New York City Site Safety Training (SST) requirements apply to many workers and designated site-safety professionalson construction sites covered by NYC DOB rules. The correct training path depends on your role, your existing training, whether you need a new card or a renewal, and current DOB requirements.
How many SST hours do workers need?
NYC DOB states that workers on covered jobsites generally need an SST card showing at least 40 hours of approved safety training. Designated site-safety supervisors generally need a 62-hour Supervisor SST card.
For new SST card issuance, NYC DOB now requires the 2-Hour Mental Health Awareness course. It replaced the former 2-Hour Drug and Alcohol Awareness course after August 1, 2026. DOB also states that, effective May 3, 2026, the 40-Hour Site Safety course may be treated as equivalent to OSHA 30 for SST credit where applicable.
If you need a complete worker pathway rather than individual courses, review Tribune’s 40-Hour Worker SST training page.
What about Supervisor SST?
Supervisor SST is intended for designated site-safety professionals and requires a broader training pathway. Tribune maintains dedicated pages for Supervisor SST training, the 62-Hour Supervisor SST pathway, and the 32-Hour Supervisor SST option.
How long is an SST card valid?
NYC DOB currently states that SST cards are valid for five years. Under Local Law 10 of 2026, cards expiring on or after May 3, 2026 have a one-year grace period to renew, but an expired card cannot be used on a jobsite during that grace period. Workers can review Tribune’s Worker SST renewal page, while supervisors can review Supervisor SST renewal.
What is the Worker Wallet?
The NYC DOB Worker Wallet is used for certain worker qualification cards, including scaffold-related credentials. DOB states that the Worker Wallet does not replace the SST card. Learn more in Tribune’s Worker Wallet guide.
Does mental health awareness count toward SST renewal?
NYC DOB updated selected renewal options effective August 1, 2026. The 2-Hour Mental Health Awareness course can be combined with either 2-Hour Tool Box Talks or 2-Hour Pre-Task Meeting within the affected renewal pathways. This does not mean the mental health course alone renews a card, and not every renewal option changed.
Compare your training records with the current DOB renewal table before choosing courses. Tribune has information for 2-Hour Mental Health Awareness, 2-Hour Toolbox Talks and 2-Hour Pre-Task Meeting.
What should I prepare when requesting an SST renewal?
- Your existing card and its expiration date.
- Course completion records, including the training dates.
- Whether your card is a worker or supervisor card.
- The renewal option you intend to complete and any missing courses.
Review Worker SST renewal or Supervisor SST renewal before registering. Bring your records so the correct pathway can be checked.
Where should I start?
