557-559 5th Ave, San Francisco, CA 94118

The two-unit residential building at 557-559 5th Avenue in the Inner Richmond neighborhood is a two-story flats and duplex structure built in 1909, currently owned by the Wang-Schiffner Family Trust.

The property has undergone several significant improvements over the past decade, with the most recent major work being the installation of a new 1-inch main water line from the meter to the house in September 2019. Prior to this, substantial renovations were completed in 2014, including a comprehensive kitchen remodel and the conversion of an existing water closet and pantry into two full bathrooms on the top floor, featuring new skylights and window replacements; this work was accompanied by electrical upgrades for lighting, switches, receptacles, and appliance installations, as well as plumbing modifications.

The building has received attention to maintenance issues as well, including dry rot repairs at a bay window in 2015 and a full reroofing project in 2012, demonstrating ongoing property upkeep by the owners. The only reported incident related to the property was a parking enforcement call in March 2021 regarding a vehicle on the sidewalk, which was responded to but the offending vehicle could not be located, though this was not directly related to the building's condition or management.
