2022 Building and Fire Code and Denver Green Code Adoption Process

These baseline amendments incorporate the 2021 model I-code language plus any current (2019) Denver code amendment provisions that are more stringent then, additive to, or in disagreement with the 2021 model I-Code language. It also includes grammatical and errata revisions, such as incorrect cross references or typos. The only variation to the previous statement is that the ‘baseline’ of the 2021 DGC is the 2019 DGC (not the 2021 IgCC).
