Summary

Williamson County runs no no-knock registry, but a posted "No Soliciting" or "No Trespassing" sign carries legal force: entering after notice that entry is forbidden is criminal trespass under Texas Penal Code Section 30.05.

City-specific rules exist: Cedar Park has its own no-knock registry rules that differ from Williamson County's county-level regulations. If you live in Cedar Park, check the city-specific page instead.

"Notice" means: ... a sign or signs posted on the property or at the entrance to the building, reasonably likely to come to the attention of intruders, indicating that entry is forbidden

Full Breakdown

The county maintains no do-not-knock list in unincorporated areas; enforcement runs through criminal trespass law. Penal Code Section 30.05 makes it an offense to enter or remain on property after notice that entry is forbidden, and the statute defines notice to include a posted sign reasonably likely to come to the attention of intruders indicating entry is forbidden. A clearly posted "No Soliciting" or "No Trespassing" sign therefore turns an unwanted solicitor's approach into a trespass a sheriff's deputy can act on. Cities in the county may keep their own no-knock ordinances.

Violations & Fines

A solicitor who enters posted property or refuses to leave after being told commits criminal trespass, a Class B or Class C misdemeanor, subject to arrest and fine by the sheriff's office.
