475-477 Crestmont Dr, San Francisco, CA 94131

The two-unit residential building located at 475-477 Crestmont Drive in Forest Knolls is a two-story flats and duplex structure built in 1968, currently owned by William J. and Jean Sieper.

The building's maintenance record shows two significant structural interventions: a deck repair due to dry rot in 1992 and a complete reroofing project in 1989, both of which were properly completed according to permit records. The property has experienced multiple reports of abandoned vehicles in the vicinity between 2013 and 2019, with six separate incidents recorded through the Department of Public Transportation Abandoned Vehicles Work Queue.

These vehicles, including various makes such as Lexus, Ford, BMW, and Honda, were typically resolved quickly as they were gone upon inspection, with resolution dates ranging from one to several days after the initial reports. More recently, there was one report of an encampment in September 2023, though this was marked as "Closed Unable to Locate" by the HSOC Queue agency. While the building's permit history shows attention to structural maintenance, the area around the property has experienced recurring issues with abandoned vehicles, though these appear to be promptly addressed by authorities when reported.
