Most cities have never assembled that list. On October 1, every CDBG grantee is required to publish it. This is the assembly: done, delivered, and yours to review with your staff before you publish it under your own name.

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, assembled.

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. Section 104 certified

    Your file is defensible on October 1.

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).

Fill this out and Buildability will confirm your slot in the first 25, or your place on the waitlist if the queue has filled, within one business day by email. Delivery of the scan itself follows within days of confirmation.

Your email is used to reply and for nothing else. We don’t sell your information and we don’t add you to a mailing list.

What this is not

Naming what we don’t do is what makes what we do defensible.

  • 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.
