Summary
Carlsbad Municipal Code Section 5.24.280 sets exact clearance distances for propane cylinders and tanks inside licensed auto and trailer parks: no cylinder within five feet of an ignition source or inside an enclosed building, and tanks over 500 gallons must sit at least 25 to 50 feet from the nearest building or property line. Outside trailer parks, the adopted California Fire Code Chapter 61 governs LP-gas storage.
A. No cylinder shall be located within a building enclosed on four sides, nor within a trailer coach, nor within five feet of a source of ignition; nor below ground, nor below ground level, nor with the outlet less than five feet away from any building opening which is below the level of such outlet. ... B. Each tank shall be located with respect to the nearest source of ignition or line of property adjoining, which may be built upon, in accordance with the following table. Vessels and first-stage regulating equipment carrying more than 20 psi pressure shall be located outside the buildings, or trailer coaches... VOLUMETRIC CAPACITY OF VESSELS (in U.S. gallons) MINIMUM DISTANCE: (1) Not more than 500 U.S. gallons, 10 feet; (2) 501 to 1,200 U.S. gallons, 25 feet; (3) Over 1,200 U.S. gallons, 50 feet. C. Regulating or filling equipment on tanks filled on consumers' premises shall not be less than 15 feet from any opening into or under a building... D. Readily ignitable material shall not be permitted within 10 feet of any vessel, regulator or vaporizer.

Full Breakdown
Chapter 5.24 defines an auto and trailer park as any tract renting or holding space for two or more trailer coaches or tent campers, and defines liquefied petroleum gas as petroleum hydrocarbons with a vapor pressure over 26 psi at 100 degrees Fahrenheit (Section 5.24.005). Within those parks, Section 5.24.280 bars any cylinder from sitting inside an enclosed building or a trailer coach, below ground, or within five feet of an ignition source, and requires safety-valve discharge points to stay at least five feet from any building opening below the discharge level.
Tank placement then scales with volume: vessels holding up to 500 gallons need 10 feet of clearance from the nearest building or buildable property line, 501-to-1,200-gallon vessels need 25 feet, and anything over 1,200 gallons needs 50 feet, with any vessel or first-stage regulator rated above 20 psi kept outside buildings and trailer coaches. Filling equipment on tanks serviced on-site must stay at least 15 feet from any below-level building opening, readily ignitable material is barred within 10 feet of any vessel, regulator, or vaporizer (Section 5.24.280), and Section 5.24.285 separately bars charging any cylinder within 10 feet of a building or trailer coach.
The Community and Economic Development Director and the city health officer can permit variations only for fishing-resort-adjacent parks or where relaxing the rule will not endanger public health (Section 5.24.335), and the chapter cannot be read as less restrictive than the state Trailer Park Act (Sections 5.24.325, 5.24.330). None of this reaches single-family homes: outside licensed trailer parks, LP-gas storage falls under the 2025 California Fire Code Chapter 61, adopted in full without amendment at Section 17.04.460 and enforced citywide by the Carlsbad Fire Department.
Violations & Fines
Violating any LP-gas placement standard in Chapter 5.24 is a misdemeanor under Section 5.24.340 once the operator has been served written notice of the violation and refuses to comply. Citywide, a violation of the adopted California Fire Code Chapter 61 is enforced under Fire Code Section 113.4 as amended by Section 17.04.020(B): a misdemeanor punishable by a fine up to $1,000, up to six months in county jail, or both, with each day of continued noncompliance treated as a separate offense.
