Local permitting and code notes
Houston is in Texas, where Texas has adopted the International Residential Code statewide. ICC 500 is referenced for community shelters in some jurisdictions. Residential storm shelters typically require a permit but not a specific shelter code.. Confirm permit requirements with the Houston building department before signing a contract. Most documented installers handle the permit filing as part of the quote.
What to verify on a Houston installer quote
- The producer holds current ICC 500 testing for the specific configuration being shipped
- The producer appears on the current NSSA producer member list
- The anchoring schedule (bolt size, embed depth, epoxy product, spacing) is written into the quote
- The door's missile impact test report covers the unit as shipped, not a different model
- The quote includes FEMA P-320 documentation if state rebate eligibility matters
