1200 Clay St, San Francisco, CA 94108

The 18-unit, 3-story apartment building at 1200 Clay Street, owned by the Hung On Tong Society, was constructed in 1923 in the Nob Hill neighborhood. The property has undergone numerous renovations and upgrades over the years, with the most recent significant work being a domestic hot water boiler replacement in June 2023, which followed several routine boiler permit renewal issues between 2020-2023. The building has experienced recurring fire safety concerns, with fire-related violations and complaints primarily between 2018-2024 regarding fire escape ladders, extinguishers, alarm systems, and combustible materials, though most of these issues were properly corrected upon inspection.

Recent building complaints from March 2024 noted multiple fire safety concerns, including fire escape ladder functionality and combustible storage, which were marked as Not Active after inspection. Historical improvements to the property include a 2018 emergency fire alarm panel replacement, 2016 window upgrades, and substantial renovations to unit #12 in 2014 (including kitchen and bathroom remodeling and structural modifications). The building has a documented history of AT&T telecommunications equipment modifications between 2009-2016, indicating partnership with telecommunications infrastructure use.

Several routine inspections over the years have revealed various maintenance issues, including a 2024 complaint about general maintenance that was addressed promptly. Recent 311 calls (December 2024) show multiple parking enforcement issues around the property, though these are separate from building conditions. While the building occasionally experiences system malfunctions (as evidenced by several service calls from the fire department), there have been no significant fire incidents or civilian injuries recorded in the building's history, suggesting that safety systems generally function as intended when properly maintained.
