New York City code update changes definition of a major building

Changes affecting how construction projects in New York City are permitted will have significant impacts for contractors.

On Dec. 11, the definition of a major building in the city’s code will change from 10 stories to seven, or 75 feet. The change will affect thousands more projects.

It will require a site safety coordinator and an approved site safety plan for any major new build, full demolition, or interior demolition with mechanical equipment that is seven stories or higher. Contractors working on these major projects should hire professionals to assist them with navigating through the entire application, permit, certificate of occupancy, approval, and sign-off processes, advises a former New York Department of Buildings assistant commissioner. Contractors who have previously built only low-rise buildings should also hire a safety consultant to provide full-time safety professionals and obtain approvals for site safety plans and tenant protection plans, he says.

The code change includes a provision for construction superintendents to only be designated on three permits at one time. In January 2026, this number will be reduced to one permit. As a result, contractors should send their staff to obtain superintendent licenses and Supervisory SST training cards.

New York City has two very large buildings dedicated to answering the 911 calls of its five boroughs. With more than 11 million emergency calls annually, it makes perfect sense. The second of these buildings, the Public Safety Answering Center II (PSAC II) is located on a nine-acre parcel of land in the Bronx. It’s an imposing 450,000 square-foot structure—a 240-foot-wide by 240-foot-tall cube. The gleaming aluminum cube risesthe equivalent of 24 stories from behind a grassy berm, projecting the unlikely impression that it might actually be floating. Like most visually striking structures, the building has drawn as much scorn as it has admiration.
