634-640 Lombard St, San Francisco, CA 94133

The 8-unit, 3-story multi-family residential building at 634-640 Lombard Street in North Beach, owned by the Choi Kam Yau Trust, was constructed in 1907 and has undergone several significant safety, maintenance, and infrastructure improvements over the past two decades. Most notably, in 2023, the building received substantial fire safety upgrades including a new fire alarm control panel, wireless communicator, LED annunciator, smoke detectors, manual pull stations, and low-frequency sounders, with a total investment of approximately $41,293. Prior to this, the building completed a mandatory soft-story retrofit in 2016 (Tier 4) to improve seismic resilience, and in 2019, underwent sewer line improvements to correct grade issues.

Other important maintenance work included the rebuilding of a rear stairway and walkway repairs in 2004 ($7,000). The building's maintenance record shows regular attention to safety and compliance issues, with the most significant violation occurring in 2014 related to lead paint hazards on the west wall, which was promptly resolved within three weeks. Three routine housing inspections conducted between 2001 and 2006 did not result in any documented violations.

The property has experienced one documented fire-related incident involving a smoke detector activation (without fire) with no civilian injuries. Recent 311 calls from 2022 to 2024 primarily relate to external issues such as street cleaning, tree maintenance, and park services, rather than building-specific concerns. A single parking enforcement call regarding a blocking vehicle was recorded in October 2023, though the responding officer was unable to locate the vehicle.
