Zoning Essentials
Binding city zoning regulations from Denver Community Planning and Development allow ADUs citywide in residential zones, with max 800 sq ft floor area, min 3 ft side/rear setbacks, 18 ft height limits, and parking exemptions. ADUs stay accessory to the primary residence; additions expand the main structure without separate kitchens unless zoned as ADU.
Avoid pitfalls like non-conforming lots or historic restrictions. Schedule pre-application meetings and verify eligibility on Denver’s zoning map tool.
