Summary
Texas assigns no regulatory wildfire hazard zones and no wildland-urban-interface building code to unincorporated Williamson County; drought burn bans by the Commissioners Court are the county's only wildfire-driven restriction.
On the request of the commissioners court of a county, the Texas Forest Service shall determine whether drought conditions exist in all or part of the county. The Texas Forest Service shall make available the measurement index guidelines that determine whether a particular area is in drought condition. Following a determination that drought conditions exist, the Texas Forest Service shall notify the county when drought conditions no longer exist.
Full Breakdown
Unincorporated Williamson County has no mapped fire-severity zones, no defensible-space mandate, and no wildland-urban-interface construction code, because Texas counties lack general zoning and building-code authority. The Texas A&M Forest Service publishes wildfire-risk maps, but they carry no regulatory force. The county's operative wildfire tool is a temporary outdoor-burning ban the Commissioners Court adopts under Local Government Code 352.081 once the Texas A&M Forest Service confirms drought conditions.
Violations & Fines
No wildfire-zone building penalties exist; burning during an active drought burn ban is a Class C misdemeanor with a fine of up to $500.
