TO: Billy Campbell, City Manager
FROM: Rick Black, Director of Public Safety (Ext. 2421)
SUBJECT: Ordinance No. 871, 2nd Reading, Adoption of the 2003 International Fuel Gas
Code.
Action Requested: City Council approval of Ordinance No. 871 adopting the 2003 International
Fuel Gas Code with local amendments.
Background
Information: The city currently operates under the 2000 editions of the International Codes
and under the 1999 edition of the National Electrical Code. These codes are
published on a three year cycle. The North Central Texas Council of
Governments Executive Board with the recommendation of the Regional
Code Coordinating Committee has recommended adoption of these codes
except the Property Maintenance Code be adopted with regional amendments.
The Property Maintenance Code is included as an update for the Dangerous
Building Code.
Financial
Considerations: These updated codes will have nominal impact on the cost of construction in
the city.
Financial Impact: This will have no financial impact on the city budget.
Citizen Input/
Board Review: The Building Board of Appeals held three public hearings and unanimously
recommended adoption of these codes. Two additional meetings were held to
receive input from the area building contractors.
Legal Review: This ordinance has been reviewed by the city attorney and changes have been
made as recommended.
Alternatives: Adopt the ordinance as recommended or direct staff to restudy any specific
issues that may be of concern.

TO: Garland Wilson, Chief of Administrative Services
FROM: Paul Ward, Building Official, and;
Chuck Bloomberg, Plans Examiner
SUBJECT: 2003 International Codes
The ICC, International Code Council, is a nonprofit organization founded in 1994 to develop a single
set of comprehensive and coordinated national model construction codes for use throughout the
country.
We as the City of Southlake have been involved and supportive throughout the code development
process and the creation of the International Codes. This support has been through the North Texas
chapter of the International Code Council and through the regional review process be the Regional
Codes Coordinating Committee of the NCTCOG (North Central Texas Council of Governments).
The I Codes were developed with the support of many organizations that have interest in the
construction industry although the final vote on all items is by code officials only. Work on the
International Codes has been a model of democracy, without territorial disparities getting in the way.
The American Institute of Architects and the National Association of Home Builders were both very
active participants in the code development process. The National Association of Home Builders has
applauded the recent action by the International Code Council (ICC) to add "affordability" to the
Purpose Statement section of the International Residential Code (IRC), which applies to one- and
two - family homes.
The City of Southlake has had a track record of supporting the latest edition of the codes. The code
has been published every three years for a long time. Since the 1980's Southlake has adopted the
new code within one year of it becoming available.
Another important reason to be up to date with the latest codes is the ISO insurance rating. Their
system will subtract points if the city is not on the current codes. We always need to be able to show
that we are current with the latest codes.
The Building Codes are a set of universally accepted standards adopted as guidelines for
construction of buildings and related building operations. The term "building codes" is a generic phase
that actually encompasses several individual codes, each of which must be approved and adopted by
the City Council before they can be applied or enforced. These codes are periodically updated,
primarily due to new products entering the marketplace, and minor revisions may be made under the
term "local amendments."
The International Fuel Gas Code (IFGC) provides standards for fuel burning appliances and the
piping systems for them. The code also has requirements for appropriate fresh air and exhaust
ventilation necessary for safe operation. The Texas Plumbing License Law provides that only state
licensed plumbers may install or alter gas piping other than certain very specific exceptions.
Southlake currently operates under the 2000 IFGC. The proposed ordinance will bring us up to date
by adopting the 2003 edition of the International Fuel Gas Code (2003 IFGC). This ordinance was
created from the framework of the previous ordinance, inserting the NCTCOG recommended regional
amendments.

Committee (RCCC) and its four advisory boards conducted 26 open review meetings over a 10-

amendments. Their review and recommendations were completed and endorsed by NCTCOG's
Executive Board in March 2004. Now NCTCOG encourages jurisdictions in North Central Texas to
adopt the 2003 International Fuel Gas Code along with its respective regional amendments with an
effective date of July 1, 2004:

greater than 12- inches from the center of the valve. Supports shall be installed so as not to interfere with the free
expansion and contraction of the system's piping, fittings, and valves between anchors. All valves and supports shall
be designed and installed so they will not be disengaged by movement of the supporting piping.
(Reason: To provide proper security to CSST valves. These standards were established in this region in

each 45 degree (0.79 rad) bend and 5 feet (1524 mm) for each 90 degree (1.6 rad) bend.
Exceptions:
1. Where the make and model of the clothes dryer to be installed is known and the manufacturer's installation
instructions for such dryer are provided to the code official, the maximum length of the exhaust duct, including
any transition duct, shall be permitted to be in accordance with the dryer manufacturer's installation
instructions.
2. Where the first 9 feet of vent are 4" diameter pipe with not over two 90 bends and the pipe size is then
increased to 5" diameter, it may extend horizontally as far as 28.5 feet to the termination outdoors.
(Reason: Engineered dryer vent equivalent considering velocity and pressure drop.)
* *Section 621.2; change to read as follows:
621.2 Prohibited use. One or more unvented room heaters shall not be used as the sole source of comfort heating in
a dwelling unit.
Exception: Existing approved unvented heaters may continue to be used in dwelling units, in accordance with
the code provisions in effect when installed, when approved by the Code Official unless an unsafe condition is
determined to exist as described in Section 108.7.
(Reason: Gives code official discretion.)
* *Section 624.1.1; change to read as follows:
624.1.1 Installation requirements. The requirements for water heaters relative to access, sizing, relief valves, drain
