Relating to the authority of a municipality to regulate within its extraterritorial jurisdiction.

SB 1509 prohibits Texas municipalities from adopting or enforcing local ordinances (such as zoning or building codes) in areas outside their official city boundaries but under city planning control (extraterritorial jurisdiction). Cities may still provide essential services like water or sewer to residents in these areas through direct agreements. The bill amends several local government code sections to clarify that municipalities can designate industrial zones in their extraterritorial jurisdiction and must explain annexation impacts on planning authority. This primarily affects how cities manage development and services in surrounding rural areas and their relationships with residents in those zones.
