450-452 Plymouth Ave, San Francisco, CA 94112

The two-family residential building at 450-452 Plymouth Ave, owned by San Wai Oo & Khin Sandi Shi, was constructed in 1961 and has undergone several significant modifications and faced various issues over the years. Most notably, in 2018 the property underwent substantial work to add a new 3-bedroom, 2-bath unit on the first floor to comply with local ordinance 162-16, following previous bathroom conversion work in 2017 on the second floor that aimed to increase bathroom facilities. The building experienced a serious incident in 2016 when a section of the stucco facade measuring approximately 3 by 15 feet fell from the front of the building, leading to emergency response and subsequent repairs completed in 2017.

Earlier structural concerns were addressed in 2005 with termite repairs valued at $20,000. The electrical system was significantly upgraded in 2005 and 2006, including the installation of new overhead service, circuit installations, and various electrical fixtures. The property has a documented history of various maintenance and safety issues. In September 2000, there was a concerning incident involving utilities being turned off in the lower flat, resulting in dangerous candle use.

More recent complaints from 2020 indicated issues with trash management at the property. Since December 2024, there has been a notable pattern of reports regarding garbage and debris, with multiple calls made to city services for cleanups, including furniture, mattresses, and other loose debris on the property. Two instances of driveway blocking were reported and addressed in December 2024, with citations issued. The building's recent history shows ongoing challenges with proper waste management and some concerns regarding property maintenance, though many of these issues appear to be primarily related to exterior and communal areas rather than the building's structural integrity or internal systems.
