660-664 8th Ave, San Francisco, CA 94118

The two-story multi-family residential building at 660-664 8th Avenue in San Francisco's Inner Richmond neighborhood was constructed in 1923 and contains 4 units. The building has undergone several significant improvements over the years, including a complete reroofing in 2011 costing $6,270, installation of new electrical sub-panels in 2010, and the conversion of an in-law kitchen to a laundry unit in 2005.

A notable renovation in 2002 involved merging a ground floor studio with an upstairs unit to eliminate an illegal unit, and a street space permit was issued in 2014. The property has undergone three routine housing inspections (2017, 2010, and 2002) by Housing Inspection Services, with the most recent inspection in March 2017 resulting in multiple violations that were abated by April 2017. These violations included issues with fire safety equipment, gas utility requirements, and the need for a carbon monoxide detector.

The building's maintenance history shows attention to both structural and safety systems, with electrical upgrades and roofing work performed in recent years. More recently, in late 2023, there was a reported infestation issue, as documented in a Department of Public Health complaint. The building has also experienced recurring issues with parking enforcement, particularly regarding blocked driveways and sidewalk parking, with multiple citations issued between 2019 and 2025, suggesting ongoing challenges with parking management in the vicinity.
