Definitions
Throughout the IBC, specific terms are used in a manner that
differs from their ordinarily accepted meaning. Such terms are
necessarily defined in order to clarify their meaning within the
context of the code. In the past, these definitions have been
found in various locations throughout the IBC. For consistency
and usability purposes, all definitions have now been moved
to a single location in Chapter 2.
Note: Some definitions can still be found in various sections of
the code.

303.1
ASSEMBLY GROUP A
Where persons gather for civic, social, or religious 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.
303.3
ASSEMBLY GROUP A-2
Gaming areas are now classified as a Group A2 occupancy. The general feeling of the code
writers was the activities occurring in the gaming
areas of casinos more closely resembles those
of night clubs. There are distracting lights,
sounds, decorations, and, in many cases,
alcoholic beverages are being consumed.
Due to the various distractions, it is possible that the occupants will
become disoriented and confused in an emergency situation.
17
2014 Advanced Significant Code Changes - FBC-Building 5th Edition, Module 1
303.3, 306.2
OCCUPANCY CLASSIFICATION OF COMMERCIAL KITCHENS.
Commercial kitchens have historically been
characterized as two different types, those
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.
308.4
Occupation Classification for Medical Care Facilities
Group I-2 occupancies include those medical
care functions where the recipients receive
care on a 24-hour basis, such as nursing
homes and hospitals, where most of the care
recipients are incapable of self-preservation
and require the assistance of others under
fire or other emergency conditions.
.
18
2014 Advanced Significant Code Changes - FBC-Building 5th Edition, Module 1
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.
402
Open Mall Buildings
Although the general provisions were
intended to be applied equally to both open
mall buildings and covered mall buildings, a
number of the previous requirements did not
fully address open mall conditions.
The only new concept is the establishment of
an “open mall building perimeter line” that is to
be used to identify the boundary between
what is considered to be part of the open mall
building and what is outside of the building.
19
2014 Advanced Significant Code Changes - FBC-Building 5th Edition, Module 1
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..
403.6.1
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.
20
2014 Advanced Significant Code Changes - FBC-Building 5th Edition, Module 1
406.5.2.1
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: Openings are not required to be distributed over 40
percent of the building perimeter where the required openings are
uniformly distributed over two opposing sides of the building.
406.5.5
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.
21
2014 Advanced Significant Code Changes - FBC-Building 5th Edition, Module 1
412.4.6.2
Aircraft Hangar Fire Areas
This change allows the square
footage of ancillary spaces not
considered to be a direct part of
the aircraft servicing area to not
be included in the calculation of
the fire area.
This change reduces the
required minimum 2-hour fire
barrier to a 1-hour fire barrier.
414.5
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.
22
2014 Advanced Significant Code Changes - FBC-Building 5th Edition, Module 1
422
Ambulatory Care Facilities
In a multi-tenant or mixedoccupancy 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.
501.2
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.
23
2014 Advanced Significant Code Changes - FBC-Building 5th Edition, Module 1
505.2.2
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.
506.2
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.
24
2014 Advanced Significant Code Changes - FBC-Building 5th Edition, Module 1
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 508.2.
509
Incidental Uses – General Provisions
This change clarified the
concept of individual uses
by eliminating the previous
understanding with mixedoccupancy provisions.
Incidental uses will no
longer be separated from
building classifications

Incidental Uses – Rooms or Areas
The list of incidental uses now includes waste and linen
collection rooms in Group B ambulatory care facilities and
such rooms must be separated from the remainder of the
building by minimum 1-hour fire-resistance-rated fire barriers
and/or horizontal assemblies.’
It identifies the rooms/areas that are regulated as “Incidental
Uses” and establishes the degree of fire protection. The
intent is to provide safeguards against the increased hazard
level due to incidental use
510.4

Parking Beneath R-4
In Type 1 construction or open of Type
IV construction, with grade entrance,
is provided under a building of Group
R, the number of stories to be used in

Multiple-Use Fire Assemblies
This clarification states that when
a single fire assembly serves
multiple purposes, such as a wall
being used as a fire barrier and
partition, all requirements for both
classifications must be met.
Ex: A door in the 2 hour fire barrier
being required to meet the 1-1/2
hour fire-resistance rating and
smoke and draft criteria for a door
in a corridor wall.

Establishing Fire Resistance Ratings
This clarification states that
in order to establish a fire
resistance rating, a fire
suppression system is NOT
permitted to be included as
a part of the tested building
or materials.
703.7
Identification of Fire and Smoke Separation Walls
In order for better visibility
of markings of walls and in
above ceiling spaces, the
size and locations of
identifying markings have
been modified.
Must be located within 15
feet from the end of each
wall, at intervals not to
exceed 30 feet, and letters
3 inches high.

Risk Categories
1 OF 4
Because the term “ occupancy” relates to the nonstructural fire and life provisions, not the
risks associated with structural failure, which could pose substantial risk to the public, the
term of “occupancy category” has been changed to “risk category” to reflect the intended
meaning and to align terminology used in ASCE 7-10.
Because the term “occupancy category” occurs in so many chapters of
the code, the entire code change text is too extensive to be included here.

areas to determine the total occupant load.
b. Where approved by the building official, the classification of buildings and other
structures as Risk Category III or IV based on their quantities of toxic, highly toxic,
or explosive materials is permitted to be reduced to Occupancy Category II,
provided it can be demonstrated by a hazard assessment in accordance with
Section 1.5.3 of ASCE 7 that a release of the toxic, highly toxic, or explosive
materials is not sufficient to pose a threat to the public.

1608.3 & 1611.2
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. 1608.3 addresses this with
snow load conditions, which is not
applicable in FL. However, 1611.2
addresses the instability for rain load
conditions
Susceptible bay provisions apply solely to roofs with a slope less than 1⁄4-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 1⁄4-inch per foot or greater towards points of free
drainage is NOT a susceptible bay.
1609
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 Vult which
produces a strength level wind
load similar to seismic load
effects.
Vasd = Vult √0.6
Equation 16-33, conversion of
wind speed from Vult to Vasd
Vult = Ultimate design wind speeds.
VASD = Nominal design wind speeds.

2406.1 & 2406.4
Safety Glazing – Hazardous Locations
In order to provide more
clarity and consistency
between the Florida
Building Code - Residential
and the Florida Building
Code - Building, the
hazardous locations have
been identified in the
glazing provisions have
been reorganized.
2406.2
Safety Glazing – Impact Test
Previous references to Tables
2406.2(1) and 2406.2(2) was
provided to establish test
criteria for safety glazing.
However, it did not address all
hazardous locations. This
change revises and imposes a
more restrictive test methods.
Higher impact requirements
will apply unless the tables
allow for a lower impact test to
be used.

2510.6
Water-Resistive Barriers for Stucco Applications
In order to reduce the likelihood of
moisture getting into the building,
detailed requirements have been
provided for the installation of the two
layers of weather-resistive barriers
that are required behind stuccocovered exterior walls.
Exception: Water-resistive barrier
applied over wood-based sheathing
greater than 60 minute Grade D
Paper, separated by a non-water
absorbing layer or drainage space.
2 LAYER SYSTEM
• Each layer of
water-resistive
barrier is
individually in a
ship lapped fashion
• Interior layer
forms a continuous
drainage plan and
integrated with
flashing
2603.4.1.14
Foam Plastic Insulation Installed in Floor Assemblies
The use of ½-inch wood
structural panels installed on
the walking surface side of a
floor assembly is now permitted
as an alternative to the thermal
barrier typically required where
foam plastic insulation is
installed within a floor
assembly.
This was created as a viable
means of protecting the foam
plastic insulation.

separating foam plastic
insulation. Each of them have a
variance in the relationship to
maximum permitted flamespread and smoke-developed
rating index.
2603.10 & 2603.10.1
Special Approval of Foam Plastics
This change requires that
regardless of the test standard
used, the smoke development
of all assemblies that contain
foam plastic is evaluated.

Slope Requirements of a Dome Skylight
The minimum slope dimension
requirements of a dome skylight
have been revised.
Rise of not less than 10 % of
the width of the dome, or 3
inches.
This change was brought about
due to plastic skylights
representing a potential means
of fire spread.
2612
Fiber – Reinforced Polymer
Fiber-reinforced polymer installed on an exterior wall has been reclassified as a
required to be a Class A Flamespread material and is limited to 10% of the exterior
wall for any individual element or group of non-separated elements.
This change was done to
clarify the definition and
and eliminated the term
“fiberglass reinforced
polymer.”
