Summary
Williamson County sets no building height limit. Texas counties lack zoning authority, so height caps in unincorporated areas exist only through HOA deed restrictions. Cities like Round Rock and Cedar Park regulate height inside their limits.
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
No county ordinance caps building height in unincorporated Williamson County. Texas counties have no zoning power, and their only land regulation is subdivision platting under Local Government Code Chapter 232. Height restrictions on a home, barn, or accessory structure come from recorded HOA deed restrictions and subdivision plat notes, not from the county. FAA rules limit structure height near the Georgetown and Taylor airports. Once inside a municipality such as Leander or Hutto, that city's zoning height limits apply.
Violations & Fines
The county issues no height citations in unincorporated areas because it has no zoning authority. HOAs enforce their own height covenants through civil action, not county code enforcement.
