Steps
Determine the sign's weight and face area.
If the sign is up to 150 square feet in face area and 1,200 pounds, a Special Sign Hanger license is sufficient to perform the hoisting/hanging/attaching work.
If the sign exceeds either threshold, only a Master Sign Hanger license qualifies to perform or supervise the work.
Verify which license class the individual physically doing the installation holds, not just the filing contractor's credentials, via DOB license verification.
For Master Sign Hanger applicants, confirm 5 years of experience as a designated sign-hanging foreman under a licensed Master Sign Hanger within the prior 7 years, since DOB checks this history.
Known gotchas
A Special Sign Hanger license does not scale to larger signs; exceeding the 150 sq ft / 1,200 lb ceiling mid-project requires a Master Sign Hanger.
The permit-holding contractor and the person physically hanging the sign can be different license holders; confirm the on-site installer's license class matches the sign size.
