The Real-Time Enforcement Unit in NYC: Why Owners and Contractors Should Avoid Getting on Their Bad Side
The Real-Time Enforcement Unit in NYC: Why Owners and Contractors Should Avoid Getting on Their Bad Side

If you're a building owner or contractor in NYC, there’s one
enforcement team you never want to deal with—the Real-Time
Enforcement (RTE) Unit.
This unit, created under Mayor Bill de Blasio’s administration, was designed to crack down on illegal construction, unsafe building practices, and repeat offenders. What many don’t realize is that the RTE Unit evolved from what was once called the Building Marshal’s Office—a unit that had limited oversight and was mostly reactive. Under de Blasio’s push for stricter building safety enforcement, RTE was formed as a more aggressive, data-driven, and proactive enforcement arm of the NYC Department of Buildings (DOB).
Why Was the Real-Time Enforcement Unit Created?
De Blasio’s administration pushed for safer construction sites, stronger tenant protections, and more accountability for property owners and contractors. Before RTE, the Building Marshal’s Office focused mostly on issuing stop-work orders and collecting unpaid fines. While they did catch violators, their enforcement was sporadic and they only operated during business hours.
Then came a rise in construction accidents, illegal renovations, and even building collapses—many of which could have been prevented with better oversight. The solution? Real-Time Enforcement (RTE).

What Makes the RTE Unit Different?
- They operate nearly 24/7. Unlike regular DOB inspections, RTE teams work late nights, early mornings, and even weekends—especially in areas where illegal work is often done after hours.
- They act fast. Instead of waiting for complaints to pile up, they use data tracking, 311 complaints, and ongoing violations to proactively target buildings and job sites with a history of problems.
- They shut down unsafe and illegal work immediately. If they show up, it’s usually not just to issue a violation—they come with the power to impose Stop-Work Orders, evacuations, and emergency repairs right on the spot.
- They coordinate with other agencies. The RTE Unit doesn’t work alone—they collaborate with the Fire Department (FDNY), Housing Preservation & Development (HPD), and even law enforcement to go after serial violators.
If your site gets flagged by RTE, it’s not just a minor problem—you’re now on the radar of some of the most aggressive building enforcers in NYC.

Why You Don’t Want to Get on the RTE Unit’s Radar
Let’s be real—violations are common in NYC construction. Even the most experienced professionals occasionally run into compliance issues. However, 99 times out of 100, violations happen because someone—whether the owner, architect, contractor, or all three—decided to gamble to save money.
You might get away with it for a while, but the one time you get caught, you’ll lose everything you ever saved—and then some.
What Happens If the RTE Unit Catches Violations on Your Site?
Immediate Stop-Work Orders (SWOs) – Your project is shut down instantly. No warnings. No negotiations.
Massive Fines – Unlike standard DOB penalties, RTE violations come with some of the highest fines in the industry, often reaching tens or even hundreds of thousands of dollars.
Contractor & Owner Accountability – If violations are severe, the DOB can suspend or revoke contractor licenses, take away building permits, or even refer cases for criminal prosecution.
Increased Scrutiny on Future Projects – Once you’re on their radar, expect every future project to get more inspections, more fines, and more oversight.
Fire Watch & Emergency Repairs – If they determine the site is an immediate safety hazard, they can require you to pay for a 24/7 fire watch, stabilize unsafe conditions, or even evacuate tenants—all at your expense.

Common Mistakes That Put You on the RTE Unit’s Radar
Most of the time, when the RTE Unit gets involved, it’s because someone tried to cut a corner. Here’s what often leads to an RTE investigation:
- Skipping Permits or Filing the Wrong Ones – Trying to pass off major work as "minor repairs" will catch up to you fast.
- Illegal Demolition or Structural Modifications – Removing load-bearing walls or altering fire barriers without approval will trigger immediate action.
- Unsafe Work Conditions – Unprotected fall hazards, worker injuries, or improper scaffolding get RTE involved quickly.
- Violating Stop-Work Orders – If you keep working after getting an SWO, you’re begging for trouble.
- Not Fixing Prior Violations – If the DOB already flagged you, but you ignored it, expect a surprise visit from the RTE team.
The Cost of Cutting Corners vs. The Cost of Doing It Right
Many owners and contractors convince themselves that taking shortcuts is worth the risk. The problem? When the RTE Unit catches you, that one time will cost you everything you ever saved.
You Lose Every Penny You Saved – Between fines, legal fees, emergency work orders, and lost time, you could end up paying ten times more than you would have spent doing things correctly from the start.
Your Project is Delayed for Months – Work stops until every violation is corrected, meaning your job site sits idle while expenses pile up.
Your Future Jobs Are Under More Scrutiny – Now you’re on the RTE’s watchlist, so every future project gets extra inspections, making it harder to cut corners.
You Risk Losing Your License or Property Value – Contractors can lose their licenses, and owners can be forced to sell or rebuild at major losses.
Now, compare that to doing it right:
You Pay for Permits Upfront– But you avoid massive penalties later.
You Use Licensed Contractors and Architects – Who file plans correctly and keep things compliant.
You Address Issues as They Come – Instead of hiding them and hoping no one finds out.
Yes, NYC construction is expensive. But the cost of getting caught is far worse.
How to Avoid RTE Trouble: Do Everything as Right as Possible
You don’t need to be perfect—mistakes happen. But if you consistently try to do things the right way, you’ll avoid majortrouble.
Hire the Right Professionals – Work with licensed, experienced contractors, architects, and engineers.
File for the Correct Permits – Don’t try to pass off major renovations as minor repairs.
Fix Violations Immediately – If you get a notice, correct the issue fast before it escalates.
Keep Your Site Safe – Worker safety violations will get RTE on your case quickly.
Don’t Gamble – If a decision feels risky, it’s probably not worth it.
Final Thought: The RTE Unit is a Nightmare You Can Avoid
The Real-Time Enforcement Unit was created to crack down on those who try to cheat the system. You might get away with it once, twice, or ten times—but the one time you get caught will cost you everything.
The smartest way to avoid them? Follow the rules, do things properly, and don’t give them a reason to show up.
Because when the RTE Unit comes knocking, you don’t want to be the one answering the door.
