811 Diamond St, San Francisco, CA 94114

811 Diamond Street is a two-story, multi-family residential building located in Noe Valley, containing four units and constructed in 1975. The property has undergone several significant maintenance and improvement works, including a complete reroofing project in 2013 costing $13,000, and substantial decking renovations in 2006 which involved replacing waterproofing materials and installing new double-pane sliding doors on two rear decks measuring 4' x 18' each.

The building's safety systems received attention in late 2002, when a routine safety inspection identified multiple fire safety deficiencies, including the need for smoke detectors in the lobby, directional signs, and fire extinguisher maintenance; all of these violations were promptly addressed and abated by January 22, 2003. While a blocked exit complaint was filed in August 2007, it was determined to have no merit by September of that year. Recent history shows minimal major issues within the building itself, though there have been some maintenance matters and neighborhood incidents nearby, including reports of illegal postings (2021), and two separate reports of abandoned vehicles (2014) in close proximity to the building.

The property underwent a routine safety inspection by Housing Inspection Services in January 2012, which was resolved on the same day. The building's documented history indicates that while there were significant fire safety concerns in late 2002, these were resolved in a timely manner, and no similar violations have been recorded in the past 20 years. The most recent building improvements and routine inspections suggest that the property has been maintained in compliance with safety requirements since the early 2000s.
