Furnace Replacement in Camillus and the Listing Question
In Camillus the paperwork does not turn on your address, it turns on whether the new furnace keeps the listing and specifications of the old one.

Settling the listing question before you agree the job
Two things follow, and neither is paperwork for its own sake. The chapter states that the exemption is not an authorization to perform work in violation of the Uniform Code or the Energy Code, so it changes who checks the job rather than the standard the job has to meet. And it decides whether an independent inspector ever sees the installation, which is the only outside look most homeowners get. The other Camillus question is village or town: 32.2 percent of the village's housing was built in 1939 or earlier against 6.1 percent of the town's, so two houses with the same mailing address can be five decades and two completely different vent arrangements apart.
Ask whether the listing changes
The exemption covers replacement that does not alter the equipment's listing or depart from its original specifications. Atmospheric to condensing is the case to ask about.
The exemption is about paperwork, not standards
Chapter 26 says in terms that it is not an authorization to perform work in violation of the Uniform Code or the Energy Code.
Village or town, and they are not alike
32.2 percent of the village predates 1940 against 6.1 percent of the town, which is a different house and a different flue.
How Camillus adopted the exemption, and what its two housing profiles look like

The Town of Camillus Chapter 26, Uniform Code Enforcement, revised 4/14/2026, states at section 26.30(A) that a building permit is required for any work which must conform to the Uniform Code or Energy Code, including the construction, enlargement, alteration, improvement, removal, relocation or demolition of any building or structure, and the installation of a solid fuel burning heating appliance, chimney, or flue in any dwelling unit. Section 26.30(B) then adopts the optional exemptions, including item 5, installation of listed portable electrical, plumbing, heating, ventilation or cooling equipment or appliances, and item 6, replacement of any equipment provided the replacement does not alter the equipment's listing or render it inconsistent with the equipment's original specifications. Section 26.30(C) states that the exemption is not an authorization for work to be performed in violation of the Uniform Code or the Energy Code.

The American Community Survey 2020-2024 five-year estimates put the median year structure built in the town of Camillus at 1966, plus or minus 1 year, and in Camillus village at 1958, plus or minus 7 years. The two differ sharply on age: 6.1 percent of the town's 11,481 housing units were built in 1939 or earlier, against 32.2 percent of the village's 771 units. 69.1 percent of the town predates 1980, against 78.5 percent of the village.

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.

What furnace replacement involves


What the Camillus replacement exemption actually turns on
Chapter 26 of the Town of Camillus code, revised in April 2026, requires a building permit for work that must conform to the Uniform Code or the Energy Code, and then adopts the optional exemptions, among them replacement of any equipment provided the replacement does not alter the equipment's listing or render it inconsistent with the original specifications. Read that wording next to a modern furnace quote and the question becomes concrete. A sealed combustion condensing appliance is a different category of equipment from the atmospheric furnace it replaces, with a different vent system, so whether your job sits inside that exemption is a question for the town rather than an assumption for the contractor.

Camillus furnace and exemption questions
So do I need a permit or not?
That depends on what is being installed, and it is the town's call rather than ours. The exemption Camillus adopted covers replacement of equipment that does not alter the listing or depart from the original specifications, and a change from an atmospheric appliance to a sealed combustion condensing one is precisely the case to put to the codes office before anything is ordered.
If no permit is needed, does the work still have to meet the standard?
Yes, and the chapter says so. It states that the exemption is not an authorization to perform work in violation of the Uniform Code or the Energy Code. What changes is whether an independent inspector attends, which is a reason to be more careful about who you hire rather than less.
