1718-1720 48th Ave, San Francisco, CA 94122

The two-unit residential building at 1718-1720 48th Avenue in San Francisco's Outer Sunset neighborhood is a two-story flats and duplex structure built in 1924, currently owned by Philip Gok Lieu. The property has undergone several significant improvements over the years, with the most recent major renovations including kitchen floor tiling and cabinet work in 2013, and the installation of vinyl siding on the back sides of the building in 2011.

In December 2018, the building experienced a cluster of violations related to interior maintenance, including issues with paint condition, kitchen cabinets, weatherstripping, and the need for carbon monoxide and smoke alarm compliance - all of which were successfully abated by February 2019. The property has seen ongoing maintenance attention, with permits issued for street space and sidewalk repairs over the years, including the most recent parking-related enforcement in March 2024.

Historical improvements to the building include the addition of a study room and toilet room in 1989, which suggest continued adaptation of the space to meet modern needs. The most recent open issue pertains to a pavement defect reported in August 2023, though this appears to be a street-related matter rather than an immediate building concern. While the 2018 violations indicated some maintenance challenges at that time, the prompt follow-up and resolution suggest proactive property management since then, though potential tenants should be aware of the building's age and history of requiring periodic maintenance updates.
