    King County Tax Parcel Centroids with select City of Seattle geographic overlays

    Metadata Updated: October 11, 2025

    PLEASE NOTE: If choosing the Download option of "Spreadsheet" the field PIN is reformatted to a number - you will need to format it as a 10 character text string with leading zeros to join this data with data from King County.
    King County Assessor data has been summarized to the tax parcel identification number (PIN) and City of Seattle spatial overlay data has been assigned through geographic overlay processes.  This data is updated periodically and is used to support the analytical and reporting functions of the City of Seattle long-range and policy planning office.
    The table includes attribute data from the King County Assessor as well as spatial overlay data for various City of Seattle reporting geographies.  These geographic attributes are assigned as "majority rules" by land area in cases where multiple geographies span a single tax parcel.
    KCA tax parcels are created by King County for property tax assessment and collection and may not match development sites as defined by the City of Seattle (single buildings may span multiple tax parcels), may be stacked on top of each other to represent undivided interest and vertical parcels, or may be made up of several sites that are not contiguous.  Every effort is made to accurately summarize key tax parcel attributes to a single PIN.  
    Attributes include parcel centroid locations in latitude/longitude and Washington State Plane X,Y.  To get polygon representation of the data please see King County's open data page for parcels and join this table through the PIN field.  Please be aware that the King County Assessor site address is not a postal address and may not match other address sources for the same property such as postal, utility billing, and permitting.

    See the detailed data dictionary for more information.
