4280 Folsom St, San Francisco, CA 94110

The two-unit multi-family residential building at 4280 Folsom Street in Bernal Heights, owned by Tommy Lam, was constructed in 1976 and has had limited significant maintenance records, with the only building permit on file being for a reroofing project completed in 1994. The property has faced multiple challenges in late 2024 and early 2025, with the most pressing issues being multiple reports of garbage and debris on nearby streets, including loose garbage, yard waste, and abandoned furniture, which were primarily addressed by Recology and Street and Environmental Services.

There have also been recurring encampment-related incidents reported between December 2024 and January 2025, with varying outcomes including some cases being cancelled or marked as invalid. The building has a documented history of fire safety inspections in 2019, resulting in multiple violations related to weeds, grass, and hoarding, though these issues were subsequently resolved.

Fire department records show several service calls to the area, including responses to carbon monoxide and smoke detector activations, water problems, and motor vehicle incidents, though none resulted in civilian injuries. Of particular note, during 2023, there were two tenant buyout offers recorded at a nearby address (4251 Folsom Street), with payments of $10,000 for 2 tenants and $30,501 for 3 tenants, though it's unclear if these are directly related to the building in question. The most recent maintenance record for the property remains the 1994 roofing work, and there are no current open building violations or permits on file as of October 2023.
