453 31st Ave, San Francisco, CA 94121

The two-story multi-family residential building at 453 31st Avenue in the Central Richmond neighborhood, owned by the Lam Living Trust, was built in 1960 and contains 10 units. The property has undergone several significant safety improvements over the past two decades, most notably completing a mandatory soft-story seismic retrofit in 2015 (Tier 3) at a cost of $100,000, and a $46,800 reroofing project in 2019. The building's exterior stair safety has been a recurring focus, with multiple repairs and enhancements documented between 1995 and 2015, including new rails installation, dry rot repairs, and work on the rear exterior stair.

Security improvements were implemented in 2006 with the installation of a security roll-up door and panic hardware. The building faced multiple safety violations in July 2003, including issues with fire safety systems and electrical wiring, though all were abated by August 25, 2003. There have been routine housing inspections, including an active case from October 2003.

More recent fire safety concerns were investigated in March 2019 (regarding extinguishers) and February 2013 (regarding alarm systems), both of which were found to have no merit. The property has experienced occasional maintenance issues in the surrounding area, as evidenced by multiple 311 calls, primarily regarding parking violations in the vicinity between 2018 and 2024, along with some street defect and sidewalk maintenance matters in 2017. Recent inspections show no active safety violations or complaints on record, suggesting the building is currently maintaining compliance with safety requirements.
