Source & methodology

Built from Seattle public records

Building Seattle organizes Seattle Department of Construction and Inspections records into searchable permits, addresses, projects, contractors, and neighborhoods.

Permit values are declared permit values, not verified total project costs. Some project and entity relationships are inferred from source records and should be read with the methodology in mind.

Common questions

About the data

What can I search on Building Seattle?
Search permit records by address, permit number, contractor, neighborhood, project description, permit type, status, and other fields exposed by the permit browser.
Where does the data come from?
The base records come from Seattle Department of Construction and Inspections public data. Building Seattle cleans, links, and enriches those records into research views.
How current is the data?
The ingestion pipeline is scheduled daily. This page reports the latest successful ingest separately from the latest permit event date so freshness is not confused with source activity.
What does “permit value” mean?
It is the declared value attached to the permit record. It is not a verified total project cost and may exclude land, design, financing, related permits, later changes, and other project costs.
