47 Castillo St, San Francisco, CA 94134

The two-unit residential building at 47 Castillo Street in Visitacion Valley is a 2-story flats/duplex structure built in 1949, currently owned by Lee Bun Hung. The property has undergone several significant improvements over the years, including a reroofing project in 2018 costing $8,250, and a rear stair replacement in 2002 for $450.

A notable issue occurred in 2000-2001 when a housing inspection revealed an unauthorized unit in the basement with serious safety concerns, including inadequate emergency egress and security bars presenting safety hazards; this situation was partially resolved through subsequent interventions. This pattern of unauthorized unit use was echoed in a 2013 complaint about a garage unit allegedly housing multiple occupants, though this complaint was quickly abated. The building's permit history shows construction-related work was conducted in the mid-1980s, specifically regarding interior non-bearing walls and bathroom construction, with follow-up permits issued to complete the work in 1987.

Recent activity around the property has primarily involved external issues rather than building-specific concerns, including multiple complaints about abandoned vehicles (2011), street light maintenance (2012), and a second-hand smoke complaint (2013). More recently, in September 2024, there were two complaints about driveway blockage, though these cases were deemed invalid as they lacked proper contact information for enforcement. While the recent history has shown fewer building-specific issues, the property's past violations regarding unauthorized units and safety concerns merit attention to the building's historical context.
