When is an inspection required?

(1) Before we issue an insignia, each unit manufactured or converted must be inspected as many times as required to show compliance with this chapter.
Note:
Each commercial coach must have a serial number so we can track inspections.
(2) Before we issue an insignia, each commercial coach must be inspected at the manufacturing location as many times as required. Inspections may include but are not limited to:
(a) A "cover" inspection during construction of the unit before the electrical, plumbing, mechanical, and structural systems are covered;
(b) Insulation and vapor barrier inspection, if required; and
(c) A final inspection after the commercial coach is complete.
(3) If we discover a violation during inspection, we will issue a notice of noncompliance. You can correct the violation during the inspection. If you cannot correct the violation during inspection, you must leave the item uncovered until we approve your correction.
(4) If a commercial coach is damaged in transit to the building site or during on-site installation, it must be inspected. This is considered an alteration inspection. (See WAC 296-150C-0240.)
(5) Approved design plans must be available in compliance with the applicable sections of the adopted state codes.
(6) Once your unit is inspected and approved we will attach the insignia.

Double-Wide Commercial Coaches:
(5) Double-wide commercial coaches require only diagonal ties specified in the table in WAC 296-150C-1210. The ties must be placed along the outer side walls.
(6) Protection must be provided at sharp corners where the anchoring system requires the use of external cables or straps. Protection must also be provided to minimize damage to roofing or siding by the cable or strap.
(7) Anchoring equipment must be capable of resisting an allowable working load equal to or exceeding 3,150 pounds and must be capable of withstanding a 50 percent overload (4,725 pounds total) without failure of either the anchoring equipment or the attachment point on the commercial coach.
