426 28th Ave, San Francisco, CA 94121

This two-unit multi-family residential building, located in San Francisco's Central Richmond neighborhood, is owned by Patrick and Delia Keenan and has been standing since 1908. The property underwent significant renovations in the early 2000s, including a major horizontal and vertical addition completed in 2005 that aimed to create a legal apartment with garage space.

This construction phase was accompanied by substantial electrical upgrades, including the installation of a new 200-amp service and complete rewiring of the house in early 2003. The building's roof was replaced in 1995, and in 2010, a second address (426A) was officially assigned to the lower unit. More recently, the property has had minimal documented issues, with the most significant concerns being parking-related incidents in 2023 (driveway blocking) and 2020 (sidewalk parking), both of which were resolved through enforcement action.

Several 311 service requests between 2016-2020 related to street cleaning and maintenance issues outside the property, as well as reports of abandoned vehicles, though these were not directly related to the building's condition or operation. The most recent service request was submitted in February 2024 but was cancelled before resolution. The building's extensive permit history suggests proper maintenance and upgrading of core systems, with no major structural or safety issues reported in recent years.
