City of Seattle

Development potential and permit history.

Enter an address or a King County parcel pin. The report reads the assessor lot, the city zone, steep-slope critical areas, and Seattle permits matched by address. It covers the City of Seattle only.

Development potential estimate, not a zoning determination. Verify with the City of Seattle and a licensed professional.

An address outside the City of Seattle returns “Not covered yet.” It does not return a blank zone.
