Seattle Construction Permits

Search live Seattle construction permits from public SDCI records. Filter the active permit stream by neighborhood and permit type — or look up any address, permit number, or contractor — then drill into the projects that matter to your team.

How to search Seattle permit records

Start with a street address, permit number, or contractor, then combine the neighborhood, permit type, and status filters to narrow the public Seattle Department of Construction & Inspections record. Each result surfaces the project description, declared valuation, issue date, current status, and linked property or contractor history. The data is refreshed daily.

Permit valuations are project estimates, and a status describes the city's review or issuance workflow rather than proving construction is complete. Read the data methodology, or compare activity across Seattle neighborhoods, contractors, and property records.
