2) Exits from enclosed grandstand spaces which empty into open grandstand spaces from which occupants can make their way to a safe location or which are a safe area of refuge can be counted as part of the required exit capacity for the enclosed spaces.
3) The occupant load of enclosed grandstand spaces shall be based on the seating capacities of these spaces plus an allowance for standees' floor area, if any, based on one person for every 10 sq ft. of net standing floor area. Required aisle space serving the fixed seats shall not be used when computing net standing floor area.
4) Automatic sprinklers shall be installed in accordance with Section 7.3 (41 Ill. Adm. Code Section 150.70(c)) throughout all enclosed grandstand areas of unprotected combustible construction. If the roof structure alone is combustible, sprinklers shall be required only in all concealed roof spaces.
5) Automatic sprinklers shall be installed in all grandstands in the following locations:
A) All spaces used for storage and maintenance having an area of over 100 sq. ft. and that are not enclosed with at least 1-hour fire resistive construction and fire doors. Automatic sprinklers may be supplied by the domestic water system up to a limit of 20 sprinklers per space provided that a density of at least .15 gallons per minute (GPM) per sq. ft. in the space can be provided. Such shall also be enclosed with at least 1-hour fire resistive construction and an approved self-closing fire door when deemed necessary by the Fire Marshal.
B) Inside combustible concealed spaces of over 2500 sq. ft. fire area.
C) All spaces used for displays or exhibitions or storage of display or exhibition materials.

1) Construction Classification
Structures used as barns shall be classified as follows:

Class B – Walls masonry; roof of combustible materials.
Class C – Walls and roof of combustible material.
2) Size Limitations:
A) Buildings used as barns constructed after the adoption of these rules shall not exceed in area the values in the following table:
Barn Size Limitations
Maximum Building Area in Square Feet
B) Class B and Class C construction without sprinkler protection shall not be permitted.
3) Height Limitations: The height of barns used primarily for horses shall not exceed one story. Where dormitory rooms are located above the barn structure the structure shall not exceed 2 stories in height.
4) Spacing Requirements:
A) Structures enumerated in Section 5.2 (41 Ill. Adm. Code Section (150.50(b)) constructed after the adoption of these rules shall be separated by the following minimum distances:

Adm. Code Section 150.70(c)).
5) Fire Walls: Barns divided by a fire wall having at least two-hour fire resistance shall be considered as separate buildings in applying the size limitations of Section 5.22 (41 Ill. Adm. Code 150.50(b)(2)(A)).
A) Fire walls when required shall extend through combustible roofs and walls. The height of the wall shall be at least 32" above the roof and the side shall extend at least 24" beyond combustible exterior walls.
B) All openings in fire walls separating barns shall be protected by self-closing 1½ hour "B" label fire doors.
6) Exits: Barns shall be designed so that there is a doorway leading directly outside within 100 ft. travel distance of all portions of the building. It shall be possible to exit from any point in the building in at least two directions; dead ends longer than 30 ft. shall not be permitted. Travel distance may be increased to 150 ft. when the barn is of masonry or masonry veneer construction and is protected by an automatic sprinkler system.
A) Doorways provided to meet the requirements of Section 5.26 (41 Ill. Adm. Code Section 150.50(b)(6)(A)) shall be at least 8 ft. high and 6 ft in width.
