When you need this permit
- NO MECHANICAL CODE IS ADOPTED LOCALLY, AND THE ABSENCE IS BOUNDED. Title 16 has eleven chapters — 16.02 Building Permits, 16.08 Dangerous Buildings, 16.16 Moving Buildings, 16.32 Radio Antenna, 16.36 Fire Code, 16.40 Fire Department Permit Fees, 16.48 Fire Hydrants, 16.50 Fire Flow, 16.52 Automatic Fire Extinguishing and Fire Alarm Systems, 16.65 Electrical Inspections and 16.71 Interceptors — and none is mechanical. MLMC 16.02.020 adopts appendices to the state building code and does not name a mechanical code.
- THAT IS NOT THE SAME AS MECHANICAL WORK BEING UNREGULATED. The base state building code is established by statute here rather than adopted by the city, so the state mechanical provisions reach Moses Lake without a local adoption sentence. HOW A MECHANICAL PERMIT IS ISSUED AND PRICED IS NOT ASSERTED — MLMC 16.02.085 sets fees for permits “issued pursuant to this chapter” by council resolution, and the resolution was not opened.
- >>> MOSES LAKE ADOPTS NO MODEL CODE AND NO WAC CHAPTER. IT ADOPTS APPENDICES. MLMC 16.02.020 opens: “Pursuant to Chapters 19.27 and 35.21 RCW the state building code is established. Effective July 1, 2004, the following appendixes to the state building code are adopted for use within the city”. The base code is not adopted by the city at all — it arrives by operation of state statute, and the ordinance only picks up the appendices the state leaves optional. SO THERE IS NO EDITION YEAR AND NO EDITION PHRASE IN THE BASE ADOPTION, BECAUSE THERE IS NO BASE ADOPTION. Des Moines adopts the WAC chapters themselves, which is already a step removed from naming a model code; Moses Lake does not even do that. The audit rule keys on the absence of a year, and here there is not even a sentence for a year to be absent from. A YEAR-CONTEXT TRAP SITS IN THE SAME SENTENCE: “Effective July 1, 2004” is the date the appendix adoptions took effect, not an edition. THE SUPPLEMENTARY CODES DO CARRY AN EDITION PHRASE, AND IT IS ONE ALREADY SEEN: MLMC 16.02.020(D) adopts the Uniform Code for the Abatement of Dangerous Buildings, the Uniform Housing Code and the International Swimming Pool and Spa Code, each at “most current edition” — the same wording SeaTac and Pullman use, now a third and fourth city on that phrase.
- MLMC 16.02.050(G) replaces IBC and IRC Section 108.3: “The determination of value or valuation under any of the provisions of this code shall be made by the building official. The value to be used in computing the building permit and building plan review fees shall be the total value of all const[ruction]…” — the remainder of that subsection is not reproduced here. Because the fee schedule is a council resolution that is not part of the code, the valuation rule is the only part of the fee calculation the code publishes.

MLMC 16.02.085: “All fees for permits issued pursuant to this chapter shall be established by a resolution of the City Council.” No dollar amount appears in the chapter and the resolution is a separate document. Show full citationHide
MLMC 16.02.085: “All fees for permits issued pursuant to this chapter shall be established by a resolution of the City Council.” No dollar amount appears in the chapter and the resolution is a separate document. >>> THE FIRST FEE EXEMPTION IN THIS WASHINGTON SET, AND IT IS WORTH KNOWING ABOUT. 16.02.085(A): the fees “shall not apply to single-family dwellings or duplex dwellings when all the following conditions are present: 1. The residential structure is constructed for low income families as defined by the Community Development Director. 2. The structure is being constructed by an organization classified as a 501(c)(3) nonprofit organization by the United States Internal Revenue Service.” Both conditions, not either. PLAN REVIEW IS A PUBLISHED PERCENTAGE OVER AN UNPUBLISHED BASE: 16.02.085(B) requires it “at the time of submitting the submittal documents” and sets it at “sixty-five percent (65%) of the permit fees as established” — the same 65% Walla Walla publishes, but Walla Walla prints the base table and Moses Lake does not.MLMC 16.02.087 doubles the cost of starting early and says plainly why.

MLMC 16.02.087 doubles the cost of starting early and says plainly why. An investigation fee “shall be collected whether or not a permit is then or subsequently issued” and “shall be equal to the amount of the permit fee required by this code”, with a minimum matching the fee resolution's minimum. THE CODE CALLS IT WHAT IT IS: “This fee is an additional, punitive fee”. No other city in this Washington set uses that word; SeaTac and Walla Walla impose the same doubling and describe it neutrally.MLMC 16.02.085(C) publishes a refund rule: any fee “erroneously paid or collected”, then “not more than eighty percent (80%) of the permit fee paid when no work has been done under a permit”, and not… Show full citationHide
MLMC 16.02.085(C) publishes a refund rule: any fee “erroneously paid or collected”, then “not more than eighty percent (80%) of the permit fee paid when no work has been done under a permit”, and not more than eighty percent of the plan review fee in the parallel case. Note “not more than” — 80% is a ceiling on the Building Official's discretion, not an entitlement, which is a weaker guarantee than Tumwater's flat 80%.Review timeline

Tips
- THERE IS NO LOCAL MECHANICAL CHAPTER IN TITLE 16 — eleven chapters, none mechanical. Because the state building code is established by RCW rather than adopted locally, the state's mechanical provisions apply without a local adoption sentence. Confirm the permit route with the city rather than inferring it from the code's silence.
- The fee resolution covers permits “issued pursuant to this chapter”, so ask which schedule line a mechanical permit falls under.
