Property research tools, 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 condominium/apartment complex name. 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.

Recorded documents (deeds, plats, surveys, etc.)
The King County Recorder's Office is able to record documents pertaining to property definitions and ownership. Certain documents from 1991-current can be viewed online. The eReal Property Report links to the relevant documents on this site.

The Permitting Division of the Department of Local Services is responsible for zoning, land use and permitting for all areas in unincorporated King County. The Citizen Permitting Portal allows you to perform searches, export data from searches, view workflow with comments (where applicable), view inspections, view related records and submit code enforcement complaints. Registered users have access to additional functions, such as scheduling inspections and attaching documents.

Property Tax Online Payment
This King County Treasury Operations web page offers property tax statements and payment options. A parcel number is required to start. The eReal Property reports can take you directly to this system via the "Property Tax Bill" link which will automatically fill in the parcel number from the report.
