Summary
Chelan County requires manufactured, park model, and factory-built homes and commercial coaches to pass five inspection stages before occupancy: site location, footings and foundations, setup and installation under state WAC standards, skirting, and a final check of grading, landings and steps. The Department of Community Development ties each inspection to the placement permit issued under Chapter 3.12.
Each manufactured home, park model home, factory-built home or commercial coach permitted shall be subject but not limited to the following inspections: (1) Site location to assure compliance with approved site plan; (2) Footings and/or foundations as deemed necessary; (3) Setup and installation to verify compliance with Chapters 296-150M, 296-150P, 296-150F, and 296-150C WAC; (4) Skirting and skirting framing; (5) Final to include finish grading, landings and steps which comply with Chapter 3.04.
Full Breakdown
Section 3.12.060 lists the required inspections tied to the placement permit required by Section 3.12.040 for a manufactured home, park model home, factory-built home or commercial coach in unincorporated Chelan County. The five stages: (1) site location, verified against the approved site plan; (2) footings and/or foundations, as deemed necessary by the building official; (3) setup and installation, checked against WAC 296-150M, 296-150P, 296-150F and 296-150C, the state manufactured-home installation standards; (4) skirting and skirting framing; and (5) a final inspection covering finish grading, landings and steps built to Chapter 3.04's standards.
The permit application goes to the Department of Community Development in the form it prescribes, with documentation showing compliance with Chapter 3.12 and other applicable chapters (Section 3.12.040). Water supply and sewage disposal must be approved by the Chelan-Douglas Health District before the county issues the placement permit (Section 3.12.030(5)). The county has not separately codified a stage-by-stage inspection sequence for conventional site-built single-family construction beyond adopting the IBC/IRC by reference in Chapter 3.04; the manufactured/mobile-home sequence in Section 3.12.060 is the only inspection stage list written out in full in the county code.
Violations & Fines
Placing or occupying a manufactured home, park model home, factory-built home or commercial coach without passing the required inspections, or without the underlying permit, is a misdemeanor under Section 3.12.070. Each day the violation continues is a separate offense, punishable by a fine of up to $500.00, up to 90 days in jail, or both, on top of any permit and inspection fees still owed to Community Development.
