Find land zoned for more homes, before it is listed
169,234 parcels across all 351 Massachusetts towns; all 169 Connecticut towns; Wichita, Kansas and Unincorporated St. Louis County, MO are zoned for multi-family and currently hold one house, or nothing at all. They are not for sale, so no brokerage feed contains them. Finding them means joining zoning to current land use across 4,199,209 assessor records.

What a search returns
Every parcel that qualifies, ordered so the ones worth a call come first.
The shortlist, ranked
- A ZIP opens on its top ten, ranked on two measured signals: how long the land has been held, and how far its assessed value per acre sits below other multi-family parcels in the same district
- Each pick says which signal put it there, so the ranking can be argued with rather than taken on trust
- Ranked within the ZIP and within the district — a statewide comparison mostly measures which town a parcel is in
What the lot already supports
- 116,357 parcels carry a unit count drawn from what neighbouring lots of the same size in the same district already hold
- Shown only where at least twenty comparable parcels stand behind it — below that the figure is noise, and a dash is more honest
- Evidence of what fits on the land, not a claim about what would be approved today
Signals on the owner
- 1,302 parcels are recorded as estate-owned and flagged in probate
- Transfers with a date but no price are marked "not a sale" — an inheritance, a divorce or a corrective deed, named for the evidence rather than the inference
- Both are filters, and both are shown as facts rather than predictions
Looking at the parcel
- Every lead sits on the map and links straight to Street View at its own coordinates
- Last sale date and price, filtered for the sentinel dates assessors type when they mean "unknown"
- Filter by acreage, assessed value, town, current use and owner signals; export the result as CSV
- Email alerts on the ZIPs you track, when a parcel newly qualifies
Two ways this gets used
For agents
- A listing pitch backed by what the owner's land is permitted to become, not what it currently is
- Owner names and mailing addresses for direct outreach on parcels no competitor is working
- Farm a ZIP code systematically instead of waiting for inventory
For developers
- Site selection across a whole town before anything is listed or optioned
- Filter by lot size and assessed value to match what a project needs
- Every district links to the municipality's own regulations for the feasibility read

Method and limitations
Stated plainly, because you will be spending money and time on the output.
Zoning is measured, not assumed
A code like R-15 is single-family in one Connecticut town and something else in the next, so we never read the code string. Each district is classified from what is actually built within it, town by town.
Counted by the lot, not the record
Assessors file a condominium once per unit, with no land attached — so a single development can outvote a neighbourhood of houses on what a district permits. We count parcels of land. Districts that read multi-family only through unit records are withheld until someone reads the ordinance.
Verify before you acquire
This is a research tool, not a legal determination. Every district we list links to the town's own published regulations, and only the municipality can tell you what may be built.
Annual source, stated openly
Towns file assessor data by 1 May under CGS §7-100l. That is the freshest public record in Connecticut; we refresh against it rather than imply a live market feed.
Uncheckable codes are marked
A few municipalities file internal zone codes that map to no published district. Those parcels are labelled as unverifiable rather than presented as confirmed.
