Custom Outdoor Blade & Bracket Signs NYC
Double-Sided Projecting Blade Signs Built for NYC Foot Traffic

Blade Signs NYC: Frequently Asked Questions
What is a blade sign and why is it essential for NYC storefronts?
A blade sign (also known as a projecting sign or flag sign) mounts perpendicular to your building facade, projecting over the sidewalk. In dense pedestrian cities like New York, blade signs capture the attention of foot traffic walking in both directions long before they reach your front door.
Do blade signs require Department of Buildings (DOB) permits in NYC?
Yes. Projecting signs extending over NYC public sidewalks generally require DOB sign permits, structural wind-load engineering, and licensed Master Sign Hanger installation. SignsRiver handles all architectural drawings, landmark commission reviews, and DOB filings.
What are the NYC code requirements for projecting sign height and clearance?
NYC building code requires projecting blade signs to maintain a minimum clearance of 10 feet from the sidewalk grade to the bottom of the sign cabinet. Signs must also adhere to maximum projection and square footage limits based on your zoning district.
Can blade signs be internally illuminated for nighttime visibility?
Yes! We manufacture LED push-through acrylic blade signs, halo-lit edge-glow signs, and custom illuminated lightbox cabinets with energy-efficient UL-listed LED modules for 24/7 visibility.
How long does it take to design, fabricate, and install a custom blade sign in NYC?
Custom fabrication typically takes 2 to 3 weeks once designs and permits are approved. We provide 3D visual proofs, structural mounting details, and turnkey installation across Manhattan, Brooklyn, Queens, Bronx, and Staten Island.
