The Washington State Parcels Project provides a statewide data set of tax parcels attributes 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, improvement and land values, and a link to the county's assessor's website for parcel information (if it exists).
