Item 7DCity of Southlake, Texas MEMORANDUM July 14, 2004 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. Supporting Documents: Detailed memorandum to Garland Wilson dated June 21, 2004 Ordinance No. 871, 2003 International Fuel Gas Code Billy Campbell July 14, 2004 Page 2 Staff Recommendation: Approve Ordinance No. 871 on second reading with an effective date of September 30, 2004. This is intended to provide builders time to factor changes into contracts being developed. RB /gw City of Southlake, Texas 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 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. 2003 International Fuel Gas Code ORDINANCE NO. 871 AN ORDINANCE ADOPTING THE INTERNATIONAL FUEL GAS CODE, 2003 EDITION; PROVIDING FOR THE ADOPTION OF LOCAL AMENDMENTS THERETO; PROVIDING FOR RECORDING OF SUCH CODE AS A PUBLIC RECORD; PROVIDING THAT THIS ORDINANCE SHALL BE CUMULATIVE OF ALL ORDINANCES; PROVIDING A SEVERABILITY CLAUSE; PROVIDING A SAVINGS CLAUSE; PROVIDING FOR PUBLICATION IN PAMPHLET FORM; PROVIDING FOR PUBLICATION IN THE OFFICIAL NEWSPAPER; AND PROVIDING AN EFFECTIVE DATE.

Their review and recommendations were completed and endorsed by NCTCOG's Executive Board in March 2004.

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.
