408-410 12th Ave, San Francisco, CA 94118

The property at 408-410 12th Avenue in San Francisco's Inner Richmond neighborhood is a two-unit multi-family residential building constructed in 1979, currently owned by the Elizabeth T Ing Survivors Trust.

The two-story flats and duplex structure has a documented history of maintenance issues, most notably concerning the back balconies and decks, which were found to have severe dry rot on the 2nd and 3rd floors in 2019, prompting a violation notice that was eventually resolved in January 2020 following $22,000 worth of repair work completed in late 2019. The building has undergone some significant maintenance work over the years, including a reroofing project in 2015 costing $10,500 and a previous roofing project in 1991, though the latter expired without completion.

Historical records show earlier issues including an illegal kitchen in ground floor habitable space in 1999 and a failed attempt in 1994 to legalize certain living spaces and remove appliances. More recently, there have been two environmental service calls to the vicinity - one in 2024 regarding general cleaning and another in 2021 concerning hazardous materials (glass) - though these were related to street conditions rather than building-specific issues.
