When developing or renovating a building in New York City, project owners and developers must comply with stringent NYC Department of Buildings (DOB) codes. One critical—but often overlooked—requirement is the Special Inspection of Mechanical Systems.
These inspections are not optional. They’re mandated under the NYC Building Code (Chapter 17) and must be performed by a certified Special Inspection Agency approved by DOB.
At Alan Margolin & Associates, we are fully accredited to perform “Mechanical Systems” Special Inspection in NYC. Our engineers and inspectors ensure your systems are installed to code, function safely, and meet energy and performance standards.
What Falls Under Mechanical Systems Special Inspection?
According to the NYC Building Code, Special Inspection of Mechanical Systems generally includes:
- Heating, Ventilation, and Air Conditioning (HVAC) installations
- Smoke control systems and mechanical exhaust
- Duct leakage testing and fire/smoke damper inspections
- Energy code compliance for mechanical systems
- Refrigerant systems testing
- Kitchen exhaust and grease duct systems
- Mechanical pressurization for egress systems (e.g., stairwell pressurization)
Proper documentation, testing, and DOB coordination are essential. In many cases, failure to perform special inspections at required milestones can delay your Certificate of Occupancy or Temporary Certificate of Occupancy (TCO).
