About Public Land Index

We believe data transparency can help communities grow.

Public Law 119-101 turns records that were once hard to find into a public asset — and we help local governments meet the requirement quickly, easily, and affordably.

Why it matters

Transformative legislation.

The 21st Century ROAD to Housing Act (Public Law 119-101, signed July 11, 2026) is one of the most consequential housing laws in a generation. At a moment when the country is short millions of homes, Congress decided that the public land already owned by cities and counties might be part of the solution. The law’s new 42 U.S.C. 5304(b)(7) requires every CDBG grantee to publish a searchable, public database of undeveloped land. That single change turns sometimes hard-to-find parcel records into a public asset a community can use.

We find that exciting. A vacant lot nobody remembered the city owned can become affordable housing, a park, a childcare center, or a small business. Residents, developers, and nonprofits can finally see what is possible. Our goal is to help communities comply with this requirement quickly, easily, and affordably.

Our purpose

Public infrastructure, built to last.

Public Land Index (PLI) exists to help local governments comply with the public land database requirement quickly, easily, and affordably. The requirement takes effect October 1, 2026, and most jurisdictions do not have the specialization or capacity to build a compliant public database on their own.

Our team brings the capacity to assemble it, publish it, and keep it current — so your staff can stay focused on serving the community, not standing up new compliance infrastructure.

Who we serve & what we believe

Built for the people who serve communities.

We work with CDBG entitlement grantees, state CDBG programs, and the planning and compliance consultants who serve these communities.

  • Searchable & accurateData should be searchable, accessible, and accurate — traceable to the public records it comes from.
  • Focused on communityKeeping you focused on work in your community, not on new compliance requirements.
  • Simple & easyCompliance should be simple and easy — a finished database, not a project you have to manage.
