HB 282 amends Chapter 242 of the Texas Local Government Code, granting certain counties the authority to unilaterally amend agreements with municipalities regarding subdivision regulations in their extraterritorial jurisdictions (ETJs) under specified conditions. Specifically, this authority applies only to counties with populations over 370,000 that contain more than six municipalities, each with populations under 2,000. The bill permits counties to transfer exclusive jurisdiction for regulating subdivision platting for parcels larger than 10 acres, intended for residential use with smaller lot sizes, and that are not covered by existing annexation agreements or interlocal agreements. HB 282 also allows for arbitration of agreement amendments every 10 years under certain conditions, promoting a structured resolution process for counties and municipalities on regulatory jurisdiction. The Act will take effect immediately upon receiving a two-thirds majority in both legislative chambers; otherwise, it will take effect on September 1, 2025​.
