2050-2052 20th St, San Francisco, CA 94107

The two-unit residential building at 2050-2052 20th Street in Potrero Hill, owned by the Staprans Family Trust, is a two-story flats and duplex structure built in 1970. The property's maintenance record shows two significant window upgrade projects in December 2014, when eight windows were replaced with Andersen wood-clad windows to meet egress and energy efficiency standards, costing over $15,000.

Earlier records indicate that the building underwent reroofing work in January 1996. The property has experienced several infrastructure issues over recent years, with the most notable being a sewage backup incident in January 2021 that required resolution by the Public Utilities Commission Sewer Operations.

Other external infrastructure matters include a curb or ramp defect reported in September 2021, which was resolved but involved multiple issues including an abandoned driveway and tree-related concerns. There have also been occasional neighborhood disturbances such as a parking violation on the sidewalk in August 2018 involving a Honda CR-V, though the responding officer was unable to locate the vehicle. A planning record from December 2014 indicates concerns about illegal front yard parking and requests for enforcement of parking regulations regarding paved parking in the front setback area, though it's unclear from the records whether this issue has been resolved or persists.
