1285-1287 48th Ave, San Francisco, CA 94122

The two-unit residential building at 1285-1287 48th Avenue in San Francisco's Outer Sunset district is a two-story flats and duplex structure built in 1959, currently owned by Eric Chau and Sandy Zhao. The property underwent significant interior improvements in 2006, when a substantial renovation added a playroom, bedroom, 1.5 bathrooms, and a laundry room to the lower unit, with the electrical work for this project completed that same year.

In 2012, the building was outfitted with solar energy equipment, including six roof-mounted PV modules and an inverter system rated at 1.38 kW, representing a sustainable energy upgrade for the property. The building's recent history shows several external issues primarily related to parking and street maintenance. There have been two documented instances of sidewalk parking (2019 and most recently in January 2024), with the 2019 incident resulting in a citation.

The property has experienced some environmental health-related concerns, with a general request noted in September 2016 that was transferred to the Department of Public Health's Healthy Housing and Vector Control division. Other minor incidents include a noise complaint in June 2020 that was deemed invalid and a cleaning issue involving loose garbage in September 2020. Two reports of abandoned vehicles near the property were filed in 2016 and 2021, with the 2021 incident resolving itself when the vehicle complied with parking regulations.
