Guide to the ADA Standards

When an addition increases the number of stories or square footage beyond the maximum permitted by the exception, is an accessible route between stories required?

If a facility no longer qualifies for the exception for multi-story facilities due to an increase in square footage or stories, an accessible route between stories is required where the work also includes installation of a stair or escalator where none existed previously and major structural modifications are needed (unless a compliant accessible route between stories already exists). The accessible route must connect the levels served by the new stair or escalator. Also, if the addition includes a primary function area, an accessible path of travel to the primary function area is required, including where it involves travel between stories or levels, to the extent the cost does not exceed 20% of the cost of the overall alteration. Compliance in an alteration, including with the requirement for an accessible route between stories, is not required where it is “technically infeasible.” In this case, compliance is required to the maximum extent feasible.
