Fee schedule

Building permit fee
NO PERMIT AMOUNTS ARE PRINTED HERE FOR SPOKANE, AND THE CODE SECTION YOU WOULD GO TO IS EMPTY. Show full citationNO PERMIT AMOUNTS ARE PRINTED HERE FOR SPOKANE, AND THE CODE SECTION YOU WOULD GO TO IS EMPTY. SMC 17F.040.060 is titled "Fees" and its entire text is "Section 108 of the IBC is deleted." - it removes the model building code's fee provisions and puts nothing in their place. The city publishes a "Development Services Fee Schedule 2026", named on its Accela permit portal; THIS GUIDE HAS NOT OPENED THAT SCHEDULE and does not state what is in it. Ask the Development Services Center. AND BE CAREFUL WHO ASKS YOU FOR MONEY: the city's own portal carries a fraud alert stating that it "will never request payment through emailed wire transfer instructions."

Inspection process

    Tips

    • A 24 inch frost depth governs your footing depth - do not copy a shallower detail from a milder part of the state
    • Spokane's wind figure is an ultimate speed; check which measure any comparison uses
    • Inspections are scheduled through the Accela Citizen Access portal by registered users

    Spokane, Washington has adopted: SPOKANE NAMES NO EDITION. SMC 17F.040.010 adopts "the Washington State Building Code (chapter 19.27 RCW and chapter 19.27A RCW) as modified by chapter 51-50 WAC", and lists the "International Building Code (IBC), current adopted Edition, as published by the International Code Council, including Washington State amendments, ICC/ANSI A117.1, and the current adopted Edition International Existing Building Code". The phrase "current adopted Edition" does the work of a year.; THE RESIDENTIAL CODE IS ADOPTED WITH THREE WHOLE PARTS CUT OUT. SMC 17F.040.010 adopts the "International Residential Code, current adopted Edition (except Part IV - Energy Efficiency, Part VII - Plumbing, and Part VIII - Electrical) as published by the International Code Council, and chapter 51-51 WAC; and Appendix Q: Dwelling Unit Fire Sprinkler Systems, WAC 51-51-60105". Energy, plumbing and electrical come from elsewhere.; The same section adopts the "International Energy Conservation Code, current adopted Edition, chapter 51-11C and 51-11R WAC."; Spokane splits construction law across eleven chapters of Title 17F: General Provisions (17F.010), Alternative Methods and Materials for Mixed-use Residential Buildings (17F.020), Boiler and Pressure Vessel Code (17F.030), Building Code (17F.040), Electrical Code (17F.050), Elevator Code (17F.060), Existing Building and Conservation Code (17F.070) and Fire Code (17F.080) among them.; RCW 19.27 - the Washington State Building Code applies statewide.. Local amendments apply — see the Spokane overview page for the full list.

    Spokane publishes a Frostline Depth of 24 inches in SMC 17F.040.105, so footings must bear below that. That figure is local: it is set by the city's own amendment to IRC Table R301.2(1), not by the state code, and a neighbouring jurisdiction may publish a different one.
