Summary
Hayward caps how much propane a mobile home site can store and dictates exactly how the cylinders sit. Municipal Code Sec. 5-3.550, part of the city's mobile home park regulations, limits sites to two cylinders of no more than 100 pounds each, bolted to a concrete pad and kept away from structures.
No more than two (2) cylinders of not more than ten (10) gallons capacity each shall be located on any trailer coach, and shall be securely but not permanently fastened to the trailer coach hitch bracket and shall not be located under or within a trailer coach. No more than two (2) cylinders, none of which shall have a greater capacity than one hundred (100) pounds, shall be located on a mobile home site. All such cylinders shall be installed on a firm concrete or masonry foundation and firmly secured in a vertical position. All materials used for such installation shall be non-combustible. Cylinders not connected for use shall not be stored in any mobile home park. Any liquefied petroleum gas cylinder on a mobile home site, except those permitted on the hitch, shall be installed on the rear half of the mobile home site with a minimum of four (4) feet from the nearest mobile home or other structure.

Full Breakdown
Sec. 550 sits in Article 3 of Chapter 5, Hayward's Mobile Home Regulations, so its numeric limits apply to mobile home parks and trailer coach sites rather than to propane tanks at a conventional single-family house. For a trailer coach itself, the code allows no more than two cylinders of not more than ten gallons capacity each, which must be securely but not permanently fastened to the trailer coach hitch bracket and kept off the ground, not located under or within the coach. For the mobile home site more broadly, up to two cylinders are allowed, capped at one hundred pounds each, and every cylinder has to sit on a firm concrete or masonry foundation, secured upright with noncombustible mounting materials; disconnected cylinders cannot be stored anywhere in the park at all.
Placement matters too: any cylinder other than one mounted on a trailer hitch must go on the rear half of the site, at least four feet from the nearest mobile home or other structure. The article backs the storage limits with related safety rules nearby: Sec. 560 requires safety-valve discharge to vent away from any cylinder and at least five feet horizontally from any building opening below the discharge point, Sec. 565 bans readily ignitable material within ten feet of any LP-gas cylinder, regulator, or vaporizer, and Sec. 570 bans recharging any LP-gas cylinder anywhere inside park boundaries.
Violations & Fines
Sec. 5-3.520 puts enforcement of the mobile home park fire provisions, including the LP-gas rules, in the hands of the Hayward Fire Department, measured against National Fire Protection Association minimum standards; existing parks out of strict compliance can continue only if the Fire Chief has approved an exception that does not create a distinct hazard. Sec. 5-3.620 lets any enforcement agency with jurisdiction enter a park to inspect structures, sites, and facilities and require compliance, and violations run through the Code's general penalty section, Sec. 1-1.05, as an infraction escalating to a misdemeanor after repeat offenses.
