535-539 Guerrero St, San Francisco, CA 94110

The three-unit multi-family residential building at 535-539 Guerrero Street in Mission Dolores, owned by Yue Chok Wong Fmly Cr Shltr, was constructed in 1924 and is classified as a Flats & Duplex structure with two stories. The property has undergone significant recent improvements, with substantial renovations completed in March 2024 including comprehensive kitchen and bathroom remodels, electrical upgrades, and plumbing work totaling $64,000. These improvements encompassed new electrical wiring, additional bedroom outlets, and extensive kitchen and bathroom fixtures. Prior to this, in September 2023, the electrical system was notably upgraded with the installation of a new subpanel to replace an older fuse box system, representing a significant safety improvement.

The building's maintenance history shows attention to basic infrastructure, with a complete reroofing project undertaken in 2007 costing $6,000. The property has faced several regulatory inspections and violations, most notably in February 2008 when a routine inspection identified multiple safety issues including the need for fire extinguisher maintenance, seismic bracing of the hot water heater, and installation of smoke detectors near enclosed stairs. These violations were all promptly addressed and abated by March 2008. The building has undergone three routine apartment inspections between 2002 and 2010, all of which were satisfactorily resolved.

Recent activity around the property includes several 311 calls from 2014 to 2025 concerning exterior maintenance issues, though none indicate structural or safety concerns. The most recent building-related infractions include a report of graffiti (March 2024) and a tree maintenance issue (November 2023), both of which are currently open cases. A single fire incident was recorded, classified as a false alarm with no civilian injuries. The comprehensive recent renovations, including the substantial electrical upgrade and kitchen/bathroom modernization, combined with the prompt resolution of past violations, suggest active management of the property's maintenance needs. The building's historical records show regular inspections and prompt address of identified issues, though the age of the building (nearly 100 years) and its subsequent modifications suggest ongoing maintenance and monitoring will remain important for resident safety and comfort.
