C. Appendix E, Manufactured Homes, is amended to read as follows:
This chapter is enacted as an exercise of the police power of the county for the benefit of the public at large. It is not intended to create a special relationship with any individual, or individuals, nor to identify and protect any particular class of persons.
The purpose of this chapter is to provide minimum standards to safeguard life or limb, health or property, and public welfare, by regulating and controlling the installation of manufactured homes on building sites within the county.
It is not the intent of this chapter to impose liability upon the county for failure to perform any discretionary act. Rather, it is the intent of this chapter to place the obligation of complying with its requirements upon the installer. Nothing contained in this chapter shall be construed to relieve from or to lessen the responsibility or liability of any person for injury or damage to persons or property caused by or resulting from any defect of any nature in any manufactured home installation work performed by said person or in any manufactured home installation equipment owned, controlled, operated or used by him; nor shall Whatcom County, or any officer, agent, or employee thereof, incur or be held as assuming any liability by reason or in consequence of any permission, certificate of inspection, inspection or approval authorized herein, or issued or given as herein provided, or by reasons or consequence of any things done or acts performed pursuant to the provisions of this chapter.
1) SCOPE
This chapter sets forth rules and regulations to regulate and control the installation of manufactured homes on building sites, establishes an administrative procedure for the issuance of permits, and provides for the inspection of manufactured home installations.
2) DEFINITIONS
a. ADMINISTRATIVE AUTHORITY is the Department of Planning & Development Services, the Building Services Division, and the Whatcom County Building Official.
b. BUILDING OFFICIAL is the Building Services Division Manager.
c. BUILDING SITE is any site proposed for the location of a manufactured home including sites within mobile home parks.
d. HUD is the Federal Department of Housing and Urban Development.
e. INSTALLER shall either be the owner or a State licensed mobile home installer.
f. MANUFACTURED HOME means a structure designed and built to comply with the Washington State Department of Labor and Industry’s rules and regulations for MANUFACTURED homes and commercial coaches.
g. MOBILE HOME is a transportable, factory-built dwelling unit constructed prior to June 15, 1976 (prior to enactment of National Manufactured Housing Construction & Safety Standards [NMHCSS] Act of 1974).
h. PERMANENT FOUNDATION means concrete blocks on a concrete footing or slab, or other approved engineered foundation systems.
3) GENERAL INSTALLATION REQUIREMENTS
a. Manufactured homes installed on building sites shall be installed in accordance with the provisions of this chapter and all applicable local, state, and federal codes, ordinances, and statutes.
b. Manufactured homes shall be installed in compliance with the manufacturer’s installation recommendations or according to NCSBCS/ANSI A225.1-1994; permanent foundation requirements. The manufacturer or dealer shall send two copies of its approved installation recommendations to the purchaser of the manufactured home. Two copies shall be submitted with the building permit application.
c. No person, firm, partnership, corporation, or other entity may install a manufactured home unless he/she owns the manufactured home, or is a licensed manufactured home installer.
d. All manufactured home installations shall comply with the requirements of the IRC Section R403.1.7.3, Foundation Elevation, and with the following; On graded sites, the top of any exterior foundation shall extend above the elevation of the street gutter at point of discharge or the inlet of an approved drainage device a minimum of 12 inches plus 2 percent. The Building Official may approve alternate elevations, provided it can be demonstrated that required drainage to the point of discharge and away from the structure is provided at all locations on the site. The following provisions shall be made to prevent standing water under and around a building or structure prior to the final inspection. The finished grade and elevation under the building shall be above the ground drainage flow of the land around the building to prevent surface or sub-surface water from draining to the space under the building, provided that other approved alternates such as drain tile, exterior grading to a point lower than the interior drainage of the building or an approved sump pump may be used, and provided further that the alternate method to be used shall be shown on the building plans. An approved sump pump system shall in no case be connected to the sanitary sewer system. In all instances where a drainage or sump pump system is installed under the structure there shall be provided, in the foundation wall, an access crawl hole which shall be no more than 20 feet from the main drain cleanout. To facilitate the drainage of water, the building site shall have at least a 2% gradient towards approved drainage facilities from building pads. However, this may be waived by the building official provided that the permittee can demonstrate that due to the nature of the site this would be impractical and that an approved alternate will be used. If water appears under the building within a period of 12 months after the final inspection of the building or structure, the builder shall be responsible for providing the drainage of the same, and provided further that the builder has not complied with the requirements of Section 1804.7 herein, concerning drainage. Thereafter, the owner of the building shall be responsible for providing drainage of the same, except where owner and builder agree otherwise.
e. In those areas that are recognized as floodplains by the Washington State Department of Ecology or the Federal Emergency Management Agency, or hazardous because of the probability of earthquakes, ground slides, avalanches, or high winds, the building official may set requirements that are necessary to lessen the hazards. Manufactured homes in a floodplain must be installed per FEMA recommendations as outlined in GUIDELINES FOR THE INSTALLATION & ANCHORING OF MANUFACTURED HOUSING IN WASHINGTON STATE, (Sept. 20, 1996.) Used mobile homes older than 1976, require a fire/life safety inspection by the State Dept. of Labor & Industries prior to building permit submittal. Manufactured homes installed on sites that are sloping or have poor drainage shall be installed in accordance with installation recommendations, provided by a professional engineer or architect licensed in the state of Washington.
4) PERMITS REQUIRED

a. On building sites other than those in mobile home parks, the installer of the manufactured/mobile home shall request a footing inspection after the placement of the footing forms and rebar and prior to pouring or placing the footings, a tie-down inspection and a final inspection after all aspects of the installation have been completed. For mobile home park installations, the installer shall request a final inspection after all aspects of the installation have been completed. All requests for inspection shall be made one working day before such inspection is desired.
b. The manufactured/mobile home may be occupied once the installation has passed final inspection for compliance with the requirements of this chapter and any conditions placed upon the issued permit.
c. If the installation does not comply with the installation requirements of this chapter and the conditions of the installation permit, the local enforcement agency shall provide the installer with a list of corrections that the installer must make. The list of corrections shall state a date by which the corrections must be completed. If the items that require correction do not endanger the health or safety of the occupants, or substantially affect the habitability of the manufactured/mobile home, the local enforcement agency may permit the owner of the home to occupy it.
7) BUILDING SITE PREPARATION
A manufactured home may not be installed on a building site unless the ground at the site has adequate compaction and load-bearing ability to meet the support requirements of (3)(d) or, if the building site is in a mobile home park, the park owner must ensure that the ground on which the mobile home is to be installed has been improved as necessary to provide a proper base for the mobile home and that the area beneath the mobile home has adequate drainage.
