Summary

Iowa Code Chapter 101 and the State Fire Marshal's LP-gas rules regulate propane storage, installation, and dispensing universally across the state, adopting NFPA 58 standards. Local jurisdictions cannot weaken these technical requirements but may enforce them.

Rules promulgated pursuant to this chapter shall have uniform force and effect throughout the state and no municipality or political subdivision shall enact or enforce any ordinance or regulation inconsistent or not in keeping with the statewide rules. Provided that nothing in this chapter shall in any way impair the power of any municipality when authorized by other law to regulate the use of land by comprehensive zoning or to control the construction of buildings and structures under building codes or restricted fire district regulations. Provided, further, that the size, weight and cargo carried by vehicles used in the transportation or delivery of flammable liquids or liquefied petroleum gas shall be governed by the uniform provisions of the motor vehicle and highway traffic laws of this state and local ordinances therein authorized.

Full Breakdown

Iowa Code Chapter 101 grants the State Fire Marshal authority to adopt and enforce rules for liquefied petroleum gas storage and handling. Iowa Administrative Code 661 Chapter 226 incorporates NFPA 58 (Liquefied Petroleum Gas Code) by reference, governing tank sizing, setbacks, anchoring, dispensing equipment, and installer certification. All LP-gas installers and service technicians must hold state certification. Tanks above specified thresholds require permits and inspections. Cities lack authority to waive these technical safety standards, though local fire codes may impose additional siting or operational requirements consistent with state rules.

Violations & Penalties

Violations of the LP-gas code are simple misdemeanors under Iowa Code 101.21, with civil penalties available and certifications subject to suspension or revocation.

Frequently Asked Questions

Can a homeowner install their own propane tank in Iowa?

No. Iowa requires LP-gas installation, connection, and service be performed by a certified LP-gas installer registered with the State Fire Marshal under Iowa Code 101.1.

What size propane tank requires permits in Iowa?

Permitting thresholds depend on tank capacity and use, but generally tanks above 2,000 gallons water capacity require state plan review and inspection per NFPA 58.

Can Iowa cities add propane rules?

Cities may enforce the state code and add reasonable siting requirements through fire codes, but cannot reduce safety standards established by Iowa Code 101 and IAC 661: 226.
