When you need a DOB permit
The default answer is: most signs require one. Specifically:
- Illuminated signs (neon, LED, backlit channel letters, internally lit boxes)
- Projecting signs (any sign extending from the building face)
- Rooftop signs
- Awning signs (the awning itself typically needs a permit, with the lettering treated as the sign)
- Wall signs above a certain size threshold based on your zoning district
Small flat non-illuminated wall signs below the threshold may be permit-exempt, but the threshold varies by zone. Assume you need a permit until you have written confirmation otherwise.
Landmark districts
If your building sits in a landmark district or is an individually designated landmark, the Landmarks Preservation Commission (LPC) must approve any exterior change before the DOB will process your permit. This includes:
- New signs (any type)
- Changes to existing signs
- Awnings
- Paint color changes
- Window frame or storefront changes
LPC approval is its own process with its own timeline. Budget several weeks and consult with the LPC staff before committing to a design.
Zoning considerations
The NYC Zoning Resolution sets size, placement, and illumination limits by zoning district. A commercial C4-2 district allows larger and brighter signs than a residential R5 district that happens to have a storefront on the ground floor. Know your district before you design.
Fine schedule for unpermitted signs
| Unpermitted illuminated or projecting sign | $800 to $5,000 plus DOB stop-work order |
| LPC violation in landmark district | $500 to $10,000 |
| Prices not posted (where DCA requires it) | $250 to $1,000 |
Price posting (a separate DCA requirement)
Food service establishments, hair salons, and certain other business types are required to post prices visibly. This is enforced by DCA, not DOB, but is often caught during the same inspection cycle as signage issues.
