San Antonio's Fire Regulations: The Rules That Matter

Every city handles fire regulations a little differently. In San Antonio, Texas, there are 5 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Propane Storage

San Antonio Fire Code, an amended version of the International Fire Code Chapter 61 adopted under SAMC Chapter 11, restricts residential propane storage to limited aggregate water capacity with stricter rules for multifamily balconies and commercial cylinder exchange.

Wildfire Zones

San Antonio's northwest areas near Camp Bullis and the Hill Country contain wildland-urban interface zones with elevated wildfire risk. The City Manager was authorized under a 2016 ordinance (Ordinance 2018-11-03-0860) to execute interlocal agreements with the Texas A&M Forest Service for fuel reduction services. The International Fire Code as adopted in Chapter 11, Article III applies to brush management and defensible space.

Defensible space violations: fines $100 to $1,500. Non-compliant construction: required upgrades. Insurance companies may decline coverage in high-risk zones without compliance.

Fireworks

All possession, sale, use, transport, and manufacture of fireworks is prohibited within San Antonio city limits and within 5,000 feet of those limits, per the adopted International Fire Code Section 5601.1.3 and Texas Occupations Code Chapter 2154.
