SUBJECT
: Ordinance No. 935, 1st Reading, adopt to the 2006 International Fuel Gas Code.
(if approved at first reading, the public hearing will be held March 4, 2008)
Purpose:
The purpose of Ordinance No. 935 is to update the Fuel Gas Code of the
City to the 2006 Edition.
Applicability:
The Fuel Gas Code applies to the installation of fuel gas piping systems,
fuel gas burning appliances, gaseous hydrogen systems and related
accessories, in the City of Southlake
Methodology:
Since 1967, the North Central Texas Council of Governments has actively
promoted the standardization of model construction codes in an effort to
simplify the construction process, advance the safety of building systems,
promote common code interpretation, facilitate the mobility of contractors,
and reduce training and construction costs.
The Regional Codes Coordinating Committee (RCCC) and its four
Advisory Boards comprised of local public and private code professionals
continually review the latest editions of the model construction codes and
recommend uniform amendments for the North Central Texas region.
The City of Southlake has representatives sitting on the various
committees participating in the regional recommendation process.
BBA
On January 24, 2008 the Building Board of Appeals met to consider the
proposed ordinances adopting the 2006 I Codes. Charles Bloomberg,
Plans Examiner and David Barnes, Fire Marshal explained the changes in
Page 1 of 16
the I Codes from 2003 to 2006. Mr. Bloomberg explained the most
significant changes; 1) Residential sprinkling to include non-living space
equaling 6,000 square feet or greater (garages and unfinished bonus
rooms). 2) New fee for unauthorized cover up during construction. 3)
Plumbing AAV (Air Admittance Valve) must be approved prior to
installation and must be marked on plans.
Discussion: Board members and Staff discussed general code
compliance.
A motion was made to recommend adoption of 2006 I Codes with local
amendments. Motion Passed unanimously.
SPIN:
On January 28, 2008, staff held a citywide SPIN meeting in Southlake
Town Hall to present the 8 ordinances in the current 2006 code package.
Explanation was given of the impact, focusing primarily on residential
construction. Questions were asked about specific applications, but no
specific objections were aired.
Action Requested
: Conduct a public hearing and make a recommendation on Ordinance No.
935, adopting the 2006 International Fuel Gas Code and certain local
amendments.

FROM: Chuck Bloomberg, Plans Examiner
SUBJECT: International Codes Update
The City of Southlake has adopted the International Code Council’s construction codes as
our local building codes with regional and local amendments. The codes are continually
updated on the national level and are published every three years. The current codes, the
2006 edition have been reviewed by the Regional Code Coordinating Committee and
Executive Council of the North Central Texas Council of Governments and recommended
for adoption by area cities.
Highlights of the proposed ordinances you may wish to include in the Council Memo are as
follows:
2006 International Building Code. This code regulates all buildings not covered by the
IRC. The administrative chapter includes our permits for grading or “earth disturbance.” The
fee section is similar to the IRC ordinance. Again the NCTCOG recommendations are
followed except for some items that are more clarification than actual code changes. We
follow the NCTCOG choice for group B cities as far as fire sprinkler options, protecting
buildings greater than 6000 square feet as we have since 1994 with some modifications.
2006 International Fire Code. This code establishes regulations affecting or relating to
structures, processes, premises and safeguards regarding: (1.) The hazard of fire and
explosion arising from the storage, handling or use of structures, materials or devices; (2.)
Conditions hazardous to life, property or public welfare in the occupancy of structures or
premises; (3.) Fire hazards in the structure or on the premises from occupancy or operation;
(4.) Matters related to the construction, extension, repair, alteration or removal of fire
suppression or alarm systems. Amendments include NCTCOG recommendations and Fire
Services recommendations.
2006 International Energy Conservation Code. This is the code mandated by state law
with specific language that we may not amend it in any way less restrictive than the original
code adopted in 2001. The law established the Energy Systems Laboratory at Texas A & M
University as the judge as to what is or is not less restrictive. ESL worked closely with
NCTCOG in making recommendations for this edition of the code.
Attachment A

2006 ICC Electrical Code Administrative Provisions. This code adopts the 2008
National Electrical Code by reference as written without amendments and also gives the
administrative provisions consistent with the other
International Codes.
• 2006 International Plumbing Code. This code regulates plumbing systems including
water and sewage and storm sewer piping systems and their fixtures. The Plumbing
ordinance limits amendments to those recommended by NCTCOG.
• 2006 International Fuel Gas Code. This code regulates gas piping, fuel burning
appliances and their vents. Again amendments are limited to the NCTCOG
recommendations.
• 2006 International Mechanical Code. This code regulates Heating, Air Conditioning and
mechanical ventilation systems. The NCTCOG amendments have been recommended for
the IMC.
• 2006 International Residential Code. This code regulates one and two-family dwellings
and townhouses not over three stories high and their accessory structures. The IRC is
unique in that one book covers all construction for dwellings including building, electrical,
plumbing, energy conservation, plumbing, heating and air conditioning and fuel gas piping.
Other than in the administrative chapter and appendix chapters the amendments are as
recommended by NCTCOG. In section 108.8 an unauthorized cover up fee was added to
help get final inspections on swimming pools prior to filling them. The energy code
provisions were revised by ICC and therefore had to be amended to remain in compliance
with state law. The residential sprinkler requirements were changed as recommended by
Fire Services.
