1451 Silver Ave, San Francisco, CA 94134

The two-unit residential building at 1451 Silver Avenue in the Portola neighborhood, owned by Xu Rong Juan, is a 2-story flats and duplex structure built in 1900. The property has undergone several infrastructure improvements over the past two decades, including window replacements with vinyl windows in 2002, electrical service upgrade to 100 amps in 2011, and a gas houseline extension in 2013, all of which were properly documented through building permits.

The building experienced maintenance issues in early 2019, with two separate complaints about the inadequately maintained building exterior that were subsequently resolved. The property's more recent history (2022-2024) has been marked primarily by challenges related to the surrounding infrastructure, particularly the sidewalk and street conditions. There have been multiple reports of pavement defects, with the most recent being an open case from August 2024, and an earlier sidewalk defect report from October 2024 that was closed as the defects did not meet required standards.

Historical records from 2017 show several complaints about raised and uneven sidewalk squares, though these were either canceled or resulted in no action being required. The building's location has also been subject to occasional neighborhood issues, including a parking enforcement call in 2022 that resulted in no action and a resolved encampment removal in 2019. All documented permits and complaints show proper channels were followed for reporting and resolving issues, with most structural improvements being professionally addressed through appropriate permits.
