1235 11th Ave, San Francisco, CA 94122

The two-unit residential building at 1235 11th Avenue in San Francisco's Inner Sunset neighborhood is a two-story flats and duplex structure built in 1907, currently owned by Loreta Colanbianchi. The building's maintenance history reveals attention to safety infrastructure, particularly regarding the rear exterior stairs, with documented repair work in 1996 (which unfortunately expired) and again in 1997, suggesting ongoing concerns in this area, though no recent stair-related permits have been filed.

The building received a complete reroofing in 1990, and there are two additional completed permits from 1981, though their details are not specified in the records. More recent incidents primarily relate to parking enforcement issues, with six documented cases of driveway blocking between 2018 and 2019, three of which resulted in citations being issued.

The most recent service calls include a garbage and debris complaint in November 2024 that was resolved, and a double parking issue in December 2024 that was logged for data collection purposes. Of particular note are two sewer-related incidents in October 2011, involving a sewage backup and a subsequent customer callback regarding the property's sewer trap, which may indicate historical plumbing concerns that warrant monitoring. While the building has undergone necessary repairs and maintenance as documented through permits and inspections, the pattern of parking enforcement calls and the earlier sewer issues stand out as areas of note in the building's service history.
