Summary
Cupertino caps liquefied petroleum gas storage at any single installation in residential or congested commercial areas at a 2,000-gallon water-capacity ceiling. Municipal Code § 16.40.320 amends California Fire Code § 6104.2, and the fire code official, Santa Clara County Fire Department, decides which parcels count as residential or congested commercial.
6104.2 Maximum capacity within established limits. Within the limits established by law restricting the storage of liquefied petroleum gas for the protection of heavily populated or congested areas, the aggregate capacity of any one installation shall not exceed a water capacity of 2,000 gallons (7,570 L) in all locations of the City of Cupertino which are residential or congested commercial areas as determined by the fire code official. Exception: LPG may be used for industrial operations or when natural gas would not provide a viable substitute for LPG. Portable containers for temporary heating and/or cooking uses may be permitted if stored and handled in accordance with this code.
Full Breakdown
2 for Cupertino: within the limits established by law restricting LP-gas storage for the protection of heavily populated or congested areas, no installation may hold more than a 2,000-gallon water capacity of propane anywhere the fire code official designates as residential or congested commercial. The same section carves out three exceptions. LPG may be used for industrial operations, or where natural gas is not a viable substitute. Portable containers for temporary heating or cooking are permitted if stored and handled to code. And the fire code official may approve, case by case, commercial facilities that refuel portable or mobile LPG containers.
40, administers plan review and inspection for tanks that trigger this cap. Because the ordinance folds directly into the adopted 2025 California Fire Code, any installation permit application for a fixed LP-gas tank above household cylinder size goes through the same construction and operational permit process the county fire department uses for other fire code permits, with valuation-based fees. A property owner planning a bulk propane tank, rather than exchangeable barbecue cylinders, needs fire department sign-off before the tank is set, and the department can deny or condition the location if the aggregate water capacity would exceed 2,000 gallons in a residential or congested commercial area.
Violations & Fines
Violating any Municipal Code storage limit, including § 16.40.320, is a misdemeanor under § 1.12.010, punishable by a fine of up to $1,000, up to six months in jail, or both, unless the city has specifically made it an infraction. Infractions instead carry escalating fines of up to $100 for a first violation, $200 for a second within a year, and $500 for each subsequent one. Under § 1.12.020, each day a violation continues counts as a separate offense.
