422 23rd Ave, San Francisco, CA 94121

The property at 422 23rd Avenue is a two-story, four-unit multi-family residential building located in San Francisco's Central Richmond neighborhood. Built in 1922 and currently owned by Wilkie H. and Nancy K. Wong, this apartment building has undergone several significant changes and faced multiple regulatory challenges throughout its history.

In 2002-2003, the building experienced major violations related to fire safety and security, including issues with combustible storage, fire proofing, and the unauthorized installation of additional dwelling units on the ground floor. These violations required the installation of automatic fire sprinklers and brought about concerns regarding inadequate lighting, ventilation, and ceiling height. All of these violations were abated by February 2003, along with associated building modifications including electrical work. Since those initial issues were resolved, the building has undergone various improvements including reroofing work completed in 2004 and window replacements in 2003.

More recent history shows ongoing maintenance efforts with street space and sidewalk repairs in 2010. Recent 311 calls related to the property have primarily concerned parking enforcement issues, with multiple reports of sidewalk parking violations between 2020-2022, though these are external to the building's operations. A notable health-related complaint regarding building infestation was filed in September 2021 and transferred to the Department of Public Health's Environmental Health division. The building's permit history shows regular maintenance and upgrades typical for its age, though the window replacement and several electrical work permits from 2003 show as expired in the records.
