450 Peralta Ave, San Francisco, CA 94110

This two-unit residential building, located at 450 Peralta Ave in Bernal Heights, was constructed in 1967 and is currently owned by the K P Mauzey 2007 Trust. The property has undergone several significant maintenance and improvement projects over the years, including a water supply line replacement from the meter to the house in 2016, removal and replacement of roofing in 2004 and 1990, and deck repairs at the upper level in 1997.

One notable incident occurred in 2005 when unauthorized construction of a steel stair with wood platform and staircase at the rear of the building led to multiple building violations and abatement proceedings, which were finally resolved in 2010 when a $15,000 permit was obtained to legalize the previously unauthorized work. The building has experienced some maintenance issues that have affected resident comfort and safety, including a 2017 complaint about a broken downspout causing water leakage and debris issues.

More recent records from late 2024 show multiple infrastructure and maintenance matters in the vicinity, including tree maintenance concerns, driveway blocking incidents, and various public works requests. There were also several fire safety violations recorded in late 2005 related to a fire hazard, though these were subsequently closed. While most historical building issues have been addressed through proper permits and corrections, the property has experienced various maintenance challenges typical of a residential building of its age and configuration.
