Which addresses have a lead water service line
A property not in this file is one the city's inventory does not list, which is not the same as non-lead.
The file
99,833 Minneapolis premises in the city's own inventory: 36,214 lead, 128 galvanized requiring replacement, 33 unknown, 63,414 non-lead. 92,037 placed on a Hennepin parcel by address. Minneapolis only.
99,833 rowsCounties in this file: Hennepin · 18 columns available · free, no account, no rate limit.
Joins to an address on lat, lon, 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.

An em dash means the record is blank, and that is the source's gap rather than ours. Across the whole file: service type is blank on 95.0% of rows, year built is blank on 8.4% of rows, use (assessor class) is blank on 8.2% of rows.

Where it comes from
City of Minneapolis Public Works — Service Line Inventory (ServiceLineInventory_Public)
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

Records published by City of Minneapolis. 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:

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.
