Full Breakdown
Fire Code § 307.6.1 permits outdoor fireplaces, fire pits, and similar devices fueled by natural gas or liquefied-petroleum gas once the Building Department approves the installation and the unit is built to burn only a gas flame, never wood or solid fuel. At R-3 (single-family) occupancies, combustible construction and vegetation must clear at least 3 feet from the device's vertical flame column; at other residential occupancies the minimum jumps to 10 feet. A Building Department-approved hood and vent can let construction encroach on that clearance zone, and any chimney or vent must carry a spark arrester.
Violations & Fines
Installing or operating a gas fire pit without Building Department approval, or violating the clearance standards, is enforceable as a Fire Code infraction or misdemeanor under § 113.4.2, with OCFA fee-schedule penalties.
