How Colorado adopts the IBC
For state buildings the State Buildings Program updates its policy exhibit when it approves a new edition. Local governments adopt their own building codes by ordinance or resolution, with no state review of the edition for IBC or IRC.
Cycle. Irregular for the state; local jurisdictions follow the ICC cycle at their own pace.
