625-631 Greenwich St, San Francisco, CA 94133

The property at 625-631 Greenwich Street is a 2-unit, 2-story multi-family residential building constructed in 1907, currently owned by Leonard Koren & Yoko Z Kato. The building has undergone several significant improvements, most notably the creation of a wine cellar beneath the garage area in 2001-2002, which was completed at a cost of approximately $49,000. The property has experienced two notable compliance issues related to fire safety systems, with multiple violations documented in December 2005 including problems with fire escape ladders, fire extinguishers, and emergency exit lights, though all were abated by January 2006.

More recently, plumbing improvements were made in 2017 with the installation of two emergency shut-off valves. The building's maintenance history shows consistent attention to roofing, with multiple permits issued in the late 1990s for repairs and replacements, though some permits show as expired. A significant renovation occurred in 1992 involving kitchen and bathroom remodeling, as well as modifications to the stair configuration. Recent activity at the property has primarily consisted of parking-related issues, with multiple 311 calls in 2024 regarding blocked driveways, though these are external to the building itself.

The property underwent a notable planning process to resubdivide the parcel into two lots, with variances approved for rear stairs and landings extending into the rear yard area, though this appears to have occurred prior to the current ownership's tenure. The most recent building improvements, including the 2017 plumbing upgrades, suggest ongoing maintenance of essential systems, though the age of the building means regular upkeep is to be expected. The property has undergone routine housing inspections in 2010 and 2005, with no active violations on record as of the most recent data. While the building has experienced multiple permit applications and modifications over the years, these appear to be typical for a structure of this age and configuration, with particular attention paid to both safety systems and resident amenities.
