When you need this permit

  • KMC 15.20.010 adopts “The 2021 Edition of the International Building Code, excluding Chapter 1, ‘Scope and Administration,’ as published by the International Code Council… together with the amendments set forth in Chapter 51-50 WAC.”
  • PERMIT LIFE IS THREE YEARS for a “commercial, educational, institutional, multifamily, public, industrial or similar structure” (KMC 15.30.245(B)).
  • The building official may grant only “a 30-day extension of time for permits when only the final inspection is remaining and all other work has been approved” (KMC 15.30.245(D)).
  • Kenmore writes its own administrative chapter and amends the IBC section by section: KMC 15.20.015 through 15.20.115 each amend a single IBC section, including Section 3117 “Waterfront Structures”, which KMC 15.20.110 ADDS to the code.

Fee schedule

Permit fee
No dollar figure is published in the code. Show full citationNo dollar figure is published in the code. KMC 15.30.350 says a fee shall be paid “in accordance with the schedule as established by the applicable governing authority” — IT DOES NOT NAME THE BODY — and adds that “the building official is authorized to establish fees for any permit activity not specifically set forth herein”. A plan review fee is due at submittal under KMC 15.30.355. THE VALUATION THE FEE IS COMPUTED FROM IS NOT THE APPLICANT'S NUMBER BY DEFAULT: KMC 15.30.365 requires the applicant to give an estimated value, then provides that valuation “shall be made by the applicant or building official, whichever is higher”, with the official using “the latest edition of the ICC ‘Building Safety Journal’ publication”. Ask the city for the current schedule; it cannot be derived from the code.

Inspection process

    Tips

    • A waterfront structures section was added to the IBC as Section 3117 by KMC 15.20.110 — Kenmore sits on Lake Washington, and that section has no counterpart in the model code.
    • The only extension the code offers is 30 days, and only when the final inspection is the sole outstanding item. Plan the three years as the real budget.

The first city in this Washington series to adopt it by name.; International Wildland-Urban Interface Code — KMC 15.20.180 IS HEADED “International Wildland-Urban Interface Code adopted” AND ITS BODY READS, IN FULL, “Repealed by Ord. 24-0610.” KENMORE DOES NOT ADOPT IT. The heading is the only thing that says otherwise.; NO ELECTRICAL CODE IS ADOPTED IN TITLE 15. Chapter 15.20's sections were enumerated end to end and none adopts the NEC or the Washington Cities Electrical Code, unlike Mountlake Terrace, Mercer Island, SeaTac and Des Moines. KMC 15.30.245(C) nonetheless sets a one-year life for “electrical, mechanical, and plumbing permits not associated with a building permit”. The usual Washington route is inspection by Labor and Industries under Chapter 19.28 RCW, BUT NO SUCH PROVISION WAS FOUND IN THIS TITLE and none is asserted here.. Local amendments apply — see the Kenmore overview page for the full list.

    Only narrowly. KMC 15.30.245(D) lets the building official grant a 30-day extension when the final inspection is all that remains and every other item has been approved. There is no general extension provision.
