1647-1649 9th Ave, San Francisco, CA 94122

The two-unit residential building at 1647-1649 9th Avenue in San Francisco's Inner Sunset neighborhood, owned by Kathleen Lum 2001 Lvg Tr, was constructed in 1962 and has undergone several significant renovations and improvements over the past decades. Most notably, between 2011-2012, the property underwent extensive bathroom remodeling in both units, including plumbing upgrades, installation of new fixtures, and electrical work such as adding recessed lighting.

The building has seen consistent maintenance and upgrades, including a complete window replacement (16 vinyl windows) in 2009, reroofing in 2006, and an underground electrical service conversion in 2003. A building complaint was filed in March 2022 regarding unpermitted work, though this case was quickly abated within one day. Recent maintenance history shows the property has experienced some service-related incidents, including a flooding issue in April 2021 that was resolved by PUC Sewer Operations.

There were also several public works requests in 2021-2022 related to street and sidewalk cleaning, though these were generally not directly related to the building's condition. The most recent building improvement was completed in 2012 with comprehensive bathroom renovations across both units. The property appears well-maintained overall, with regular updates to essential systems, though the presence of unpermitted work in early 2022 merits noting as a recent exception, despite its prompt abatement.
