Residential Land for Sale in Longmont, Colorado
339 17th Ave, Longmont, CO 80501
Rare opportunity to secure a prime oversized 12,188 sq ft corner lot in one of Longmont’s established and centrally located neighborhoods. Zoned Mixed Residential, this property offers outstanding potential for builders, developers, investors, or buyers looking to create a one-of-a-kind custom project. With the possibility to subdivide into up to four 4,000 sq ft lots (buyer to verify with city), the development opportunities are substantial.
The property which includes an existing home which was built in 1910 is being sold as improved land and will require a full demolition, making this an ideal blank canvas for redevelopment. Active water, sewer, and power taps are already in place, providing valuable infrastructure savings and added convenience for future construction. Alley access enhances flexibility for site planning, parking, garages, or additional access points.
Mature trees throughout the property provide charm, privacy, and established character rarely found on redevelopment lots. Located close to Main Street, the property offers easy access to local restaurants, shopping, markets, parks, and everyday amenities.
Whether you envision multiple new builds, an investment project, or a custom residence on a large in-town lot, this property presents an exceptional opportunity in a highly desirable Longmont location. Property sold strictly as-is. Buyer to verify all zoning, subdivision, redevelopment, and building possibilities.
