431-433 Frederick St, San Francisco, CA 94117

The 4-unit, 2-story multi-family residential building at 431-433 Frederick Street, owned by the Lockary/Thompson Family Living Trust, was constructed in 1908 and has experienced several significant maintenance events over its history. Most notably, in 2024, there is an open fire violation regarding sleeping area requirements that was cited in July.

The building underwent a complete roof replacement in 2005 at a cost of $9,500, which included 40-year composition shingles, and substantial structural work was performed in 2002, including stair repairs, deck removal, and handrail support improvements. A series of serious safety violations was documented in February 2002, including issues with stairs, smoke detectors, emergency egress, and various fire safety concerns, though all were abated by May 2002. The building has had three routine housing inspections since 1998 (1998, 2006, and 2011), while a significant complaint was filed in 2002 reporting multiple roof leaks, mold growth, window issues, electrical problems, and lighting failures.

More recently, in 2024, there was one documented fire violation regarding sleeping area requirements that remains open. The property has experienced routine systematic maintenance issues through the years, with several repairs to ensure safety and compliance with building codes, particularly in the early 2000s when multiple violations were addressed and resolved. The building's location is affected by external events such as the Outside Lands Festival in Golden Gate Park and urban maintenance activities, with recent complaints regarding noise from the festival and street cleaning matters being handled through regular city channels.
