642 Broderick St, San Francisco, CA 94117

The three-story, four-unit multi-family residential building at 642 Broderick St, constructed in 1900 and owned by the Michael J Mazgai Living Trust, has undergone several significant infrastructure improvements over the past decade. Most notably, in 2019, both the underground drainage system and first-floor water supply lines were completely overhauled, representing a substantial modernization of the building's plumbing infrastructure.

The property received a new roof in 2014, costing nearly $16,000, and earlier structural improvements included the installation of an automatic garage door system in 1987. Recent maintenance work has also focused on the exterior, with street space and sidewalk repairs occurring in 2019. The building has experienced recurring issues with parking violations in the vicinity, particularly regarding driveway blockages, with multiple enforcement actions recorded between 2021 and 2024.

While most of these incidents resulted in citations or administrative resolutions, there were several instances where responding officers were unable to locate the offending vehicles. Additionally, there have been two documented instances of parking violations on the sidewalk in late 2019 and early 2020, though enforcement officers were unable to locate the vehicles in these cases. The property has also required some tree maintenance, with reports of overgrown trees in 2018 and sidewalk-damaging roots in 2019, though these issues were addressed through the city's regular maintenance processes.
