154 10th St, San Francisco, CA 94103

The 12-unit, 3-story apartment building at 154 10th Street in the South of Market neighborhood, owned by the Woo Family Trust 1990, has undergone several significant maintenance and safety-related improvements since its construction in 1912. Most notably, the building completed a mandatory soft-story retrofit in 2018 at a cost of $49,000 to improve seismic safety.

Recent years have seen persistent fire safety concerns, with three violations recorded in 2024 alone regarding alarm systems and standpipe maintenance. The building has experienced recurring maintenance and safety issues, including multiple instances of water temperature problems in 2021 (with temperatures exceeding 150°F at kitchen sinks), window safety concerns, and recent heating system problems in late 2024, including a 12-hour hot water outage. Historical improvements include various repairs and upgrades such as roofing work in 1988, chimney lining in 1990, and various permits for addressing dry rot and bathroom modifications between 2005-2011.

The property has faced multiple building code enforcement actions over the years, including several incidents of unauthorized basement occupancy and illegal storage violations between 2001 and 2021, though most of these issues were resolved through corrective actions. Recent 311 calls from early 2025 indicate ongoing challenges with external building maintenance and street conditions, including reports of debris, graffiti, and unauthorized encampments in the vicinity of the property. While the building has generally complied with most safety requirements, the pattern of recent violations and complaints suggests ongoing maintenance challenges that require attention.
