Denver Zoning & Land Use Guide
Key Zoning Facts
Denver operates under a form-based zoning code adopted in 2010 that replaced the city's previous Euclidean zoning system. As a consolidated city-county, Denver manages all planning and land use functions through a single government. The Denver Zoning Code organizes the city into neighborhood contexts -- Suburban, Urban Edge, Urban, General Urban, and Downtown -- each with building form standards tailored to the area's character. This approach emphasizes the physical form of buildings rather than strictly separating land uses, allowing for more mixed-use development in appropriate locations.
Denver's rapid population growth over the past two decades has driven significant development activity, particularly along transit corridors served by RTD's light rail and bus rapid transit system. The city's Blueprint Denver comprehensive plan guides long-range land use decisions and has been updated to encourage growth in centers and corridors while preserving the character of established residential neighborhoods. Denver has also adopted an Expanding Housing Affordability policy framework that includes incentive zoning, inclusionary housing requirements in certain areas, and streamlined ADU permitting.
The city's zoning administration is handled by Community Planning and Development, which processes building permits, zoning permits, site development plans, and zoning variances. Denver's development review process includes both administrative approvals for by-right projects and public hearing processes for rezonings, planned unit developments, and certain conditional uses.
Key Zoning Districts
Denver's zoning code is organized around neighborhood contexts rather than traditional use-based categories. The Single Unit (SU) zone district covers the majority of Denver's residential land area and permits detached houses on lots typically ranging from 6,000 to 9,000 square feet. The Two Unit (TU) district allows duplexes and paired homes. Multi Unit (MU) districts accommodate townhomes, apartments, and condominiums at varying densities. Mixed Use (MX) districts are mapped along commercial corridors and near transit stations, permitting a combination of residential, retail, and office uses with building heights typically ranging from 45 to 75 feet.
ADU Regulations
Denver permits accessory dwelling units in most residential zone districts, consistent with both local policy and Colorado's HB 24-1152. ADUs may be attached to or detached from the primary structure, with a maximum size of 1,000 square feet. Detached ADUs are limited to 24 feet in height. Denver does not require additional off-street parking for ADUs, and owner-occupancy requirements have been removed. The city processes ADU permits administratively, with typical review times of four to eight weeks.
Development Process
Denver's development process begins with a zoning verification to confirm permitted uses and standards for a property. By-right projects that comply with existing zoning require only a building permit, which is reviewed by Community Planning and Development. Projects requiring a rezoning must go through a public process involving the Denver Planning Board and City Council. The city also requires site development plan review for larger commercial and multi-family projects. Denver's development services are largely available online through the city's eTRAKiT and Accela permitting systems.
