Homeowners may store small consumer cylinders (≤25 gallons aggregate) without a permit, but larger quantities, transfer operations, and tank installations require LACoFD review and adherence to NFPA 58 setbacks. Carson's refinery overlay also means strict South Coast AQMD rules on stationary sources.

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?
Yes for permanent tanks. Any LPG installation in Carson requires an LACoFD operational/installation permit under California Fire Code §105.5.30 and must meet NFPA 58 setback and design standards.
Lancaster FAQ
Do I need a permit for my backyard 20-pound BBQ tank?
No. Residential aggregate quantities of 10 gallons or less — typically two 5-gallon (20-pound) cylinders — are exempt under Title 32 §6101 if used for cooking, heating, or similar household purposes.
How far from my house must a 250-gallon tank sit?
IFC §6104 requires at least 10 feet from buildings and property lines for tanks above 125 gallons up to 500 gallons, plus a 10-foot vegetation-free zone. LACoFD inspection confirms placement before fueling.
Can I refill my own propane cylinder?
Only certified attendants at permitted dispensing stations may refill DOT cylinders. Self-refilling from a bulk tank is unlawful under Title 32 §6109 and creates an immediate fire-marshal stop-use order.
