724 Brazil Ave, San Francisco, CA 94112

The two-unit residential building at 724 Brazil Avenue in the Excelsior neighborhood, owned by Jochen & Caroli Hagenstroem, was constructed in 1930 as a flats and duplex structure over two stories. The property has undergone several significant renovations and faced multiple safety concerns over its history. Recent improvements include a $17,000 reroofing project in 2022, the installation of a solar panel system in 2018, and an important plumbing upgrade in 2019 that replaced galvanized water lines with copper.

The building has experienced recurring maintenance issues, with three roofing projects documented between 1993 and 2022, and various electrical improvements including hazardous wiring corrections and load center replacement in 2003. The property has a concerning history of safety complaints, particularly during 2022 when multiple reports were filed regarding electrical hazards, abandoned appliances, and pest issues. Earlier incidents from 1996-2003 documented more severe problems including flooding, mold, dry rot, and electrical concerns that were apparently resolved.

Recent records from late 2024 show multiple reports of garbage and debris issues around the property, though these were generally addressed promptly by city services. Two significant building improvement projects were planned but not executed: a 2016 revision to replace exterior siding, stairs, and update systems was cancelled, and a previous 2015 permit for window, door, and garage repairs was issued. The building's infrastructure has received periodic attention, as evidenced by historical permits for stair replacement (1994) and various maintenance work, though many projects appear to be reactive rather than part of a cohesive maintenance strategy.
