AMENDATORY SECTION (Amending WSR 96-18-053, filed 8/30/96, effective 9/30/96)

WAC 468-38-120  ((Oversize manufactured home transport regulations.)) Transport of extra-legal manufactured housing. (((1) The purpose of this section is to supplement the provisions of chapter 468-38 WAC as they relate to the movement of manufactured homes. Where conflicts with other sections of this chapter occur, the following rules apply.

(2) Definitions:

(a) "Manufactured home" means all trailers of the semitrailer type with hitch ball coupler designed as structures for human habitation which may have been subsequently adapted to other uses, which are capable of being towed upon the public highways and are more than thirty-six feet in length and more than eight and one-half feet in width.

(b) "Modular homes and sectional buildings" means any factory-built housing designed for human habitation which does not contain a permanent frame and must be mounted on a permanent foundation. Modular homes or sectional buildings with their own attached running gear which can be towed are considered to be manufactured homes for purposes of this regulation. Modular homes or sectional buildings moved on legally registered trailers are subject to the provisions of chapter 46.44 RCW and the provisions of this chapter of the Washington Administrative Code regulating the movement of overlegal loads.

(c) Oversize permits may be issued to transporters, dealers or owners who shall assume full responsibility while operating under a permit. Operators of tow vehicles and others assisting in the transport must function as agents or employees of the permittee.

(d) A "unit" is a complete or irreducible part of an oversize manufactured home.

(3) Manufactured homes of semi-trailer design whose width, including eaves, exceeds eight and one-half feet but whose box width does not exceed fourteen feet, and/or whose length exceeds fifty-three feet but does not exceed seventy-five feet including tongue, may be moved under the provisions of an oversize load permit issued by the department: Provided, That the permitted oversize limits, incorporating box width and eave location when traveling, are as follows:

(a) The box may not exceed fourteen feet in width.

(b) The box plus eave may not exceed fifteen feet in width.

(c) With any combination of box and eave width, up to fourteen feet, the eave(s) may be traveled on either or both sides.

(d) Any eave in addition to the permitted combination of fourteen foot box and eave(s) shall be traveled on the right side in the direction of traffic.

The procedure for measuring box width shall not include external appurtenances such as door knobs, window fasteners, drip cap at roof edge, clearance lights, load securing devices and closure materials: Provided, That such external appurtenances do not exceed two inches on any side.

(4) Oversize manufactured home permits may be issued as follows:

(a) Annual permits may be issued only to permittees who are qualified as dealers or manufacturers as provided in chapter 46.70 RCW or to transporters licensed as provided in chapter 46.76 RCW.

Annual permits shall apply only to transport of manufactured homes fourteen feet or less in height, above level ground, while being transported.

(b) Monthly permits may be issued to dealers, manufacturers, and transporters under the same conditions as annual permits except that fourteen-foot height limitations may be waived.

(c) Single trip permits may be issued to dealers, transporters and owners for a specific combination of tow vehicle and mobile home to travel from a point of origin to a prescribed destination.

(5) The permittee must have insurance in effect while operating under the permit in the minimum amounts of one hundred thousand dollars - three hundred thousand dollars public liability and fifty thousand dollars property damage. Pilot car operators shall meet the insurance requirements of RCW 46.44.180.

(6) If an accident occurs while transporting a manufactured home under permit, the permittee shall immediately notify the nearest state patrol office if the damage is greater than two hundred fifty dollars to the manufactured home or greater than one hundred dollars to other vehicles or structures. Permission to continue the movement must be obtained from the state patrol.

(7) Dealers selling twelve to fourteen-foot wide manufactured homes must advise the prospective purchaser in writing that not all state highways are approved for the transport of twelve to fourteen-foot wide manufactured homes.

(8) Permits issued in accordance with the Uniform Mobile and Modular Home Transportation Regulations of WASHTO will be subject to those regulations and will be honored by the state of Washington if issued by other states.

(9) Manufactured homes:

(a) Overall dimensions shall not exceed those stated in the permit except for minor protrusions not to exceed two inches, such as door and window hardware. Eaves will be included in the measurement of maximum width. All dimensions shall be reduced to the practical minimum. Manufactured homes having a single eave overhang along their length will be transported to allow for safe passing distances.

(b) The complete system of the manufactured home, including running gear assembly, shall comply with the rules and regulations adopted by the United States Department of Housing and Urban Development (24 CFR 280 (1976) and as thereafter amended). Tires shall comply with applicable Federal Motor Carrier Safety Regulations, Title 49, chapter 111. Those manufactured homes not certified as qualifying to the minimum H.U.D. specifications shall have brakes on at least two axles and on four wheels. Units of sixty feet or more in length shall have at least three full axles, except that twelve-foot wide homes manufactured prior to November 1, 1970, may be moved with a minimum of two axles. The brakes shall be under the control of the driver from the cab of the towing vehicle, and shall be adequate to control the manufactured home and its load. They shall be so designed and connected that they shall automatically apply in case of accidental breakaway from the towing vehicle. A wet-cell or approved battery with a full charged rating of twelve volts will be installed in the manufactured home to actuate electric brakes in the event of a breakaway. The minimum track width between two wheels on the same axle shall be eight feet. Track width shall be measured from the outer edges of the road bearing tread of tires on a single axle. Tires shall have no signs of separation or excessive aging and shall be inflated to the maximum recommended tire pressure and have tread depth no less than 3/32nd inch in any part of tire contacting the road. Recapped or retreaded tires are not allowed. Minimum combined load rating of manufactured home tires must be in excess of their in-transit load. Axles and wheels must be properly aligned to minimize wear and overheating of tires.

(c) The open side of half sections of manufactured homes shall be covered in such a way as to prevent billowing of the covering material.
