Wheelchair Accessible Viewing Positions

Q: How do I calculate the Minimum Number of Wheelchair Accessble Viewing Positions required for a Place of Assembly or Temporary Place of Assembly? What is the minimum dimension

A: Refer to Building Code Section §27-531(a)(1)(h): Performance viewing positions shall be provided for persons who use wheelchairs in accordance with the following schedule:
Capacity of Assembly Space Number of Viewing Positions
75 to 100=4 min
101 to 150= 5 min
151 to 200=6 min
201 to 300=7 min
301 to 400=8 min
401 to 500=9 min
501 to 1000=2 percent of total
Over 1000=20 plus 1 for each 100 over 1000

Minimum Dimensions of Viewing Position = 30" wide x 48" deep

These positions shall be located so as not to interfere with egress from any row of seats and shall be reachable by means of ramps and/or elevators. Steps shall not be allowed in line of travel from the main approach entry to the designated locations. Size and placement of wheelchair locations, surfaces, access to performing area and listening systems where required, shall comply with the provisions of reference standard RS-4-6. These positions may be utilized by persons who do not use wheelchairs provided that the positions are delineated on the approved seating plans, the seating is readily removable and the positions are unsold one full working day before the performance.
