Well-maintained three-unit property featuring expansive flats totaling approximately 5,941 SqFt, currently operated under a master lease structure providing stable income with minimal owner management responsibilities. The property is leased in its entirety to a master tenant who rents individual rooms on a per-room basis while paying the owner a fixed monthly rent. The master tenant is responsible for all utilities, including water, sewer, Recology, gas, electricity, and internet, creating a streamlined and largely passive ownership opportunity with predictable income and limited day-to-day management requirements. The building has been extensively improved and professionally maintained over time. Major capital upgrades include foundation replacement and a full seismic upgrade, interior remodeling, and installation of updated fire-life-safety systems including a fire alarm system and sprinklers. Recent 604 compliance work has been completed, and a new roof was installed in 2025, providing longterm ownership confidence. Ideally located in the heart of Haight Ashbury, 1651-1655 Oak Street benefits from immediate access to Golden Gate Park, the vibrant Haight Street commercial corridor, and the Divisadero dining and retail district. The property offers excellent connectivity via nearby MUNI transit lines and convenient access to downtown, UCSF, and major employment hubs, supporting consistently strong rental demand in one of San Francisco's most iconic and supply-constrained neighborhoods.
