606-608 4th Ave, San Francisco, CA 94118

The property at 606-608 4th Avenue in the Inner Richmond is a two-unit, two-story multi-family residential building constructed in 1907, currently owned by the Lawrence D Chan Revocable Trust. The building's history shows several significant maintenance and compliance issues, particularly regarding water management systems. In early 2008, multiple complaints were filed about water drainage problems from the lightwell, which were subsequently addressed through permits for drain installation, roof drainage improvements, and electrical work.

Earlier concerns about water issues were documented in 2000 when basement flooding was reported at a neighboring property. The building underwent various structural and maintenance work throughout the 1980s and 1990s, including foundation repairs (1997), removal of an illegal unit (1997), and multiple improvements like stucco repair and reroofing, though one roofing permit from 1994 is listed as expired. Recent records from 2021-2024 show ongoing maintenance issues outside the building, with multiple reports of tree root damage to the sidewalk and several instances of driveway blocking requiring parking enforcement.

There have also been isolated incidents involving graffiti (2023) and other street maintenance concerns. While the building appears to have addressed its major historical water management issues, as evidenced by the completed permits from 2008, the property has experienced periodic challenges with adjacent tree roots affecting the sidewalk, as indicated by open maintenance requests from 2021-2022. The building's systems and structures have undergone various improvements over the years, though some historical violations and compliance matters, such as the illegal unit removal in 1997 and the cancelled stove removal compliance in 1990, suggest past issues with unauthorized modifications.
