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.
