In a sweeping update to New York City’s construction regulations, the Department of Buildings (DOB) has redefined what constitutes a “major building,” significantly expanding the scope of projects that require licensed safety professionals. These changes, enacted under Local Laws 147 and 149 of 2021, that took full effect on December 11, 2024, and are already reshaping the landscape for developers, contractors, and safety managers across the five boroughs.
What Changed?
Previously, a “major building” was defined as any structure 10 stories or 125 feet and above. Under the new law, that threshold has been lowered to 7 stories or 75 feet. Additionally, any building with a footprint of 100,000 square feet or more, or one that undergoes vertical or horizontal expansion to meet these criteria, now falls under the “major building” category.

This reclassification means that thousands of new construction sites across NYC will now require the presence of DOB-licensed Site Safety Managers (SSMs) or Site Safety Coordinators (SSCs). These professionals are responsible for ensuring compliance with Chapter 33 of the NYC Building Code, which governs safety during construction and demolition.
The Role of Site Safety Supervisors
Site Safety Managers and Coordinators are not just figureheads—they are the frontline defense against construction hazards. Their responsibilities include:
- Developing and maintaining site safety plans.
- Conducting daily inspections and audits.
- Ensuring compliance with OSHA and DOB regulations.
- Coordinating with emergency services and DOB inspectors.
- Overseeing high-risk activities such as crane operations, scaffolding, and hot work.
The DOB mandates that these professionals be certified and licensed, and that they complete a 40-hour Site Safety Training course as part of their qualification process. [Source: rules.city…newyork.us]
Construction Superintendents: New Limits and Duties
In addition to SSMs and SSCs, Construction Superintendents are now required to be present full-time on major building sites. Under Local Law 149, the DOB has imposed new limits on how many jobs a superintendent can oversee:
- As of January 1, 2024, a superintendent may be designated for no more than three jobs.
- By January 1, 2026, that number drops to one job per superintendent.
This change ensures that superintendents are fully dedicated to the safety and management of their assigned sites. They must also maintain detailed logs of inspections, correct unsafe conditions, and coordinate with other safety personnel. [Source: rules.city…newyork.us]
Training Requirements: 40-Hour Site Safety Course
To become a licensed Site Safety Manager or Construction Superintendent, individuals must complete a 40-hour Site Safety Training course. This course is distinct from the 40-hour SST Worker Card and includes:
- OSHA 30-Hour Construction Safety
- 8-Hour Fall Prevention
- 4-Hour Supported Scaffold User
- 2-Hour Drug and Alcohol Awareness
- 2-Hour Site Safety Plans
- 2-Hour Toolbox Talks
- 2-Hour Pre-Task Safety Meetings
- General and Special Electives
Training must be completed through a DOB-approved provider, and the SST Supervisor Card must be obtained before applying for a license.
Why This Matters
The changes are part of NYC’s broader effort to improve construction safety following several high-profile accidents and fatalities. By lowering the threshold for major buildings and increasing oversight, the DOB aims to reduce risks and ensure safer work environments.
- More projects will require licensed safety professionals.
- Training and certification costs will increase.
- Project timelines may be affected by compliance requirements.
However, the long-term benefits—fewer accidents, reduced liability, and improved worker safety—far outweigh the initial challenges.
Enforcement and Compliance
The DOB has ramped up enforcement efforts, including:
- Random site inspections.
- Mandatory reporting of incidents.
- Civil penalties for non-compliance.
- Suspension or revocation of licenses for violations.
Site Safety Managers, Coordinators, and Superintendents must maintain daily logs, ensure proper signage, and report any unlicensed activity, especially involving cranes and telehandlers. [www.nyc.gov]
Resources and Support
To help professionals meet these new requirements, organizations like GBTS Training Academy offer comprehensive safety training programs in multiple formats—online, hybrid, and in-person. Courses are available in English and Spanish, and support is provided through phone, email, and the website.
