Summary
Williamson County has no lawn grass-height ordinance and cannot zone. In the unincorporated area, uncultivated growth over 36 inches becomes an abatable weeds nuisance under state law; inside subdivisions, HOA covenants set mowing standards.
"Weeds" means all rank and uncultivated vegetable growth or matter that: (A) has grown to more than 36 inches in height; or (B) may create an unsanitary condition or become a harborage for rodents, vermin, or other disease-carrying pests, regardless of the height of the weeds.
Full Breakdown
Texas counties have no zoning power, so unincorporated Williamson County sets no maximum height for a maintained residential lawn. The only height-based tool is Health and Safety Code Chapter 343: rank, uncultivated growth taller than 36 inches counts as weeds and, within 300 feet of another residence or business, the Commissioners Court can order abatement. Mowed turf below that threshold is unregulated by the county. Homeowners inside Georgetown, Round Rock, Cedar Park, Leander, Hutto, and Taylor follow their city codes, and platted subdivisions enforce lawn upkeep through recorded HOA deed restrictions.
Violations & Fines
County weed abatement runs on written notice; if uncorrected the Commissioners Court may abate the growth and assess costs against the property as a lien. HOA lawn violations draw fines under recorded covenants.
