631 5th Ave, San Francisco, CA 94118

The two-unit residential building at 631 5th Avenue in San Francisco's Inner Richmond neighborhood is a two-story flats and duplex structure built in 1911, currently owned by Mona M. Liang. The building has maintained basic structural integrity over the years, with major maintenance work completed in 1989 including stucco replacement, dry rot repair, and the installation of forty aluminum windows.

The property also underwent a reroofing project that same year, all of which have been marked as complete in the building permit records. Two sidewalk and street space repair permits were issued in October 2007, though the costs were noted as minimal ($1.00). A more recent infrastructure issue was addressed in November 2024, when abandoned furniture was reported and successfully removed from the vicinity.

The most significant pattern of concern relates to parking violations, with six documented incidents of sidewalk parking between 2020 and 2023, mostly involving the same vehicles (a dark gray Lexus sedan and a black Audi SUV). While most of these cases were either unable to be located or resulted in an issued citation, they do indicate ongoing challenges with parking compliance in the area. In 2014, there were three separate tree-related incidents recorded on the same day, all involving damaged or vandalized trees requiring maintenance. Return to space permits from 2007 and other routine maintenance represent the building's documented history of care for the property, though these are relatively minimal compared to the earlier improvements made in 1989.
