1405-1407 41st Ave, San Francisco, CA 94122

This two-unit multi-family residential building, located at 1405-1407 41st Avenue in the Outer Sunset neighborhood, is a 2-story flats and duplex structure built in 1945 and currently owned by Loranta and Norman Louie.

The building's maintenance history reveals several significant repairs over the past three decades, including a garage door header replacement in 2010, roof replacement in 1991, and garage door jamb repairs in 1994. Of particular concern are recurring sewer issues, with three documented sewage backup incidents between 2019 and 2021, including one notable incident in February 2019 involving a grease blockage that required intervention at the trap.

The property has also experienced multiple parking enforcement issues in recent years, with five documented cases of driveway blocking between 2018 and 2021, suggesting ongoing challenges with parking management in the area. While the building has undergone necessary maintenance and repairs over the years, the pattern of sewer system issues, particularly the most recent occurrences in 2020 and 2021, may indicate a continuing infrastructure challenge that requires monitoring.
