Fairfield FAQ
Can I keep a spare BBQ propane tank in my garage?
One spare 20-pound (5-gallon water capacity) cylinder may be stored in a residential garage if upright, valve closed, and ventilated. Never store cylinders in living spaces, basements, or near heat sources. Outdoors in a well-ventilated, shaded area is always preferred.
Do I need a permit for a 100-gallon propane tank for my home generator?
A typical 100-gallon nominal propane tank is about 120 gallons water capacity—right at the threshold. The Fairfield Fire Marshal generally requires an operational permit plus a building/mechanical permit for the installation. Confirm with the Fire Prevention Division before installation.
Vacaville FAQ
How many propane tanks can I keep at my Vacaville home?
Residential storage of LP-gas containers under 125 gallons water capacity (e.g., 20-lb BBQ tanks, 100-lb cylinders) has no minimum setback under California Fire Code Chapter 61 (adopted by VMC 15.20.271) if CFC §6104.3 installation conditions are met. Larger aggregate quantities or any container over 125 gallons trigger setback requirements and may require a Vacaville Fire Department operational permit.
Can I put a propane tank under my Vacaville house?
No. Because LPG is heavier than air, California Fire Code prohibits LP-gas containers in basements, pits, or below-grade underfloor spaces unless approved mechanical ventilation is provided. Standard residential installations must be at grade level outdoors.
Does my Vacaville propane fire pit need a permit?
Use of a propane fire pit fed by a small residential cylinder does not require a fire permit, but installation of a permanent gas line or a larger propane tank may require both a building/mechanical permit through Community Development and compliance with CFC Chapter 61 setbacks under VMC 15.20.271.
