443-445 Filbert St, San Francisco, CA 94133

The two-unit residential building at 443-445 Filbert Street is a 2-story flats and duplex structure located in Telegraph Hill, owned by Cynthia Kathleen Revel and constructed in 1907. The property underwent significant structural improvements in 2010, including foundation and retaining wall reinforcement, removal of columns and beams in the garage, alterations to interior walls and kitchen cabinets, installation of a catch basin in the garage, and comprehensive electrical system upgrades including new lighting, outlets, and appliance installations.

These improvements totaled approximately $67,000 and were completed successfully. In 2018, the building received a new roof through a $9,900 project. The property has required three street space permits over the years (2010, 2013) and had rear stairs replaced in-kind in 2010.

Recent activity around the property includes two 311 calls in 2023 related to street cleaning issues, with the most recent being an open case regarding waste on December 23, 2023, and an earlier case from February 2, 2023, which was resolved with no significant findings. While these calls indicate some maintenance issues in the immediate vicinity, they relate to street conditions rather than building-specific problems. The most substantial work on the property appears to have been completed more than five years ago, with no major building permits or significant renovations recorded since the 2018 reroofing project.
