Denver Zoning Code Amendments and 332-Day Permit Reviews Shape Local Development Timeline

The Denver City Council approved more than 130 amendments to the Denver Zoning Code on February 25, 2025. The changes streamline requirements, remove parking minimums in Lower Downtown, and simplify standards for minor detached structures. These updates to the code adopted in 2010 now govern most development applications submitted after that date.

Properties still under Former Chapter 59

Downtown, LoDo, Stapleton, and Cherry Creek remain under Former Chapter 59 of the Denver Revised Municipal Code because they were not included in the 2010 comprehensive update. Residents and property owners in these areas continue to follow the earlier rules while new applications elsewhere move under the amended Denver Zoning Code.

Recent updates to carriage lot rules allow these lots to be developed into single-unit dwellings. Owners no longer need to reside on the block or obtain a personal zoning permit. This change directly affects homeowners considering additions or new units on qualifying lots in neighborhoods covered by the Denver Zoning Code.

Permit review timeline for residents

The average permit review time for major residential projects, including additions and custom homes, stands at approximately 332 days. Projects submitted after the February 25, 2025 amendments will be reviewed under the updated standards, so residents can expect decisions to reflect the new carriage lot provisions and simplified detached structure rules once reviews conclude.

Applications already in process before the amendments continue under prior requirements. The 332-day average means that visible changes to approved projects, such as new carriage lot dwellings or structures built without previous parking minimums in Lower Downtown, will appear gradually as reviews finish and construction begins.

City agencies continue to process zoning permits under the Denver Zoning Code for most neighborhoods. Residents seeking to build or modify property can review current requirements through the Community Planning and Development department to determine which set of rules applies to their specific location and project type.
