Houston FAQ
What is the difference between Landmark and Protected Landmark?
Landmark gives 90-day demolition delay only. Protected Landmark requires owner consent, supermajority HAHC vote, and permanently restricts demolition plus major exterior changes for the property.
Can I nominate my building?
Yes. Property owners or any Houstonian can submit nominations to the Planning Department. Owner consent is required for Protected Landmark; standard Landmark can be designated without consent.
Pasadena FAQ
Can I demolish a Recorded Texas Historic Landmark in Harris County?
You can ultimately demolish an RTHL after a sixty-day Texas Historical Commission review, although THC may publicly oppose and remove the marker. State Antiquities Landmarks (SAL) cannot be demolished without a THC permit and full mitigation.
How do I check if my Harris County property is historic?
Search the Texas Historic Sites Atlas at atlas.thc.texas.gov by address or county. The atlas lists RTHL, SAL, National Register, marker, and cemetery designations. Houston properties may also have separate City of Houston landmark or historic district status.
