MEMORANDUM
June 21, 2004
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 Plumbing Code (IPC) specifies the type of plumbing materials which may be used in
the various parts of construction, as well as the method of installation. Anything attached to the water
or sewer system is regulated in the plumbing code. All of this is done to provide for safe and sanitary
systems, both initially and as the building ages. Southlake currently operates under the 2000 IPC. The
proposed ordinance will bring us up to date by adopting the 2003 edition of the International Plumbing
Code (2003 /PC). This ordinance was created from the framework of the previous ordinance, inserting
the NCTCOG recommended regional amendments.
