Gilpin County, located in the Front Range west of Denver, is small and mountainous, with towns such as Central City and Black Hawk, known historically for gold mining and gambling. Housing tends to include historic homes in the mountain towns, small-lot homes, and homes on larger parcels outside town in forested areas. Because of its limited size and mountainous terrain, land is less plentiful and build-sites may involve higher costs. Existing home purchase prices can range from US$450,000-700,000+ depending on location and condition; building might cost US$300-400 per sq ft or more where access or elevation is challenging. The area is more rural/mountain, yet is relatively near to the largest city (Denver) — being ~30–45 minutes away in good traffic — which gives it commuter-town potential.
