Austin, TX Fire Regulations: Propane Storage (2026)

2 of the local Fire Code amendments (City Code Sec. 25-12-173) confirms that the chapter's general hazardous-materials permit rules apply to storing, using, handling or dispensing LP-gas and to installing or maintaining an LP-gas container, but it carves out household propane use: "a permit is not required for non-commercial use at a single family residence," though the homeowner must still give the fire department location and exposure information under the Fire Protection Criteria Manual. Any single container over 2,000 gallons, or an aggregate over 4,000 gallons water capacity, requires the installer to submit plans regardless of the residential exemption.

The numeric ceiling on where a larger tank can even sit comes from Sec. 2, "Maximum capacity within established limits": storage of LP-gas above 2,000 gallons aggregate is banned citywide, and any above- or below-ground container greater than 24 gallons water capacity and up to 2,000 gallons is prohibited outside of Major Industry (MI) or Light Industry (LI) districts. That 24-gallon threshold is well below a typical 100- or 250-gallon residential propane tank, so larger household tanks are technically outside industrial zoning limits unless the fire code official uses the built-in exception, which lets the official approve the placement of aboveground or below ground containers for single family residential, multi-family residential or commercial occupancies on a case-by-case basis, provided the container is listed, installed per its listing, and zoning and fire-exposure concerns are satisfactorily addressed. A common 20-pound barbecue grill cylinder, well under the 24-gallon line, falls outside this zoning restriction entirely.
