NYC Building Department Unveils New HVAC Permit Requirements for 2024: What Property Owners Need to Know
New York City’s building landscape continues to evolve with updated regulations designed to improve safety, energy efficiency, and compliance across all HVAC installations. The NYC Department of Buildings (DOB) has issued updated filing requirements for mechanical systems work, effective as of April 4, 2024, designed to streamline the process and ensure that all necessary permits are filed through DOB NOW: Build.
Key Changes in 2024 HVAC Permit Requirements
Any mechanical system work associated with new buildings or alterations must be filed under the “Mechanical Systems” (MS) work type in DOB NOW: Build. This significant update affects all heating, ventilation, air conditioning (HVAC), refrigeration, and cooling tower installations throughout the five boroughs.
One of the most impactful changes affects residential properties. Starting from May 12, 2020, whole-house ventilation systems became mandatory in all one- and two-family homes within NYC, following energy code standards outlined in the NYC Energy Conservation Code (NYCECC R403.6). This change eliminated previous exceptions, so all ventilation and air conditioning systems for these homes now require an MS work type filing in DOB NOW.
Understanding HVAC Permit Thresholds
Not all HVAC installations require permits, but understanding the thresholds is crucial for compliance. 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, if the mini-split system exceeds three tons or 36,000 BTU/hr, you are required to obtain a permit from the Department of Buildings.
For larger commercial installations, most air conditioning systems in NYC need an Equipment Use Permit, and only units that meet all the following conditions are exempt: A voluntary system that only provides air conditioning or ventilation in one floor, along with specific requirements regarding lot line openings, public spaces, and structural penetrations.
The DOB NOW: Build System
The transition to digital filing through DOB NOW: Build represents a significant modernization of NYC’s permit process. You can get required permits for the installation or alteration of heating, ventilation, or HVAC systems · To apply for a permit, you can electronically file through DOB NOW. This system streamlines applications and provides better tracking capabilities for both contractors and property owners.
Equipment Use Permits and Ongoing Compliance
Beyond initial installation permits, many HVAC systems require Equipment Use Permits (EUPs) for ongoing operation. New York City requires an Equipment Use Permit (EUP) for many devices. Equipment is inspected regularly to renew these permits, and the renewal interval depends on the type of equipment. The FDNY will schedule periodic inspections, and the building owner gets a Notice of Violation (NOV) if an EUP Card is missing. Even if you have an EUP Card, you can get a Notice of Violation for not posting it.
