ZIP code 80228 covers western Lakewood and the Denver Federal Center area, situated at the gateway to the Rocky Mountain foothills. This ZIP code offers a unique mix of government employment centers, suburban housing, and direct access to mountain recreation.
The Denver Federal Center, a 670-acre campus housing over 28 federal agencies and approximately 6,000 employees, is the largest federal complex outside Washington, D.C. and anchors the employment base of 80228. Agencies including the U.S. Geological Survey, the Bureau of Reclamation, and the National Renewable Energy Laboratory (NREL) maintain major facilities here. The residential areas within 80228 offer spacious mid-century and newer homes, many on larger lots than comparable Denver properties, with some properties backing up to open space or creek corridors. Union Boulevard and Kipling Street serve as the primary commercial corridors, offering retail, dining, and professional services. Green Mountain, a 2,400-foot mesa rising 6,800 feet above sea level, offers miles of hiking and mountain biking trails with spectacular 360-degree views of Denver, the Continental Divide, and the eastern plains. The William F. Hayden Park trail system on Green Mountain is one of the most popular hiking destinations in the Denver metro area.
80228's combination of government employment stability, mountain-adjacent living, and suburban space makes it particularly attractive to federal employees, outdoor enthusiasts, and families seeking Jefferson County schools. Median home values are competitive with other western suburb ZIP codes, offering more land and mountain proximity than comparable price points in Denver proper. The ongoing expansion of light rail and bus service continues to improve transit connectivity, reducing the area's historical car-dependence.
