1636-1638 Leavenworth St, San Francisco, CA 94109

The two-unit residential building at 1636-1638 Leavenworth Street in Nob Hill, owned by Shirley Lim, is a two-story flats and duplex structure built in 1909. The property has undergone several significant maintenance and improvement projects in recent years, most notably complying with physical inspection report #CC-8467 in 2021, which involved electrical updates (installing GFCI on roof and light blink space on panel) and plumbing corrections.

In 2020, the building benefited from the replacement of nine street-facing wood windows on the building's front facade. The property has seen substantial interior improvements between 2018-2020, including two bathroom remodels, kitchen upgrades, and the installation of a tankless water heater and new HVAC systems (two furnaces and AC) in early 2019. A notable building complaint was filed in March 2019 regarding water intrusion and potential mold around window frames, though this complaint is currently listed as not active.

The property has generated multiple 311 calls between 2019-2024, primarily related to street cleaning issues, though these appear to be exterior maintenance matters rather than building-specific problems. The most recent building improvements suggest ongoing maintenance and modernization efforts by the current ownership, with completed permits showing proper adherence to regulatory requirements. The building's recorded history shows no major safety incidents or violations since the 2019 water-related complaint, and recent improvements indicate active management of the property's maintenance needs.
