3-5 Sonoma St, San Francisco, CA 94133

The three-story, three-unit multi-family residential building at 3-5 Sonoma St in Telegraph Hill, owned by the Kwong Family Trust, was constructed in 1906 and has undergone several significant improvements over its lifetime. Most notably, in late 2020 and early 2021, the building received a comprehensive fire safety upgrade with the installation of a new Silent Knight fire alarm system, including multiple smoke detectors, pull stations, monitor modules, horn strobes, and sounder horns, at a cost of approximately $18,264.

Earlier renovations included bathroom remodels and sheetrock work in 1994-1995 across multiple units, as well as exterior improvements such as stucco application and vinyl siding installation. The building's safety record shows responsiveness to concerns, particularly in August 2005 when there was an issue with egress obstruction at the fire escape drop ladder, which was promptly addressed and abated within two weeks.

While there have been several 311 calls related to the property's vicinity since 2018, including reports of sewage backup and street cleaning issues, these are primarily external concerns unrelated to the building's structural integrity or internal systems. The most recent municipal service request, as of January 2025, involves a report of human waste or urine on the street, though this appears to be an exterior maintenance issue rather than a building concern. The property has maintained active compliance with housing inspections, with all routine inspections being properly addressed and closed.
