What's in it

Every construction permit filed with Seattle SDCI, cleaned and deduplicated, then enriched with data the open data portal doesn't have: parcel numbers, review levels, full detail-page descriptions, contractor license numbers, review-cycle counts, and housing unit breakdowns. One UTF-8 CSV that opens in Excel, Google Sheets, pandas, or R — plus a full data dictionary.

Try before you buy

A free 100-row sample with the same 32 columns and real enriched data is available on the product page. If it doesn't have what you need, don't buy the full version. If you do buy and it isn't useful, there's a 14-day no-questions refund.

Why pay for public data?

The raw records are public — the work isn't. The city publishes permits piecemeal through a clunky portal, without contractor licenses, parcel numbers, review levels, or detailed descriptions. Our pipeline scrapes, cleans, deduplicates, and enriches every record so you don't spend a weekend doing it yourself.
