What shares a lot line with a property
What is on each side of a commercial property, from the county's own lot lines. It answers the broker's 'what is next to it', the underwriter's 'what am I exposed to' and the planner's 'what does this site sit against' out of one table.
The file
52,686 commercial parcels · the longest shared line on each side
115,652 rowsCounties in this file: Anoka, Carver, Dakota, Hennepin, Ramsey, Scott, Washington · 28 columns available · free, no account, no rate limit.
Joins to an address on parcel_id, so it can be pointed at one property rather than read whole.
What the rows look like
10 real rows from this file, spread evenly across it rather than taken off the top — every file here is written in some order, so its first rows are never a fair sample of it. These are the default columns, which is what the download button hands over.

Point an AI at it
Every file carries its own source, its capture date and the layer's own warnings in the header, so a model reading one gets the caveats with the numbers rather than the numbers alone. Paste this at an assistant that can fetch a URL:

Everything above the header row is provenance and limits. Read it first,
then answer using only what the rows support.llms.txt describes the whole warehouse the same way — what each dataset holds, which counties it really covers, and what it cannot answer.
