Delaware adopts NFPA 58 (Liquefied Petroleum Gas Code) statewide through the State Fire Prevention Regulations. Tank setbacks, container sizing, and installation rules apply uniformly, with the Office of the State Fire Marshal as enforcement authority.
Under 16 Del. C. Chapter 66 and the Delaware State Fire Prevention Regulations (Part VI), Delaware adopts NFPA 58 for all liquefied petroleum gas storage and handling. Residential tanks above 125 gallons require Fire Marshal plan review. Setback distances depend on tank size: 125-500 gallon tanks need 10 feet from buildings and property lines; 501-2000 gallon tanks need 25 feet. Underground tanks have reduced setbacks. Installers must hold proper licensure. The state code applies uniformly statewide and supersedes inconsistent local rules, though municipalities may enforce zoning compatible with the fire code.
Improper installation, missing permits, or setback violations are misdemeanors under 16 Del. C. Section 6611, with fines up to $1,000 per violation and potential orders to remove or relocate non-compliant tanks.
