Summary
Colorado Springs' amended Fire Code requires an operational permit before storing or using LP-gas once a single container tops 125 gallons water capacity or the combined capacity of multiple containers exceeds 125 gallons, under Section 105.5.29. Installing or modifying the tank system itself triggers a separate construction permit under Section 105.6.15 at the same threshold.
105.5.29 LP-gas. An operational permit is required for: 1. Storage and use of LP-gas where a single container, cylinder, or tank is more than 125 gallons water capacity; or the aggregate capacity of containers is more than 125 gallons water capacity. Exception: A permit is not required for individual containers with a 500-gallon (1893 L) water capacity or less or multiple container systems having an aggregate quantity not exceeding 500 gallons (1893 L) for existing mobile home communities. 2. Operation of cargo tankers that transport LP-gas. 3. One or more LP-gas cabinets associated with a cylinder exchange program.

Full Breakdown
29, as amended by the City, sets the operational-permit trigger for LP-gas (propane) storage and use at more than 125 gallons water capacity, whether that's a single container, cylinder, or tank, or the aggregate of several containers on one property. The section carves out an exception for existing mobile home communities, letting individual containers up to 500 gallons water capacity, or multiple-container systems totaling up to 500 gallons, operate without the permit. Operating cargo tankers that transport LP-gas and running LP-gas cabinets tied to a cylinder-exchange program are separately exempted from the operational-permit list.
15, requires a construction permit for installing or modifying an LP-gas system at the same 125-gallon threshold, so a homeowner or business adding a bulk tank needs sign-off both to build the installation and, once it's running, to operate it. 1 caps an operational permit's life at 365 days before renewal is required. Most residential propane appliances, a typical 100-gallon or smaller backyard tank, fall well under the 125-gallon trigger and need no city permit at all; the rule targets bulk storage.
Violations & Fines
Operating or installing LP-gas storage above the 125-gallon threshold without the required permit exposes the property owner or operator to City Code Section 1.1.201's General Penalty: a fine of up to $2,500, up to 189 days in jail, probation, or a combination. The fire code official can also require corrective installation work or removal of noncompliant equipment before an inspection will clear.
