1656-1658 Sacramento St, San Francisco, CA 94109

The 13-unit, three-story apartment building at 1656-1658 Sacramento Street in Nob Hill, constructed in 1913 and owned by Au Yat-cheong & Ann Min-an, is undergoing significant improvements in 2024. The most recent notable work includes the installation of a new NFPA 13 fire sprinkler system, with associated permits issued in August 2024 at a cost of $52,280. The building is currently transitioning to add two accessory dwelling units (ADUs) at the ground floor, with plumbing and electrical permits issued in October 2023 for the installation of new bathrooms and kitchens for the ADU units.

Recent renovation history reflects substantial interior upgrades across multiple units between 2021-2022, including kitchen relocations, bathroom rehabilitations, and washer/dryer installations in units 1, 3, 4, and 7. The building has faced various maintenance and safety challenges over the past two decades. A series of fire safety violations, including alarm system maintenance issues in 2023, 2017, and 2016, and sprinkler system concerns in October 2024 (though marked as "No Merit"), indicate ongoing fire safety system attention.

Historical building violations from 2002 included issues with fire extinguishers, fire escape ladders, electrical outlets, and lead paint hazards, though these were all abated by November 2004. Recent complaints from 2023 raised concerns about construction conditions, including exposed rebar and wiring, though this appears to be an active issue requiring further monitoring. The building achieved compliance with the soft story retrofit program (Tier IV) in 2024, and while there have been multiple service calls regarding various building systems and street conditions near the property, these have generally been resolved through appropriate channels. The property has a history of unauthorized short-term rental activity that was investigated and resolved in 2019.
