Rare 7,020 SF U-TU-C redevelopment opportunity in the heart of Sunnyside! Whether you're a builder searching for your next duplex project or a buyer looking to renovate and build equity over time, this property offers exceptional potential in one of Denver's most desirable infill neighborhoods. The existing 1901 home is being offered primarily for its land value and redevelopment potential. The oversized lot and U-TU-C zoning create an outstanding opportunity for a luxury duplex or other permitted residential development (buyer to verify all zoning, building envelope, setbacks, utilities, and development requirements with the City and County of Denver).
Builders will appreciate the generous lot size, strong surrounding redevelopment activity, and convenient access to Downtown, LoHi, Highlands, I-70, and I-25. Existing improvements may also provide value as an interim rental or renovation project while future plans are developed. Opportunities to acquire lots of this size in Sunnyside are increasingly uncommon. Don't miss your chance to secure one of northwest Denver's most compelling redevelopment sites.
