425 39th Ave, San Francisco, CA 94121

The 5-unit, 2-story apartment building at 425 39th Ave in San Francisco's Outer Richmond neighborhood, owned by Jeffrey & May Kool Survivor, has undergone several significant maintenance and safety improvements since its construction in 1960. Most notably, the building completed its mandatory soft story retrofit in 2018, achieving compliance with San Francisco's seismic safety requirements. Recent infrastructure work includes dry rot repairs at the rear of the building in 2019, window replacements in 2018, and multiple roofing projects in 1990, 2004, and 2016.

The building experienced multiple fire safety violations in 2003, including issues with the fire escape ladder, sprinkler systems, and alarm system, though all were resolved by April 2003. A significant plumbing issue occurred in 2004 involving leaks affecting walls, windows, ceilings, and storage areas, which was addressed by February 2005. The most recent concerns at the property include a sewage backup incident from the side sewer vent in December 2024, which has been resolved.

The building has experienced three fire-related incidents on record: an alarm malfunction, a gas leak, and an electrical issue, though none resulted in civilian injuries. Recent 311 calls indicate ongoing maintenance needs in the surrounding area, including landscaping and street cleaning matters. The property was subject to a tenant buyout at the adjacent 443 39th Avenue address in 2022 for $55,900 affecting 2 tenants, though this was for a different building on the same street. The building's maintenance record shows regular upkeep and compliance with major safety requirements, particularly the critical soft story retrofit program.
