A few key phrases to help you find your county of choice are: Assessor’s lot map, Assessor’s Parcel map, County Property Viewer.
Just add the name of the county you need info from, plus one of the key phrases, and bam. You’re in business.
Hope that helped someone else.

The requirements for doing an import are here:

And there’s nothing wrong with doing a bit of piecewise improvement with @streetcomplete in the meantime.
