643-645 Greenwich St, San Francisco, CA 94133

The property at 643-645 Greenwich Street is a four-story multi-family residential building constructed in 1907, currently owned by WW-DY LLC. The building has undergone significant renovations over the years, with major work completed in 2002-2003 including the addition of two stories, garage modifications, and a comprehensive electrical upgrade featuring new lighting, switches, receptacles, and safety systems. A notable roof deck expansion was completed in 2019, increasing its size from 142 to 415 square feet.

The building's safety systems were upgraded in 2005 with the installation of an overhead and underground N.F.P.A. 13 fire sprinkler system. Recent activity at the property has shown some concerns regarding resident experience, particularly in 2024, with multiple noise complaints (including excessive noise and amplified sound electronics) and several reports of blocked driveways, though officers were often unable to locate the offending vehicles.

There have also been instances of street cleaning issues and an encampment matter reported in 2024. The building's maintenance history includes termite repair in 2000 and various improvements to living spaces, including kitchen remodeling in 2000 and recent modifications to windows in 2021. Open permits in 2024 related to noise and parking issues suggest ongoing neighborhood interaction challenges.
