578-580 20th Ave, San Francisco, CA 94121
The Wong Family Trust owns this well-maintained two-unit multi-family residential building located at 578-580 20th Avenue in the Central Richmond neighborhood. Built in 1922, this two-story flats and duplex structure has undergone several significant improvements over the past decade, with the most substantial renovation occurring in 2018 when comprehensive updates were made to both bathrooms and kitchens, including the replacement of all fixtures and appliances at a cost of $35,000. This renovation was accompanied by electrical upgrades, including the installation of new lighting, switches, receptacles, and modern appliances such as a dishwasher, garbage disposal, microwave, and range.
The building's infrastructure improvements are noteworthy, with a 200-amp electrical service upgrade completed in 2011 and the installation of a new water meter and main line that same year. The property has experienced minimal building-related issues in recent years, though there was one significant incident involving a sewage backup in February 2020 that was promptly resolved by PUC Sewer Operations. The building's location has experienced typical urban challenges, including several parking-related complaints between 2015 and 2022, though these issues were primarily street-related and not directly concerning the property itself.
An illegal construction complaint was filed in December 2016, which was resolved through proper channels. The building's maintenance record, particularly regarding plumbing and electrical systems, suggests regular upkeep and modernization, with no recent permits or complaints suggesting ongoing maintenance issues or safety concerns. The property's documented history shows regular maintenance and upgrading of essential systems, with significant investments in modernization occurring approximately every seven years (2011 and 2018) for both plumbing and electrical infrastructure, alongside cosmetic and functional improvements to individual units. The building's location has experienced typical urban challenges, including several parking-related complaints between 2015 and 2022, though these issues were primarily street-related and not directly concerning the property itself.
