1125-1129 Masonic Ave, San Francisco, CA 94117

The 1125-1129 Masonic Avenue property is a 1-story multi-family residential building located in the Haight Ashbury neighborhood, currently owned by the Chiu Family Trust since 2013. Originally built in 1925 as a two-unit structure, the building underwent significant modifications in 2005-2008, including a permitted conversion to three units, with associated plumbing and electrical upgrades.

The electrical system received a comprehensive overhaul in March 2008, including installation of 50 lights, 50 switches, 110 receptacles, and complete rewiring with 200-amp service. Prior to these renovations, the building experienced some maintenance issues in 2003, including plumbing problems that were promptly addressed, and foundation work was performed in 2005 costing $7,500. The building's recent history (2024-2025) has seen multiple maintenance and cleanliness issues in the surrounding area, including several instances of garbage and debris concerns, sidewalk graffiti, and parking enforcement calls, though these are primarily external to the building itself.

Between 2009 and 2023, there have been four recorded fire incidents, including an electrical equipment issue, a toxic condition, a lockout situation, and a contained trash fire, though none resulted in civilian injuries. A routine housing inspection was conducted in 2007 and a fire alarm system issue was resolved in November 2009. The property has undergone various planning processes, including variances for unit exposure and the addition of a lightwell and fire escape ladder, demonstrating ongoing compliance with safety and regulatory requirements.
