NYC DOB safety sign requirements apply to all active construction sites in 2026. Contractors must display specific signage to remain compliant, avoid violations, and maintain a safe job site. Failure to follow NYC Department of Buildings (DOB) signage rules can result in fines, stop-work orders, or inspection delays.
This 2026 contractor guide explains every mandatory sign, where each sign must be installed, and how to stay aligned with official NYC DOB safety sign requirements.
NYC DOB Safety Sign Requirements (2026 Overview)
All construction, renovation, demolition, and façade repair sites must comply with NYC DOB signage regulations under the New York City Building Code.
Below are the required signs most commonly inspected in 2026.
Work in Progress (WIP) Sign
The Work in Progress (WIP) sign is required on all construction and renovation projects.
Required Sizes:
- 36.5″ × 55″ → lots under 60 ft frontage
- 48″ × 72″ → lots over 60 ft frontage
Must Include:
- Project description
- Permit number
- Property owner
- Contractor information
- Emergency contact number
The WIP sign must be installed in a visible location facing the public right-of-way.
Sidewalk Shed Sign (Scaffolding Sign)
When a sidewalk shed is installed under Building Code §3307, proper signage is required.
Must Include:
- Contractor name
- Phone number
- Permit number
- Job address
- Website (if applicable)
Scaffolding signage must be clearly visible from the sidewalk.
Demolition Sign
Demolition projects (partial or full) must display a demolition notice under Building Code §3303.
Must Include:
- Demolition contractor name
- Job number
- Site contact
- Emergency phone number
This sign helps ensure transparency and safety compliance during demolition operations.
SST Training Requirement Sign (Local Law 196)
Under Local Law 196, most construction sites must display an SST Training Requirement sign.
The sign must clearly state:
- 40-hour worker training requirement
- 62-hour supervisor training requirement
- 30-hour temporary requirement (for older permits)
This sign informs workers of mandatory safety training standards before entering the job site.
Safety & Hazard Signs (Based on Site Conditions)
NYC DOB safety sign requirements also include hazard signage based on job site conditions.
Common required safety signs include:
- Danger: Overhead Work
- Hard Hat Area
- Eye Protection Required
- No Unauthorized Personnel
- Caution: Work Area
- Pedestrian Walkway
- Fire Extinguisher Location
These signs help pass safety inspections and reduce contractor liability.
Tenant Protection Plan (TPP) Notice
If construction occurs in an occupied building, a Tenant Protection Plan (TPP) notice is required.
The notice must outline:
- Noise mitigation procedures
- Dust control measures
- Fire safety plan
- Emergency access instructions
Failure to display TPP information can result in DOB violations.
After Hours Variance (AHV) Sign
Sites performing work outside standard NYC DOB hours must post an After Hours Variance sign.
Must Include:
- AHV permit number
- Approved work hours
- Contact information
This ensures compliance with DOB after-hours regulations.
Optional but Common Contractor Signs
While not legally required, many contractors install additional signage for organization and branding:
- 4′ × 4′ custom scaffold branding signs
- No Parking Construction Zone signs
- Delivery entrance signs
- Dumpster / debris chute signs
- Emergency assembly point signage
These signs improve site management and brand visibility.
