258-260 24th Ave, San Francisco, CA 94121

The three-unit residential building at 258-260 24th Avenue was constructed in 1989 and has undergone several significant modifications and improvements over the years, with substantial work occurring between 2015-2020. Most notably, the ground floor unit was legalized in 2015 under Ordinance 43-14, which required the installation of a comprehensive fire sprinkler system throughout the first floor ($9,000), along with monitoring systems ($3,500). The building has seen consistent maintenance and upgrades, including a 2020 rear wall siding replacement ($5,000) and a 2017 reroofing project ($10,000).

Several plumbing and electrical improvements were completed in 2018, including the installation of washer/dryer facilities, water lines, an electrical water heater, and a garage GFI outlet. The property experienced a significant compliance issue in 2013 when unauthorized modifications to unit #260's first right bedroom were reported, involving the installation of an oversized platform structure. This violation was addressed and abated by March 2014.

Other maintenance records show periodic issues with street cleaning, including reports of abandoned furniture and debris, as well as a sewage backup incident in September 2021 that was promptly resolved. The most recent fire incident recorded was a system malfunction with no civilian injuries. The building, managed by owner He Li Bin, has maintained active compliance with safety regulations and building codes, with all documented permit work completed successfully.
