HVAC Permit in New York City, New York

Frequently asked questions

Do you need an HVAC permit in New York City?

1 RCNY 101-14 Table 1 exempts a packaged air-conditioning unit of 5 tons rated capacity or less installed in an existing one- or two-family dwelling, including window and existing under-window sleeve installations, so long as it is not part of an alteration that otherwise requires a permit. Table 2 sets the same exemption at 3 tons for all other buildings, and separately exempts a voluntary air conditioning and ventilating system serving only one floor if it uses no lot line openings, is not in a public hallway, passageway or stairway, does not reduce required ventilation, and does not penetrate any fire division, roof, floor or wall. Everything beyond that is a Mechanical System alteration for which a Registered Design Professional must submit construction plans before a permit issues. Any electrical work for the equipment needs a separate electrical permit filed by a NYC licensed electrical contractor, and replacing a gas water heater, gas furnace or gas-fired boiler of 350,000 BTU or less in a building of five families or fewer falls under ordinary plumbing work done by a Licensed Master Plumber.

Can a homeowner pull an HVAC permit themselves in New York City?

Under New York law (Inside New York City: NYC Admin. Code 28-104.1, 28-105.1, 28-105.4, 28-105.5.1, 28-401.3 (definition of "general contractor"). Outside New York City: N.Y. Exec. Law 381(2); 19 NYCRR 1203.3(a)(1).): New York State sets no owner-builder rule at all outside New York City. Executive Law 381(2) puts administration and enforcement in the hands of each local government, and 19 NYCRR 1203.3(a)(1) only requires each authority having jurisdiction to make building permits mandatory for work that must conform to the codes, leaving who may apply to local law. The state licenses no general contractors and imposes no owner-builder affidavit, disclosure form or post-permit sale restriction of the kind Florida uses, so whether a homeowner may pull the permit is a question for the specific city, town, village or county. New York City is the genuine outlier. Administrative Code 28-105.1 makes the work itself unlawful without a written permit, and Administrative Code 28-104.1 bars the department from issuing that permit until it approves the required construction documents, which must be prepared by or under the supervision of a registered design professional, meaning a licensed architect or engineer, as required by the code. A homeowner therefore cannot self-prepare and file the plans for permit-requiring work in New York City even though Administrative Code 28-105.5.1 defines the permit applicant as the person who performs the work or retains a subcontractor, and even though the general contractor registration definition in Administrative Code 28-401.3 expressly excludes an individual who constructs a residential structure of no more than three dwelling units for his or her own occupancy. Note that Administrative Code 28-105.4 exempts minor alterations and ordinary repairs from the permit requirement entirely, so the design professional bottleneck applies only to work that needs a permit in the first place.
