550 41st Ave, San Francisco, CA 94121

The two-unit residential building at 550 41st Avenue in San Francisco's Outer Richmond district, owned by the Young Family Trust, is a two-story flats and duplex structure built in 1948. The property has undergone several significant improvements over the years, with the most substantial recent work occurring in 2014, when both dry rot repairs and window upgrades were completed.

In September 2014, dry rot repair work was performed on both the front and back of the building, including stucco replacement, at a cost of $35,000. This was followed by the installation of four fiberglass wood-clad windows at the front of the building in October 2014. Earlier improvements include window replacements in 1999, when all wood single-glazed windows were upgraded to vinyl, and a sidewalk repair permit issued in 2002.

The property has experienced multiple parking-related incidents in recent years, with driveway blocking violations reported in 2024 (two incidents), 2018 (three incidents), and one construction materials blocking case in 2017. Other notable events include a pavement defect report in July 2019, an environmental health service request in July 2018, and an abandoned vehicle complaint in December 2010. While the recent parking enforcement issues (two in 2024) and the 2014 structural maintenance work are the most significant recent events, the building's maintenance history shows attention to necessary repairs and improvements over the years, particularly regarding window upgrades and moisture-related issues.
