Project Assessment

Submit to King County
Submit your permit application to the King County Department of Local Services, Permitting Division. Applications can typically be submitted online, by mail, or in person. Include all required documentation and applicable fees.

County reviewers will examine your application for compliance with building codes, zoning regulations, and other requirements. This process may involve requests for additional information or clarifications.
Permit Issuance
Once approved, you'll receive your permit along with any required inspection schedules. Post the permit visibly at the job site and ensure all contractors have access to permit documents.
