Most Colorado cities and counties accept the ICC G12, which is based on the 2018 codes, and the ICC F12, which is based on the 2015 codes. Contractor Training Center recommends confirming with your city or county that they accept either exam. If they do, CTC recommends taking the G12 because this is the most up-to-date code exam.
