First time on the market in generations, 133-135 11th Avenue offers a rare opportunity to step into a vacant two-unit property tucked between Lake Street and California Street in one of San Francisco's most beloved residential neighborhoods. Filled with natural light, warmth, and possibility, the property has been thoughtfully prepared to create a clear and welcoming experience for buyers. Extensive cleaning, inspections, and targeted improvements have already been completed, allowing the next owner to walk through the home with a strong sense of openness, transparency, and opportunity. The interiors offer generous scale, classic character, and an inviting atmosphere that feels immediately livable while still leaving room for personalization and future vision. Refinished hardwood floors, fresh presentation work, and updated interior and exterior touches help the property feel bright, approachable, and full of potential. The rear yard provides a flexible outdoor space ready to be enjoyed today and thoughtfully evolved over time. Neighboring properties demonstrate a clear pattern of expanded rear-yard use and accessory structures (buyer to investigate), offering inspiration for what may be possible in the future. What makes this property especially compelling is the balance it strikes: honest condition, clear disclosures, and meaningful upside-all in a location where long-term ownership truly matters. Just moments from the Presidio, Mountain Lake Park, Clement Street, California Street shops and dining, and neighborhood conveniences. Commuting is a breeze to the Financial District, Silicon Valley, The East Bay and beyond. 133-135 11th Avenue presents an exciting opportunity for owner-users, investors, multigenerational living, or anyone looking to create lasting value in San Francisco. A home with heart, light, and room to grow.
