550-552 43rd Ave, San Francisco, CA 94121

The property at 550-552 43rd Avenue in San Francisco's Outer Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1947, currently owned by the Wong Wilma Y K Trust.

The building has undergone several significant renovations and maintenance projects over the past few decades, with the most recent major work occurring in 2015 when four front facade windows were replaced with fiberglass windows at a cost of $3,000. The building underwent substantial interior improvements in 2012-2013, including a comprehensive kitchen and bathroom remodel (2012) featuring new countertops, cabinets, sink, appliances, tiles, vanity, and paint (with associated plumbing and electrical work), followed by a second-floor kitchen remodel (2013) and bathroom updates including new plumbing fixtures.

The property's maintenance history shows attention to basic infrastructure, with termite work completed in 1998, and while a reroof permit was filed in 1993, its status is listed as expired. The building has received proper attention to both safety and comfort features, with multiple permits showing systematic updates to plumbing, electrical systems, and basic facilities over the years, with all recent work appearing to be completed properly according to permit records.
