The following sections, paragraphs, and sentences of the 2012 International Residential Code are hereby amended as follows: Standard type is text from the IRC. Underlined type is text inserted. Lined through type is deleted text from IRC. A double asterisk at the beginning of a section identifies an amendment carried over from the 2009 edition of the code and a triple asterisk identifies a new or revised amendment with the 2012 code. Note: Historically NCTCOG has limited Chapter 1 amendments in order to allow each city to insert their local policies and procedures. We now have suggested certain items to be brought to the attention of cities considering adoption of the code that may be of concern to several Ordinance 711 Page 15 of 47 jurisdictions. It is still intended to be discretionary to each city to determine which Chapter 1 amendments to include. The energy provisions in Chapter 11 of the International Residential Code (IRC) now mirror the requirements of the International Energy Conservation Code (IECC). As such, there is no difference between Chapter 11 of the 2012 IRC and the 2012 IECC. Reference the 2012 IECC for NCTCOG recommended amendments to that code.
