Major Building Definition Update

Effective December 11, 2024, the NYC Department of Buildings (DOB) will revise the definition of a "major building" under Section 202 of Chapter 2 of the NYC Building Code.


The change lowers the height threshold for major buildings from 10 stories or 125 feet to 7 stories or 75 feet. This adjustment broadens the scope of buildings classified as "major," impacting compliance and safety protocols.


Additional criteria for major building status remain unchanged: structures with a footprint of 100,000 square feet or more, or those designated by the DOB Commissioner due to unique hazards, still qualify. The updated definition applies only to permits issued or requested on or after December 11, while existing permits and requests will not be affected.


This change is part of an ongoing effort to enhance safety standards across NYC's growing construction landscape.


The new definition of major building does not impact façade work. The site safety trigger for façade work will continue to apply only to buildings more than 14 stories or 200 feet in height.🀰
