Yes. Texas law prohibits placing signs on the right-of-way of a public road unless otherwise authorized by law.
House Bill 3611 from the 2025 Texas Legislature did not change the sign rules but changed the rules about the penalties for signs. Prior to pursuing civil penalties for a first offense, a municipality must now notify the owner in writing and allow an opportunity for the owner to remove the sign. No civil penalty can be assessed if the owner removes the sign within the allotted time. The specific time for removing the sign is at the discretion of the municipality issuing the notice.
If you wish to place a sign in a common area that is not in the right-of-way of a public road, you should check with the local municipality or property owners association to confirm whether a sign may be placed at the desired location. When placing signs on private property you must first obtain the written consent of the property owner.
