What happens after we receive the professional or firm approved design plan and information?

(1) After we receive your approved design plans and information, we will check the design plans and information to reasonably assure they contain the documents and plan information outlined in our written guidelines for plan reviews as provided to approved licensed professionals. Once accepted we will assign a plan approval number and send a copy of the design plan with the plan approval number to the manufacturer.
(2) If our check of the design plans and information finds that they are not acceptable we will notify you in writing of the reasons why. Unless being audited in accordance with subsection (3) of this section, design plans and information may be corrected and resubmitted for acceptance within 90 days of our notification. We may charge the applicant an additional hourly fee to process revised submittals (see WAC 296-150C-3000).
(3) We may audit design plans approved by a professional engineer, architect, or firm to ensure compliance with this chapter and our written guidelines for plan reviews. Audits may be either random audits or they may be audits of plans that were not accepted in accordance with subsection (2) of this section. The department's audit should not be construed as certifying that the plans are safe.
(4) If the audit finds that the design plans approved by the professionals and firms do not comply with this chapter and our written guidelines for plan reviews, the applicant will be notified and may be required to pay our fees for review and approval of the design plans. (See WAC 296-150C-3000.)

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.

Windstorm protection—Provisions for support and anchoring.

(1) Each commercial coach must have provisions for support and anchoring systems that, when properly designed and installed, will resist overturning and lateral movement of the commercial coach as imposed by the respective design loads. Support and anchoring systems can be installed according to the Table in WAC 296-150C-1210 or designed by a professional engineer.
(2) The manufacturer of each commercial coach is required to make provision for the support and anchoring systems but is not required to provide the anchoring equipment or stabilizing devices.
(3) The manufacturer must provide printed instructions with each commercial coach specifying the location and required capacity of stabilizing devices on which the design is based.
Single-Wide Commercial Coaches:
(4) The provisions made for anchoring systems must be based on the following design criteria for single-wide commercial coaches:
(a) The minimum number of ties required per side is noted in WAC 296-150C-1210.
(b) Ties must be as evenly spaced as practicable along the length of the commercial coach. No more than eight feet open-end spacing must occur on each end.
(c) If continuous straps are provided as vertical ties, they must be positioned at rafters and studs. If a vertical tie and diagonal tie are located at the same place, both ties may be connected to a single ground anchor, as long as, the anchor used is capable of carrying both loads.
(d) Add-on sections of expandable commercial coaches must have provisions for vertical ties at the exposed ends.
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.
(8) Exposed anchoring equipment must have a resistance to weather deterioration at least equal to that provided by a coating of zinc on steel of at least 0.30 ounces per square foot of surface coated.
(a) Slit or cut edges of zinc-coated steel strapping do not need to be zinc-coated.
(b) Type 1, Class B, Grade 1 steel strapping, 1 1/4 inches wide and 0.035 inch thick, conforming with Federal Specification QQ-S-781-G, meets the requirements of this paragraph.
