BACKGROUND INFORMATION: The 77th Legislature recently passed SB 365, adopting the 2000 International Residential Code (IRC) as the municipal residential building code in Texas. The State adoption of this code is the result of lobbying and support by builders associations, architects, and others. Unlike our other codes, this is a stand-alone document, with building, plumbing, mechanical and electrical provisions contained within. This legislation allows cities to review and adopt amendments to the IRC, and does not require cities to adopt or enforce the electrical provisions of the code. It is staffs intent to delete the electrical provisions, and defer to the currently adopted electrical code (1996 National Electrical Code). The IRC will replace the 1994 Uniform Building Code, 1994 Uniform Mechanical Code, and 1991 Uniform Plumbing Code for one and two familv dwellings and multi -family structures with orooertv lines between units three stories or less in height with seocrate means of eawress and their accessory structures only. Enclosed are amendments relative to the adoption of the code, and amendments to the code itself (most of which are recommended by the North Central Texas Council of Governments). Staff will cover the major amendments and the most important changes between the current codes and the IRC at the public hearing. It is the intent of the Building Department to forward to City Council the ordinance adopting the IRC and its amendments by January 2002. As this is a draft ordinance, it is subject to administrative and editorial changes. Staff recommends the Board review the ordinance and recommend adoption based on this understanding. 0ABBA0111.4 News and Information for the Texas Building Officials, Inspectors, and Industry Officials • Summer 2001 TEXAS ADOPTS THE INTERNATIONAL RESIDENTIAL CODE Austin, TX - Governor Rick Perry of Texas signed a bill to adopt the International Residential Code as the municipal residential building code for the state of Texas. The bill goes into effect on September 1, 2001, and gives cities until January 1, 2002, to tran- sition and begin enforcing the new code. Senator Ken Armbrister (D) of Victoria, introduced the bill (SB365). Representative Allan Ritter (D) of Nederland, a member of the Texas Association of Builders (TAB), carried the bill through the House. or The bill adopts the International Residential Code for one -and two- family dwellings as it existed on May 1, 2001. It provides municipalities with the authority to adopt local amendments to the code, establish procedures for the administration and enforcement of the code, and review and consider amendments and new editions of the code. This is the first.statewide residential build- ing code in Texas. The effort to adopt the International Residential Code was led by the Texas Association of Builders (TAB). Nancy Fisher, a lobbyist for TAB, led the support effort that was crucial to the passing of the bill. TAB and ICUs member organi- zations in Texas worked together in a cooperative, coordinated effort to share information and resources. I believe that the adoption of the International Residential Code will improve the homebuilding indus- try in Texas. The use of a single code throughout the state will lead to consistent code enforce- ment, higher quality construction, and less confusion in the con- struction process. I believe this bill will result in more affordable and safer homes. fir Rep. Ritter Other organizations that supported the bill included the Texas Municipal League, the Texas Society of Architects, the Capitol Area Building Officials Association, the Greater Houston Builders Association, the Hispanic Contractors Association, the Texas Apartment Association, the National Association of Home Builders, as well as members of the insurance industry and other homebuilders and building officials from around the state. The principles of all the International Codes are based on protec- tion of public health, safety, and welfare. The International Residential Code for one- and two-family dwellings addresses the design and construction of one -and two-family dwellings and townhous- es. The International Codes result in efficient designs that provide flexibil- ity for the code official, designer, engineer, plumber, and architect.

November 19, 2001 Dear Contractor, RE: ADOPTION OF 2000 INTERNATIONAL RESIDENTIAL CODE On November 26, 2001, a draft ordinance adopting the 2000 International Residential Code (with amendments) will be considered by the Grapevine Building Board of Appeals. On December 4, 2001, this ordinance will be considered by the Grapevine City Council. In accordance with State Law, this code will go into effect January 1, 2002. You are welcome to attend either or both public hearings. Additionally, copies of the ordinance (or the portions pertaining to your trade) are available at the Building Inspection office. If you have any questions regarding the public hearings, the code, or ordinance, do not hesitate to contact Scott Williams, Building Official, at 817-410-3158.

Local handrail amendment requires handrail to be between 1 '/4" and 2 %z inches in diameter. 1994 Uniform Building Code, and 1994 Uniform Mechanical Code have no energy efficiency provisions. Section 302, 1994 Uniform Building Code requires one -hour construction on the garage side, and a self - closing door. 1991 Uniform Plumbing Code, Section 501 requires vents for each plumbing fixture (with some exceptions) 1991 Uniform Building Code, Section 1213 prohibits gas lines in the slab. 0:1SMIRCMAJ ORCHANGES 112601 IRC International Residential Code is a stand alone code with all provisions contained within. R321.2 Now allows a single 2-hour wall. Sections R314 and R315 requires stairs to have maximum 7 W in height with a minimum tread depth of 10". Handrails must have diameter between 1 114" and 2 5/8". Chapter 11 of the International Residential Code contains provisions for energy efficiency. Section 309 allows %2" gypsum board on the garage side, and does not require self -closing doors. Chapter 31 allows common venting, wet venting, and the use of air admittance valves. Section G2414 allows pipe to be installed in a vented conduit within slab. MAJOR AMENDMENTS TO 2000 INTERNATIONAL RESIDENTIAL CODE Sec. 105.3.2 Time Limitation of Application — limits number of extensions. Sec. 105.5 Expiration requires projects to be completed in a timely manner. R302.1.2 Exterior walls allows zero lot line homes to have non fire rated exterior walls, and allows openings adjacent to the property line. R902.1 requires minimum Class "C" fire retardant roofing materials in all cases. Sec. N1101.2 requires permit applicants to demonstrate compliance with energy provisions of the code. Sec. G2403 prohibits unvented gas equipment. Sec. G2413.5.3. Corrugated stainless steel tubing is amended to incorporate existing safety procedures. Chapter 37, Wiring Methods is deleted, and refers to the current electric code (1996 National Electric Code) OAsMI RCMAJORAMEND1101 ITEM ---� TO: HONORABLE MAYOR AND CITY COUNCIL MEMBERS FROM: ROGER NELSON, CITY MANAGER g MEETING DATE: DECEMBER 4, 2001 SUBJECT: ADOPTION OF THE 2000 INTERNATIONAL RESIDENTIAL CODE RECOMMENDATION: The Building Board of Appeals and Staff recommends Council adopt the enclosed ordinance relative to the 2000 International Residential Code and take any necessary action. BACKGROUND INFORMATION: The 77th Legislature recently passed SB 365, adopting the 2000 International Residential Code (IRC) as the municipal residential building code in Texas. The State adoption of this code is the result of lobbying and support by builders associations, architects, and others. Unlike our other codes, this is a stand-alone document, with building, plumbing, mechanical and electrical provisions contained within. This legislation allows cities to review and adopt amendments to the IRC, and does not require cities to adopt or enforce the electrical provisions of the code. The proposed ordinance amendment deletes the electrical provisions, and defers to the currently adopted Grapevine electrical code (1996 National Electrical Code). The IRC will replace the 1994 Uniform Building Code, 1994 Uniform Mechanical Code, and 1991 Uniform Plumbing Code for one and two family dwellings and multi-familv structures with orODertv lines between units three stories or less in height with separate means of egress and their accessory structures only. Enclosed are amendments relative to the adoption of the code, and amendments to the code itself (most of which are recommended by the North Central Texas Council of Governments). Many amendments simply place provisions that were in our existing ordinances under the International Residential Code (examples include minimum class "C" fire retardant roofs, non fire -rated exterior walls for zero lot line homes, and fees). Major amendments to the code itself include the prohibition of unvented gas appliances, protection from freezing for water lines, and prohibition of potentially unsanitary plumbing practices. At its November 26th meeting, the Building Board of Appeals reviewed this ordinance and code, and forwarded a recommendation of approval to Council. /ga 0ABBA0111 AA AGENDA MEMO SIGN -OFF SHEET MEETING DATE: DECEMBER 4, 2001 SUBJECT: ADOPTION OF THE 2000 INTERNATIONAL RESIDENTIAL CODE I have read and approve the attached agenda memo referenced above.
