Full Breakdown
Boston runs two distinct permits for propane. Installing a liquefied petroleum gas supply, the standard case for a homeowner adding an LP tank, requires an application under Section 105 of the state Building Code, 780 CMR 105, billed at a primary fee of $20 plus an additional $5 for each 100 pounds of gas or fraction thereof to be stored. 50 for each heating apparatus or appliance involved, rather than the per-100-pound formula. The same fee section also covers permanent gasfitting work more broadly: installing, altering, or repairing permanent gasfitting in new construction costs a primary fee of $20 plus $5 for each appliance or meter installed, altered, or substantially repaired.
L. Chapter 148, Section 10A, priced at $150 per installation or connection, a materially higher cost than the storage-only permits, reflecting that it covers the physical equipment hookup rather than just holding the fuel on site.
Violations & Fines
The fee ordinance sets no separate penalty of its own; storing or supplying propane without the required permit means the installation was never authorized under Section 105 of the state Building Code, leaving the Building Commissioner and Inspectional Services free to withhold occupancy or utility sign-off until the correct permit is obtained and its fee paid.
