of Entrance Door.)
3. Doors opening directly from a sleeping unit or dwelling unit.
4. Doors that open directly from a space less than 3,000 square feet (298 m2) in area.

Building Code (See Building Code Section 1008.1.8). There shall be no occupancy in the
vestibule, including but not limited to, building lobby elevator lobby reception area
security area, furniture other than the occasional seat/chair etc.
The area shall be an unoccupied space used to separate conditioned space from the exterior
Providing conditioned air to the vestibule is not prohibited but the desi er may consider
limiting such conditioned air only to heating as necessary to avoid freezing or moisture
buildup.
IECC SECTION 505
*IECC Section 505.2.1; changed to read as ollows:

partitions shall have at least one manual control for the lighting serving that area. The
required controls shall be located within the area served by the controls or be a remote
switch that identifies the lights served and indicates their status.
Exceptions: The following areas need not have lighting controls:
1. Areas designated as security or emergency areas that must be continuously lighted,
inclusive of areas of incarceration.
2. Lighting in stairways or corridors that are elements of the means of egress.
*IECC Section 505.2.2.3: changed to read as follows:
505.2.2.3 Daylight zone control. Daylight zones, as defined by this code, are clarified
as follows:
19
1_. Under skylights. The area created by the width of the skyligh~lus drawing_ a 45
degree angle down to the floor below, or if the angle is blocked by an opaque wall the
distance to the wall. The area shall include s uaring off the outside edges at the corners
When skylight areas overlap, the overlap area shall be divided in half between the
sk li ts.
2. Adiacent to vertical fenestration. The area created by the width of the fenestration
plus 2 feet on each side and the depth to the next opaque wall but not more than 15 feet
Adiacent vertical fenestration areas along the same cardinal orientation may be considered
as one contiguous area unless receiving da~ight from two different angles such as in a
building corner. When vertical fenestration areas overlap skylight areas the overla area
shall be divided in half between the fenestration sources.
Daylight zones shall be provided with individual controls that control the lights
independent of general area lighting. Light fixtures shall be installed such that those
dedicated to the daylight zone shall be separate from those dedicated to the non-daylight
zones. An app~riate design method would be as thou they were independent rooms
inclusive of light reduction controls of Section 505.2.2.1. Contiguous daylight zones
adjacent to vertical fenestration are allowed to be controlled by a single controlling device
provided that they do not include zones facing more than two adjacent cardinal orientations
(i.e., north, east, south, west). Daylight zones under skylights more than 15 feet (4572 mm)
from the perimeter shall be controlled separately from daylight zones adjacent to vertical
fenestration.
Exception: Daylight spaces enclosed by walls or ceiling height partitions and
containing two or fewer light fixture are not required to have a separate switch for
general area lighting.

various retail areas but cannot be used outside of the retail floor area.
*IECC Section 505.6.2; changed to read as follox~s
20
505.6.2 Exterior building lighting power. The total exterior lighting power allowance
for all exterior building applications is the sum of the base site allowance plus the
individual allowances for areas that are to be illuminated and are permitted in Table
505.6.2(2) for the applicable lighting zone. Tradeoffs area allowed only among exterior
lighting applications listed in Table 505.6.2(2), Tradable Surfaces section. The lighting
zone for the building exterior is determined from Table 505.6.2(1), and as further detailed

the following items:
Thermal Envelope
All penetrations in the thermal envelope, including but not limited to,
electrical boxes, air duct grills, light fixtures, ceiling fans, (with ceiling 3
items such as light fixtures and ceiling fans specifically identified on the
plans) are noted as fully sealed around the edges and through the
electrical cord entry points.
(All such items must be sealed around the exterior in the space between
the item and the gypboard. Electrical boxes must have the wiring entry
hole sealed with approved material. Utility penetrations through the
envelope, including but not limited to, the exterior wall, top and bottom
plates, floor and ceilings must be sealed. Seals must also be installed
around electrical wiring through studs to separate opposite facing
27
electrical boxes in an envelope wall such as the wall separating the
garage and the conditioned space.)
Floors
a. Insulation installed to maintain permanent contact with the
underside of the subfloor decking, enveloping any attached
ductwork within the thermal envelope without compression or air 2
gaps in the insulation.
b. Batt and loose insulation is held in place by permanent attachments
or systems in accordance with the manufacturer's instructions.
Crawl space
Where insulated, insulation details noting wall insulation is permanently 2
attached to the walls. Exposed earth in unvented crawlspaces is covered

Attic access, knee wall door, or drop-down stair is covered with
insulation and gasketed. Knee wall door is an insulated unit or is 2
covered with insulation. Attic access doors are considered exterior
envelope doors. Attic access hatches shall be encapsulated with an
insulated cover.
Recessed lighting
Recessed light fixtures that penetrate the thermal envelope are noted on 2
the plans and are airtight, IC-rated, and sealed with gasket, caulk, or
foam.

Skylight shafts and knee walls are insulated to the same level as the 2
exterior walls.
Tubs and showers
Walls behind tubs and showers shall be sealed as other walls with 2
gypboard or equivalent as the remainder of the dwelling unit.
Common walls between dwelling units shall be sealed to prevent air
exchanges through the wall. This includes sealing opposing electrical 2
outlets in which air might flow through.

International Energy Conservation Code and Adopt a Corresponding Amendment to the Minimum Building
Standards Code
RECOMMENDATION:
It is recommended that the City Council:
Adopt the attached six ordinances which include the following:
1. Adoption of the 2009 International Building Code with local amendments, as the Building Code of the
City of Fort Worth;
2. Adoption of the 2009 International Residential Code with local amendments, as the Residential Code of
the City of Fort Worth;
3. Adoption of the 2009 International Mechanical Code with local amendments, as the Mechanical Code
of the City of Fort Worth;

Compliance staff and approved to be processed with this MBC.
DISCUSSION:
Construction codes are constantly changing with the development of new products, materials, construction
methods, and after-action evaluations of disasters. The City of Fort Worth has adopted model codes from
the International Code Council (ICC), with local amendments, as the construction codes for the
City. These model codes are reviewed and updated annually through a national code adoption process.
Every three years these changes are codified and published for local adoption. The 2009 edition of ICC
codes are the latest published version offered for adoption by the Planning and Development Department
and the Fire Department.

During the code review staff endeavored to identify code provisions that would most affect industry, such
as Residential Wind Bracing, State of Texas Foundation Requirements, and Window Sill Height. To further
the dialogue with the industry, notifications were distributed and meetings were held with impacted
stakeholder groups, including the Development Advisory Committee and the Greater Fort Worth Builders
Association.
The State of Texas has adopted the 2009 International Energy Conservation Code (IECC) as the energy
code for the state. As such, adoption and implementation by the City of Fort Worth is required by April 1,
2011, for commercial construction and January 1, 2012, for home construction. Staff proposes to follow
the State's effective dates.
The ordinances will have an effective date of April 1, 2011 for all provisions except home energy code
requirements which will be effective January 1, 2012.
