Littleton Zoning Overview

Littleton is a historic city in Arapahoe County, located south of Denver along the South Platte River. Founded in 1890, Littleton features a charming downtown along Main Street that has been a model for small-town revitalization in the Denver metro area. The city's zoning code establishes traditional residential, business, and industrial districts. Littleton's land use pattern includes older single-family neighborhoods near downtown, newer suburban areas, and a historic commercial district that anchors the community.

Littleton's comprehensive plan focuses on preserving the city's small-town character while accommodating infill development and transit-oriented growth near light rail stations on the C and D Lines. The city spans the South Platte River and includes significant parks, trails, and open space along the waterway. Littleton's Historic Downtown district is subject to design review to maintain architectural compatibility.

Community Development handles planning, zoning, and building permits for the city.
