Chicago Building Code MCC Ch. 14B and the International Fire Code §1010 require that doors in egress paths unlock from the inside without keys or special knowledge, with limited exceptions for delayed-egress and classroom barricade hardware.
MCC Ch. 14B-1010 (egress) adopts International Building Code and IFC §1010 standards: doors serving means of egress must open with one releasing motion, use lever or panic hardware in assembly and educational occupancies above 50 occupants, and never require a key, tool, or special knowledge to exit. Delayed-egress locks are allowed in low-hazard occupancies with 15-second release on push, alarms, and signage. Classroom barricade devices that block egress are prohibited unless they meet ANSI/BHMA A156.41 dual-action rules. Stairwell re-entry must be provided at least every fourth floor in high-rise buildings. Chicago Department of Buildings and CFD enforce.
Stop-work orders, certificate-of-occupancy revocation, and fines from $500 to $2,500 per door per day under MCC 14A-1-105. Blocked or chained egress doors are typically prosecuted as fire-code emergencies with immediate closure.
