Community Planning and Development reviews, permits, and inspects building projects to ensure that what's built in Denver meets the Denver Building and Fire Code, zoning code, and related regulations. Permits are required for most construction, alteration, or repair work on private property. 

2025 Building and Fire Code is Now Effective

On June 13, 2025, the City and County of Denver adopted the 2025 Building and Fire Codes, which incorporate the 2024 I-codes (except the Energy Code, which incorporates the 2021 IECC). Updates to these codes resulting in the second printing were adopted on November 24, 2025.

The 2025 Denver Building and Fire Codes became effective December 31, 2025 and all construction drawings for new projects submitted after that date must use these codes. There are No Exceptions.
