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.

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.

    The 2021 Uniform Plumbing Code with its Chapter 1 excluded, plus Appendix A on sizing the water supply system, under KMC 15.20.145. Administration comes from KMC Chapter 15.30 instead.
