Summary

Stanislaus County's Fire Code amendments exempt small barbecue propane tanks from the LP-gas installation permit that otherwise applies countywide. Under amended Section 6101.2, a container of five gallons of water capacity or less used for barbecue cooking needs no fire-code permit, as long as it's used and stored outside of buildings: the same exemption tier that covers small retail cylinders.

Section 6101.2 of the 2025 California Fire Code is hereby amended to read as follows: LPG Permits. Permits shall be required as set forth in Sections 105.5 and 105.6. Distributors shall not fill an LP-gas container for which a permit is required unless the fire code official has issued a permit for installation for that location. Exceptions: 1. Containers not exceeding five (5) gallon water capacity, used for barbecue cooking, when used and stored outside of buildings. 2. Approved containers not exceeding sixteen and four-tenths (16.4) ounces when displayed for sale in mercantile occupancies. 3. Factory installed containers for recreational vehicles not exceeding ten (10) gallon water capacity. 4. Factory installed tanks that are permanently attached to recreational vehicles.

Full Breakdown

' That covers the standard propane-cylinder grill setup most homeowners use on a patio or balcony area outside a building, no fire-code installation permit is needed for that size and use. 4 ounces, factory-installed recreational-vehicle containers up to ten gallons, and permanently attached RV tanks, none of which apply to a standalone barbecue setup, but they show the ordinance draws its line specifically at the five-gallon threshold and the 'outside of buildings' condition for grill tanks. 2.

Violations & Fines

Using or storing a barbecue propane container larger than five gallons water capacity without the fire-code installation permit required by Section 6101.2, or storing any LP-gas container inside a building where the outdoor-use exemption doesn't apply, is a Fire Code violation under Chapter 16.55 that the Fire Chief can cite, with penalties running from a misdemeanor fine of up to $1,000 and six months in jail to a lesser infraction at the district attorney's discretion.

Frequently Asked Questions

Do I need a permit for my backyard grill's propane tank in Stanislaus County?
No, as long as it's a standard-size tank. Amended Fire Code Section 6101.2 exempts 'containers not exceeding five (5) gallon water capacity, used for barbecue cooking, when used and stored outside of buildings' from the installation permit the section otherwise requires for LP-gas containers.
Can I store my propane grill tank inside my garage?
The exemption only covers tanks 'used and stored outside of buildings,' so moving a barbecue propane container into an enclosed garage or shed takes it out of the five-gallon exemption in Section 6101.2 and back under the general LP-gas installation-permit requirement in Sections 105.5 and 105.6 of the Fire Code.
What size propane tank triggers a fire-code permit for outdoor cooking equipment?
Anything over five gallons of water capacity. The county's amendment to Section 6101.2 draws the exemption line at 'five (5) gallon water capacity,' so larger commercial-style barbecue tanks or bulk cylinders fall back under the standard LP-gas container permit requirement enforced by the fire code official.
