ADA Accessibility

It is incumbent upon the auditorium designer to accommodate those with disabilities and provide equal access to services and conveniences. This is required by the “Americans with Disabilities Act” that became law on July 26, 1990. ADA locations must be part of the seating plan and include locations for wheelchairs and folding / retractable aisle armrests.
