52-54 Fair Ave, San Francisco, CA 94110

The two-unit residential building at 52-54 Fair Avenue in Bernal Heights, owned by Su Yang, is a two-story flats and duplex structure built in 1910. The property has undergone several significant upgrades and maintenance work over the past few decades, with the most recent major improvements occurring in 2019, including a service upgrade to 200 amps with two meters and an address modification to properly document both units.

Earlier improvements included a rear facade siding replacement with hardy plank in 2015, front window replacements in 2007, and a complete reroofing project in the same year. The building's historical maintenance record shows consistent upkeep, though there was one expired permit from 1998 for drywall and window work. The property has experienced some environmental and infrastructure incidents, with the most recent being a resolved case of human waste or urine on the premises in June 2024.

Previous issues include hazardous materials (glass) on the property in October 2015, a housing complaint transferred to the Healthy Housing & Vector Control Program in December 2014, and a reported missing side sewer vent cover in July 2014 that was found to have damaged the sidewalk. Of particular note is a tenant buyout that occurred on November 13, 2017, at 54 Fair Avenue, involving one tenant and a compensation amount of $17,000. The building's maintenance history suggests active management, with most permits marked as completed, though the property's location has faced some street-level environmental challenges as documented in 311 calls.
