Recreational & Residential Land for Sale in Boulder, Colorado

A once-in-a-lifetime opportunity to own a piece of the legendary West. For the first time in nearly 150 years, Hogan Ranch-450 acres of pristine Colorado wilderness-offers three 35-acre parcels: Joann's Reserve, Chris' Reserve, and Coal Creek Reserve. Held by the same family for seven generations, this land is steeped in history, beauty, and western spirit. Just off Highway 93, each parcel is accessed via a private, resident-only road and was hand-selected for its exceptional privacy, premier buildability, and sweeping, unobstructed views of the iconic Flatiron Foothills. With no neighboring structures and borders that adjoin permanently protected City of Boulder open space, these Legacy Estates offer unmatched seclusion and a direct connection to public trailheads, wildlife habitats, and celebrated landscapes. Joann's Reserve crowns the northwest mesa with a 5-acre buildable envelope and offers stunning views of the Flatirons, Doudy Draw, and Boulder's mountain parks. Within the envelope, owners may build a single-family residence and two accessory structures such as a detached garage, greenhouse, barn, or corral. Recreational amenities-a pool with cabanas, tennis or basketball court-are also permitted. The residence may include a separate apartment Accessory Dwelling Unit (ADU) as part of the residential structure; not a separate structure, for use by a caretaker or family member. Accessory structures may not exceed a combined 6,000 square feet. There is no limitation on the size of the primary residence. All structures are restricted to a maximum roof height of thirty (30) feet. Owners can design expansive living spaces with soaring ceilings, walk-out basements, and architecture that frames the panoramic views. Owned by the same family since 1876, Hogan Ranch embodies history, solitude, and unspoiled beauty-more than land, it is a legacy.
