4272-4280 23rd St, San Francisco, CA 94114

The 9-unit, 3-story multi-family residential building at 4272-4280 23rd Street in Noe Valley, built in 1913 and owned by Daniel Rabb, has undergone several significant improvements and faced various challenges over recent years. Most notably, the property completed a mandatory soft-story seismic retrofit in 2017 at a cost of $135,000, demonstrating compliance with San Francisco's seismic safety requirements. The building has seen substantial unit improvements in 2021, including bathroom remodels in Units B and C, with associated plumbing and electrical work totaling approximately $30,000. A reroofing project was also completed in 2021 for $33,800.

The building has experienced recurring maintenance issues that have impacted tenant quality of life. Most recently, in 2024, there was a complaint about 9 weeks without heat in the building. In 2018, multiple complaints were filed regarding mold, rotting, and drainage issues in the light well affecting Units 1 and 2, though these were eventually resolved. Historical violations from 2000-2007 included various interior maintenance issues such as water damage, plumbing problems, and lead paint concerns, all of which were abated by March 2007. The building has undergone regular maintenance and inspections, including fire safety checks for extinguishers which have generally shown "Condition Corrected" or "No Merit" findings.

The property has a documented history of parking-related issues in the area, with multiple blocked driveway complaints in recent years (2023-2024). While these are not directly related to building conditions, they do affect overall property accessibility. The most recent tenant buyout occurred in November 2021, involving 2 tenants at Unit 4274 for $22,500. The building's maintenance history shows a pattern of addressing both urgent repairs and planned upgrades, with most recent work focusing on individual unit improvements and building-wide maintenance systems. The most recent significant building-wide improvements (roofing, seismic retrofit) demonstrate ongoing investment in the property's structural integrity and safety systems, though some recurring maintenance issues suggest there may be ongoing challenges with building systems and moisture management.
