About this inventory

Public Law 119-101 (the 21st Century ROAD to Housing Act) became law on July 11, 2026. Effective October 1, 2026, it requires that:

“…the grantee maintains, on a publicly accessible website, a searchable database that identifies all parcels of undeveloped land owned by the grantee.”

Housing and Community Development Act of 1974 §104(b)(7), 42 U.S.C. 5304(b), as added by Public Law 119-101

Accordingly this inventory lists every parcel identified as undeveloped land owned by Collier County, Florida, including right-of-way strips and sub-acre remnants, each labeled by category rather than omitted. Parcels recorded as improved are not part of the inventory. Full sourcing, the undeveloped test, and known limitations are documented on the methodology page.

PREVIEW — not yet the county’s official database. Assembled by Civic Data Works from Collier County Property Appraiser 2025 tax roll (Florida Department of Revenue statewide cadastral, via the Florida Geographic Information Office) joined to the Collier County GIS parcel layer for parcel boundaries and not yet reviewed by Collier County, Florida. Categories are proposed from public records; the county confirms what counts as undeveloped before this page becomes official.
