Augrented Insights Report

The 8-unit, 3-story multi-family residential building at 410 23rd Avenue in San Francisco's Central Richmond neighborhood, owned by the James S Leong Revocable Trust, has undergone significant improvements and maintenance since its construction in 1922. Most notably, the building completed a mandatory soft-story retrofit in 2016, addressing seismic safety requirements with the installation of wood shearwalls, hold downs, special moment frames, and reinforced concrete foundations, with the work categorized as Tier 4.

Recent major improvements include a complete roof replacement in 2024 at a cost of $43,880 and a comprehensive fire alarm system upgrade in 2023 to meet current safety codes, demonstrating the owner's commitment to maintaining building safety standards. The property has a history of addressing various maintenance and compliance issues, including a bathroom remodel in Unit 2 in 2019, restoration of electrical wiring in 2017, and resolution of multiple building violations in 2002 related to fire safety systems and egress.

While there have been several complaints about the commercial portion of the property regarding vacant storefront ordinances between 2018-2020, these issues appear to have been resolved. Recent 311 calls show typical urban maintenance concerns including graffiti removal, pavement defects, and abandoned debris, with some issues still marked as open in 2023-2024. The building's historical records also show work from 1984 to bring the building up to code, reroofing in 1998, and various other improvements over the decades, indicating regular maintenance and upgrading of building systems.
