About This Home

As of April 2026

Ideally situated just moments from a vibrant downtown filled with boutique shops, a lively farmer’s market, acclaimed restaurants, and local microbreweries, this exceptional property offers a rare blend of location, versatility, and enduring character. Set on a single lot are two distinct residences that create an inviting opportunity for multi-generational living, rental income, or a private guest retreat—all within close proximity to the energy and convenience of downtown life. The primary residence began its life as a 1920s Craftsman and was thoughtfully rebuilt from the ground up in 2006, seamlessly blending classic architectural roots with modern design and functionality. Spanning 2,460 square feet, the home has been meticulously maintained and reflects the pride of ownership that comes from being cared for by the same family for three generations. Its contemporary layout and quality construction provide comfortable, refined living spaces ideal for today’s lifestyle. Tucked behind the main home is a charming, fully self-contained one-bedroom, one-bathroom cottage originally built around 1925. With its own gas, electric, and water meters, the cottage functions independently—making it an ideal accessory dwelling unit, long-term rental, or private space for extended family.
