Dallas Building Safety: Door Locking Hardware Rules (2026)

Under IFC 1010 as amended by Dallas, every door along a means of egress must be readily openable from the egress side without the use of a key, tool, or specialized knowledge. Single-action operation is required, except for residential dwellings allowing one deadbolt above the latch. Assembly spaces with occupant loads of fifty or more require panic or fire-exit hardware. Classroom barricade devices are limited to those meeting BHMA A156.41 standards and must permit free egress, override by staff, and quick release in emergencies. Electrified locks need fail-safe release on alarm, power loss, or sensor activation. Detention, healthcare, and childcare facilities have specific delayed-egress allowances of fifteen seconds with signage and alarm activation.
