Hi Jachym,

The first place I would look for USA parcel data is data.gov. The portal 
could be considered as an official gov aggregator of data. Therefore, if 
a gov agency has it then there you should find it (open or just 
reference to it).

Open Knowledge[1] is conducting a worldwide open data census[2]. This 
year, they introduced land ownership info. I am copy-pasting here what 
has been submitted by volunteers on US, related to the subject:

"It does not seem that federal / national government has a database... 
The Bureau of Land Management has a pretty antiquated website[3] that 
does not have a great cadastre survey page. There is a company[4] that 
sells parcel-level data, and a client they note is the government. The 
state of Montana has a pretty good cadastre map[5] and Oregon[6] 
something similar but I don’t think there is a national map that has all 
the aggregated cadastre maps."

I would mention that the submitted info has not yet been reviewed.

Best regards,
