Earlier this year, the International Code Council (ICC) updated its model codes, commonly referred to as I-codes. ICC intends for the latest edition of the I-codes to be adopted by jurisdictions beginning in 2012. Because these new editions contain numerous roofing-related changes, you should pay close attention to the 2012 I-codes.
Currently, the I-codes consist of 13 model codes addressing a variety of regulatory topics. Most roofing professionals are most familiar with ICC's International Building Code (IBC), International Residential Code for One- and Two-Family Dwellings (IRC), and International Energy Conservation Code (IECC), which address most buildings and structures, one- and two-family residential buildings, and buildings' minimum thermal insulation requirements, respectively. Other I-codes address topics such as fire prevention, plumbing, mechanical systems and building site zoning.
I-codes are published on a three-year cycle. For example, the IBC and IRC initially were published in 2000 and revised editions were published in 2003, 2006 and 2009.
