Federal deadline —

On October 1,every city publishes its vacant land.

Public Law 119-101 requires every CDBG grantee — roughly 1,245entitlement cities, urban counties, and state programs — to publish a searchable database of the undeveloped land it owns. Buildability™ tracks readiness against the four statutory tests and scores every parcel the moment it’s listed.

Sep 2026Model-agnostic reasoning layerThe reasoning layer runs model-agnostic across three frontier-model tiers — fast, default, and top — picked per query by a complexity router. A lookup does not pay top-tier prices and a due-diligence question does not settle for a fast one.

FAQ

Frequently asked questions.

Does this work in my area?

Yes — all 50 states. Sources are queried live at run time, so coverage doesn't depend on us pre-loading your county.

How is the Buildability Score™ calculated?

Nine weighted factors — zoning, flood, seismic, soil, radon, wildfire, utilities, terrain, and lot geometry — with weights tuned by region (flood 24% in Florida, terrain 20% in California). The methodology is versioned and frozen: same inputs, same number, forever.

How accurate are the reports?

Every finding is queried from its government dataset on every fresh run. A factor with no data drops out of the score instead of being estimated.

Can I export and share results?

Yes — every report exports as a presentation-ready PDF, and paid deliverables include IC memos, decks, and certificates you can put in front of a lender or committee.

Can I try before buying?

Absolutely. The live Score is free on any address — every factor, cited, no credit card. The live Score map and Geo chat are free forever.

What does it cost after that?

One report is $99, and it licenses that parcel for a year — every deliverable, free re-runs, and 12 months of monitoring. Volume slides to $79 and nothing expires. Teams can take Pro at $289/mo with a shared pool and 3 reports included.

Is there a mobile app?

The web app is fully responsive — score properties, read reports, and chat from your phone or tablet without installing anything.
