Full Breakdown

G.L. c. 148 Sections 9 and 13 require a license from the local licensing authority with state fire marshal approval to keep, store, manufacture, or sell more than specified quantities of flammable liquids and gases including LP-gas. Residential propane tanks under 41 pounds water capacity are generally exempt, but larger installations require permits and must comply with 527 CMR 1.00 (Massachusetts Comprehensive Fire Safety Code), which adopts NFPA 58 with state amendments uniformly across all municipalities.

Violations & Penalties

Unlicensed storage or installation violates state fire code and exposes operators to fines and tank removal orders by the fire marshal.

Frequently Asked Questions

Do I need a permit for a backyard grill propane tank?
No. Standard 20-pound grill cylinders fall below the licensing threshold under c. 148. Larger residential tanks (typically 100 gallons or more) require permits.
Who installs propane tanks legally?
Only state-licensed propane installers may install permanent tanks. The local fire chief must inspect and approve installations under 527 CMR 1.00.
