San Diego FAQ
Can I store a 20-pound BBQ tank on my apartment balcony?
Generally no. IFC §6109 and most apartment leases prohibit cylinders larger than one pound on balconies of multi-family dwellings. Use an alternative cooking appliance or store the tank at a permitted ground-level location.
Do I need a permit for my home propane grill tank?
No permit is needed for a single 20-pound exchange cylinder for residential cooking when stored outdoors away from ignition sources. Larger tanks, multiple cylinders, or commercial refilling require SDFD permits.
San Marcos FAQ
Do I need a permit to store a backyard propane tank?
Most residential barbecue and patio cylinders under 25 gallons aggregate do not require permits, but installations near buildings must meet Fire Code setbacks.
Can my city ban propane storage entirely?
No. Cities may add reasonable conditions tied to local hazards but cannot prohibit storage that meets state Fire Code standards.
