Storm shelters in San Marcos, TX

Free quotes for in-garage, in-ground and above-ground storm shelters and safe rooms in San Marcos and across Hays County. We match you with an independent local installer.

Planning a shelter in San Marcos

San Marcos sits on the Balcones Escarpment near the San Marcos River. Floodplain areas are not suitable for in-ground shelters, and FEMA guidance keeps safe rooms out of high flood-hazard areas, so an installer should check your flood zone first.

Shelter options for San Marcos homes

  • In-garage shelters: A steel or concrete unit installed in the garage, either set into the slab below the floor or bolted to the slab as an above-ground room. You reach it without stepping outside.
  • In-ground (underground) shelters: A buried steel, fiberglass or concrete shelter in the yard or under a new slab, entered through a door or hatch at ground level.
  • Above-ground safe rooms: A steel or reinforced concrete room anchored to a concrete slab, inside the home (a closet or interior room) or outdoors on its own pad.

Before you buy

  • Check your flood zone on the FEMA Flood Map Service Center before considering an in-ground unit.
  • Check your HOA rules, and ask the installer who handles the San Marcos building permit.
  • Ask for test documentation for the model and door: ICC 500 and FEMA P-361.
  • Compare prices against the typical cost ranges.
