Short-term rental permit rules in Williamson County, TX — also called Airbnb permits, vacation rental licenses, or STR registration — list the application steps, fees, and operating requirements for hosting.
No STR permit is required in unincorporated Williamson County. Texas counties cannot zone or license short-term rentals, so no registration exists outside city limits. HOA deed restrictions are usually the real limit.
Georgetown, Round Rock, Leander, and other Williamson County cities run their own STR permit programs, but that authority stops at the city line. On unincorporated land the county has no power to require a short-term-rental permit, cap the number of rentals, or inspect them for tourism use, because counties lack zoning authority in Texas. The binding constraint is almost always private: subdivision deed restrictions and HOA covenants, many of which prohibit rentals under 30 days outright.
No county permit means no county citation for operating without one. Deed-restriction violations are enforced civilly by the HOA, which can seek injunctions and recover attorney's fees.
