3806 18th St, San Francisco, CA 94114

The three-unit residential building at 3806 18th Street, located in the Eureka Valley/Dolores Heights neighborhood, is a three-story flats/duplex structure built in 1908 and currently owned by the Chan Family Living Trust. The property has experienced several significant maintenance and safety issues over its history, with the most notable event being a fire incident that occurred in 2001 requiring $45,000 in repairs to the roof, kitchen walls, and interior finishes.

That same year, the building underwent rear stair repairs costing $12,000, though those permits are now expired. In 2014, plumbing work was completed, involving the replacement of approximately 15 feet of water line.

A cluster of building violations was documented in April 2005, including issues with combustible storage, interior surfaces (such as damaged walls and ceilings), window glazing, and sanitation concerns, though all were abated by June 2005. More recently, there have been several 311 calls regarding street infrastructure and parking issues near the property, including damaged sewer vent covers and parking violations, with the most recent cases occurring in 2023-2024. The building's maintenance history shows attention to basic repairs, including cement floor repairs in the garage (1986) and elsewhere (1993), but also indicates periods of deferred maintenance requiring correction through housing inspections.
