1645-1647 Bay Shore Blvd, San Francisco, CA 94124

The property at 1645-1647 Bay Shore Blvd is a two-story, two-unit multi-family residential building constructed in 1925, currently owned by Gloria M. St. Thomas.

The building's history reveals persistent issues with unauthorized unit conversions, with the most significant violation occurring in 2008 when illegal modifications were discovered in the ground level, including an unauthorized separate unit with its own entrance, three bedrooms, bathroom, and kitchenette with gas stove. This violation prompted several enforcement actions and required permits to convert the unauthorized space back to storage, including comprehensive removal of kitchen and bathroom facilities in 2006 and 2008, with costs totaling $15,000. These violations included serious safety concerns such as lack of smoke detectors, inadequate emergency egress, unapproved electrical wiring and plumbing, and questions about fire-resistant construction materials. The building has experienced multiple maintenance and safety issues over the years, with a significant complaint recorded in 1995 regarding severe water leaks, heating problems, and plumbing issues, which currently remains active.

Additional historical complaints from 2000-2001 documented various maintenance issues including inadequate bathroom ventilation, security concerns with windows and doors, pest problems, and questions about unit legality. More recently, the property has been the subject of numerous parking-related complaints in late 2024 and early 2025, primarily involving vehicles parking on the sidewalk, with several citations issued, though these are unrelated to the building's habitability conditions. The most recent permit activity includes a completed gas houseline extension in 2014. The property's documented history shows a pattern of unit conversion violations, safety concerns, and maintenance issues that have required multiple governmental interventions to address.
