New York, Delaware County HVAC Permit Regulations and County Ordinances for Unincorporated Areas
HVAC Permit Requirements in Delaware County, New York
Delaware County, New York, does not maintain a centralized, county-wide building or safety department that issues HVAC permits. Building code enforcement, including the issuance of permits for HVAC, plumbing, and electrical work, is handled at the local municipal level (towns, villages, or cities).
Permit Rules for Unincorporated Areas
Properties located in unincorporated areas of Delaware County are subject to the building codes and permit requirements of the specific town in which they are situated. Because there is no county-level building department, you must contact the Code Enforcement Officer or Building Inspector for your specific town to determine if a permit is required for your HVAC project. Generally, under the New York State Uniform Fire Prevention and Building Code, permits are required for the installation, replacement, or modification of heating and cooling equipment. Always verify the specific requirements and application process with your local municipal office before beginning any work.

State Statutes and Codes Adopted
New York State regulates building construction, including HVAC systems, through the New York State Uniform Fire Prevention and Building Code (Uniform Code) and the State Energy Conservation Construction Code (Energy Code). These codes are contained within Title 19 of the New York Codes, Rules and Regulations (19 NYCRR). The state periodically updates these codes by adopting and incorporating by reference the latest model codes published by the International Code Council (ICC), along with specific New York State amendments.
As of the most recent update effective December 31, 2025, the state has adopted the 2025 editions of the New York State Uniform Code subunits, which include the Mechanical Code of New York State, the Residential Code of New York State, and the Fuel Gas Code of New York State. Additionally, the 2025 Energy Conservation Construction Code of New York State (ECCCNYS) is in effect, which aligns with state legislation such as the All-Electric Buildings Act, mandating specific electrification requirements for new construction.
Primary State Board and Agencies
The statutory responsibility for developing, maintaining, and updating the Uniform Code and the Energy Code is vested in the State Fire Prevention and Building Code Council (Code Council). The Code Council is a 19-member body appointed by the Governor, representing various stakeholders including architects, engineers, builders, trade unions, and local government officials.
The New York State Department of State (DOS), specifically its Division of Building Standards and Codes, provides the administrative support, technical guidance, and enforcement oversight for these codes. The Division acts as the secretariat to the Code Council and manages the rulemaking process for code updates.
