Getting a straight answer in Clay before you order
The housing is a reason to ask early rather than late. Clay has 26,282 housing units, the largest count of any municipality in the county, and only 831 of them predate 1940, so most of the town is on its first or second system rather than its fourth. That means the venting arrangements are newer and far more varied than in the old villages: sidewall vents, Type B through the roof and masonry chimneys all exist here within a few streets of each other. A quote that has not looked at what is actually there has not established what the new appliance will need, and in a town with no published list the paperwork question depends on what the work turns out to be.
Call the codes office first
Extension 172 on (315) 652-3800, or codes@townofclayny.gov. The town publishes the contact rather than the rule, so the contact is the rule.
Get the permit responsibility in writing
Who applies, when, and what happens to your start date if it is needed. A contractor who works in Clay will have had this conversation before.
Establish what is venting the current appliance
In a town where only 3.2 percent of the housing predates 1940, the existing vent could be almost anything, and it decides what the replacement needs.
What 26,282 homes and no published permit list mean together
The Town of Clay Department of Codes page names building permits as one of its service areas but does not publish a schedule of the work that requires one. It gives the commissioner as Joseph Grispino, an email address of codes@townofclayny.gov and a telephone number of (315) 652-3800 extension 172.

The American Community Survey 2020-2024 five-year estimates put the median year structure built in the town of Clay at 1978, plus or minus 1 year. Of 26,282 housing units, the largest count of any municipality in the county, only 831 were built in 1939 or earlier, 3.2 percent, 14,459 before 1980, 55.0 percent, and 4,053, 15.4 percent, in 2000 or later. Of 25,725 occupied units, 17,654 are heated with utility gas, 68.6 percent, 6,334 with electricity, 24.6 percent, and 832 with bottled, tank or LP gas, 3.2 percent. 18,316 units, 71.2 percent, are owner occupied.

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 Town of Clay publishes, and what it does not
The Town of Clay Department of Codes names building permits among its service areas and publishes its commissioner, an email address at codes@townofclayny.gov and a telephone number of (315) 652-3800 extension 172. What it does not publish is a schedule of the work that needs one. So in Clay the reliable route is the reverse of everywhere else: ask the office directly what your furnace job requires before anything is ordered, and have the contractor confirm in writing who is pulling the permit if one applies. It takes five minutes, and it is the only way to get a Clay answer rather than an assumption borrowed from Liverpool or Cicero next door.
One call to the codes office, before the order
Send the Clay address and we will make sure that question is asked in the right order.
Clay furnace and paperwork questions
How do I find out whether my job needs a permit in Clay?
Ask the Department of Codes. It publishes an email address and a telephone extension but no list of the work a permit covers, so no website can tell you, including this one. What we will not do is guess on your behalf, because a wrong answer about a permit is worse than no answer.
Liverpool is on my mailing address. Does its permit list apply?
Only if your property is inside the village line. Liverpool village sits within this area on the map but is a separate government with its own published list of work requiring a permit. Check which side of the line the address falls on before anyone fills in a form.
Tell us what is venting your current furnace
Chimney, Type B or a sidewall pipe. In Clay it could be any of the three and it changes the job.
