Permanent outdoor kitchens in Spokane require building, plumbing, electrical, and/or gas permits under SMC Chapter 17F.040 (which adopts the International Residential Code and related codes) when they include utilities or covered structures. SMC Chapter 17C.110 zoning setbacks apply.
Spokane adopts the International Residential Code, International Building Code, Uniform Plumbing Code, and National Electrical Code by reference under SMC Chapter 17F.040 (Construction Codes). Permanent outdoor kitchens require a building permit when they involve gas line extensions (require a plumbing permit and a Washington-licensed plumber under RCW 18.106), 120V or 240V electrical wiring (require an electrical permit issued by Washington Labor & Industries under RCW 19.28), water/drain plumbing (require a plumbing permit), or a roofed structure over 200 sq ft (smaller roofed structures may be permit-exempt per IRC R105.2). Freestanding portable BBQ islands without permanent utility hookups do not require a permit. Gas line installations must be performed by a licensed plumber, pressure-tested per the Uniform Plumbing Code, and inspected by the Spokane Building Services Department. Outdoor kitchen structures count as accessory structures under SMC Chapter 17C.110 (Residential Zones) and must observe the underlying district's setbacks: typically 5 feet side and rear in R1 and R2 districts under Table 17C.110-3, with greater setbacks in RA. Lots in flood zones (Spokane River, Hangman Creek, Latah Creek floodplains) require additional review under SMC Chapter 17E.030 (Flood Hazard Reduction).
Building a permanent outdoor kitchen without permits violates SMC Chapter 17F.040 (Construction Codes) and SMC Chapter 17C.110 (Residential Zones). Code Enforcement administrative penalties under SMC 1.05 typically start at $100-$250 per violation and escalate with continuing violations. Unpermitted gas lines pose fire and life-safety risks and may need to be removed and reinstalled.
