Frequently asked questions about storm shelter installation in Llano County
How much does a storm shelter cost in Texas?
In-ground concrete shelters run $5,000–$10,000 installed. Above-ground steel safe rooms run $6,000–$12,000. Larger multi-family or garage-integrated shelters can reach $20,000+. Prices vary by soil (Hill Country limestone means excavation surcharges) and shelter type (FEMA 320-compliant vs standard). All installers on this page are ATSA (American Tornado Shelter Association) members.
Do storm shelters qualify for the Texas rebate?
Some counties participate in TDEM's Individual Safe Room Rebate Program, which reimburses up to 75% of shelter cost (max $3,000) for pre-approved installations. Availability varies by county and funding cycle. Ask each installer whether they are on the approved contractor list for your county — an unapproved installer disqualifies you from the rebate even if the shelter itself meets FEMA 320.
What is the difference between FEMA 320 and ICC 500 storm shelters?
FEMA 320 is the residential standard (single-family homes). ICC 500 is the commercial code applied to larger community shelters. Both require the shelter to withstand a 250-mph windborne debris impact. Every reputable Texas installer offers FEMA 320-compliant units. Ask for the manufacturer's certification letter and third-party testing report before install.
How long does storm shelter installation take?
Above-ground steel shelters install in 4–8 hours. In-ground concrete shelters take 1–3 days depending on excavation difficulty. Add 4–8 weeks for shelter fabrication if custom. Most installers stock standard 4x6 and 6x8 units for faster turnaround. Best time to install is October–March — outside tornado season means less waiting list pressure.
