19 303.1 ASSEMBLY GROUP A Where persons gather for civic, social, or religions functions; recreation; food or drink consumption; and similar activities, the function is considered assembly in nature. Classification as a Group A occupancy is typically warranted, unless the space is relatively small or the occupant load is relatively low. The reference to Chapter 11 was also removed as it was deemed unnecessary in the application of accessibility provisions as they apply to assembly areas.

20

21 303.3, OCCUPANCY CLASSIFICATION OF COMMERCIAL KITCHENS Commercial kitchens have historically been characterized as two different types, t that are directly associated with a restaurant or similar dining facility and those that are independent of any related dining area, such as a catering business.

22

23 310.6 USES CLASSIFIED AS GROUP R-4 OCCUPANCIES The direct relationship between Groups I-1 and R-4 is now more obvious because the laundry list of such types of uses is consistent between both occupancy groups. The only difference between the two classifications is the number of care recipients, as the expectation for both occupancy groups is that the individuals, although supervised, are individually capable of responding to an emergency without physical assistance from others.

24

25 402 OPEN MALL BUILDINGS This allows for the proper application of a variety of provisions, including those dealing with floor area and means of egress. By definition, the perimeter line encircles all buildings which comprise the open mall building, including the open-air walkways and courtyards HIGH RISE BUILDINGS FIRE SERVICE ACCESS ELEVATORS There was an increase of fire service elevators required in applicable high rise buildings from one to two where multiple elevators are provided in the building, except for those buildings that are provided with only a single elevator. A minimum of two fire service elevators better ensures that there will be a fire service access elevator available for the firefighters use in the performance of their duties. The Florida Legislature has put the 2 nd required fire service elevator on hold for opne years.

26

27 OPEN PARKING GARAGES OPENINGS BELOW GRADE The aggregate length of the openings considered to be providing natural ventilation shall be not less than 40 percent of the perimeter of the tier. Interior walls shall be not less than 20 percent open with uniformly distributed openings. Exception: Exception: Openings Openings are are not not required required to to be be distributed distributed over over percent of the building perimeter where the required openings are percent uniformly of distributed the building over perimeter two opposing where the sides required of the building. openings are uniformly distributed over two opposing sides of the building OPEN PARKING GARAGES HEIGHT AND AREA INCREASES A change in the method of calculating opening percentage was made that uses 7 feet as the maximum height to be used when determining the interior area of each tier. In the determination of permitted area and height increases, the revised measurement method removes the unnecessary requirement for larger exterior openings based upon a tier height that exceeds the required minimum.

28 AIRCRAFT HANGAR FIRE AREAS This change allows allows the the square square footage footage of of ancillary ancillary spaces not spaces considered not considered to be to a direct be a direct part of the aircraft part servicing of the area aircraft to servicing not be included area to not in be the calculation of included the fire area. in the calculation of the fire area. This change reduces the the required required minimum minimum 2-hour fire barrier to to a 1-hour a 1-hour fire fire barrier. barrier INSIDE STORAGE, DISPENSING, AND USE OF HAZARDOUS MATERIALS The scoping provisions regarding the inside storage, dispensing, and use of hazardous materials have been revised to provide consistency with those of the Florida Fire Prevention Code.

29 422 AMBULATORY CARE FACILITIES In a multi-tenant or mixed-occupancy building where there are uses present other than an ambulatory care facility, a fire partition is now required between the care facility and those nonrelated spaces where the ambulatory care facility is intended to have at least four care recipients incapable of self-preservation at any one time ADDRESS IDENTIFICATION A fire code official can now require that address numbers be placed in multiple places when necessary to allow better response of emergency services. All address numbers shall be maintained.

30 MEZZANINE MEANS OF EGRESS The specific provisions for mezzanine means of egress have been deleted and replaced with a general reference to Chapter 10. As a result, the means of egress requirements for a mezzanine are consistent with those for other portions of the building regulated as the exit access. The consideration of an elevated floor level as a mezzanine no longer provides any special allowances for means of egress purposes ALLOWABLE AREA FRONTAGE INCREASE The method of calculating the appropriate allowable area increase for buildings fronting on public ways and/or open space has been clarified. Weighted average: W (L1 X w1 + L2 X w2 + L3 X w3 )/F where Ln = Length of a portion of the exterior perimeter wall. Wn = Width of open space associated with that portion of the exterior perimeter wall. F = Building perimeter that fronts on a public way or open space having a width of 20 feet (6096 mm) or more.

31 507.1 UNLIMITED AREA BUILDINGS ACCESSORY OCCUPANCIES The allowance for occupancy groups not contained under the unlimited area building provisions of Section 507, is now contained under Section 508.2, per the code text. Exception: Other occupancies shall be permitted in unlimited area buildings in accordance with the provisions of Section INCIDENTAL USES GENERAL PROVISIONS This change clarified the concept of individual uses by eliminating the previous understanding with mixed-occupancy provisions. Incidental uses will no longer be separated from building classifications.

32 TABLE Incidental Accessory Occupancies Uses TABLE 509 INCIDENTIAL USES ROOM OR AREA SEPARATION AND/OR PROTECTION Laboratories and vocational shops, not classified as Group H, located in a Group E or I-2 occupancy Laundry rooms over 100 sq. fl.

97 & PONDING INSTABILITY The definition of susceptible bay was added to Chapter 2 to coordinate with ASCE 7, and to identify where ponding must be considered in roof design, addresses this with snow load conditions, which is not applicable in FL. However, addresses the instability for rain load conditions. Susceptible bay provisions apply solely to roofs with a slope less than ¼-inch per foot; or on which water is impounded upon it, in whole or in part, and the secondary drainage system is functional but the primary drainage system is blocked. Any roof with a slope of ¼-inch per foot or greater towards points of free drainage is NOT a susceptible bay DETERMINATION OF WIND LOADS This change is an update and coordination with the latest wind load provisions in ASCE/SEI 7 (ASCE 7-10) and the wind load maps are based on V ult which produces a strength level wind load similar to seismic load effects.
