We keep that walkthrough in one place: how an HVAC permit application and its inspections work, start to finish. What changes between New York jurisdictions is below: who requires a permit, what they charge, and which office you file with.

What an HVAC permit costs in New York
4 New York jurisdictions we cover publish a fee figure for this work. Each line is quoted from that office's own schedule and linked to its citation. The figures are not comparable to one another: some are flat minimums, some a percentage of job value, some charged per fixture, so what you pay depends on which schedule applies and on your job's valuation.
Heating permit application: $50.00 application fee, plus a $100.00 plan review fee if plans are required, plus a per-device permit fee. Published device fees include furnace, condensing unit or PTAC 0 to 140k BTU $100.00; packaged RTU or air heat pump 15 tons and less $125.00 and more than 15 tons $200.00; water sourced heat pumps 5 tons and less $100.00; boilers 500,000 BTU and less $100.00; boiler or burner replacement 500,000 to 1M BTU $150.00 and more than 1M $250.00; radiant heat, flooring or patio $100.00; fireplaces and gas inserts $95.00; radiant IR heating $95.00.

Town Code 86-11I(2), as adopted by Local Law No. 93-2022 (adopted 12-6-2022, effective 12-22-2022) and not changed by the 2024 amendment: $300 for an estimated cost of up to $1,000, plus $15 for each additional $1,000 or part thereof of estimated cost, with no separate fee where the system is part of a new building or an alteration for which a permit has already been issued. Where the work is heating rather than cooling, a separate plumbing permit filed by a Town licensed master plumber also applies.
