Milpitas, CA Fire Regulations: Propane Storage (2026)

Propane storage and use in Milpitas is regulated under the California Fire Code, which the city adopts in Title V, Chapter 300 of the Municipal Code. Liquefied petroleum gas (LP-gas) is covered by Fire Code Chapter 61. For typical residential use, small DOT-specification cylinders such as the 20-pound tanks used on barbecue grills and patio heaters are permitted, but cylinders should be stored and used outdoors, kept upright, and separated from combustible materials. The Fire Code sets minimum separation distances for LP-gas containers stored outside awaiting use or resale: under the outdoor-storage provisions (Section 6109.12), aggregate quantities up to several hundred pounds may be stored at zero feet from an important building but must be kept at least 10 feet from combustible materials and away from sources of ignition. Storing larger quantities, installing a fixed/stationary tank, or operating an LP-gas system above the thresholds in the Fire Code requires Fire Department review and an operational or installation permit, and tanks must meet separation distances from buildings, property lines, and ignition sources based on their water capacity. Cylinders should never be stored inside living spaces or used indoors except for very small listed appliances. Because Milpitas adopts the current California Fire Code by reference, residents and businesses should confirm exact cylinder limits, permit thresholds, and setback tables in the adopted edition (the city adopts the current California Fire Code; recent editions include 2019, 2022, and 2025) or with the Milpitas Fire Prevention Bureau before storing larger amounts.
