UtahState201120112012-07-01
 The State has also adopted the 2009 International Residential Code (IRC) in its entirety, including the electrical chapters. With the 2009 IRC containing the residential requirements from the 2005 NEC, there is inconsistency in technical requirements, as it has been determined that the electrical provisions of the IRC apply to buildings covered under that code. Therefore, a jurisdiction will enforce the 2011 NEC for apartments, condominium, and other multi-family dwellings, but revert to the 2005 NEC for one-family and two-family dwellings. The 2012 IRC is set for adoption on 7/1/2013, th AFCI issue is still open for debate as it is currently amended to only cover the language as defined in the 2005 NEC for 1 and 2 family dwellings and townhomes.The Utah Building Code web site is http://www.dopl.utah.gov/programs/ubc/.

At this stage, senators consider amendments, which may be proposed by committees and by individual senators. Many people consider General File to be the most crucial stage of the legislative process because it is where most compromises are reached. It takes a majority vote of the Legislature (25 votes) to adopt amendments or move a bill from General File to the next stage of consideration.
