411-413 40th Ave, San Francisco, CA 94121

The property at 411-413 40th Avenue in San Francisco's Outer Richmond district is a one-story, 1926 multi-family residential building containing two units, currently owned by Leslie T & Betty Y Tsang. Significant improvements to the building were undertaken in 2008, including extensive renovations of both units involving kitchen and bathroom remodels, water heater and furnace updates, and electrical system upgrades.

These renovations, which cost approximately $100,000 in total, were completed successfully and included the addition of a bathroom in the second-floor unit and comprehensive upgrades to lighting, wiring, and plumbing systems. More recently, in December 2024, there were multiple service calls regarding urban issues in the immediate vicinity, including reports of garbage and debris, tree maintenance, and street lighting concerns, though these are primarily related to public areas rather than the building itself.

Notably, a fire code violation was recorded in December 2019, though the disposition indicates it was addressed on the same day. Earlier building maintenance records show previous roofing work completed in 1990 and 2000, and a garage ceiling drywall installation attempt in 2006 which ultimately expired without completion. The most recent address-related modification occurred in 2008 when an additional address was requested for the second unit, suggesting efforts to clearly delineate unit designations for administrative purposes.
