About Warrenville's Building Codes
The City of Warrenville adopts building and safety codes published by nationally recognized code agencies such as the International Code Council (ICC) and the National Fire Protection Agency (NFPA) to assure structures in this community are constructed to the safest standards in the world. Specific code adoption and amendments to the adopted codes can be found in Title 8 of the City's Municipal Code.

Each amendment has sub-section numbers and title to correspond with the published version of the construction code.
