451 4th Ave, San Francisco, CA 94118

The two-unit multi-family residential building at 451 4th Avenue in San Francisco's Inner Richmond district, owned by Ekeh Innocent & Agatha, was constructed in 1900 and has experienced several significant maintenance issues over the past decades. Most notably, in 2016-2017, the property faced multiple violations that escalated it to "nuisance" status, including unaddressed repairs to stairs, corner trim, and the presence of rubbish, along with safety concerns regarding fire hazards, inadequate lighting, and missing smoke detectors.

These violations were ultimately resolved by February 2017 through various repairs and compliance measures, including staircase repairs costing $250. Recent history shows ongoing maintenance challenges, with complaints in early 2018 regarding water issues, including a leaking backdoor well and plumbing problems.

The building's maintenance record reveals attention to various structural and safety concerns over the years, including termite treatment in 1986, ground floor alterations in 1987, and various interior improvements in the 1990s. Historical complaints from 2002 indicated serious issues including lack of heat, plumbing problems, and environmental concerns, which were addressed at that time. While recent years show fewer building-specific complaints, there have been multiple parking enforcement issues in the vicinity, with several citations issued between 2021-2022 for vehicles blocking sidewalks and driveways, though these are external to the building's condition and operation.
