Furnace and Boiler Permits in Onondaga County, and Who Pulls Them
Your contractor pulls it, and whether one is needed is decided by your own city, town or village rather than by the state or by Onondaga County. Liverpool, Salina, Marcellus, Fayetteville, Cicero and the Town of Skaneateles all name heating equipment on their published permit lists. Camillus and Baldwinsville have adopted the state's optional exemption for replacing equipment, and that exemption turns on the equipment's listing rather than on your address.

Who does what on a permitted equipment replacement
You choose the contractor
You, before any paperwork existsAsk during the quote whether the permit is included, who files it and whether the fee is inside the price you were shown.
The application goes in
The contractor, at your city, town or village officeSeveral offices in this county want insurance certificates and a signed proposal with the application, and some want a survey. The requirements are published by each office.
The work is done
The installing contractorVillages including Skaneateles state that work shall not start until the Code Enforcement Officer has issued the permit.
The inspection closes it out
The code enforcement officer for that municipalityThis is the only independent look anybody takes at the install. Skaneateles village asks for at least 48 hours notice before an inspection is needed.
19 NYCRR 1203.3 requires every authority having jurisdiction to run a permit program; what it covers is set locally.
There is no New York State HVAC license, so the permit is your check
People ask us for a license number to look up, and for this trade in this state there usually is not one. The Department of State's Division of Building Standards and Codes states in its published FAQ that issues regarding local laws, zoning, and licensing of contractors or electricians are not handled by that division, and that in general every city, town, village and county is charged with administering and enforcing the Uniform Code and Energy Code within its jurisdiction. New York Business Express, the state's own portal for telling a business what it needs in order to operate, lists for a Heating, Ventilation and Air Conditioning Contractor only the federal requirement under Section 608 of the Clean Air Act, which covers technicians who work on stationary air conditioners and refrigeration systems and is what allows the purchase of refrigerant in bulk containers. It lists no state license for the trade at all. So what you can actually verify is local: insurance, the permit, and whatever your own municipality requires of the person filing it.
Inside the City of Syracuse the trade is licensed by the city itself
The city is the exception in this metro and it is a substantial one. Syracuse operates a Board of Mechanical Examiners which issues mechanical licenses in classes, and the classes describe the work. A Class A Master HVAC license entitles the holder to engage in the business of, and to secure permits for, installation, alteration, maintenance and repair of any heating, ventilating or air conditioning systems. Class B covers residential and medium sized commercial work up to stated equipment sizes, and Class C covers homes of not more than two families with air conditioning up to five tons, furnaces up to 200 MBH input and boilers up to 399 MBH. Earning one is not a formality: Class A requires a minimum of ten years experience, Class B and C a minimum of five, with one year defined as 2,000 hours, and a written examination passed at 70 percent. Examinations are held at the Division of Code Enforcement, 300 South State Street, 7th Floor, and the licensing telephone number on the application is (315) 448-8773. The city also publishes a List of HVAC Contractors by license class, though the copy we read is dated 2022, so treat it as a starting point and confirm with the office.
In the city, an HVAC permit is filed separately from everything else
This trips up homeowners doing a larger project, and it is simple once you know. The Central Permit Office lists residential construction permit categories covering additions and conversions, decks, driveways, fences, fenestration, interior remodels, new builds, pools, roofs, sheds and garages and the rest, and then states that all trade and fire prevention permits, giving HVAC, electrical, fire alarm and sprinkler as its examples, must be obtained separately. So a heating system replacement does not ride along inside a general building permit for a renovation. That office sits on the 1st floor of One Park Place, 300 South State Street. The practical version for a homeowner comparing bids: ask which permit is being pulled, by whom, and in which office, and if a contractor tells you a city job needs nothing, ask them to put that in writing next to the model number.
Camillus and Baldwinsville adopted the replacement exemption, and there is a catch in it
Two municipalities in this county have taken up an option the state offers, and the wording of it is the part that matters. 19 NYCRR 1203.3(a)(1) requires every authority having jurisdiction to require building permits for work that must conform to the Uniform Code or the Energy Code, and then allows, where expressly set out in the local program, exemption of listed categories. One of those categories is replacement of any equipment provided the replacement does not alter the equipment's listing or render it inconsistent with the equipment's original specifications. The Town of Camillus adopted that at section 26.30(B) of its Uniform Code Enforcement chapter, and the Village of Baldwinsville adopted it in a local law filed with the Department of State in June 2022. Read the condition again, because it is about the equipment and not about the address. Swapping an atmospherically vented furnace for a condensing furnace that vents out a side wall is not a like-for-like change in listing, and Oak Ridge National Laboratory's own description of that upgrade is that the existing vent cannot be used by the new furnace directly. Both local laws also restate that an exemption from the permit requirement is not an authorization for work to be performed in violation of the codes.
The towns and villages that name heating equipment outright
In much of this county there is no ambiguity at all, because the office has published the list. The Village of Liverpool names installation of any gas lines or appliance including space heaters, and installation of any new or replacement furnace, central air conditioning, boiler, gas fireplace or other heating equipment, and publishes separate HVAC, mechanical and heating appliance and chimney applications. The Town of Salina includes additions or new heating systems, solid fuel heating devices or gas inserts on its permit list, filed at the Department of Planning and Development. The Town of Marcellus names furnace installation on its project list and publishes a Heating Appliance Chimney Permit Application, at 22 East Main Street on 315-673-3269. The Village of Fayetteville lists installing or replacing a heating unit, fireplace, woodstove or other solid fuel burning device or chimney and vents, and wants notarized signatures on the application. The Town of Cicero requires one to install or replace any fireplace, woodstove or other solid fuel burning device, chimney, vents or heat producing devices, on 315-752-1180 extension 504. The Town of Skaneateles publishes a permit application headed Heat Producing Appliances, dated 2024.
Where the published list says nothing about heating, which is not the same as no
Silence on a web page is not an exemption, and this is where homeowners get caught assuming. The Village of Solvay publishes examples of projects requiring a building permit covering new buildings, additions, remodeling, pools, sheds, fences, decks, demolition and fireplaces and woodstoves, and furnaces, boilers and air conditioning are simply not named on it, so the village asks anyone unsure to call Code Enforcement on (315) 468-1679. The Town of Clay names building permits as a service area but publishes no schedule of the work that requires one, giving codes@townofclayny.gov and (315) 652-3800 extension 172 instead. The Town of DeWitt takes the broad approach, stating that with the exception of minor repairs a permit is needed to upgrade, modify or install any fixed or movable improvements to real property, with a signed estimate and a current survey required in the application. The Village of East Syracuse enforces the full code set including the Mechanical and Fuel Gas Codes from 204 North Center Street on 315-437-3541, and the Town of Manlius publishes the 2020 code set it enforces and takes applications online. In every one of those cases the answer is a phone call, not an inference.
North Syracuse, and why we send you to the village rather than the town
We owe you an admission on this one. We could not retrieve the Village of North Syracuse code enforcement page over a secure connection on the date we checked, the server failed the handshake at every address we tried, and we do not publish a source we cannot link. So there is no permit detail for the village on this site. What we can tell you is which office answers for the address, and that comes from the state: the Department of State states that in general every city, town, village and county administers and enforces the Uniform Code within its jurisdiction, which makes the village itself, rather than the surrounding towns of Cicero or Clay, the place a North Syracuse homeowner asks. If a contractor tells you a village address is handled by the town, that is worth checking before the work starts rather than afterwards.
What Skaneateles village wants in the envelope, and what that tells you about a bidder
One village in this county publishes exactly what an application has to contain, and the list doubles as a contractor screening tool anywhere. The Village of Skaneateles requires every application to include a current copy of the contractor's or homeowner's liability insurance and a current Workers Compensation Insurance Certificate or Exemption Certificate, citing section 125 of the General Municipal Law, plus a detailed copy of the job proposal or contract signed by the property owner including an accurate project cost. It states that work shall not start until the Code Enforcement Officer has issued a building permit, and that the officer must be given at least 48 hours notice before any inspection. The office is at 26 Fennell Street on 315-685-2118. Notice what that means in practice: a bidder who cannot produce a workers compensation certificate cannot be permitted in that village, whatever they say about price. Asking any contractor for those two documents early costs you nothing and answers a question you would otherwise be taking on trust.
Baldwinsville has adopted a stretch energy code, so ask the village what applies
One more Baldwinsville item, and we are flagging our own uncertainty on it deliberately. Local Law No. 7 of 2022 adopts, as the village's local energy conservation construction code, the State Energy Code modified in the manner contemplated by NYStretch Energy Code 2020 version 1.0, published by NYSERDA, applying to buildings constructed, substantially renovated or altered in the village on or after the law's effective date, with one carve out for a section that NYStretch would otherwise have added. The law's own section 3 makes enforceability contingent on a filing with the Department of State and a determination by the Code Council, and we have not verified the current enforcement status of that filing. So the accurate statement is that Baldwinsville has adopted a stretch energy code and the village code office is the place to confirm what it requires of a mechanical project today. It is a short call and it is better made before a contract is signed than after an inspection.
What the permit is buying you that the cheapest bid is not
Two things, and neither is the piece of paper. The first is the inspection, which is the only independent look anyone takes at work that will sit behind a cabinet or above a ceiling for the next twenty years, and which you cannot buy separately at any price. The second is a filter on who can bid, because a permit requires credentials and insurance that the cheapest number on your table may not have. There is a third benefit that is easy to miss: the energy code carries the equipment sizing requirement, so a job running through the permit process is a job where somebody official has reason to ask how the size was arrived at, which is the subject of our sizing guide. What nobody here can do is tell you whether your specific job at your specific address needs a permit. That determination belongs to your code official, the offices and numbers above are published by the municipalities themselves, and the call is short. When you are ready for quotes from contractors who file the paperwork as a matter of course, send us the address and the equipment you are replacing.

19 NYCRR 1203.3(a)(1) requires every authority having jurisdiction to include in its code enforcement program provisions requiring building permits for work that must conform to the Uniform Code or the Energy Code. It then allows, where expressly set forth in the local program, exemption of listed categories of work. Three of those categories touch heating and cooling work: item (vi), installation of listed portable electrical, plumbing, heating, ventilation or cooling equipment or appliances; item (vii), replacement of any equipment provided the replacement does not alter the equipment's listing or render it inconsistent with the equipment's original specifications; and item (viii), repairs, provided the work does not affect any part of the structural system, the required means of egress, or the fire protection system. The regulation adds that an exemption from the requirement to obtain a building permit is not an authorization for work to be performed in violation of the Codes.

Oak Ridge National Laboratory states that in every upgrade of this kind the existing Category I noncondensing furnace is served by a negative static pressure vent, for example a clay tile lined masonry chimney or a Type B double-wall metal chimney terminating above the roof, and that this existing vent cannot be used by the Category IV condensing furnace directly. It describes the options as reusing the existing vertical vent as a chase for the new venting system, installing a new horizontal side-wall vent system where physical constraints and codes allow, or running a new vertical vent through the building, which it calls difficult and costly. It states that in all of these cases there are added costs compared with a like-for-like noncondensing furnace replacement.
