The IBC Accessible Means of Egress

The IBC includes a requirement for accessible spaces to be provided with not less than one accessible means of egress. Where more than one means of egress are required by Section 1015.1 or 1021.1 from any accessible space, each accessible portion of the space shall be served by not less than two accessible means of egress.

Though there are some exemptions to this rule (Section 1007.1):

  1. Accessible means of egress are not required in alterations to existing buildings.
  2. One accessible means of egress is required from an accessible mezzanine level in accordance with Section 1007.3, 1007.4 or 1007.5.
  3. In assembly areas with sloped or stepped aisles, one accessible means of egress is permitted where the common path of travel is accessible and meets the requirements in Section 1028.8.

The IBC defines the ‘accessible means of egress’ as a continuous and unobstructed way of egress travel from any accessible point in a building or facility to a public way.[1]
