6533 California St, San Francisco, CA 94121

The two-unit residential building at 6533 California Street, located in San Francisco's Central Richmond neighborhood, has a storied history dating back to its 1907 construction. The one-story flats and duplex property, currently owned by Michael David Mah, underwent significant improvements with a rear three-story horizontal addition completed in 2005 at a cost of $360,000, and more recently, a $17,000 reroofing project completed in 2015. However, the building has faced serious maintenance challenges in recent years, most notably documented in an active complaint filed in August 2019 that remains unresolved as of October 2023.

This complaint details multiple violations related to weather proofing and paint conditions, with specific concerns about lead hazards. A previous complaint from January 2018 also highlighted the property's deteriorating condition, though this was eventually closed. The property has experienced recent infrastructure issues, with two sewage backup incidents reported in November 2024.

Parking enforcement has been a frequent concern, with multiple citations issued between November 2024 and January 2025 for driveway blocking violations, suggesting ongoing challenges with street access. While the building's historical improvements demonstrate some investment in the property, the persistent maintenance issues and recent sewer problems raise significant concerns about the building's current condition and resident experience. The building's documented history shows a pattern of recurring maintenance challenges, with the most pressing current issues centering around exterior maintenance and sewer infrastructure.
