OCCUPANCY CALCULATIONS
ALLOWABLE OCCUPANCY CALCULATION BREAKDOWN: IBC 2018, TABLE 1004.5
*Stacks/Library/Secured Stacks - “Stacks” = 100 gross sqft per occupant
*Faculty/Student Offices/Print Room - “Business” = 150 gross sqft per occupant
*Mechanical/Vertical Chases - “Mechanical” = 300 gross sqft per occupant
*Practice Room/Studio Space = “Vocational” = 50 net sqft per occupant
*Rehersal Space/Seminar Room - “Assembly Fixed” = 1 fixed seat per occupant
*Lobby/Seating Area/Computer Lab/Break Room/Conference Room“Assembly Unconcentrated” = 15 net sqft per occupant
*Classrooms - “Classroom” = 20 net sqft per occupant
*Storage Room/Janitor Closet/Tech Storage - “Storage” = 300 gross sqft per occupant
*Open Reading Room/Private Reading Room - “Reading Room” = 50 net sqft per occupant
*Performance Space - “Stage” = 15 net sqft per occupant
*Restrooms/stairs/corridors - does not classify as occupiable spaces
MINIMUM NUMBER OF EXITS OR ACCESS TO EXITS PER STORY:
IBC 2018 table 1006.3.2
*Basement = 2 exit staircases
*First Floor = 3 exits
*Second Floor = 2 exit staircases
*Third Floor = 2 exit staircases
IBC 2018 section 1007.1.1, exception 2
*Distance between two exits, exit access doorways, or ramps, shall be placed no more than 1/3 of the maximum overall diagonal length apart from another.
*Overall diagonal length = 199’-10 1/2”
*Distance between means of egress = 199’-10 1/2“ x 0.333 = 65’-5 1/2”
EGRESS STAIR REQUIREMENTS:
IBC 2018 section 1005.3.1, exception 1
*Width = multiply the occupant load by the capacity factor of 0.2”
*Widths meeting requirements shall be dimensioned in plan
IBC 2018 section 1011.5.2
*Stair riser heights = 7” maximum and 4“ minimum
*Stair treads = 11” minimum in depth
*Per IBC 2018 section 1011.5.4, stair treads and risers should be uniform in shape and size
IBC 2018 section 1014.1
*Handrails = must be on both sides of stairway
* Handrail height = 34“ minimum, measured above stair tread nosings with a 38” maximum
IBC 2018 1009.3.3
*Area of refuge is not required in an automatic sprinkler system building per 2
EGRESS EXIT REQUIREMENTS:
IBC 2018 section 1005.3.2, exception 1
*Width = multiply the occupant load that will be utilizing the specific exit by 0.15”
*Widths of egress exits meeting requirements shall be dimensioned in plan
IBC 2018 section 1010.1.2
*Door swings = pivoted or side-hinged and must swing in the direction of egress travel
IBC 2018 table 1020.1
*Corridor fire resistance rating = not required for a building with sprinkler system
IBC 2018 section 1003.3
*Clearance = minimum headoom of 80” over any circulation paths for egress
ACCOMMODATIONS FOR ACCESSIBLE MEANS OF EGRESS:
IBC 2018 section 1009.1
*Required accessible means = no less than one accessible means of egress in a building
IBC 2018 section 1009.3
*Stairways = clear width of 48” minimum is not required for a building with sprinkler system, per exception 2
IBC 2018 section 1009.4
*Elevators = 4 or more stories above or below a level of exit discharge, a minimum of 1 accessible elevator must be provided and equipped with standby emergency power
MAXIMUM PATH OF TRAVEL:
IBC 2018 table 1017.2
Maximum travel distance for B (Business) occupancy = 300 feet
FIRST FLOOR EGRESS DOOR REQUIREMENTS AND CALCULATIONS
IBC 2018 section 1006.3.2, exception 1
*Number of doors required = 3
*Width - occupant load served by door as a means of egress x 0.15”
Door 1 = 36 occupants x 0.15” = 5.4“ ”
Door 2 = 57 occupants x 0.15” = 8.55”
Door 3 = 228 occupants x 0.15“ = 34.2” = 2’-10 2/3“
Door 4 = 539 occupants x 0.15” = 80.85” = 6’-8 7/8”
Door 5 = 509 occupants x 0.15” = 76.35” = 6’ 4 3/8”
BUILDING EGRESS STAIR REQUIREMENTS AND CALCULATIONS:
IBC 2018 section 1005.3.1, exception 1
*Width - floor’s occupancy load x 0.2 with an absolute minimum of 44“
*Third floor stair widths = 145 occupants x 0.2” = 29“ = absolute minimum 44”
*Second floor stair widths = 500 occupants x 0.2” = 7’-0“
*Basement floor widths = 213 occupants x 0.2” = 42.6” = absolute minimum 44”
