Permits
King County Permits provides land use, building, and fire regulatory and operating permits, code enforcement services, and a limited number of business licenses to the unincorporated areas of King County.
Effective January 1, 2025, all permit development agencies in Washington—including Unincorporated King County—will implement State Bill 5290.
By the end of this year, the King County Council will adopt legislation to implement this bill for King County. Changes are coming to the permitting process, including permit fees, submittal and review requirements, and clear expectations on permit timelines for both county permitting teams and permit applicants. More details will be posted on this page in December.
