674-678 Oak St, San Francisco, CA 94117

The three-unit, three-story multi-family residential building at 674-678 Oak Street in Hayes Valley, owned by Jennifer L Brown, was constructed in 1890 and has undergone several significant renovations and repairs over the years. Most notably, in 2020, water leakage damage required repairs to the rear exterior wall of apartment 676, involving the replacement of insulation and sheetrock at a cost of $2,000.

The building underwent major safety improvements in 2011-2012, including the installation of a fire sprinkler system for the garage floor and first-floor walkway ($15,000), significant electrical upgrades including a 300-amp service with four meters, and the installation of new electrical components throughout the building. During this period, multiple plumbing and electrical permits were issued and completed, suggesting a comprehensive modernization of the building's systems. The property has experienced several concerning incidents, including a fire in 2006 (contained to one area, with no civilian injuries reported), multiple building code violations in 2008-2010 related to unsafe conditions and excavation work, and a period of blight in late 2008 with security concerns.

Recent maintenance issues have included problems with the side sewer vent cover (reported September 2024) and ongoing noise complaints (July 2024). The building's history shows active management and response to maintenance issues, with most building violations being addressed and resolved, though some recent 311 calls remain open. The property has undergone significant improvements since its construction, with recent repairs focusing on modernizing systems and addressing maintenance issues, though periodic problems with security and maintenance have occurred throughout its history.
