MUD Disclosure (§49.452)

§ 03 · Data moat

● §49.452 Notice

Not in archive

This MUD is not yet in our §49.452 archive. We'll add it on request.

Texas Water Code §49.452 requires districts to publish annual notices with tax rate, bonded indebtedness, and assessed value. Most Harris-area MUDs publish these; a handful managed by Inframark do not.

Request this notice

● What this tells you

The §49.452 notice is the only public document that lists a MUD's exact tax rate, outstanding bond debt, and the assessed value used to compute your taxes — direct from the district, not the MLS. If the district is newer or has more bonds outstanding than its neighbors, your effective tax rate will be higher here than just across the street.
