109 Masonic Avenue

109-111 Masonic Avenue presents an exceptional opportunity to own a classic San Francisco duplex in the highly desirable Lone Mountain neighborhood. Offered at $1,695,000, this well-maintained two-unit property features two spacious 2-bedroom, 1-bath residences, blending timeless architectural character with the flexibility of owner-occupancy and rental income. One residence will be delivered vacant, while the second is tenant occupied, providing immediate income. Unlike condominium ownership, this duplex offers ownership of both the building and the underlying land, with no HOA dues and the opportunity to offset monthly ownership costs through rental income. Beautiful period details, hardwood parquet floors, decorative plaster ceilings, graceful archways, abundant natural light, generous storage, and a shared backyard reflect the enduring charm of classic San Francisco architecture. Ideally located in Lone Mountain, the property is just blocks away from the University of San Francisco, Golden Gate Park, Laurel Village, the Geary Boulevard corridor, Trader Joe's, Target, neighborhood cafs, restaurants, shopping, and convenient public transportation. Whether you are seeking a primary residence with supplemental income, a multigenerational living opportunity, or a long-term investment, 109-111 Masonic Avenue offers a rare combination of character, location, and value in one of San Francisco's most sought-after neighborhoods.
