About Maryland parcel data
Parcel data in Maryland 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.
Nothing is published for Maryland yet. Every county in the state still has a page here with its boundary and its record estimate, and each one opens the moment a dataset lands.
Wanted in Maryland
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.
