FR 11029, Mar. 2, 2016]

Exhibit L to Subpart A of Part 1924 - Insured 10-Year Home Warranty Plan Requirements

7:12.1.2.7.16.1.1.17.36 :

Exhibit L to Subpart A of Part 1924 - Insured 10-Year Home Warranty Plan Requirements I. Purpose

In recent years, numerous third-party home warranty plans have been developed offering new homeowners varying degrees of protection against builder default and/or major structural defects in their homes. This exhibit establishes the criteria and procedures by which a warranty plan is found acceptable for new construction of single family homes financed by the Agency. An acceptable warranty plan will:

A. Assure that the Agency borrowers receive adequate warranty coverage,

B. In certain circumstances, eliminate the requirement for the Agency personnel to make the first two construction inspections, and

C. Permit a loan up to the market value of the security (less the unpaid principal balance and past due interest of any other liens against the security), even though the Agency personnel may not have performed period inspections during construction.

II. Types of Warranty Companies

A. An insured warranty company is underwritten by an insurance carrier, licensed to operate as an insurer by the states where the warranty company plans to operate, and has an acceptable rating from a nationally recognized rating company such as A.M. Best Company.

B. A risk retention group is an insurer which is licensed in one state and is authorized, under the Products Liability Risk Retention Act of 1981, to issue its policies in all states. This authority is not challenged by the Agency; however, there remains some question as to the legal propriety of a 10-year insured warranty insurer to be a risk-retention group. If at some future time any state insurance commission or regulatory agency challenges the legal authority of such group, the Agency will reconsider its acceptance of the group.

C. Individual state warranty plans, such as that offered by the State of New Jersey, are backed by the full faith and credit of the state government.

III. Plan Requirements

To be considered acceptable, a warranty plan must include the following features:

A. The entire cost (fee, premium, etc.) of the coverage is prepaid and coverage automatically transfers to subsequent owners without additional cost.

B. The coverage is not cancellable by the warrantor (builder), warranty company or insurer.

C. The coverage age includes at least the following:

(1) For one year from the effective date, any defects caused by faulty workmanship of defective materials.

(2) During the second year after the effective date, the warranty continues to cover the wiring, piping and duct work of the electrical, plumbing, heating and cooling systems, plus the items in (3).

(3) During the third through the tenth years, the warranty continues to cover major structural defects. A major structural defect is actual damage to the load-bearing portion of the home including damage due to subsidence, expansion or lateral movement of the soil (excluding movement caused by flood or earthquake) which affects its load-bearing function and which vitally effects or is imminently likely to affect use of the home for residential purposes.

D. A system is provided for complaint (claims) handling which includes a conciliation and, if necessary to resolve matters in dispute, arbitration arranged by the American Arbitration Association or similar organization.

E. A construction inspection plan is required if the Agency is to eliminate the first two Agency inspections or permit a full market value loan when Agency inspections are not conducted.

IV. Information for Review

A. Companies submitting warranty plans for a determination of acceptability must support requests with the following information.

(1) Evidence that the insured warranty company has met the applicable state licensing and/or regulatory requirements in the state in which the company plans to operate.

(2) Evidence that the insurance carrier underwriting the warranty plan is licensed to operate as an insurer in the states in which the company plans to operate and has an acceptable rating from a nationally recognized company such as A.M. Best Company.

(3) State warrenty plan agencies will provide evidence that the plan is backed by the full faith and credit of the state.

(4) A full description of the warranty plan including information on the fees, builder and home registration procedures, required construction standards, construction inspection procedures, coverage provided and claims procedures.

(5) A sample copy of the warranty information and/or policy which is provided to the homeowner.

(6) Suggested means by which Agency field offices can readily assure that the builder is a member in good standing prior to loan approval and that a warrant will be issued upon the completion of construction prior to the final release of funds.

B. Submission and Acceptance:

(1) Insured warranty companies, except those operating as risk retention groups, and state warranty plan agencies will submit their requests and supporting information to the Agency State Director in the state in which they plan to operate. State Directors will determine the acceptability of insured warranty plans and state warranty plans in their jurisdictions, notify the company or agency of the decision in writing and notify field offices by issuance of a State Supplement including the names and addresses of acceptable warranty companies and any other pertinent information.

(2) Warranty companies claiming authority as risk retention groups will submit their requests and supporting information including certification that it has complied with all requirements of the Products Liability Risk Retention Act of 1981 (Pub. L. 97-45) and information indicating the state in which it is licensed, information to the Agency National Office, Single Family Housing Processing Division. The National Office will determine the acceptability of the warranty of a risk retention group, notify the company of the decision in writing and notify field offices by issuance of an attachment to this exhibit.

V. Warranty Performance

A. County Supervisors will report inadequate warranty performance through their District Director to the State Director. State Directors will review the situation, assist in resolving any problems and, if necessary, initiate action under subpart F of part 1942 of this chapter. State Directors will inform, by memorandum, the Director, Single Family Housing Processing Division, National Office, of any problems with warranty performance and if any debarment action is initiated.

B. State Directors will annually monitor each warranty company and/or its insurer to assure continued compliance with state licensing and/or regulatory requirements.

Attachment 1 - Acceptable Warranty Companies

The warranty companies listed below claim authority to act as a risk retention group under the Products Liability Risk Retention Act of 1981 and as such, to operate in all States to provide 10-year home warranties. This authority remains subject to future challenges by any State insurance commissioner or regulatory agency; however, until such challenge is made, the Agency accepts their warranty.

Exhibit B to Subpart C of Part 1924 - Site Development Design Requirements

7:12.1.2.7.16.3.1.17.38 :

Exhibit B to Subpart C of Part 1924 - Site Development Design Requirements

This exhibit prescribes site development requirements to be used in developing residential sites in all housing programs. These requirements cover only those areas which involve health and safety concerns. They are not intended to cover all aspects of site development. Applicants and developers are expected to follow local practice, as a minimum, in all areas of site development not addressed in this exhibit. When State, local, or other requirements are applicable in addition to FmHA or its successor agency under Public Law 103-354's requirements, the most stringent requirement shall apply.

Proper integration of the natural features of a site with the manmade improvements is one of the most critical aspects of residential development. Poor site planning in large scale subdivisions, rental projects and individual sites, has resulted in a loss of valuable private and public natural resources and caused economic burdens and conditions unsuitable for healthy and pleasant living. Proper site design can preserve desirable natural features of the site, minimize expenses for streets and utilities, and provide a safe and pleasant living environment.

⁴ The minimum is 2.0% if the annual precipitation is more than 50 inches.

IV. Drainage

A. General - 1. Collection and Disposal. Surface and subsurface drainage systems shall be provided, as appropriate, for collection and disposal of storm drainage and subsurface water. These systems shall provide for the safety and convenience of occupants. They shall protect dwellings, other improvements and useable lot areas from water damage, flooding, and erosion.

2. Concentrated Flow. Where storm drainage flow is concentrated, permanently maintained facilities shall be provided to prevent significant erosion and other damage or flooding on site or on adjacent properties.

B. Drainage Design and Flood Hazard Exposure - 1. Storm Frequency. Drainage facilities shall be designed for a 10 year storm frequency of 24-hour duration. Full potential development of all contributing areas shall be used as a basis for this determination.

2. Street Drainage. Streets shall be useable during runoff equivalent to a 10-year return frequency. Where drainage outfall is inadequate to prevent runoff equivalent to a 10-year return frequency from ponding over 6 inches deep, streets shall be made passable for local commonly used emergency vehicles during runoff equivalent to a 25-year return frequency except where an alternative access street not subject to such ponding is available.

3. Foundation Drainage. Appropriate crawl space and foundation drainage shall be provided for the removal of subsurface moisture.

C. Primary Storm Sewer - 1. Pipe Size. Pipe size for the primary storm sewer (any storm sewer or inlet lateral located in a street or other public right-of-way) shall have an inside diameter based on design analysis but not less than 15 inches. Where anticipated runoff from the five-year return frequency rainfall will not fill a 15 inch pipe, a primary storm sewer system usually is unnecessary.

2. Minimum Gradient. Minimum gradient shall be selected to provide for self-scouring of the conduit under low-flow conditions and for removal of sediments foreseeable from the drainage area.

3. Easements. Easements for storm sewers shall be a minimum of 10 feet in width.

D. Drainage Swals and Gutters - 1. Design. Paved gutters shall have a minimum grade of 0.5 percent. Paved gutters and unpaved drainage swales shall have adequate depth and width to accommodate the maximum foreseeable runoff without overflow. Swales and gutters shall be seeded, sodded, sprigged or paved as appropriate to minimize potential erosion. Side slopes shall be no steeper than 2:1.

2. Easements. Surface channels shall have an easement which is at least the width of the channel plus 10 feet.

E. Downspouts - 1. Outfall. Where downspouts are provided, they shall either be connected to an available storm sewer, provided with suitable splash blocks, or empty at acceptable locations onto paved areas so that water drains away from buildings. Downspouts shall not connect to sanitary sewers.

2. Piped Drainage. Piped roof drainage from buildings shall be connected to available storm sewers or empty at locations where no erosion or other damage will be caused.

F. Storm Inlets and Catch Basins - 1. Openings. Where inlets are accessible to small children, openings shall have one dimension limited to 6 inch access. Inlet openings in paved areas shall be designed to avoid entrapment or impedence of bicycles, baby carriages, etc.

2. Access. Access for cleaning shall be provided to all inlet boxes and catch basins.

G. Drywells - Drywells for the disposal of water from foundation drains, crawl spaces, and other small quantity sources shall be permissible where the bottom of drywells project into strata of undistributed porous soil at a level where the bottom of the drywell will be above the ground water table at its highest seasonal elevation.

V. Water Supply Systems

A. Individual Water Systems - 1. General. a. In this subpart, an individual water system is a system which serves fewer customers or connections than the lower threshold for community systems stated in the Safe Drinking Water Act.

b. The system for an individual household should be capable of delivering a sustained flow of 5 gpm. A system supplying water to multiple household shall be designed by a Professional Engineer and have sufficient capacity to serve estimated demand. A test of at least 4 hours duration shall be conducted to determine the yield and maximum drawdown for all wells developed as part of an individual water system. This test may be waived by the State Office based on the hydrologic and geologic conditions in the area.

c. Water that requires continual or repetitive treatment to be safe bacterially is not acceptable.

d. After installation, the system should be disinfected in accordance with the recommendations of the health authority. In the absence of a health authority, system cleaning and disinfection should conform with the current EPA Manual of Individual Water Supply Systems.

e. Any method for individual water supply contained herein which is not permitted by the local health authority having jurisdiction shall not be used.

2. Well Location - a. A well located within the foundation walls of a dwelling is not acceptable except in arctic and sub-arctic regions.

b. Water which comes from soil formation which may be polluted or contaminated or is fissured or creviced or which is less than 20 feet below the natural ground surface (subject to the requirements of the local health authority) is not acceptable.

c. Individual water supply systems are not acceptable for individual lots in areas where chemical soil poisoning is practiced if the overburden of soil between the ground surface and the water bearing strata is coarse-grained sand, gravel, or porous rock, or is creviced in a manner which will permit the recharge water to carry the toxicants into the zone of saturation.

d. Table 5 shall be used in establishing the minimum acceptable distances between wells and sources of pollution located on either the same or adjoining lots. These distances may be increased by either the health authority having jurisdiction or the FmHA or its successor agency under Public Law 103-354 State Director.

Table 5 - Distance From Source of Pollution

Source of pollution	Minimum horizontal distance (feet)
Property Line	10
Septic Tank	50
Absorption field	¹100
Seepage pit	¹100
Absorption Bed	¹100
Sewer Lines w/Permanent Watertight Joints	10
Other Sewer Lines	50
Chemically Poisoned Soil	¹100
Dry Well	50
Other	( ²) -

Notes:

¹ The horizontal distance between the sewage absorption system and the well, or the chemically poisoned soil and the well, may be reduced to 50 feet only where the ground surface is effectively separated from the water bearing formation by an extensive, continuous impervious strata of clay, hard-pan, or rock. The well shall be constructed so as to prevent the entrance of surface water and contaminants.

² Other sources of pollution could be fuel oil or gasoline storage tanks, farm yards or chemical storage tanks, etc. The well should be separated from these sources of pollution a distance recommended by the local health authority.

3. Well Construction - a. The well shall be constructed to allow the pump to be easily placed and to function properly.

b. All drilled wells shall be provided with a sound, durable and watertight casing capable of sustaining the loads imposed. The casing shall extend from a point several feet below the water level at drawdown or from an impervious strata above the water level, to 12 inches above either the ground surface or the pump room floor. The casing shall be sealed at the upper opening.

c. Bored wells shall be lined with concrete, vitrified clay, or equivalent materials.

d. The space between the casing or liner and the wall of the well hole shall be sealed with cement grout.

e. The well casing shall not be used to convey water except under positive pressure. A separate drop pipe shall be used for suction line.

f. When sand or silt is encountered in the water-bearing formation, the well shall either be gravel packed, or a removable strainer or screen shall be installed.

g. The surface of the ground above and around the well shall be graded to drain surface water away from the well.

h. Openings in the casing, cap, or concrete cover for the entrance of pipes, pump or manholes, shall be made watertight.

i. If a breather is provided, it shall extend above the highest level to which surface water may rise. The breather shall be watertight, and the open end shall be screened and positioned to prevent entry of dust, insects and foregin objects.

4. Pumps and Equipment - a. Pumps shall be capable of delivering the volume of water required herein under normal operating pressures within the living unit. Well pump capacity shall not exceed the output of the well.

b. Pumps and equipment shall be mounted to be free of objectionable noises, vibrations, flooding, pollution, and freezing.

c. Suction lines shall terminate below maximum drawdown of the water level in the well.

d. Horizontal segments of suction line shall be placed below the frost line in a sealed casing pipe or in at least 4 inches of concrete. The distance from suction line to sources of pollution shall be not less than shown in table 5.

5. Storage Tanks - a. A system for an individual household shall include a pressure tank having a minimum capacity of 42-gallons. However, prepressured tanks and other pressurizing devices are acceptable provided that delivery between pump cycles equals or exceeds that of a 42 gallon tank. Storage capacity on a system for multiple households must be sufficient to meet estimated peak demands.

b. Tanks shall be equipped with a clean-out plug at the lowest point, and if pressurized, a suitable pressure relief valve.

c. When additional storage is necessary because the well yield will not meet the system peak demands, all nonpressurized intermediate tanks shall be designed and installed in a manner that will prevent the pollution or degradation of the water supply.

B. Community Water Systems - 1. Definition. In this subpart, a community water system is a system which meets the definition in the Safe Drinking Water Act.

2. Design. A community water system shall be designed by a qualified, professional engineer licensed in the state in which the water system will be located. Community water systems shall comply with all Federal and State laws.

VI. Wastewater Disposal Systems

Each dwelling shall be provided with a water-carried system adequate to dispose of domestic wastes in a manner which will not create a nuisance, contaminate any existing or prospective water source or water supply, or in any way endanger the public health.

A. Individual Wastewater Disposal Systems - 1. General. a. In this subpart, an individual wastewater disposal system is a sewage disposal system which serves only 1 dwelling unit.

b. When service from an acceptable public or community system is not available or feasible, and ground water and soil conditions are acceptable, an individual system may be used.

c. Each individual wastewater disposal system shall consist of a house sewer, a pretreatment unit (e.g., septic tank, individual package treatment plant), and acceptable absorption system (subsurface absorption field, seepage pit(s), or subsurface absorption bed). The system shall be designed to receive all sanitary sewage (bathrooms, kitchen and laundry) from the dwelling, but not footing or roof drainage. It shall be designed so that gases generated anywhere in the system can easily flow back to the building sewer stack.

2. Percolation Tests - a. Percolation tests are required unless a waiver is granted by the National Office. Waivers may be granted on a statewide or local basis in cases where an onsite evaluation of soils would be performed by a qualified soil technician, soil scientist, or engineer. Requests for waivers must describe the qualifications of the person evaluating the soils and discuss the criteria to be used in designing the absorption system.

b. In uniform soils one percolation test shall be made within each area proposed for an absorption system. If significant soil variations are encountered or expected, additional tests shall be made for each variation.

c. Percolation tests shall be conducted in accordance with good practice. Guidance for performing these tests is included in the EPA design manual, “Onsite Wastewater Treatment and Disposal Systems.”

3. Subsurface Absorption System - a. Where percolation rates, soil characteristics and site conditions are acceptable, an absorption system may be installed in an area which is well drained, has an acceptable slope, and is acceptable for excavation.

b. Soils with percolation rates less than 1 minute per inch may be used if the soil is replaced with a layer of loamy or fine sand at least 2 feet thick. (Refer to the EPA Design Manual, “Onsite Wastewater Treatment and Disposal System”.)

c. Soils with percolation rates greater than 60 minutes per inch are not acceptable for subsurface wastewater disposal systems.

B. Community Wastewater Disposal Systems - 1. Definition. In this subpart, a community wastewater disposal system is any wastewater disposal system which serves more than 1 dwelling unit.

2. Design. A community wastewater disposal system shall be designed by a qualified, professional engineer licensed in the state in which the system will be located.
