531 41st Ave, San Francisco, CA 94121

The two-unit residential building at 531 41st Avenue in San Francisco's Outer Richmond district is a 2-story flats and duplex structure built in 1903, currently owned by Chananudech Benjavan & Luck. The property's maintenance history reveals several significant events, with the most recent being a complaint filed in September 2024 regarding unpermitted plumbing work and concrete modifications.

This follows a pattern of construction-related issues, including a 2015 violation concerning hazardous exterior stairs and siding replacement that went through multiple notice stages before being abated in March 2018. The building underwent vertical and horizontal additions in 1988, reflecting substantial past modifications to the structure.

Recent concerns primarily relate to parking and noise issues, with three reports of excessive noise and multiple complaints about driveway blocking between 2021 and 2024, though most parking enforcement matters were resolved through officer intervention. There were also two relevant maintenance issues reported in 2021-2022: an abandoned vehicle incident and exposed cable concerns that were determined to be cable company equipment rather than streetlight wiring. While the building has experienced some maintenance and compliance challenges over the years, particularly regarding construction work, the property has undergone several significant improvements, including the 2015 siding and stair repairs and the 1988 expansion project.
