Overview

Outstanding value and location! Freshly updated inside and out, this charming 1926 bungalow offers classic appeal in the sought-after Sign Hill neighborhood. All new paint, carpet, and fencing enhance the bright, welcoming feel inside and out. City and hill views unfold from the living room plus there is a spacious kitchen and dining area. There are 3 bedrooms, 1 bath, and a large laundry room with outside access and stairs to the lower-level tandem garage. Two large storage/workshop areas and a bonus bath with shower (without the benefits of permits) offer potential for added living space on this level (buyer to confirm with City). The approximately 4,000-sf lot includes a generous, fenced side yard with space for gardening, play, or possible ADU (buyer to verify). Great location just blocks to downtown shops, cafes, and Spruce Elementary, less than a half mile to the Sign Hill Park trailhead, plus minutes to biotech centers, BART, and freeway access to San Francisco or Silicon Valley.
