558-564 Castro St, San Francisco, CA 94114

The 558-564 Castro Street property is a 3-story, 10-unit multi-family residential building with commercial space, constructed in 1904 and currently owned by Arthur C.S. and Glendy Hsu. The building has undergone several significant safety-related improvements in recent years, including a completed fire alarm system upgrade in late 2024 (cost: $30,888) to comply with current fire code requirements, and a mandatory soft-story seismic retrofit completed in 2018 (cost: $63,400) that brought the building into compliance with San Francisco's seismic safety requirements.

The property has experienced recurring fire safety issues, with violations issued in October 2024 for alarm system maintenance and fire extinguisher requirements, along with several active building code violations from May 2023 regarding fire safety equipment including extinguishers, escape routes, and emergency shutoff procedures. The building has a documented history of various maintenance and improvement work, including reroofing in 2017, structural repairs in 2012, and bathroom renovations. Multiple fire safety complaints have been filed over the years, with the most recent in September 2024 resulting in violations for alarm systems and fire extinguishers.

Historical complaints from 2001 noted issues with stairs and egress obstruction that were subsequently abated. The property had some commercial use modifications in the past, including unauthorized assembly-type restaurant operation in 2008 and unpermitted remodeling in 2007, though these issues were eventually resolved. Recent 311 calls from late 2024/early 2025 primarily relate to street maintenance issues outside the building, rather than internal building conditions.
