Proposed 2018 Building Codes to Take Effect January 1, 2019

As part of a triennial process of adopting the most current building codes, the Larimer County Building Division is proposing adoption of the 2018 International Codes with local amendments, to replace our 2015 codes.  Developed with the help of a public-private Code Review Committee, the code amendments are going to be heard by the Planning Commission and Board of County Commissioners this Fall, and are proposed to take effect January 1, 2019.  If you have questions, comments or concerns, contact Building Official Eric Fried at or 498-7705.
