Scheduled Maintenance: Thursday and Friday, July 9th and 10th
A major server upgrade will take all services on gismaps.kingcounty.gov and gisdata.kingcounty.gov offline during this time. This means that web mapping applications such as iMap, Parcel Viewer, and My Commute, plus data layers in the King County GIS Open Data portal will be unavailable.

The upgrade may not require the full two days. Status reports will be posted here.

Parcel Viewer makes searching for King County parcel information easy.  You can search by address, search by parcel number, or you can just zoom in on the map and click on a parcel. Once a parcel is selected,  you will get direct links to the King County Assessor’s eReal Property report and the Districts and Development Conditions report.
