667-671 Greenwich St, San Francisco, CA 94133

The three-unit residential building at 667-671 Greenwich Street in North Beach is a three-story flats and duplex structure built in 1908 and currently owned by the John & Lai Fong Yee Revocable Trust. The building has undergone several significant improvements over the past few decades, with the most recent major renovation occurring in 2017, which included a kitchen and bathroom remodel, along with plumbing and electrical upgrades to meet current code requirements.

Historical records show previous substantial work in 1996 involving kitchen and bathroom remodeling, as well as structural modifications including beam work and the addition of a fireplace. The building has experienced some maintenance and safety concerns over the years, most notably a cluster of violations documented in December 2005 related to building safety and fire requirements, including issues with wood stairs, smoke detectors, and fire extinguishers, all of which were abated by February 2006. A significant plumbing-related incident occurred in February 2012 involving sewage in a water meter box that affected multiple neighboring properties and required dye testing of drain lines.

More recently, there has been an ongoing pattern of street-level cleanliness issues outside the building, with multiple 311 calls between July and December 2024 regarding garbage, debris, and waste management concerns, though these appear to be external to the building itself. The building's compliance history indicates periodic routine inspections by Housing Inspection Services from 1999 through 2005, and it underwent a legalization process for a substandard lot split in 1948, which has been approved. While the property has faced various maintenance challenges over the years, recent records suggest that necessary repairs and upgrades were completed, though the recent frequency of sidewalk cleanliness issues outside the building is notable.
