Building Codes

The City of Naperville has adopted the 2012 edition of the International Codes published by the International Code Council for residential, commercial and multi-family construction. The City has also adopted amendments to 2012 International Codes, which can be found in Title 5 of the Municipal Code.

2018 International Building Code Update

Over the course of 2018, the City of Naperville will be undertaking a process to update the family of building codes that the City currently utilizes to the 2018 International Building Code (IBC) standards. These building codes were last updated in 2012.

Because building codes are ever evolving to keep pace with new technology, materials and trends in the building industry, it is recommended to review and adopt the latest codes on a regular basis to ensure continued quality and safe construction. 

The code review began in January 2018 and is expected to conclude with City Council adoption in late 2018. 

City staff organized committees to review the new code provisions, identify and discuss significant code changes, and make recommendations. Each code committee included city staff, as well as representatives from the business, building, and residential community, depending upon the code section being evaluated.
