The Americans With Disabilities Act sets guidelines that facilities in California must follow to make hallways wheelchair accessible. It requires that halls measure no less than 36 inches wide for commercial establishments, and the halls must provide a clearance space for turns.
Sufficient passing space
Hallways should include enough space for wheelchair users and others to pass each other comfortably. The ADA requires 60 inches minimum width for passing with passing intervals reasonably spaced. The passing intervals should measure 200 feet minimum. The ADA states that a T-intersection passes requirements.
Checkout lanes
Checkout lanes have their own guidelines. Checkout lanes must be at least 36 inches wide and should include the international wheelchair-accessible sign. All types of checkout aisles must have an accessible lane.
Head room
The ADA requires a clearance of 80 inches to help blind and disabled people prevent injuries from head bumps. If a commercial building has part of an accessible intersection with less than an 80-inch clearance, a barrier should be put in place.
Safe floor surfaces
Surface and floors of hallways must be covered with non-slip materials to prevent falls. The ADA requires carpets to be securely fastened with a maximum pile of half an inch and strips along the exposed edges. Halls that change levels of more than half an inch are required to have platforms or ramps.
Doors
Doors are also required to be accessible to wheelchair users. Doors that open 90 degrees should have a minimum 32-inch opening. Doors that only security personnel can open do not have to follow the guidelines. ADA-compliant door hardware should open with one hand and be 34 to 48 inches above the floor.
Visitors to public establishments are protected under ADA law. If a person with a disability sees that the business has not met ADA compliance, they may be able to take legal action.
