    2018 CODE ADOPTION MEETINGS
    The City is preparing to adopt the 2018 editions of the International Code Council construction codes. Historically, the adopted codes have been amended to reflect earlier editions to minimize construction process changes. This adoption will be somewhat different in that we intend to adopt the 2018 code editions with minimal amendments. Plans Review and Inspections Staff have been reviewing the 2018 codes the past six months. Public meetings were held July 30-August 2 from 6-7:30 p.m. at the Public Works Service Center on 3131 Morris Avenue to provide more information about the changes for each code.
