About Maine parcel data

Parcel data in Maine is maintained county by county, which is why the schemas differ so widely: each assessor names its own columns, sets its own update cadence and publishes on its own terms. Nothing here is normalised across counties and nothing is live — each file is the snapshot it says it is.

3 counties are published so far, and every one of them is free to download. The rest are listed anyway, with their boundaries and their record estimates, because knowing where a county's data actually lives is worth something too.

Wanted in Maine

These counties have no published dataset and pay a multiplied credit award to whoever supplies one first. Filling one opens it for everybody.

The other half

Have parcel data for a county we don't?

If you already hold a county's parcel layer — from work, from a records request, from a portal that has since gone dark — you can publish it here. It becomes a free download for everyone who comes looking, and a verified upload earns credits toward the counties that aren't free.

You never need credits to download a published county. Contributing is how you reach the fresh vintages and the unopened community uploads.
