JUMP TO FULL CODE CHAPTER
The following is a list of special terms used in this chapter:

- Food Court. A public seating area located in a mall concourse that serves adjacent food preparation tenant spaces. (See 126.96.36.199.)
- Gross Leasable Area. Fifty percent of major tenant areas, and 100 percent of all other floor areas designated for tenant occupancy and exclusive use, including storage areas. The area of tenant occupancy is measured from the centerlines of joint partitions to the outside of the tenant walls. (See 188.8.131.52)
- Mall Concourse. A common pedestrian area within a mall structure that serves as access for two or more tenants and does not exceed three levels that are open to each other. (See 3.3.175.)
- * Open Mall Concourse. A mall concourse that either (1) has 50 percent or more of the total area of the solid mall concourse perimeter walls and solid roof area open to the atmosphere with openings distributed uniformly over the length of the mall concourse, or (2) has an approved open mall concourse engineering analysis.
- Enclosed Mall Concourse. A mall concourse that does not meet the definition of open mall concourse.
- *Mall Structure. A single building enclosing a number of tenants and occupancies wherein two or more tenants have a main entrance into one or more mall concourses. For the purpose of this chapter, anchor buildings shall not be considered as a part of the mall structure. (See 3.3.282.4.)
- Major Tenant. A tenant space, in a mall structure, with one or more main entrances from the exterior that also serve as exits and are independent of the mall concourse. (See 3.3.174.)
The mall structure shall be treated as a single building for the purpose of calculation of means of egress and shall be subject to the requirements for appropriate occupancies, except as modified by the provisions of 37.4.4, and the mall concourse shall be of a clear width not less than that needed to accommodate egress requirements as set forth in other sections of this Code.
A mall concourse shall be permitted to be classified as an open mall concourse where an approved engineering analysis demonstrates that the mall concourse is designed to keep the smoke layer interface at 6 ft (1830 mm) above the highest walking level surface open to the mall concourse, for a period equal to 1.5 times the calculated egress time or 20 minutes, whichever is greater.
An additional 200 ft (61 m) shall be permitted for travel through the enclosed mall concourse or 300 ft (91 m) for travel through the open mall concourse, provided that all the following requirements are met:
- *The mall concourse shall be of a clear width not less than that needed to accommodate egress requirements, as set forth in other sections of this chapter, but shall be not less than 20 ft (6100 mm) wide in its narrowest dimension.
- On each side of the mall floor area, the mall concourse shall be provided with an unobstructed exit access of not less than 10 ft (3050 mm) in clear width parallel to, and adjacent to, the mall tenant front.
- *The exit access specified in 184.108.40.206.2(2) shall lead to an exit having a width of not less than 66 in. (1675 mm).
- The mall concourse, and all buildings connected thereto, except open parking structures, shall be protected throughout by an approved, supervised automatic sprinkler system in accordance with 220.127.116.11(1).
- Walls dividing tenant spaces from each other shall extend from the floor to the underside of the roof deck, to the floor deck above, to a ceiling that is constructed to limit the transfer of smoke or to the ceiling where the wall is constructed with a fire resistance rating of not less than 1 hour and all of the following also shall apply:
- *Malls with a floor opening connecting more than two levels shall be provided with a smoke control system.
During all times that the mall concourse is occupied, the required fire alarm system, once initiated, shall perform one of the following functions:
Rooms housing building service equipment, janitor closets, and service elevators shall be permitted to open directly onto exit passageways, provided that all of the following criteria are met:
- The required fire resistance rating between such rooms or areas and the exit passageway shall be maintained in accordance with 18.104.22.168.
- Such rooms or areas shall be protected by an approved automatic sprinkler system in accordance with 22.214.171.124(1), but the exceptions in NFPA 13 allowing the omission of sprinklers from such rooms shall not be permitted.
- Service elevators opening into the exit passageway shall not open into areas other than exit passageways.
- Where exit stair enclosures discharge into the exit passageway, the provisions of 126.96.36.199.8 shall apply, regardless of the number of stories served.
Within every store or level, and from sidewall to sidewall of each tenant space facing the mall concourse, plastic signs shall comply with all of the following:
- Plastic signs shall not exceed 20 percent of the wall area facing the mall concourse.
- Plastic signs shall not exceed a height of 36 in. (915 mm), except if the sign is vertical, in which case the height shall not exceed 8 ft (2440 mm) and the width shall not exceed 36 in. (915 mm).
- Plastic signs shall be located a minimum distance of 18 in. (455 mm) from adjacent tenants.
- Plastics, other than foamed plastics, shall meet one of the following criteria:
- They shall be light-transmitting plastics.
- They shall have a self-ignition temperature of 650°F (343°C) or greater when tested in accordance with ASTM D1929, Standard Test Method for Determining Ignition Temperatures of Plastic, and a flame spread index not greater than 75 and a smoke developed index not greater than 450 when tested in the manner intended for use in accordance with ASTM E84, Standard Test Method for Surface Burning Characteristics of Building Materials, or ANSI/UL 723, Standard for Test for Surface Burning Characteristics of Building Materials.
- The edges and backs of plastic signs in the mall concourse shall be fully encased in metal.
- Foamed plastics shall have a maximum heat release rate of 150 kW when tested in accordance with ANSI/UL 1975, Standard for Fire Tests for Foamed Plastics Used for Decorative Purposes, or in accordance with NFPA 289 using the 20 kW ignition source.
- Foamed plastics shall comply with all of the following:
- The density of foamed plastic signs shall be not less than 20 lb/ft3 (320 kg/m3).
- The thickness of foamed plastic signs shall be not greater than 1/2 in. (13 mm).
Kiosks and similar structures (temporary or permanent) shall not be considered as tenant spaces and shall meet all of the following requirements:
- Combustible kiosks and similar structures shall be constructed of any of the following materials:
- Fire-retardant-treated wood complying with the requirements for fire-retardant-impregnated wood in NFPA 703
- Light-transmitting plastics complying with the building code
- Foamed plastics having a maximum heat release rate not greater than 100 kW when tested in accordance with ANSI/UL 1975, Standard for Fire Tests for Foamed Plastics Used for Decorative Purposes, or in accordance with NFPA 289, using the 20 kW ignition source
- Metal composite material (MCM) having a flame spread index not greater than 25 and a smoke developed index not greater than 450 in accordance with ASTM E84, Standard Test Method for Surface Burning Characteristics of Building Materials, or ANSI/UL 723, Standard for Test for Surface Burning Characteristics of Building Materials, when tested as an assembly in the maximum thickness intended for use
- Textiles and films meeting the flame propagation performance criteria contained in Test Method 1 or Test Method 2, as appropriate, of NFPA 701
- The minimum horizontal separation between kiosks, or groups of kiosks, and other structures within the mall concourse shall be 20 ft (6100 mm).
- Each kiosk, or group of kiosks, or similar structure shall have a maximum area of 300 ft2 (27.8 m2).
