1327-1329 Baker St, San Francisco, CA 94115

The two-unit residential building at 1327-1329 Baker Street in Lower Pacific Heights is a two-story flats and duplex structure built in 1900, currently owned by Susan C. Thadani. The property has undergone several significant improvements over the past decade, with the most recent being an electrical upgrade to a new 200-amp service in January 2025.

Notable modernization work includes a voluntary seismic upgrade of the first floor completed in 2019, installation of a combi boiler with radiant heating in 2020, and a bathroom remodel in 2021. The building has maintained attention to safety and infrastructure, as evidenced by the replacement of the north property line retaining wall in 2012 and the removal of outdated knob and tube wiring in 2015. The property has experienced some maintenance issues, including a sewer repair with trench drain installation in 2010 that was initially completed without proper permits, though this violation was promptly resolved within five days.

Historical records show earlier improvements from the 1980s and 1990s, such as kitchen and bathroom remodels and reroofing work. There have been several 311 calls related to the property's vicinity, including issues with a blocked sidewalk in 2020, a collapsed sidewalk due to a city tree in 2018, and a damaged tree requiring removal in 2017, though these were municipal rather than building-specific concerns. The building's maintenance history suggests regular upkeep and modernization efforts, particularly in recent years, focusing on both aesthetic improvements and essential system upgrades.
