Full Breakdown
Boston splits fire-suppression fees into two distinct charges. Installing, altering, or repairing a sprinkler system or other fire-extinguishing apparatus requires a permit application to the Commissioner of Inspectional Services under Section 105 of the state Building Code, 780 CMR, billed at a primary fee of $20 plus $1 for each sprinkler head, hose, or chemical extinguishing outlet involved. 5 of Article 12, Chapter 11 of the 1969 Ordinances (the Boston Building Code), 'as amended,' rather than in the state minimum. That means a building's sprinkler system in Boston isn't just installed once and left alone; it must be retested every year, with the fee scaling by the number of heads, hoses, and outlets the same way the installation fee does.
Neither fee provision sets the underlying threshold for which buildings must have sprinklers in the first place, that trigger comes from the state Building Code, 780 CMR, but Boston's own ordinance is what obligates the annual re-inspection once a system exists.
Violations & Fines
Neither subsection prints a standalone fine. Skipping the required annual test leaves a building's fire-suppression system out of compliance with Section 1204.5 of Article 12, Chapter 11 of the Boston Building Code (1969, as amended), the local retest mandate, giving the Inspectional Services Department grounds to withhold certification until the inspection fee is paid and the test is performed.
