Full Breakdown
2 of the California Fire Code, adopted under Ordinance No. 2025-14, bars charcoal burners and other open-flame cooking devices from combustible balconies and from operating within 10 feet of combustible construction across unincorporated territory served by the Contra Costa County and Crockett-Carquinez Fire Protection Districts. The section sits in Chapter 41, Temporary Heating and Cooking Operations, and targets charcoal grills, wood-fired smokers, and similar open-flame equipment. Three exceptions narrow the rule considerably: it does not apply at all to residential occupancies (Group R, covering houses and apartments), it does not apply where the balcony, deck, or building is protected by an automatic sprinkler system, and it does not apply to small LP-gas cooking devices whose propane container holds 2 1/2 pounds of water capacity or less, roughly the size used on a portable camp grill.
In practice the 10-foot clearance and balcony ban land hardest on non-residential and unsprinklered commercial buildings, restaurants, and multi-tenant structures with wood decks, not on single-family backyards or apartment patios. The fire code official inspects for compliance during routine occupancy inspections and can order a noncompliant grill or smoker removed from a combustible balcony before it becomes a shared life-safety hazard.
Violations & Fines
Violating Section 4104.2 is enforced the same as any other fire code breach: Section 112.4 makes noncompliance an infraction or misdemeanor under Health and Safety Code Section 13871 and Government Code Section 53069.4, with each ten-day period a prohibited condition continues counted as a separate offense. The fire code official can require immediate removal of an open-flame device from a combustible balcony.
