Spokane ADU rules by jurisdiction
ADU rules differ by jurisdiction. The first step is identifying which one your lot falls under, then reading the current rules for that jurisdiction.
Jurisdiction
City of Spokane
ADU rules for homeowners inside Spokane city limits.
See the rules →Jurisdiction
Unincorporated Spokane County
County ADU rules for parcels outside any city, with the BP-75 and BP-76 sheets.
See the rules →Jurisdiction
Spokane Valley
ADU rules and the permit center for the City of Spokane Valley.
See the rules →Not sure which jurisdiction your property is in? Your county property record lists the jurisdiction, and the cities of Spokane and Spokane Valley each maintain their own permit offices. If your parcel is outside any city, the unincorporated Spokane County rules apply.
