The city recognizes that "manufactured homes" (also known as mobile homes or factory-built homes) are constructed to standards established by the U.S. Department of Housing and Urban Development (HUD Code), and not necessarily to the standards contained in the Uniform Building Code (UBC) which applies to all other development and construction. It is also recognized that this type of housing is important to city residents. The purposes of this section is to help ensure that future manufactured home development will be of a quality and design that is most compatible with the existing "conventional", "site-built" or UBC homes. These standards are in addition to any already existing requirements that may be contained in the HUD Code, this chapter or other applicable codes.

(Ord. 225, passed 10-20-1994, § 17.1)

   (A)   The provisions of this section shall apply to those areas single-family residential areas delineated on the city zoning map with the exception of mobile home parks.

   (B)   The provisions of this section shall apply to all manufactured homes that are placed on individual tax lots outside mobile home parks, including lots within an approved mobile home subdivision or planned unit development that is designed and approved specifically for manufactured housing.

   (C)   Any manufactured home that was placed legally in the community prior to the effective date of these standards is considered a legal nonconforming use if it does not comply duly with these standards. A dwelling may be occupied and maintained. If the dwelling is ever relocated within the city, or rehabilitated to an extent greater than 50% of its appraised market value, it shall, at that time, be made to conform to the requirements of this section also to the minimum HUD Code requirements that are in effect at that time.

   (D)   Placement of a manufactured home on an individual lot shall be reviewed for compliance with this chapter and with these standards prior to issuance of a building or placement permit. A certificate of occupancy shall be issued only when the dwelling has complied with all applicable standards and requirements.

(Ord. 225, passed 10-20-1994, § 17.2)

   (A)   Outside mobile home parks, the owner of a manufactured home shall also be the owner of the tax lot on which the home is placed. No individual lots or portions of lots outside parks shall be rented or leased for the placement of a manufactured home. However, a home and lot may be rented or leased together as a single unit. An exception may be taken by the approving authority of the city in the case of a temporary dwelling, a caretaker's residence or similar circumstances.

   (B)   Upon installation on the site, the owner shall ensure the removal of all appliances or other attachments that were necessary for the transport of the home to the site, but that are not necessary for the residential use of the structure; including wheels, axles, tongues, trailers and the like.

   (C)   All manufactured homes shall be connected to any and all public utility lines, as required of any other single-family dwelling, at the time of initial installation or, in the case of an older home, at the time of relocation or major rehabilitation.

   (D)   Manufactured homes shall be installed in compliance with the skirting as required by State Department of Commerce rules O.A.R. 813-23-050 through 813-23-070.

   (E)   The home shall be placed to provide a minimum clear space under the structure's lowest supporting beam of 18 inches. Access to this space shall be provided by an access way at least 18 inches by 24 inches in size in a location that is most convenient to under-structure utility connections, but that is not at the low point or water collection point.

   (F)   An under-structure drainage system shall be designed and constructed to ensure that water will drain properly to the street or other approved storm drain or collection area. Site preparation prior to the home's installation shall ensure that the excavation is tapered toward one end or a center channel for efficient drainage, and that a drain line or pump is installed to remove any water that may collect.

   (G)   Installation, support and tie-down requirements must meet State Department of Commerce rules in O.A.R. 813-23-050 through 813-23-070.

(Ord. 225, passed 10-20-1994, § 17.3)

   Manufactured homes are permitted on individual lots, subject to all of the following design standards, consistent with O.R.S. 197.307(5). Exception: The following standards do not apply to units which existed within the city prior to the effective date of this chapter.

   (A)   Floor plan. The manufactured home shall be multi-sectional and have an enclosed floor area of not less than 1,000 square feet.

   (B)   Roof. The manufactured home shall have a pitched roof with a slope not less than three feet in height for each 12 feet in width (14 degrees).

   (C)   Residential building materials. The manufactured home shall have exterior siding and roofing which in color, material and appearance are similar or superior to the exterior siding and roof material used on nearby residences (e.g., horizontal wood or wood-appearance siding is considered "superior" to metal siding and roofing).

   (D)   Garages and carports. The manufactured home shall have a garage or carport constructed of like materials when nearby residences have carports or garages. The city may require an attached or detached garage where that would be consistent with the predominant construction of immediately surrounding residences.

   (E)   Thermal envelope. The manufactured home shall be certified by the manufacturer to meet the thermal envelope requirements equivalent to those for a single-family dwelling constructed under the State Building Code. Evidence demonstrating that the manufactured home meets "Super Good Cents" energy efficiency standards is deemed to satisfy the exterior thermal envelope certification requirement. Additional manufacturer's certification shall not be required.

   (F)   Placement. The manufactured home shall be placed on an excavated and back-filled foundation and enclosed at the perimeter such that the manufactured home is located not more than 16 inches above grade, and complying with the minimum set-up standards of the adopted State Administrative Rules for Manufactured Dwellings, Chapter 918. Where the building site has a sloped grade, no more than 16 inches of the enclosing material shall be exposed on the uphill side of the home.

   (G)   Foundation skirt. Manufactured homes foundations shall be fully skirted.

   (H)   Prohibited. The manufactured home shall not be located in a designated historic district.

(Ord. 225, passed 10-20-1994, § 17.4)

   (A)   Within 60 days from the time of removal of a manufactured home from its site, the owner of the property shall ensure the removal of all foundations, supports, blocks, piers and other materials that will not be necessary for the future development or use of the property.

   (B)   Following removal of the manufactured home, the owner of the property shall immediately disconnect all utility services to the property, cap connections to the sewer and water source.

   (C)   Should the property owner fail to perform the requirements of divisions (A) or (B) above, the city is authorized to perform the work and place a lien against the property in the event the work is not done within 60 days in the case of division (A) or within 14 days in the case of division (B).
