Centennial Zoning Overview

Centennial is one of Colorado's newest cities, incorporated in 2001 as a primarily residential community in Arapahoe County south of Denver. The city was formed largely to provide local governance and preserve the suburban character of established neighborhoods. Centennial's zoning code, adopted upon incorporation and based largely on former Arapahoe County zoning, establishes traditional residential, commercial, and industrial districts. The city is almost entirely built out, so most development activity involves redevelopment, infill, and renovation rather than greenfield construction.

Centennial's comprehensive plan emphasizes maintaining the quality of its residential neighborhoods while supporting revitalization of aging commercial areas, particularly along Arapahoe Road and Parker Road. The city's light rail access via RTD's E and H Lines connects Centennial to downtown Denver and the Denver Tech Center, influencing land use patterns near stations. Centennial is notable for its extensive HOA coverage -- a significant majority of residential properties are within homeowner associations that impose additional development restrictions beyond city zoning.

Community Development handles planning, zoning, and building permit functions. Building permits and inspections are provided through a contract with Arapahoe County or third-party service providers.

Key Zoning Districts

Centennial's zoning includes R-1 (Single-Family, 9,000 sq ft lots) through R-4 (High-Density Residential), commercial districts C-1 and C-2, and industrial districts. Planned Development districts cover several master-planned communities. The city has been exploring Mixed Use zoning for certain commercial corridors.

ADU Regulations

Centennial allows ADUs in residential zones under Colorado HB 24-1152. ADUs are limited to 800 square feet and 20 feet in height. No additional parking is required, and owner-occupancy is not mandated. Building permits are reviewed within four to six weeks.

Development Process

Centennial's development process includes administrative review for by-right projects and Planning Commission hearings for rezonings and special uses. Building permits are processed through the city's contracted building services provider, typically within four to six weeks for residential projects.
