How wide does a stairway need to be in order to use a stair lift?
Most stair lifts are designed to fit in a standard 36″ wide stairway. When the seat is folded, most stair lifts only take up 13″ – 15″ of the stairway. This leaves ample room for someone to pass by the lift when it is not in use. Elevator code dictates there be a minimum of 20″ of clearance when the unit is folded and not in use.
