The 5 Certifications You Need to Work in Construction in NYC — And Where to Get Them All

Every week, workers arrive at NYC construction sites with incomplete training or unrecognized certs and get sent home before they even start. This can happen to both new and experienced workers, often because no one told them exactly what NYC requires. If this has happened to you or you want to ensure it never does, you are in the right place.

To work on most New York City construction sites, you need five specific certifications. Many workers mistakenly believe OSHA 30 alone is sufficient. Below, learn exactly what is required — plus the fastest way to get everything sorted in Brooklyn.

Why OSHA 30 Alone Is Not Enough to Work on NYC Construction Sites

No doubt, OSHA 30 is a solid certification every construction worker must have, but in New York, you need more than that. New York City's Local Law 196 requires every worker on NYC construction sites to complete at least 40 hours of DOB-approved SST. OSHA 30 offers you only 30 hours of the training requirements, while the remaining 10 must be completed through a DOB-approved provider before you can legally be on site.

Beyond the SST requirement, certain tasks on NYC sites have their own certification requirements. For instance, working on a supported scaffold, directing traffic in a construction zone, and handling materials that generate silica dust each require certifications that you must possess. Having your OSHA 30 and SST card does not automatically clear you for those tasks.

What Certifications Do You Need to Work in Construction in NYC?

The five certifications below cover what most NYC construction sites require before you can work legally. Some are required under Local Law 196, some under separate NYC or OSHA rules, and others apply only to specific on-site tasks. Knowing which ones you need before you show up is what keeps you working.

1. OSHA 30

OSHA 30 is where everything begins. It is a 30-hour course that covers the hazards that cause most injuries and fatalities at NYC sites, including fall protection, scaffolding safety, electrical hazards, and proper use of PPE. Under Local Law 196, it is required for supervisors and foremen, but most general contractors across Brooklyn and the five boroughs expect every worker on site to have it, not just the people in charge.

Most new workers do not realize OSHA 30 counts as 30 of the 40 hours needed for the NYC SST card. That makes it the smartest cert to get first. Once you have it, you only need 10 more hours of DOB-approved training for a full SST card.

However, if your training completion program is not DOB-approved, those 30 hours are not worth anything and do not count toward your SST card in New York City.

2. SST 10-Hour Package

Once you have your OSHA 30, the SST 10-Hour Package completes your full NYC SST card. The package covers 8 hours of fall prevention (SST-307) and 2 hours of drug and alcohol awareness (SST-302). Combining this with the OSHA 30 meets the full 40-hour requirement under Local Law 196.

Your SST card is valid for five years, and your OSHA 30 must also be issued within that timeframe for the SST 10 to count. If it has expired, you must complete the full 40-hour package instead of just the 10-hour top-up. Renewal requires 8 hours of refresher training before expiration. Once it lapses, you cannot renew or use it on NYC construction sites.

3. 4-Hour Scaffold User

New York City has had its scaffold rules long before Local Law 196. Under Local Law 52, any worker on a supported scaffold needs 4 hours of DOB-approved training to be on that scaffold legally. And your years of experience do not change that requirement.

The course covers scaffold types, load limits, fall protection, and hazard recognition, as well as New York's building code requirements that apply specifically to scaffold work across the five boroughs. A 4-Hour Scaffold User certificate is valid for only four years.

As of July 1, 2025, the DOB Worker Wallet is the only accepted scaffold credential on NYC job sites. If your scaffold card was issued before November 1, 2024, and you have not converted it, you cannot work on a scaffold site at this time. Workers who complete this course through Fast Track get their credential in the correct Worker Wallet format from day one, with no separate conversion step needed.

4. 4-Hour Flagger

New York City construction adds thousands of workers and vehicles to already congested streets. When a job site spills into a lane or blocks a sidewalk, someone has to control that traffic, and that person needs a flagger certification. Any worker directing traffic in an NYC construction zone must complete 4 hours of DOB-approved flagger training before they can legally do so.

This course covers hand signals, traffic control zone setup, and managing real situations on busy NYC streets. The cert is valid for four years and counts toward your SST training hours under Local Law 196. Fast Track's flagger course offers efficient training that opens up more work across NYC sites.

5. 2-Hour Silica Awareness

Most NYC construction workers regularly work around silica dust without realizing how serious the exposure risk is. Cutting, drilling, or grinding concrete, brick, or masonry releases respirable crystalline silica into the air, and breathing it in causes permanent lung damage over time. It does not show up immediately, which is exactly why so many workers underestimate it until it is too late.

Under OSHA standard 1926.1153, silica awareness training is required for construction workers exposed to silica dust. The 2-hour course counts toward your SST training hours under Local Law 196. This makes it one of the most efficient certifications in the Five Card Program. Two hours of training that protect your health and move you closer to a full SST card at the same time.

Where to Get All Your NYC Construction Certifications in One Place

Now that you know what all five certifications are, the next question most workers ask is whether they can get everything done at one school. The answer is yes, and it matters more than most people realize.

Fast Track has heard from new workers who showed up at their first NYC site with a valid OSHA 30 and were sent home because the SST card was incomplete. The more costly version of that story is the worker who completed scaffold training at a school that turned out not to be DOB-approved for that specific cert, had the card rejected on-site, and had to retake the course and pay twice.

The Five Card Program at Fast Track TLG exists specifically to prevent that. All five certifications, one Brooklyn address, one registration, and one DOB-approved provider across every course.

What Is the DOB Worker Wallet, and Do You Need One?

The DOB Worker Wallet combines your specialty training certifications into a single scannable card verified by New York's DOB Training Connect app. It covers scaffold, rigging, mast climber, and gas piping certifications. As of July 1, 2025, it is the only accepted credential for those certifications on NYC construction sites. Workers holding cards issued before November 1, 2024, who have not converted cannot use those old cards on-site.

Who Needs the Five Card Program?

This program is for you if you fall into any of these categories:

• New construction workers who need all five certs sorted before their start date.
• Workers who have some cards but want to complete the full set in one place.
• Workers from other states whose OSHA credentials do not satisfy NYC DOB requirements.
• Foremen who need an entire crew certified without juggling multiple school schedules.
• Workers whose previous training provider turned out not to be DOB-approved for one or more of the five certifications.
