Building Codes

2012 and 2018 International Codes® 

The 2018 family of International Codes® took effect in Commerce City on December 4, 2019 (except the 2018 International Residential Code, which takes effect on May 4, 2020). The 2018 codes replace the 2012 family of International Codes®, which had been in place in the city since June 6, 2016.

Due to the transition to the updated codes, the city will allow a six-month grace period from the effective date of December 4, 2019 to allow builders to comply with the 2018 codes. Builders must comply with the 2018 codes by June 4, 2020.

These codes establish minimum requirements to safeguard the public health, safety, and general welfare through structural strength, means of egress, stability, sanitation, adequate light and ventilation, energy conservation, and safety of life and property from fire and other hazards attributed to the built environment. These codes also provide safety to fire fighters and emergency responders during emergency operations. 

The City of Commerce City has amended various adopted codes in order to address conditions unique to the city (the city's 2018 code amendments will be posted online soon - call the Building Safety Division at 303-289-3790 with questions until then):
