283 20th Ave, San Francisco, CA 94121

The 6-unit, 2-story multi-family residential building at 283 20th Ave in the Central Richmond neighborhood, owned by Elaine Richards, was constructed in 1926 and has undergone several significant improvements over the past decades. Most notably, the building completed mandatory soft-story retrofit work in 2019 (Tier 3) to strengthen wood shear walls and comply with seismic safety requirements, with the work's cost amounting to $65,000. Recent maintenance includes roofing work and siding replacement in 2023, with a project value of $9,800.

Unit #5 received substantial renovations in 2019, including a remodel of living spaces, window modifications, kitchen updates, and electrical system improvements with a combined cost exceeding $28,000, as well as plumbing upgrades involving water line relocation. The building's maintenance history shows attention to critical infrastructure, with a complete sewer line and trap replacement in 2012, though there were some earlier issues that required attention. In 2003, the building faced multiple violations related to ventilation, fire safety, and alarm systems, though these were all resolved by September 2003.

A 2005 complaint regarding insufficient heat was similarly addressed within one day. An annual inspection in 1995 and a routine inspection in 2009 showed normal regulatory oversight. More recently, the property experienced typical urban maintenance issues, as evidenced by 311 calls for street cleaning in 2021 and 2024, which were resolved promptly.
