Spokane adopts the International Fire Code through SMC Chapter 17F.040 with Spokane Fire Department amendments, capping unprotected residential propane storage and requiring permits for larger tanks under WAC 296-24-475.
Single-family residences in Spokane may keep small portable propane cylinders for grills and patio heaters with no permit, typically limited to two twenty-pound cylinders connected and a few spares stored outdoors away from ignition sources. Larger stationary tanks for home heating, generators, or fireplaces require a Spokane Fire Department permit and must meet International Fire Code Chapter 61 setbacks, anchoring, and signage rules. Tanks over 125 gallons water capacity need at least a ten-foot setback from buildings and property lines. The Washington Department of Labor and Industries WAC 296-24-475 governs commercial storage and licensed gas-fitter installations.
Unpermitted oversized tanks and setback violations can produce SFD correction notices, civil penalties under SMC Chapter 17F, and order to remove or relocate tanks before reoccupancy.
