Carson FAQ
How many propane tanks can I keep in my backyard?
California Fire Code Chapter 61 limits consumer-cylinder storage at one-family dwellings per Table 6103.2. Small barbeque-size (20 lb) cylinders are fine in the backyard; tanks over 125-gallon water capacity require a permitted installation with NFPA 58 setbacks (≥10 ft from buildings).
Can I store propane on my apartment balcony?
California Fire Code §6109.13 limits residential balcony storage to two cylinders maximum, each no larger than 20 lbs (the typical BBQ-tank size). Larger cylinders are prohibited above grade in multi-family buildings.
Do I need a permit to install a propane tank?

South Gate FAQ
Can I store propane tanks for my BBQ in the garage?
California Fire Code §6109.13 prohibits storage of LP-gas cylinders inside occupied portions of one- and two-family dwellings, including attached garages. Store BBQ propane tanks outdoors, on a hard, well-drained surface, away from ignition sources, and never in a basement or below-grade space.
How many BBQ propane tanks can I have?
California Fire Code §6103 exempts containers up to roughly 1 lb propane (cylinders ≤ 2.5 lb water capacity). Standard 20-lb BBQ cylinders count toward aggregate residential limits. Two spare cylinders (40-60 lb total) outdoors at a single-family home is well within the ~125 gal residential allowance.
Do I need a permit for a 500-gallon tank for an ADU or pool heater?
Yes. California Fire Code §105.5.30 requires an operational permit for LP-gas storage exceeding 125 gallons aggregate. Installation must comply with NFPA 58 setbacks (10 ft for 126-500 gal). Contact the South Gate Building Department for fire code review and a plumbing/mechanical permit.
