2365 Mariposa St, San Francisco, CA 94110

The two-unit, three-story multi-family residential building at 2365 Mariposa Street in Potrero Hill, owned by Ted K & Sandra Surber, was constructed in 1991 following the demolition of a gas station on the site in 1987. The building has undergone several significant improvements over its lifetime, most notably a $13,100 reroofing project completed in 2022.

Initial construction permits from 1988 ($320,000) and 1990 ($1) were followed by a 1991 permit for a fire sprinkler system installation, though this particular permit expired. In 1992, two additional permits were successfully completed to address earlier expired permits, indicating diligence in obtaining proper approvals during the building's early years. The building has experienced relatively few major issues over its history, with only one notable building complaint reported in June 2017 regarding construction noise affecting a nearby unit, which was subsequently handled through the Building Inspection Division.

The property has generated several 311 calls in recent years, though these primarily relate to external issues such as street cleaning, parking violations, and municipal services rather than building-specific problems. These calls include reports of loose garbage (2023), driveway blocking (2019), human or animal waste (2019), and various maintenance issues like graffiti (2018) and a missing sewer vent cover (2018). The most recent building-related work, the reroofing project in 2022, suggests ongoing maintenance of the property, though the expiration of the original fire sprinkler permit from 1991 and the successful completion of subsequent permits in 1992 might indicate the building was constructed with some safety systems installed and then updated as needed.
