Facts: |
|
Required clearances at doors to enter stairs and at ground level discharge from stair meet the requirements.
Two elevators serve the building.
Handicap parking spaces are located adjacent to the elevators and the stair adjacent to the elevators which will meet the required maneuvering clearances.

2014 IBC 1009.7 |
|
|
|
|
|
Conditions: |
|
The existing Civic Center Parking Garage will have a two level vertical addition with two existing stair towers and one existing elevator tower extended up the additional two levels. The existing stair risers vary in height between existing landings between 7¿ ¿ 7 ¼¿. (1009.7.4) In order to add the new levels of stairs within the existing shaft dimensions the new risers will have to match the existing which exceeds the current code requirements of 7¿ maximum (1009.7.2). The new risers would be maximum 7-3/16¿ and could be consistent between landings.
