1425-1427 Oak St, San Francisco, CA 94117

The two-unit residential building at 1425-1427 Oak Street in the Haight Ashbury neighborhood is a two-story flats and duplex structure owned by the Dietrich-yee Family Living Trust and was constructed in 1900. The property has undergone significant improvements in recent years, particularly in 2016, when major work was completed including a $60,000 garage remodel with half bath addition, second floor kitchen renovation, and hallway lighting upgrades, along with $18,860 reroofing work. Important safety upgrades were implemented in 2014 with voluntary strengthening work including partial foundation replacement and installation of new structural components costing $16,000.

The building's systems have seen substantial modernization, with complete electrical rewiring and plumbing updates in 2016, including kitchen water recoppering and new bathroom facilities installation. The property has received regular maintenance and upgrades over the years, including an underground service conversion to a 200A system in 2004, though some permits from the late 1980s related to foundation work expired without completion. Recent events around the building have primarily consisted of municipal service calls, including multiple reports of abandoned vehicles and encampment-related issues in the vicinity between 2023 and 2024.

These external matters, while recorded, do not directly reflect on the building's condition or maintenance. A single fire incident was recorded, but was categorized as a false alarm with no civilian injuries reported. The building's most recent approved planning work includes window modification and interior improvements, along with the addition of a half bath in the garage area, suggesting ongoing commitment to property enhancement and maintenance.
