Questions
How often is the Seattle permit list updated?
Seattle updates this open-data feed daily; this page is rebuilt every Monday and covers the seven days before the rebuild. This build covers permits issued 2026-09-15 to 2026-09-22 and was made on 2026-09-22. The source is Seattle SDCI building permits (data.seattle.gov, dataset 76t5-zqzr).
Where does the data come from?
Directly from the public record: Seattle SDCI building permits (data.seattle.gov, dataset 76t5-zqzr). Nothing is estimated; counts and values are exactly what the issuing department published. Permits with no declared value are counted but excluded from value totals.
Can I get the Seattle list with the property owner's mailing address?
Not for Seattle. PermitRadar sells its weekly owner report for Lee County, Florida only (unincorporated Lee County and Cape Coral). This Seattle page is a public permit listing rebuilt every Monday from the city's open data; no owner join is offered for it.
Are these all the permits issued?
Everything the source published for the period at build time, 108 records. Issuing departments sometimes backfill permits days later, so next week's page can include stragglers from this one.
Public record, republished as published. PermitRadar adds counts and ranking only; nothing on this page is estimated. No owner names or mailing addresses appear on this page and none are sold for Seattle.
