Full Breakdown

Minn. Stat. 299F.011 authorizes the Minnesota State Fire Marshal to adopt the State Fire Code, which incorporates NFPA 58 governing liquefied petroleum gas. The code sets mandatory minimum separation distances between propane tanks and buildings, property lines, and ignition sources based on tank capacity. Residential 20-pound cylinder storage is generally limited to outdoor placement; larger tanks (100+ gallons) require greater setbacks. Minn. Stat. 326B.804 also regulates LP gas installer licensing. These code requirements form a statewide minimum; local jurisdictions may adopt stricter requirements through zoning but cannot reduce state-mandated safety distances or licensing.

Violations & Penalties

Propane storage violations of the State Fire Code are misdemeanors with fines up to $1,000. Unlicensed LP gas work carries additional penalties under Minn. Stat. 326B.082.

Frequently Asked Questions

Can I store propane tanks in my garage?

Generally no for tanks over 1 pound. NFPA 58 as adopted by Minnesota State Fire Code prohibits indoor storage of most consumer propane cylinders. Tanks should be stored outdoors, upright, in well-ventilated areas.

How far must my propane tank be from the house?

Distance depends on tank size. A 100-gallon tank requires 10 feet from buildings and property lines under NFPA 58. Larger tanks require greater distances. Consult your installer or fire marshal for specifics.

Do I need a licensed installer for propane work?

Yes. Minn. Stat. 326B.804 requires LP gas installation work to be performed by licensed installers. Unlicensed work is illegal statewide and may void insurance coverage in case of incident.
