Your city publishes its vacant land on October 1.
We’ll tell you what can be built on it.
Public Law 119-101 requires every CDBG grantee to publish a searchable database of the undeveloped land it owns. Most cities have never assembled that list. We already did.
Free. No signup. See your parcel count in about 20 seconds.

What the lawactually says.
“…the grantee maintains, on a publicly accessible website, a searchable database that identifies all parcels of undeveloped land owned by the grantee.”
From that date, maintaining the database is a certification a grantee makes in order to receive CDBG funds. It applies to entitlement cities, urban counties, and state CDBG programs.
A resident can find it starting from your own website.
A queryable database, not a posted PDF or spreadsheet.
Land the jurisdiction itself owns — not the county, not the land bank.
Vacant parcels distinguishable from developed holdings.
The statute does not define “undeveloped.” HUD has not issued implementing guidance. These four tests are our reading of the statutory text, published so you can check our work — not a federal standard.
One search in.Four tests, one inventory out.
Every grantee page renders the same four-test verdict, the preliminary parcel list, and the Buildability™ Score distribution across those parcels — before any email is asked.
- Four-test readout
Pass / fail chips for each of the four statutory tests, with the observation date on the readout.
- Preliminary parcel inventory
Parcels attributed to your jurisdiction, total acreage, FY26 CDBG allocation, and the county-assessor source line.
- Buildability™ Score distribution
A through F across your parcels. The ones scoring A or B are the parcels that can carry housing without a fight.
We’ll build your inventory.Free.
No pilot, no trial that converts, no card. We assemble the parcel list from county records, format it to the Section 104 reference schema, and hand it to you as CSV, GeoJSON, and a hosted searchable table you can link or embed.
- Parcel list attributed to your jurisdiction
- Section 104 reference schema formatting
- CSV, GeoJSON, and JSON exports
- A hosted searchable table and map you can link or embed
- Line-by-line review sheet for your staff to confirm
- A methodology memo for your CDBG file documenting source, date, and method
- We do not decide which parcels are “undeveloped.” Your staff does.
- We do not certify compliance. Your jurisdiction certifies.
- GIS cleanup, system integration, and ongoing maintenance are separate engagements.
- We don’t use your name or logo publicly without written approval.
The list is free because the list isn’t the product. The question of what can be built on it is.
The list is the deadline.The pipeline is the point.
Congress didn’t require these inventories so cities would have lists. The statute is a housing act. The moment your vacant land is public, the question changes from do you have a database to why isn’t anything being built there.
Buildability™ scores every parcel in your inventory across nine weighted factors — zoning, flood, seismic, soil, radon, wildfire, utilities, terrain, and lot geometry — tuned to your region. You get a ranked list of which parcels can actually carry housing, which need work, and which never will.
Publish
Meet the October 1 certification.
Score
Rank every parcel by what it can support.
Dispose
Take the developable ones to council, RFP, or a developer.
That’s the memo your council asks for in November. It’s also the answer when a developer calls about a parcel and your staff has thirty minutes to figure out whether it’s worth a meeting.
No card at signup. Full refund if we miss SLAs. Cancel any time.
Creating and maintaining the database is a CDBG-eligible activity under 42 U.S.C. § 5305(a)(27). Many jurisdictions can procure services at this scale as a micro-purchase under their own written procurement policy — check your policy and the current threshold at 2 CFR 200.1. [VERIFY: confirm our pilot pricing lands under the threshold before publishing this line]
Nobodyis ready.
We checked every CDBG entitlement city and urban county in the country against the four statutory tests and published the results. Not a sample. All of them. If your jurisdiction is listed incorrectly, tell us and we’ll re-check it within one business day.
Questions your attorney will ask
Does this make us compliant?
No. Your jurisdiction certifies compliance; we do not and cannot. We give you the parcel list, the schema, the hosted table, and a methodology memo for your file. The certification decision is yours and your counsel’s.
HUD hasn’t defined “undeveloped.” How do you decide?
We don’t. We flag parcels that appear undeveloped based on assessor use codes and building footprints, and your staff confirms line by line. Our definition is published so you can adopt, narrow, or reject it.
Where does the parcel data come from?
County assessor records, with ownership attributed by owner name. Every parcel links back to the county’s own record so your staff can verify against the source.
What about land held by our redevelopment authority or a dependent district?
Title questions are yours to resolve. We show what assessor records attribute to your jurisdiction’s name and flag adjacent entities we found so nothing is missed silently.
Why is this free?
Because compliance hosting is a commodity and we’re not a compliance vendor. We want to be the intelligence layer on the land after it’s published.
What’s the catch on the free inventory?
There isn’t one, and there’s no logo use or public naming without your written approval. If you take the list and never speak to us again, that’s a fine outcome.
Can this be embedded on our site?
Yes — link it or embed it so it reads as part of your own site.
Do you have an API?
A REST API and MCP server are in build and not publicly available yet. We’ll tell you when they ship rather than sell you a date.
Buying land,not publishing it?
On October 1, roughly 1,245 jurisdictions publish their undeveloped holdings for the first time. Buildability™ scores all of it — every parcel, every jurisdiction, one national index.
