Search results for each parcel include links to the eReal Property Report (see below) from the Department of Assesments and the KCGIS Center-produced Districts and Development Conditions Report (see below).

Online property reports and documents

eReal Property: The King County Department of Assessments offers online searchable access to their Property Information System on the eReal Property web page. Users can search by address, parcel number or property name (as for a condominium or apartment complex). This is the place to start your search for property information when you don't need to find or view the property on a map.

KCGIS Districts and Development Conditions Report: This report provides detailed information on electoral, planning and administrative districts and designations. As with eReal Property, searches can be conducted by address, parcel number or condo name as well as links to many other King County or local jurisdiction resources. Parcel Viewer search results and the eReal Property Report each link to the Districts and Development Conditions Report.

Property Taxes: The King County Ecommerce web site offers property tax statements, payment options and other tax information. This site requires a parcel number for the property of interest. The eReal Property Report links directly to this report and automatically fills in the parcel number.

Recorded documents, such as deeds, plats, surveys, etc: The King County Recorder's Office scans and records all official documents pertaining to property definitions and ownership. These documents can be viewed and downloaded. The eReal Property Report links to the relevant documents on this site.

King County DDES (planning, permitting and zoning): The King County Department of Development and Environmental Services (DDES) is responsible for zoning, land use and permitting for all areas in unincorporated King County. The DDES web site offers, among other things, an online report of permitting activity for parcels in unincorporated King County. Parcel Viewer search results link to these permit history reports. For parcels located within an incorporated area, that jurisdiction is responsible for this information. Many local jurisdictions in King County offer this information on their own websites.
