1801 California St, San Francisco, CA 94109

1801 California Street is a 5-story, 31-unit multi-family residential building constructed in 1926 in the Lower Pacific Heights neighborhood, currently owned by SF Multifamily 1 LLC. The building has undergone significant renovations and improvements over the past several years, most notably the conversion of ground floor garages into four ADUs (Accessory Dwelling Units), with work including new windows, doors, and a fire sprinkler system installation in 2023. Between 2020-2021, substantial unit renovations were completed in multiple apartments (units 202, 502, 503, 504, 306, and 404) including bathroom and kitchen rehabilitations, as well as the installation of mini-split heat pumps in units 32-35 in 2023.

The building has also seen major safety system upgrades, including a complete fire alarm system replacement in 2022 and ongoing sprinkler system improvements. The property has experienced several maintenance and regulatory issues, particularly related to boiler permits, with violations recorded in 2018 and 2022 regarding unpermitted boiler operation, though these violations were eventually abated. A sleeping area requirements violation was issued in December 2023 that remains open according to the latest records.

There have been previous concerns about the elevator's reliability in 1996 and exposed wiring in 2016, but these issues were resolved. The building's fire safety systems have had their share of challenges, with multiple false alarms and system activations recorded, though none resulted in civilian injuries. Recent complaints in late 2024 regarding mechanical noise and garbage issues outside the building indicate ongoing maintenance and environmental challenges in the surrounding area. Two tenant buyouts were recorded, in 2016 for $12,000 (2 tenants) and in 2020 for $40,000 (1 tenant), suggesting previous unit conversions or upgrades.
