228-230 25th Ave, San Francisco, CA 94121

The two-unit residential building at 228-230 25th Avenue, located in the Lake-Presidio neighborhood, is a two-story flats and duplex structure built in 1911 and currently owned by Joo Kwan & Sau Ying Yee Rev. The property has undergone several significant maintenance and improvement projects over the years, with the most recent being a completed roofing project in November 2024, valued at $13,000.

Historical records show major internal improvements in the 1980s, including repair work on two kitchens and bathrooms (1987), internal alterations (1986), and a comprehensive remodeling project involving electrical systems, kitchen, and bathroom improvements (1985). In 1992, repair and replacement work was completed on 13 steps of the rear stairs. Of particular concern is a recurring pattern of sewer-related issues documented through 311 calls, with the most recent incident occurring in January 2024 involving a 4-inch sewer vent issue.

The property experienced multiple flooding incidents between June 2018 and January 2019, with documented flooding on the property in 2018 occurring at least eight times during that year. While all these incidents were officially resolved through various work orders and interventions by PUC Sewer Operations, the persistent nature of these sewer issues suggests an ongoing infrastructure challenge. The only non-sewer-related incident in recent years was a graffiti complaint on a pole in January 2019, which was promptly addressed by the DPW Operations team.
