The Ohio Fire Code (OAC 1301:7-7-61) governs propane storage statewide, not a county rule. In heavily populated areas the aggregate capacity of any one installation cannot exceed 2,000 gallons water capacity, and permits are required above set thresholds.
Hamilton County has no separate propane ordinance; LP-gas storage follows Ohio Fire Code Chapter 61 (OAC 1301:7-7-61), enforced by your local fire code official. Within limits restricting LP-gas storage to protect congested areas, paragraph 6104.2 caps any one installation at 2,000 gallons water capacity. A permit is required for stationary containers over 2,000 gallons, all rooftop ASME containers, or multiple containers exceeding 4,000 gallons aggregate (6101.2). Small barbecue-size cylinders for home use are largely unregulated, but tanks may not be installed on roofs (6104.3.1), and setback tables govern larger tanks near buildings and property lines.
Storing propane over permitted quantities without a permit can bring fire-code citations and orders to remove or relocate containers.
