441 Green St, San Francisco, CA 94133

441 Green Street is a two-unit, two-story multi-family residential building located in the Telegraph Hill neighborhood, constructed in 1906 and currently owned by the Der Yen & May J Revocable Trust. The property has undergone several significant improvements in recent years, most notably a comprehensive roofing project initiated in December 2024 with an estimated cost of $16,800, involving the installation of advanced roofing membranes and replacement of flashing and vents.

Earlier maintenance work includes the completion of rear yard stairs rebuilding in 2019 at a cost of $8,000. The building's electrical system is currently undergoing updates, with an issued permit in January 2025 for the removal of three Federal Pacific Electric (FPE) panels and their replacement, following an insurance request.

A planning record indicates a previous project to replace deck and stairs in-kind, while the property experienced a notable tenant buyout in September 2020, when two tenants received a $75,000 buyout, representing the building's only recorded tenant displacement event in recent history. The property's maintenance history suggests active management, with significant investments in both structural and safety improvements.
