600 Oak St, San Francisco, CA 94117

The 18-unit apartment building at 600 Oak Street in Hayes Valley, owned by SF 600 Oak Street LLC, has undergone numerous improvements and repairs since its 1963 construction. Most recently, in September 2024, a tenant reported health concerns related to ventilation and odors following a renovation of Unit 11, which was completed in April 2024 at a cost of $65,000. The building has experienced recurring fire alarm system issues, with multiple violations and complaints in 2024 indicating persistent problems with the alarm systems despite some being marked as "Condition Corrected." A significant fire alarm upgrade was completed in January 2022 to meet code requirements.

The property underwent a mandatory soft-story seismic retrofit in 2018, demonstrating compliance with San Francisco's safety requirements. Several units have received modernizations including washer/dryer installations and kitchen/bathroom improvements, with notable work performed in Units 11, 15, 17, and 25. Infrastructure improvements include the installation of a solar PV system and an EV charger in 2013, though the solar permit expired.

The building's maintenance history shows attention to both unit-specific improvements and building-wide safety systems, though there have been some notable service interruptions, such as a three-month elevator outage in 2019 and multiple instances of water-related issues, including a flooding incident in 2021 that required inspection. Additionally, the property has added five ground-floor dwelling units as part of an ADU project permitted in 2016. While the building has had various complaints and violations over the years, most have been addressed and closed, though recent fire alarm system concerns suggest ongoing attention may be necessary for building systems.
