Houston's oldest firehouse still standing—Fire Station No. 7, located at 2403 Milam St. in downtown Houston—is undergoing a renovation and expansion, according to the Houston Planning and Development Department.

The move came after the Houston Archaeological and Historical Commission issued a certificate of appropriateness for the renovation in January 2020.

These updates include life safety and upgrades to put the building in compliance with the Americans with Disabilities Act. It also involves an expansion to the museum's abilities for showcasing displays within the historic footprint of the firehouse, hosting events and parties, and meeting the minimum requirements for Houston ISD field trips.

Fire Station No. 7—nicknamed “Old 7’s”—is the home of the Houston Fire Museum. It is also a city of Houston Protected Landmark, a Texas Historic Landmark and listed in the National Register of Historic Places.

Designed by architect Olle Lorehn, the Romanesque-style building opened in 1899 and remained an active fire station until its replacement was built in 1969.
