2329 Balboa St, San Francisco, CA 94121

The two-unit residential building at 2329 Balboa Street in San Francisco's Central Richmond neighborhood is a two-story flats and duplex structure constructed in 1916, currently owned by Angela Xiao Na Zhao. The building has undergone several significant maintenance and infrastructure updates over the years, with the most recent being a $15,000 reroofing project permitted in May 2021.

Historical building improvements include horizontal work completed in 1993 with a $30,000 budget, and a revision permit from 1994, though the specific nature of these earlier projects is not detailed in the records. The property has experienced multiple infrastructure challenges, most notably a series of sewage backup incidents in July 2016, with three separate service calls to the PUC Sewer Operations to address issues involving both 4-inch sewer vents and a catch basin. These sewer problems were ultimately resolved through field work and flushing operations.

The electrical system also required attention in January 2010, when burnt wiring from a capacitor needed repair at the intersection of Balboa and 100W lamp. The building's exterior environment has faced some quality-of-life issues, as evidenced by several 311 calls regarding street cleaning and loose garbage between 2016 and 2020, along with a graffiti incident in March 2017 that was addressed by SES Graffiti Crew. While these exterior issues have generally been resolved, they indicate occasional challenges with building surroundings, particularly during the 2016-2020 period.
