4186-4190 20th St, San Francisco, CA 94114

The property at 4186-4190 20th Street is a two-story, four-unit multi-family residential building with retail space, constructed in 1908 and currently owned by Wahhab Living Trust. The building has undergone several significant maintenance and compliance events over the past two decades, most notably a complete reroofing project completed in December 2024 costing $10,000. A major compliance issue occurred in 2004 when an unauthorized 8-foot structure was built on the roof, blocking neighbors' views; this violation was finally resolved in 2010.

The building has maintained regular housing inspections over the years (2001, 2007, 2011, 2014), with no violations found in the most recent routine inspection. Recent maintenance activities include electrical work related to signage in 2012, though an attempt to connect power to a 100-amp service in 2020 was cancelled. The building experienced some infrastructure issues in 2024, including a sewage backup incident in November that was promptly resolved by utility services.

The surrounding area has seen various municipal service interactions in 2024, including multiple reports of illegal postings, defaced signs, and a concerning damaged tree issue reported in July 2024. While these external issues don't directly impact the building's habitability, they provide context about the property's immediate environment. The property's maintenance record shows regular upkeep and prompt attention to violations when they occur, with no current active violations or complaints on file.
