Free Washington property lines map

Yes. This map draws Washington parcel boundaries from the Washington State Geoportal's public statewide parcel layer (all 39 counties) on satellite imagery. It is free, with no account, no trial, and no app to install. Search an address or zoom in, then tap any parcel to see its site address and parcel ID.

From the Washington State Geoportal, which publishes the layer as a public web service. The map asks that service for the parcels in view each time you move it, so you see the state's current copy rather than a stored one. The state last refreshed it in April 2026. Washington’s 39 county assessors supply the parcels; the statewide layer carries boundaries and parcel numbers, and site addresses where the county provides them.

No. Parcel maps are drawn from deeds and tax records for assessment, and lines can be off by several feet or more, especially in rural areas. They are good for finding a property and getting a sense of its shape and size. For a fence, a building setback, or a boundary dispute, hire a licensed land surveyor, whose survey is the legal record.

They are good tools and they cover every county in the country, which is what their subscription pays for. If you only need Washington, the state already publishes the parcel lines for free, and this map simply puts them on satellite imagery you can search.
