Newport Beach, CA Fire Regulations: Propane Storage (2026)

Liquefied petroleum gas (propane/LP-gas) in unincorporated Orange County is regulated under California Fire Code Chapter 61, which OCFA enforces; there is no separate county-specific propane ordinance. Section 6109 governs portable LP-gas containers of 1,000 pounds or less, such as the 20-pound cylinders used for backyard barbecues. The Code prohibits storing LP-gas containers in a basement, pit, above-grade underfloor space, or similar location where heavier-than-air gas could collect, unless that location has approved ventilation; containers must also be kept clear of exits, exit-access doors, and stairways. Container valves on cylinders larger than the nominal 1-pound size must be positioned so the pressure-relief valve communicates with the vapor space. For larger fixed installations, Table 6104.3 sets separation distances - for example, above-ground containers under 125 gallons require 10 feet from buildings and lot lines, and containers of 501-2,000 gallons require 25 feet. Construction documents are required when a single container exceeds 2,000 gallons water capacity or the aggregate exceeds 4,000 gallons (Section 6101.3), and permits apply to container installations. For multifamily properties, propane and charcoal cooking devices are restricted near combustible balconies and construction (see BBQ rules).
