639-641 39th Ave, San Francisco, CA 94121
The property at 639-641 39th Avenue in the Outer Richmond is a two-unit, two-story residential building constructed in 1949, currently owned by Lauren Ito. The building has undergone several significant renovations over the past two decades, including a substantial $120,000 remodel in 2015 that updated both kitchens and six bathrooms to comply with current regulations.
More recent work includes a $9,500 stair repair in the light well completed in 2020, though there remains an active housing inspection complaint filed in August 2017 regarding peeling paint with lead concerns at the back of the building. The building's exterior and accessibility features have received attention over the years, with balcony replacements completed in 2003 costing $9,280, and an attempted (but ultimately expired) permit for rear deck additions at both units in 2003 valued at $20,000.
The property has experienced persistent parking-related issues, as evidenced by numerous 311 calls between 2021 and 2024, primarily regarding driveway blocking. An interesting note is the building's rear yard variance application for the deck, which was eventually approved under the name of developer Luke Sheridan from Gensler. The property has maintained good compliance with building codes, with all documented permits marked as complete, and all electrical work was inspected and approved, including considerable electrical upgrades in 2003 that installed multiple circuits, lights, switches, and receptacles throughout both units.
