  1. Section 104 CDBG
  2. Free readiness scan

Free to build · Section 104 has been in effect since October 1, 2026

See what your city actually owns.

No list to upload? Buildability runs the grantee-owned undeveloped parcel inventory for your jurisdiction from county records and shows you what we find.

Most cities have never put that list together. Your staff reviews every row before anything is published under your name. Building and checking your inventory is free. Publishing it is an annual licence, priced by your FY26 CDBG allocation.

What arrives in your inbox

Four artifacts. Not features.

Your grantee-owned parcel list

Every parcel the county assessor attributes to your jurisdiction, with the shell-vs-attributed distinction spelled out. Not our guess about what you own: the records that already exist, put in one list.

Undeveloped parcels flagged

Parcels that appear undeveloped based on assessor use codes and building footprints. Your staff confirms line by line. The flag is a starting point, not a claim.

Section 104 schema-ready format

CSV, GeoJSON, and JSON exports formatted to the reference schema so the file is drop-in for your publishing surface: website, GIS portal, or an open data hub.

A methodology memo for your file

One document naming the source, the observation date, and the method. Enough that a HUD monitor reading your certification file sees the work behind the number.

The four tests you have to pass

A ladder that ends in certification.

  1. Publicly accessible

    A resident can find it starting from your own website.

  2. Searchable

    A queryable database, not a posted PDF or spreadsheet.

  3. Grantee-owned

    Land the jurisdiction itself owns — not the county, not the land bank.

  4. Undeveloped identified

    Vacant parcels distinguishable from developed holdings.

  5. Your jurisdiction certifies

    With its counsel, from a file that shows the work behind every row.

From 42 U.S.C. § 5304(b)(7), added by the 21st Century ROAD to Housing Act (Public Law 119-101, signed July 11, 2026).

What this is not

Three things we don’t do.

  • We do not decide which parcels are “undeveloped.” Your staff does.
  • We do not certify compliance. Your jurisdiction certifies.
  • We do not use your name or logo publicly without written approval.

The certification decision is yours and your counsel’s. The scan is evidence for your file, not a substitute for your judgment.
