636-642 Ivy St, San Francisco, CA 94102

The property at 636-642 Ivy Street in Hayes Valley is a two-story, four-unit multi-family residential building constructed in 1900 and currently owned by the Christopher-Smith 2017 Trust. The building has undergone several significant maintenance and repair projects over the years, including recent re-roofing work valued at $14,000 initiated in July 2024. However, there are currently unresolved serious issues, including active violations filed in July 2023 related to general dilapidation, interior surface problems, and potential lead paint hazards, with specific concerns about damaged ceilings, walls, and lingering water damage/mold issues from an upstairs unit.

Historical data shows a pattern of maintenance challenges, including a plumbing issue in 2010 involving a broken waste pipe, and previous significant repairs in 2001 addressing wall framing and foundation problems. The building's repair history includes various improvements such as a deck repair in 1993 and kitchen/bathroom remodeling in the same year. There have been multiple routine safety inspections conducted over the years (most recently in 2018), and the building has experienced some concerning events, such as a 2010 incident involving sewage leakage affecting a neighboring property.

While some maintenance issues have been addressed promptly, as evidenced by the recent re-roofing project, the presence of active violations from July 2023 suggests ongoing maintenance challenges. Recent 311 calls from early 2024 primarily relate to external issues such as garbage collection concerns and illegal parking, which, while not directly related to building conditions, indicate some neighborhood maintenance challenges. A carbon monoxide detector activation incident was reported but resolved with no CO detected or civilian injuries.
