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.
