About California parcel data
Parcel data in California 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.
32 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 California
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.
