531 43rd Ave, San Francisco, CA 94121

The property at 531 43rd Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Outer Richmond neighborhood, constructed in 1908 and currently owned by Alan W. and Evelyn F. Freebury.

The building experienced significant activity in 2003, including several permits for major maintenance work such as a complete reroofing ($7,300), bathroom renovations, electrical upgrades, and various legalizations of prior unpermitted work, including 17 window and 5 door replacements, and siding modifications. A notable violation was recorded in April 2003 regarding unauthorized construction of rear stairs and replacement of wood shingles with vinyl siding, which led to abatement proceedings that were finally resolved in April 2005. During this period, concerns were also raised about potential illegal dwelling units, including basements and unauthorized sewer line connections, though these were subsequently addressed.

The building's maintenance history shows regular upkeep, including bathroom ventilation installation in 2003, electrical work, and various repair projects throughout the years. More recent issues include a sewer backup incident in July 2019 and concerns about a collapsed sidewalk reported in August 2018, both of which were resolved by city services. The property's maintenance record suggests ongoing attention to building systems and infrastructure, particularly during the early 2000s when several unauthorized modifications were brought into compliance with building codes. The most recent activity recorded was a general service request in June 2023, which was successfully resolved by city services.
