645-647 Clement St, San Francisco, CA 94118

The property at 645-647 Clement Street is a two-story mixed-use building constructed in 1900, containing a ground floor grocery market and residential units above. The building has undergone several significant renovations, with the most recent major work occurring in 2011 when the grocery market underwent substantial remodeling ($85,000) including equipment changes, structural modifications, and plumbing upgrades, particularly converting from a 2-compartment sink to a 3-compartment sink configuration. The residential portion received extensive improvements in 2004, including window replacement, electrical rewiring, and new fixtures. The property has experienced some notable issues in recent years, particularly in 2019 when there were multiple complaints about sewer gas smells in the stairwell area, and standing water concerns were reported.

More recent building-related concerns include a 2022 complaint about an unpermitted security metal door installation. The property has maintained its grocery use status under the Inner Clement Neighborhood Commercial District regulations, with future expansions requiring additional permits. While there have been various maintenance and operational permits over the years for both commercial and residential portions of the building, including roof work, electrical upgrades, and window replacements, the property has also faced ongoing external challenges as evidenced by recent 311 calls regarding urban issues such as garbage overflow, street cleaning needs, and tree maintenance concerns in the vicinity of the building. The property has an established history of regular maintenance and improvements, particularly focusing on both commercial and residential upgrades.

The grocery store component has received particular attention in terms of equipment and infrastructure improvements, including the installation of new electrical systems, plumbing fixtures, and cooling equipment. The building's mixed-use nature has required careful coordination of various permits and compliance with commercial regulations, particularly regarding health and grocery use continuance. Recent concerns about sewer-related issues and exterior maintenance needs suggest ongoing upkeep requirements, while the commercial space has shown adaptability to maintain its grocery business status over the years through various permitted modifications and improvements. The building's permit history demonstrates a pattern of addressing both routine maintenance and significant upgrades, though some historical permits from the early 1990s show as cancelled or expired, indicating potential changes in planned improvements during that period.
