335 Bassett Street Set in the coveted Oakhill-Brewster Historic District, this West Petaluma property spans two lots a rare footprint just steps from downtown. A welcoming front porch opens to a formal entry, living room, and adjoining dining room, while the bright kitchen is full of period character and connects to an enclosed back porch overlooking the deep, mature yard. The main home offers two generous bedrooms and a full bath, and a separate, move-in-ready ADU adds a private one-bed, one-bath with its own living area and full kitchen, complete with a new fridge, oven/range, and professionally resurfaced floors ideal for guests, rental income, or multigenerational living. Custom cabinets, closets, and built-ins throughout keep storage effortless, and a 2-car garage rounds out the space. What truly sets this property apart is its self-sufficiency: a fully owned solar system with multiple battery banks and a private well delivering abundant water for the home and backed by a water softening system and full irrigation to keep the grounds lush year-round.
