642 Peralta Ave, San Francisco, CA 94110

642 Peralta Avenue is a two-story, four-unit multi-family residential building located in Bernal Heights, constructed in 1960 and currently owned by Edgar Wong. The building has undergone several maintenance and safety compliance efforts over its history, with the most significant recent work occurring in 2015 when exterior repairs were completed to address wood dry-rot beneath windows, including the replacement of eight windows at the front of the building, at a cost of $25,000.

Earlier improvements include a 2003 electrical upgrade for underground conversion with 100-amp service, and in March 2001, the building underwent a routine housing inspection that revealed multiple safety code violations which were subsequently addressed and abated by June 27, 2001. These violations included the need for proper gas utility shutoff tools, fire safety improvements such as sprinkler systems and fire extinguisher maintenance, and security enhancements like self-closing exterior doors. The property has experienced various maintenance and service calls in recent years, with the most notable being a sewage backup incident in October 2024, though this was ultimately cancelled by the caller.

Other recent 311 calls predominantly relate to external issues such as parking violations, garbage concerns, and noise complaints, with a notable pattern of reports regarding abandoned vehicles and debris in the vicinity throughout 2024. A gas leak incident was recorded at some point in the building's history, though no civilian injuries were reported, and there was one combustible materials complaint in 2010 which was determined to have no merit. The building's history suggests regular maintenance and prompt attention to violations when they occur, with no active violations or complaints currently on record.
