PTAC Installation Permits and Requirements: NYC Building Code Updates for 2024

Navigating NYC’s Complex PTAC Installation Permit Maze: Your 2024 Guide to Building Code Compliance

Installing a Packaged Terminal Air Conditioner (PTAC) in New York City isn’t as simple as mounting a window unit. With the 2022 Construction Codes effective on November 7 and the DOB periodically revising and updating the construction codes to ensure safe and compliant development, property owners and building managers must navigate an increasingly complex web of permit requirements to stay compliant with NYC building regulations.

Understanding PTAC Permit Requirements in NYC

The good news for basic installations is that a work permit or equipment use permit is generally not required to install a common window AC unit, unless the unit exceeds three tons/36,000 BTU/hr. However, PTAC units often fall into different categories due to their through-wall installation requirements and higher capacity ratings.

For larger installations, particularly in multifamily buildings, the permit landscape becomes more complex. A mechanical engineer working on a 5-story multifamily building project with 20 apartments proposing to install two (2) 1.5-ton PTAC units in each apartment would need to consider that the 2016 NYCECC Section C403.3 requires an economizer and the design may exceed the 300,000 BTU/h limit.

2024 Building Code Updates and Energy Compliance

One of the most significant changes affecting PTAC installations involves energy code compliance. The 2016 NYCECC requires economizers on all cooling systems, unless the indoor unit is less than 54,000 BTU/h, with all PTAC units at 18,000 BTU/h (or 1.5 tons) potentially exempt from an economizer, however there is a whole building limit on the capacity of cooling systems.

Property owners must also be aware that the 2025 Electrical Code is effective on December 21, 2025, with applications for electrical work filed on or after August 23, 2025, and associated with an existing building eligible to comply with the technical provisions of the 2025 NYC Electrical Code.

When Professional Installation Matters

While some PTAC installations may not require permits, the electrical work often does. Professional ptac installation services understand these nuances and ensure compliance with both mechanical and electrical codes. The complexity increases when dealing with older buildings where R-2 buildings have new window (PTAC) AC units installed in each apartment which replace old units, with PTAC name plates calling for MOP of 30 amps 208V and existing wiring from panel to PTAC receptacle in #12 THHN copper.

The DOB Application Process

For installations requiring permits, before any construction project begins in New York City, an application must be submitted for review by DOB to make sure the plans are in compliance with the Building Code, with the majority of construction requiring a Department of Buildings permit. The city has modernized this process, with DOB gradually moving from a paper-driven process to an electronic filing through DOB NOW, which will eventually contain all job applications.
