847-851 Lombard St, San Francisco, CA 94133

The three-story multi-family residential building at 847-851 Lombard Street in Russian Hill, owned by Leah Ahn, was built in 1917 and contains three units. The building has undergone significant maintenance and upgrades over the years, with major electrical work completed in 2004-2007, including a complete rewiring of the flat, installation of new panels, and addition of various electrical fixtures. A fire sprinkler system was installed in the garage in 2008, followed by various maintenance works including roof access modifications in 2015.

The building has experienced several concerning issues, particularly relating to paint and safety compliance. In 2016, there were violations regarding peeling paint and potential lead hazards, though these were abated by 2018. A 2015 violation involved unpermitted construction of a roof deck and alteration of a roof hatch, which was addressed through subsequent permits.

The property has had recurring plumbing issues, with multiple sewage backup incidents reported between 2015 and 2024, most recently in October 2024. While there was one documented cooking fire incident (involving a confined container) on record with no civilian injuries, it appears to have been an isolated occurrence. The building's maintenance history shows regular attention to infrastructure, though the pattern of lead hazard citations and plumbing issues suggests ongoing concerns that have required multiple interventions over the years.
