1). Foundation System Footings.

a). Footings shall be constructed of either a solid concrete or an approved alternative that is at least 3 1/2 inches thick by 16 inches square; or two 8 inch by 4 inch solid concrete blocks that are laid with their joint parallel to the main frame longitudinal member.

b). Footings shall be:

1). Evenly bedded and leveled;
2). Placed on firm, undisturbed, or compacted soil that is free of organic material.
3). Centered in a line directly under the main frame longitudinal members on both sides of a manufactured home; and
4). Spaced not more than 8 feet apart, and not more than 2 feet from the ends of the main frame. A closer spacing may be required, depending on the load-bearing capacity of the soil.

c). A manufactured home with more than one section must have center line blocking at end walls and at any other point of connection of the sections of the manufactured home that are a ridgebeam bearing support. Blocking is also required at both ends of a door opening that is 6 feet or more wide in an exterior wall.

d). If a manufactured home requires footings on its exterior perimeter, the footings shall be installed below the frost line. Footings for the main frame longitudinal members must be recessed only if frost heave is likely to occur.

e). Footings shall be constructed so that seventy-five percent (75%) of the area under the manufactured home has at least 18 inches clearance between the bottom of the main chassis members and the ground level. The area beneath furnace cross-overs and fireplaces, however, must always have at least 18 inches clearance. At no point under the manufactured home may clearance be less than 12 inches.

2). Foundation System Piers. An installer must build and position piers and load-bearing supports or devices to distribute the required loads evenly. An installer may use manufactured piers or load-bearing supports or devices that are listed or approved for the intended use, or may build piers that comply with the following requirements. All blocks must be concrete blocks.

a). A pier may be made of a single stack of 8 inch by 8 inch blocks if the blocks are not stacked more than three blocks high. A pier made of a single stack of blocks shall be installed at right angles to the main frame longitudinal member and shall be capped with no more than two 2 inch by 8 inch by 16 inch wood blocks or one 4 inch by 8 inch by 16 inch concrete block.

b). A pier may be made of a double stack of 8 inch by 8 inch by 16 inch blocks if the blocks are not stacked more than 5 blocks high. Each row of blocks in such a pier shall be stacked at right angles to the abutting rows of blocks. A wood block must be of hem-fir, Douglas fir, or spruce pine fir. The pier shall be capped with two 2 inch by 8 inch by 16 inch wood or concrete blocks. The pier shall be installed so that the joint between the cap blocks is at right angles to the main frame longitudinal member.

c). A pier may be made with more than five rows of blocks if the stacked blocks are filled with 2,000 psi concrete or mortar. A licensed architect of professional engineer must approve a foundation system that includes a pier that is higher than 72 inches (9 blocks) high, or in which more than 20 percent of the piers exceed 40 inches (5 blocks) high.

d). All blocks shall be set with the cores placed vertically

3). Foundation System Plates and Shims. An installer may fill a gap between the top of a pier and the main frame with a wood plate that is not more than 2 inches thick and two opposing wedge-shaped shims that are not more than 2 inches thick. Wood plates and shims must be of hem-fir, Douglas fir, or spruce pine fir. A shim shall be at least 4 inches wide and 6 inches long. The installer shall fit the shim properly and drive it tight between the wood plate or pier and the main frame to ensure that the manufactured home is level and properly supported at all load-bearing points. A block that abuts a wedge-shaped shim must be solid.

4). Foundation Facia. A manufactured home shall have an approved foundation facia around its entire perimeter. The wood of the facia shall be at least 3 inches from the ground unless it is pressure-treated wood. Metal fasteners shall be galvanized, stainless steel or other corrosion-resistant material.

A manufactured home that is installed on a nonrecessed site and that has a metal foundation facia shall have ventilation openings with a net area of at least 1 1/2 square inches per linear foot. A manufactured home that has been installed on a recessed site or that has a foundation facia that is not made of metal shall have ventilation openings in the foundation facia with a net area of a least 1 1/2 square feet for each 25 linear feet of facia. The openings shall be designed to provide cross ventilation on at least two approximately opposite sides of the manufactured home. The installer shall locate the openings as close to the corners of the manufactured home as practical, and shall cover the openings with corrosion-resistant wire mesh or louvers.

Dryer vents and hot water tank pressure relief valves shall exhaust on the exterior of the foundation facia. The facia for each section of a manufactured home shall have an opening of at least 18 inches by 24 inches, with cover of metal or pressure treated wood, to allow access to the crawl space. The foundation facia must be installed within thirty (30) days after the manufactured home is occupied.

5). Assembly.

a). Sections of a multiple section manufactured home shall be aligned, closed, and securely fastened at the required points along the ridge beam, endwalls, and floor line. Heat ducts, electrical connections and other fixtures and connections required between sections of a manufactured home shall be properly installed. The floor of the manufactured home shall be level within the tolerances given in the following table.

Tolerances may not exceed the following amounts (L equals the clear span between supports, twice the length of a cantilever):

Floor: L/240
Roof and Ceiling: L/180
Headers, Beams, Girders
(vertical load): L/180
Walls and Partitions: L/180

b). The installer shall provide adequate clearance to ensure that the cross-over heat duct does not touch the ground and is not compressed. The installer shall insulate the cross-over duct at the intersection. The installer shall insulate and seal areas of potential air leaks to ensure that the manufactured home is air-tight, and shall seal areas of potential water leaks with metal flashing or trim, if required, and with putty, tape or other approved caulking to ensure the manufactured home is watertight.
