How to read Seattle construction activity
Seattle construction activity starts in the public permit record, before every proposed project becomes a finished building. An application shows intent; review and correction cycles show work moving through SDCI; issuance authorizes the permitted scope; and completion records the city’s final status. Start with active Seattle construction permits when you want the current pipeline, or use linked projects to group related records at the same site.
The permit pipeline separates applications, issued permits, and completions, while the plan-review dashboard shows how long review takes and how correction cycles affect timing. Those measures describe the city’s permitting process; they do not prove that construction has started on site.
Use neighborhood activity to see where permits cluster and contractor activity to trace firms attached to public records. Declared permit value is useful for comparing the scale of filings, but it is an applicant-reported estimate rather than a verified construction budget.

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.
