1850 Jefferson St, San Francisco, CA 94123

The Borella Family Trust's multi-family residential building at 1850 Jefferson Street in the Marina neighborhood is a two-unit, two-story structure built in 1937. The property has undergone several significant improvements over the past few years, with the most recent being the installation of two combi boilers in September 2023, and prior to that, a foundation repair in January 2024 addressing issues caused by nearby excavation work. The building has experienced some maintenance challenges, with complaints filed in 2019 regarding old carpeting and mold in closets, and in 2007 concerning dry rot in the back porch, though these issues were promptly resolved.

More recent structural concerns emerged in December 2023 regarding foundation undermining, which was addressed by January 2024. The property has seen regular maintenance work, including reroofing in 2018 and earlier structural repairs in 1989 involving step replacement and stucco work. Infrastructure improvements include a new pressure reducing valve system installed in 2017, though this permit is currently marked as expired.

While there have been two fire-related incidents on record - an unintentional alarm transmission and a gas leak, both with no civilian injuries reported - these incidents appear to have been handled without significant impact on resident safety. The building has experienced ongoing issues with parking violations in the vicinity, with multiple citations issued for driveway blocking and sidewalk parking between 2023 and 2024, though these are external to the building itself. Regular street cleaning services have been requested and provided for the area, with the most recent service call in November 2023.
