4906-4908 California St, San Francisco, CA 94118

4906-4908 California Street is a two-unit, two-story multi-family residential building located in the Lake-Presidio neighborhood. Built in 1924 and currently owned by Ari Baruth & Clara Hatcher, this flats/duplex property has undergone significant modernization and safety improvements in recent years. Most notably, there has been substantial work on fire safety systems, including the recent 2024 upgrade of the fire alarm system to comply with SFFC regulations and the installation of a fire sprinkler system for the ground floor and ADU in 2023, with additional fire safety work ongoing into 2024.

The building underwent substantial renovations in 2016, including kitchen and bathroom remodels, laundry room relocation, and window replacements. A notable project in 2019 involved the legalization of a ground floor studio unit and associated safety system installations, with subsequent bathroom and storage room work totaling approximately $62,000 combined. The property has seen regular maintenance and upgrades to its core systems, including two furnace replacements in late 2021 and a 2023 electrical service relocation with new meter installations.

Historical records show earlier improvements such as reroofing work completed in 1989. The building has experienced minimal serious issues, with only two recorded fire-related incidents - a false alarm and a hazardous condition, neither of which resulted in civilian injuries. Recent 311 calls have primarily focused on general cleaning and maintenance issues in the vicinity of the property, with most cases being promptly resolved. The property's recent permit activity and systematic upgrades suggest active management and compliance with current safety standards.
