Which feature is NOT typically required by ADA accessibility guidelines?

• A. Narrow corridors with step access.
• B. Barrier-free design including ramp slopes.
• C. Accessible routes and door widths.
• D. Clear signage for directions.

Answer: (A)

ADA accessibility guidelines aim to remove barriers and provide barrier-free routes for people with disabilities. This means designing spaces with accessible paths, ramps or other means to handle changes in level, and ensuring doorways and corridors are wide enough for wheelchair users. Clear signage helps everyone navigate.

Having narrow corridors with steps directly creates obstacles for mobility devices and contradicts the goal of an accessible route. If a space has steps, an accessible alternative—such as a ramp or lift—must be provided to meet the guidelines.

The other features—barrier-free design with appropriate ramp slopes, accessible routes and door widths, and clear signage—are consistent with ADA requirements, helping ensure safe and independent access.
