1900 Jefferson St, San Francisco, CA 94123

1900 Jefferson Street is a three-story, 15-unit multi-family residential building constructed in 1930 and currently owned by North Point Investments LLC. The property has undergone extensive renovations since 2020, including the controversial addition of five ADUs in the garage area, which generated multiple tenant complaints regarding construction noise and work beyond permitted scope. Between 2019-2022, significant upgrades were made to individual units (202, 203, 301, etc.), including complete rewiring, plumbing updates, and reconfigurations of interior spaces to convert units from one-bedroom to larger configurations.

The building has a history of permit compliance issues, particularly during 2020 when several complaints were filed about unpermitted work and construction during health orders. Notably, there was a violation for operating an unpermitted boiler in July 2019, though this was resolved within a month. Recent improvements include roof work completed in 2020 and various unit upgrades involving electrical, plumbing, and interior remodeling.

The building has experienced multiple fire alarm activations, though all were determined to be false alarms or system malfunctions with no injuries reported. The property has an active maintenance history with numerous permits issued for various improvements, indicating ongoing investment in building maintenance and upgrades. Recent 311 calls (2023-2024) primarily concern external issues such as tree maintenance and sidewalk conditions, though these are not directly related to building performance.
