Published zoning research
Municipal zoning overview
Denver uses a citywide zoning system centered on the Denver Zoning Code, adopted in 2010, with some properties still regulated under Former Chapter 59 if they were not brought into the 2010 comprehensive update. The code organizes zoning by neighborhood context, building type, and either minimum lot size or maximum height, so zone names carry a lot of regulatory meaning. Denver also has active permitting, Planning Board, and Board of Adjustment processes that affect how projects move from zoning analysis to approvals.
