2256-2258 Pine St, San Francisco, CA 94115

The two-unit residential building at 2256-2258 Pine Street in Lower Pacific Heights, owned by Cheung D Michael, is a two-story flats and duplex structure built in 1900. The property has undergone several significant improvements over the years, with the most recent major work being a complete re-roofing project in 2016 costing $26,000.

The building has seen various infrastructure upgrades, including sewer pipe replacement and house trap installation under the sidewalk in 2009, though a furnace replacement permit from the same year expired without completion verification. Historical records show multiple proposed modifications in the 1980s and 1990s, including cancelled plans for basement parking conversion and second-story rear porch modifications, as well as completed horizontal additions in 1992.

The property experienced a sewage vent issue in September 2015 that was resolved by the PUC Sewer Operations. More recently, in 2020, there were minor municipal service calls regarding general street cleaning and tree maintenance in the vicinity of the property. Planning records indicate a notable improvement project involving the replacement of an existing covered porch with a new kitchen, which was approved and completed under Section 134 regulations, suggesting attention to both structural and functional improvements throughout the building's history.
