Fort Collins Zoning & Land Use Guide
Key Zoning Facts
Fort Collins Zoning Overview
Fort Collins, home to Colorado State University, is the fourth-largest city in Colorado and the economic center of Larimer County. The city uses a unique land use code (Article 4 of the Municipal Code) that combines elements of performance-based and form-based zoning rather than relying on a purely traditional Euclidean system. Fort Collins organizes its zoning into district types that describe intended development patterns, such as Low Density Mixed-Use Neighborhood (LMN) and Medium Density Mixed-Use Neighborhood (MMN), reflecting the city's emphasis on walkable, mixed-use communities.
Fort Collins has a strong tradition of proactive planning, with its City Plan comprehensive plan guiding growth along transit corridors and into established urban areas rather than sprawling outward. The city's transit system, Transfort, including the MAX Bus Rapid Transit line along Mason Street, has influenced land use patterns and spurred transit-oriented development in the downtown and midtown areas. Fort Collins is known for its high quality of life, active outdoor recreation culture, and a historic downtown that serves as a model for Main Street preservation.
Development review in Fort Collins is handled by Community Development & Neighborhood Services, which processes development plans, building permits, and land use applications through a tiered review system that ranges from administrative review to Planning and Zoning Commission hearings.
Key Zoning Districts

The Residential Low Density (RL) district covers large-lot single-family areas, while the Low Density Mixed-Use Neighborhood (LMN) allows a mix of housing types including single-family, duplexes, and townhomes. The Medium Density Mixed-Use Neighborhood (MMN) permits higher-density housing including apartments. The Downtown (D) district allows the highest density and intensity of uses. Neighborhood Commercial (NC) and Community Commercial (CC) districts serve retail and service needs at various scales.
