How to Apply for a NYC Department of Buildings Contractor's Tracking Number (License)

[Michael Genari]

If you’re planning to work as a General Contractor in New York City, understanding the NYC Department of Buildings (DOB) Tracking Number process is essential. The Tracking Number is, in effect, the contractor’s license with the DOB. Without it, you cannot obtain the work permits necessary to legally begin most projects.

What is a DOB Tracking Number?

A DOB Tracking Number is a unique identifier assigned to General Contractors by the NYC Department of Buildings. It establishes you as the licensed contractor of record for construction work such as:

• Renovations and alterations
• Structural work
• Interior demolition
• Façade repairs
• Other permitted construction activities

It is important to note that a Tracking Number is not for plumbing or trade-specific permits. Separate licenses are required for plumbing, electrical, and other specialized trades.

Tracking Number vs. Registration Number

One common area of confusion is the difference between a Tracking Number and a Registration Number.

• Tracking Number: Your General Contractor’s DOB license number. It allows you to pull permits for interior and exterior renovations, alterations, and interior demolition.
• Registration Number: Required for large-scale projects such as new building construction, building enlargements, or full building demolitions. These types of jobs cannot be performed with just a Tracking Number.

Steps to Apply for a Tracking Number

While the process can vary depending on your company structure and insurance coverage, the general steps include:

1. Application Setup – Provide accurate business details, insurance, and qualifying individual information.
2. Supporting Documentation – Submit proof such as insurance certificates, corporate formation papers, and background checks.
3. Compliance Check – The DOB verifies that you have active insurance coverages, no outstanding DOB penalties, and valid business registration.

Why It Matters

In New York City, construction permits cannot be issued without a valid General Contractor Tracking Number. Attempting to perform work without the proper licensing can result in DOB violations, stop work orders, and fines.

Final Thoughts

For anyone looking to operate as a contractor in NYC, securing a DOB Tracking Number is a critical first step. Understanding its limits—and when a Registration Number is required—helps avoid delays and ensures your projects stay compliant with DOB regulations.

By getting familiar with this process, contractors can better position themselves for success in New York City’s highly regulated construction environment.
