452 Oak St, San Francisco, CA 94102

Located in Hayes Valley, 452 Oak St is a 12-unit, 3-story multi-family residential building constructed in 1900 and currently owned by the Iveli Thomas Estate. The property has undergone several significant improvements over the years, including a completed soft-story retrofit in 2017 ($40,000), voluntary seismic improvements in 2012 ($37,300), and various plumbing upgrades such as tankless water heater installations in 2012 and 2008. Multiple fire safety system violations have been recorded and addressed between 2017 and 2023, including issues with alarm systems, sprinklers, and extinguishers, with the most recent violation being issued in March 2023.

The building has a history of maintenance and safety concerns, including a notable 2013 complaint about leaking ceilings, water intrusion, and inadequate trash receptacles, though many of these issues appear to have been resolved through subsequent repairs and inspections. Recent years have shown continued attention to building maintenance, including fence repairs in 2022 and electrical system upgrades in 2019. The property underwent unit renovations between 2006-2008, improving living conditions with kitchen upgrades in multiple apartments. Several routine safety inspections have been conducted, with the most recent being in 2019.

A 2019 incident involving feces in the shared laundry area raised sanitation concerns, though this appears to have been addressed. The building underwent significant planning processes for lot subdivision, with multiple approvals granted for variances and conditional use applications. While there have been recurring fire system violations, most have been promptly addressed, and the building has achieved compliance with various safety requirements over time. Recent 311 calls from 2024 indicate ongoing issues with garbage and debris management in the vicinity of the property, though these are primarily external to the building itself.
