Joins to an address on centroids, 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.

Where it comes from

County assessor taxpayer of record and taxpayer mailing address, seven counties

Records retrieved 2026-09-07 — the oldest capture date among the layers behind this file, because data is no fresher than its stalest input.

What this layer cannot answer is stated in full on the system card — read it before quoting a figure.

What you may do with it

Creative Commons Attribution 4.0 International (CC BY 4.0). Share it, change it, build a product on it, sell that product — all fine. The one condition is credit: say it came from Brick & Mortar and link back.

Records published by county assessors. Government data held by a Minnesota state agency or political subdivision, presumed public under the Minnesota Government Data Practices Act (Minn. Stat. ch. 13) and published by the agency itself.

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.
