Washington State Geospatial PortalThe Washington State Parcels Project provides a statewide data set of tax parcels that cover those counties that currently have digital tax parcels. Attribute data has been normalized so that the field names are the same across all counties. The data set contains the tax parcel identification number, situs addresses, the Department of Revenue land use codes, any county-specific land use codes, improvement and land values, and a link to the county's assessor's website for parcel information (if it exists).ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/98029557c8114462aaec982de09d7824_1engState of Washington Geospatial Open Data PortalPublicFile Dates [Washington (State)]Web servicesWashington (State)Last Modified: 2026-04-08
