640-642 Missouri St, San Francisco, CA 94107

The property at 640-642 Missouri Street is a two-unit, two-story multi-family residential building located in Potrero Hill, built in 1987 and currently owned by Kenny A & Susie S C Pon Rev. The most significant recent building improvement was made in 2012, when vinyl siding was installed on the right side of the house and lightwell at a cost of $20,584, though this was non-structural and not visible from the street.

The building's permit history shows activity primarily from 1985 and 2012, with no major renovations or structural changes recorded in recent years. Between July and October 2024, there has been a notable cluster of municipal service calls related to the property and its immediate vicinity, with the most pressing issues including an open sidewalk defect caused by tree roots (reported September 2024), various parking enforcement matters, and multiple Rent Board inquiries. While the majority of these calls have been resolved or closed, there is currently one open noise complaint from July 2024.

Other reported issues, such as street lighting (resolved August 2024), garbage cleanup (resolved August 2024), and two abandoned vehicle complaints (July 2024), were appropriately addressed by respective city services. Additionally, there was one fire alarm incident on record related to a system malfunction, with no injuries reported. The property appears to be generally well-maintained in terms of structural integrity, though the recent spike in municipal service calls may indicate an evolving neighborhood environment requiring ongoing attention to urban infrastructure and services.
