Required Signage for Construction Sites in NYC: NYC DOB Regulations

Construction sites in New York City must follow strict safety and compliance regulations to protect workers, pedestrians, and the surrounding community. One critical aspect of these regulations is the mandatory signage required by the NYC Department of Buildings (DOB). These signs serve multiple purposes, including worksite safety, regulatory compliance, and public awareness. Failure to install the correct signage can result in violations, fines, or work stoppages.

This page provides an in-depth guide on the required signage at construction sites in NYC, including their purpose, placement, and compliance with DOB, OSHA, and local laws.


1. Work in Progress Sign

What Is It?

A Work in Progress (WIP) sign is a required posting at all active construction, alteration, or demolition sites. It informs the public about the project and helps maintain transparency.

Required Information:

  • Project name and address

  • Contractor’s name and contact information

  • Rendering or elevation drawing of the building

  • Project’s anticipated completion date

  • Type of zoning use (residential, commercial, etc.)

Regulations:

  • Must be at least 36” x 48” in size

  • Printed in legible, weather-resistant material

  • Placed in a visible location at the site entrance

Failure to post a Work in Progress sign may result in DOB violations.


2. Sidewalk Shed and Construction Fence Signage

What Is It?

Sidewalk sheds and construction fences are required for safety at many work sites, and they must include specific signage panels.

Required Information:

Safety signs warn workers and pedestrians about hazards, restricted areas, and safety protocols at construction sites. These include:

  • Danger Signs (e.g., “Hard Hat Area,” “Falling Debris”)
