NYC DOB and Local Law 97 require ongoing HVAC maintenance for buildings over 25,000 sq ft. Boiler inspection is annual under DOB §28-303. Refrigerant log retention is required under EPA Section 608 for systems over 50 lbs charge. LL97 emissions reporting starts in the 2024 to 2029 compliance period, with caps roughly 40 percent stricter in 2030 to 2034. Restaurant kitchen exhaust and fire damper inspections add FDNY and DOH requirements. This page is a code reference for NYC building owners and managers, not a marketing pitch.
The code sections every NYC building owner and property manager should know. References to the NYC Administrative Code, Mechanical Code, and Local Law 97 directly.
Annual inspection required for any boiler over 350,000 BTU/hr by a licensed boiler inspector. Certificate of inspection retained on-site for 3 years. DOB issues the boiler permit and tracks the inspection schedule by BIN.
Annual greenhouse gas emissions report filed with the NYC Mayor's Office of Climate and Environmental Justice. 2024 to 2029 caps are soft; 2030 to 2034 are roughly 40 percent stricter. Penalty of $268 per metric ton of CO2e over the cap. Ongoing maintenance with documented refrigerant logs and efficiency tracking is how a building stays compliant.
Federal regulation requiring logged refrigerant additions, recoveries, and equipment changes on systems over 50 lbs charge. NYC DOH adds state-level documentation for commercial refrigeration over 200 lbs charge. Records retained 3 years on-site; longer for commercial refrigeration. Technician must hold EPA Section 608 certification card.
Fire dampers inspected every 4 years for non-hospitality buildings, every 6 years for hospitality. Inspection certificate retained 5 years on-site. The inspection is typically combined with annual HVAC maintenance visits to avoid separate access events.
Grease ductwork cleaning every 3 to 12 months based on cooking volume. Quarterly is the standard for moderate-volume restaurants; monthly for high-volume kitchens. Cleaning logs retained 3 years on-site. Closure order possible for missed cycles plus FDNY violation.
All cooling towers must be registered with the NYC DOH within 30 days of installation. Quarterly water sampling for Legionella, annual maintenance plan filed, and operational logs retained 3 years on-site. Applicable to any building with an evaporative cooling tower.
Maintenance requirements scale with building size and use. Below: the typical compliance profile by building class.
Owner-driven maintenance only. No NYC-mandated annual inspection unless the home has a boiler over 350,000 BTU/hr (rare residential). Vinco's residential maintenance contract is a quality-of-service offering, not a code requirement.
Annual boiler inspection if applicable. Refrigerant logs on any system over 50 lbs charge. Not subject to LL97 emissions caps but still subject to general DOB and FDNY requirements.
All of the above plus LL97 covered: annual emissions report, refrigerant log retention 3+ years, periodic fire damper inspection. Quarterly preventive maintenance is industry practice to keep emissions reports audit-ready.
Full compliance stack: annual boiler, LL97 emissions report with engineer letter, quarterly preventive HVAC, refrigerant logs, cooling tower registration (if present), fire damper cycle, and BMS-integrated efficiency tracking. Most owners contract building-wide maintenance to a single licensed contractor.
All commercial requirements above plus FDNY restaurant kitchen exhaust cycles (every 3 to 12 months), DOH grease-trap log, refrigeration log under DOH for any walk-in cooler or freezer, and additional fire damper cycles per Mechanical Code hospitality schedule.
