138-140 Bernard St, San Francisco, CA 94109

The two-unit residential building at 138-140 Bernard Street in Nob Hill, owned by David Fong and Lina Chen, is a two-story flats & duplex structure dating back to 1916. The property has undergone significant renovations over the past two decades, with major work completed in 2008-2010 including comprehensive kitchen and bathroom remodels in both units, and the installation of new bathrooms, kitchen relocations, and various structural improvements such as new shear walls and deck extensions.

The electrical and plumbing systems were also substantially upgraded during this period, with detailed records showing extensive new installations including lighting, appliances, and safety features such as smoke detectors. More recent maintenance includes a reroofing project in 2014 costing $10,800.

The building faced a sewage discharge vent issue in July 2024, which was promptly resolved by the PUC Sewer Operations team. While there have been some exterior maintenance matters recorded, including sidewalk blocking and general street cleaning issues in 2017-2018, these were primarily municipal service matters affecting the public right-of-way rather than direct building or resident concerns. The property's extensive renovation history suggests significant investment in modernizing and maintaining the structure over the years, with all major work appearing to have been properly permitted and documented.
