Texas does not grant counties general Euclidean zoning authority. Dallas County has minimal unincorporated land, so agricultural zoning decisions largely fall to cities. Local Government Code Chapter 232 governs subdivision platting only.
Unlike Illinois, California, or New York, Texas counties have no general zoning power. Texas Local Government Code Chapter 232 lets counties regulate subdivision platting, lot size, road access, and water and wastewater in unincorporated areas, but counties cannot zone land for specific uses such as agricultural, residential, or commercial. Dallas County is roughly 99 percent incorporated within Dallas, Irving, Garland, Mesquite, Richardson, Carrollton, Grand Prairie, and other municipalities, so most agricultural land is governed by city zoning if any. Remaining unincorporated slivers default to use-by-right under state law plus county subdivision rules. Texas Right to Farm Act protections operate independent of zoning. Most active Texas agriculture occurs in Lower Rio Grande Valley counties.
Subdivision-platting violations in unincorporated Dallas County trigger Public Works enforcement under Local Government Code Chapter 232, with civil penalties and recorded lien remedies. There is no agricultural-zoning enforcement because there is no county zoning.
