1765 Leavenworth St, San Francisco, CA 94109

The two-unit residential building at 1765 Leavenworth Street in San Francisco's Russian Hill neighborhood, owned by the Woo Family Trust, was originally constructed in 1907 and has undergone significant recent renovations totaling over $800,000 in permit costs. The most substantial work occurred between 2017-2023, including the installation of a new foundation, addition of a third floor, new bay windows, interior renovations to both units, and a garage expansion.

The building received comprehensive safety upgrades, including the installation of an NFPA 13R sprinkler system throughout, with recent work continuing into 2023 for monitoring systems and fire alarm components. Major system upgrades were completed in 2022, including full rewiring of the units, new electrical service, plumbing updates for multiple bathrooms and kitchens, and the installation of a heat pump system.

More recently, the property has experienced some external maintenance issues, as evidenced by six parking enforcement calls regarding driveway blocking between 2023-2024, a sidewalk collapse incident in 2024 requiring utility repairs, and reports of graffiti on the mailbox in late 2024. The building's renovation history shows substantial investment in modernizing the structure and improving safety systems, though the 311 service requests suggest ongoing challenges related to street parking and sidewalk maintenance around the property. The most recent building permits indicate that all major construction and safety upgrades have been completed, with the building now equipped with modern fire safety systems and updated living spaces.
