NYC DOB HVAC Permits & MEP Filing, Handled End to End

What NYC DOB Mechanical Permitting & MEP Filing Actually Requires

In New York City, most commercial HVAC and mechanical work — new system installs, rooftop unit and boiler changeouts, ductwork, refrigeration, cooling towers, and associated piping and supports — must be filed with the Department of Buildings (DOB) before work begins. Filings are submitted under the Mechanical Systems (MS) work type in the DOB NOW: Build portal. A New York State licensed Professional Engineer (PE) or Registered Architect (RA) must prepare and submit the construction documents, which have to demonstrate compliance with the NYC Building Code, the Zoning Resolution, and the NYC Energy Conservation Code. The actual work permit is issued to a licensed/registered contractor who performs the installation. Depending on the scope, the project may also trigger Building Code Chapter 17 special inspections (filed via a TR1 Statement of Responsibility) and a mandatory energy code progress inspection, both of which must be completed and closed out in DOB NOW before the project can be signed off. HVAC is central to all of this because the equipment, its energy performance, and its supports are exactly what the DOB is reviewing and inspecting. This page applies to building owners, property managers, and facilities directors who are installing or replacing commercial HVAC equipment and need it filed, permitted, inspected, and documented correctly. Note that certain minor mechanical work may be permit-exempt under the DOB's rules — Com+ can confirm whether your specific job needs a filing.
