658-660 5th Ave, San Francisco, CA 94118

The two-unit residential building at 658-660 5th Avenue in San Francisco's Inner Richmond neighborhood is a two-story flats and duplex structure built in 1907, currently owned by Kuang Liang Huang and Liang Cai. The property has undergone several significant improvements over the past two decades, with the most recent substantial renovation occurring between 2003-2004, including bathroom remodels, window replacements, interior painting, and comprehensive electrical upgrades such as installing multiple receptacles, switches, and a new sub-panel. These improvements were properly permitted and completed, demonstrating attention to compliance and modernization.

Earlier maintenance work included stairway reinforcement and wall re-stuccoing completed in 1989. The building's maintenance history shows some concerns related to exterior upkeep in the early 2000s, with complaints about peeling paint and potential lead-based paint issues filed between October 2002 and March 2003. However, these violations were ultimately abated by December 2008.

More recent history indicates no building-specific complaints or violations since 2008, suggesting improved maintenance protocols. The only reported issues in recent years have been unrelated to the building's condition, including three public space matters: an abandoned vehicle report in July 2024, and two street cleaning issues in 2016 and 2019, all of which were resolved by city services. While there was one open sidewalk blockage case in May 2022 involving a portable toilet, this was an external rather than building-specific issue.
