Summary

When a Wilmington building undergoes work covered by the city's Renovation Subcode, any required exit door with a latch must get approved panic hardware once the room or building's occupant load tops 100 people, so the door can't be locked in a way that traps people inside.

All required exit doors equipped with latching devices in buildings or spaces with an occupant load greater than 100 shall be equipped with approved panic hardware.

Full Breakdown

The rule sits inside Sec. 4-191, the Renovation Subcode Wilmington adopted wholesale for existing-building rehab, repeated under each use group's basic-requirements section (assembly groups, business, etc.). It only kicks in for spaces the subcode covers during reconstruction or alteration work, but where it applies, any required exit door fitted with a latching device must carry approved panic hardware once occupant load exceeds 100: a push-bar or crossbar that lets people leave without a key, code, or special knowledge, so an occupied assembly space can never be secured with an ordinary keyed lock on its main exits.

Violations & Fines

Building code violations under this chapter, including panic-hardware noncompliance, are fined $250-$1,000 for a first offense, $500-$2,500 for a second, and $1,000-$5,000 for a third or later offense under Sec. 4-3, with community service allowed in place of or alongside the fine.

Frequently Asked Questions

Does every Wilmington business door need a panic bar?
No. It's required only for exit doors that already have a latching device, in a room or building with an occupant load over 100, when the space falls under the city's Renovation Subcode.
What counts as panic hardware?
A push-bar or crossbar exit device that lets occupants leave without a key, code, or special knowledge, commonly called a crash bar.
What's the penalty for a missing required panic bar?
It's charged as a building code violation under Sec. 4-3, with fines starting at $250-$1,000 for a first offense and rising to $5,000 for repeat offenses.
