About This Property

Rare Boulder development opportunity: 0.76 acres in North Boulder's Crestview West neighborhood with both immediate livability and remarkable buildout potential. Under the city's 2025 transit corridor zoning reforms, this RR-1 parcel qualifies for a duplex or two single-family residences on the same lot - no subdivision required. Generous FAR (6,593 sq ft above-grade) plus full basements excluded from FAR calculations yield ~10,000+ sq ft of total livable space across two units, plus a 500 sq ft accessory structure. Set against a backdrop of unobstructed, permanent Flatiron views, the property features mature trees, fruit plantings, rich agricultural soil, and lush grounds, creating a private, park-like setting. The property includes one share of water from the Silver Lake Ditch - a rare allocation within city limits. The existing four-bedroom, three-bath home offers 2,346 sq ft of living space with tongue-and-groove ceilings, exposed beams, large windows framing the landscape, and a cozy wood-burning stove. An extensive due diligence package is available, including annexation agreement, survey, city correspondence, and a step-by-step development guide. The majority of the lot falls within the 500-year floodplain, which carries minimal regulatory restrictions; additional floodplain considerations apply - see buyer materials. A pre-application meeting with the City is recommended as a first step. Ideally located near Wonderland Lake, open space, trails and Downtown Boulder, this is a singular opportunity to craft an extraordinary vision on one of North Boulder's most compelling parcels.
