King County Assessor Residential Unit Types and Sizes

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 (KCA) data has been compiled to create a dataset of unit types and sizes by tax parcel identification number (PIN). 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. See the data in action in this dashboard. The table includes attribute data from the King County Assessor tables that characterize the use, number of units, number of bedrooms and building square footage (net) for all buildings that indicate a residential use. Due to the way KCA reports the data, some records are for all units within individual buildings (residential and commercial building records), while other records are for the combination of unit type and number of bedrooms (apartment and condominium records) on a particular property (called complex in the table). Therefore there may be many records for any given PIN. Some unit counts and type assignments have been imputed based on other data to allow characterization of the complete data set. Other fields have been added to aid in classification for planning purposes such as the complex category. Every effort is made to characterize the data accurately. Spatial overlay data for various City of Seattle reporting geographies 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. 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.
