508-510 45th Ave, San Francisco, CA 94121

The property at 508-510 45th Avenue in San Francisco's Outer Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1922, currently owned by Tom Thomas Wong Wah Sai. The building has undergone several significant maintenance and improvement projects, most notably in August 2010 when extensive renovations were completed at unit #508, including repairs to dry-rot siding on the south and east sides, kitchen and bathroom renovations, window replacements, and deck repairs, with a total cost of $30,000.

Other permits from the same period show plumbing and electrical work, including kitchen sink replacement and additional receptacles in the kitchen area. The building's maintenance history shows attention to structural upkeep, with earlier permits from 2002 indicating vinyl siding installation and a vertical addition completed in 1990.

Recent incidents of note include a sewage-related issue in December 2023, for which two PUC service calls were made, and a plumbing inspection request in January 2024. The property has experienced two fire incidents on record: one carbon monoxide incident and one malfunctioning alarm system, though fortunately, neither resulted in civilian injuries. The building's exterior infrastructure has been maintained, with sidewalk repairs permitted in 2010, though there have been some recent neighborhood concerns such as tree-related property damage (February 2024) and various street maintenance issues.
