Onondaga County
New Heating and Cooling Systems in Clay, NY
Clay is the one town here where the permit question cannot be answered from a website: the Department of Codes names building permits as a service area but publishes no schedule of the work that needs one, so the phone call comes first. It is also the largest housing stock in the county, 26,282 units, and one of its newest.

Clay publishes the code office number, not the permit list
The Town of Clay Department of Codes publishes its commissioner, an email address at codes@townofclayny.gov and a telephone number of (315) 652-3800 extension 172, but not a list of the work a permit covers. So in Clay the reliable route is to ask the office directly what your job needs before anything is ordered, and to have the contractor confirm in writing who is pulling the permit if one applies. The housing here argues for asking early: barely three percent of Clay predates 1940, which means most of the town is on its first or second system rather than its fourth, and the venting arrangements are newer and more varied than in the old villages. Clay also carries 832 homes on bottled, tank or LP gas, one of the highest counts in the county, and a propane house comparing a new furnace against a heat pump is comparing different numbers from a gas main house two miles down the road. Liverpool village sits inside this area on the map but is its own government with its own permit list, so check which side of the line the address falls.
