1187-1189 Geneva Ave, San Francisco, CA 94112

The two-unit multi-family residential building at 1187-1189 Geneva Avenue in the Excelsior neighborhood, owned by Daniel D. Wong and Wai Soo Ho, has experienced significant plumbing infrastructure challenges in recent months, with four documented sewage backup incidents from the side sewer vent between November 2023 and January 2025. The property, consisting of a two-story flat and store structure built in 1922, has a mixed-use designation and previously housed a beauty salon that underwent interior remodeling in 2001, along with a 2002 installation of a 4' x 24' awning.

The building's maintenance history shows some attention to basic repairs, including work on bathrooms and kitchens in 1987, though these permits have since expired. The most concerning recent developments include the series of sewage-related incidents, which appear to be cyclical in nature, with multiple occurrences in 2024-2025. The property has also faced ongoing issues with garbage and debris, as evidenced by six separate reports between July 2024 and January 2025, suggesting possible challenges with waste management or maintenance routines.

Additional minor incidents include two parking enforcement calls in 2024 related to illegal parking, though officers were unable to locate the violating vehicles in both instances. Notably, there was a commercial/business vacant structure complaint filed in April 2023, though this complaint is currently listed as not active. The building's permit and complaint history indicates periods of maintenance work and improvements, though many of these records date back several years, with the most recent significant building permit being from 2001. The pattern of sewage-related complaints, in particular, constitutes the most pressing recent issue regarding the building's infrastructure and resident amenities.
