1391-1393 33rd Ave, San Francisco, CA 94122

The property at 1391-1393 33rd Avenue in the Central Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1947, currently owned by the Annie Wai Ling Won Revocable Trust. The building has undergone several significant improvements over the past two decades, with the most recent major renovation occurring in 2018 when six Milgard white vinyl windows with a U-factor of 0.32 were installed in the rear of the building at a cost of $3,000.

Earlier improvements included reroofing work in 2002 (though this permit has since expired), and two related construction projects in 1998 that expanded the ground floor by adding rooms, including a bathtub and a closet. The building has experienced several maintenance and quality-of-life incidents in its vicinity between 2018-2020, though none directly related to the building's condition or safety.

These included three documented instances of sidewalk parking violations (resulting in one citation), a cancelled report of pavement defects, and an instance of graffiti on a fire police call box that was subsequently abated. The property has maintained an active permit history with documented improvements that suggest regular maintenance and updating of building systems, though the expired roofing permit from 2002 may warrant verification of whether this work was completed under a subsequent permit or as part of a later renovation.
