764-766 Chestnut St, San Francisco, CA 94133

The two-unit residential building at 764-766 Chestnut Street in Russian Hill, owned by the John E Wai 1981 Living Trust, has undergone substantial renovations and faced several maintenance challenges since its construction in 1907. Most recently, in early 2025, there have been ongoing structural modifications including the addition of footings below the exterior wall along the east property line, along with bathroom renovations in the downstairs unit costing approximately $28,192.

In late 2024, significant structural work was performed including the replacement of a moment frame with plywood shearwall at the rear wall and additional interior stair strengthening. Notable concerns have emerged regarding water issues, with multiple leak complaints reported in early 2024, including a potential mold problem that led to a tenant's departure. There have also been historical compliance issues, including a 2022 violation for a protruding structural beam on the front porch, which was subsequently addressed.

The building has undergone multiple comprehensive renovations over the years, including complete remodels of both kitchens and bathrooms in 2019 and 2021, and has had various permits issued for electrical and plumbing work. A planning record from 2022 shows a requirement to relocate the front door to meet entry requirements, though this appears to be part of ongoing improvements to the property. The most recent complaint as of December 2024 relates to the possible use of the neighbor's property line wall for construction support, which is currently active.
