Summary

Williamson County sets no setback rules. Texas counties have no zoning power. Only subdivision platting under Local Government Code Chapter 232 applies, and in platted subdivisions HOA deed restrictions set the front, side, and rear yards.

City-specific rules exist: Cedar Park has its own setback rules rules that differ from Williamson County's county-level regulations. If you live in Cedar Park, check the city-specific page instead.

The owner of a tract of land located outside the limits of a municipality must have a plat of the subdivision prepared if the owner divides the tract into two or more parts to lay out: (1) a subdivision of the tract, including an addition; (2) lots; or (3) streets, alleys, squares, parks, or other parts of the tract intended by the owner of the tract to be dedicated to public use.

Full Breakdown

Texas counties cannot zone, so Williamson County imposes no minimum front, side, or rear setbacks in unincorporated areas near Georgetown, Hutto, and Leander. The county's only land-use control is subdivision platting under Local Government Code Chapter 232, which governs how a tract is divided, not where a house sits on a lot. Yard setbacks come from recorded HOA deed restrictions and subdivision plat notes. Inside city limits, municipal zoning applies instead. Floodplain management adds building limits near waterways such as Brushy Creek and the San Gabriel River.

Violations & Fines

The county cannot cite a setback violation in unincorporated areas because none exist. HOAs enforce deed-restriction setbacks through civil action, fines, and liens, not county code enforcement.
