639 Silliman St, San Francisco, CA 94134

The two-story multi-family residential building at 639 Silliman Street in the Portola neighborhood, owned by Paul & Ann Treanor, is a flats and duplex structure built in 1923. The building has undergone limited documented improvements, with the most significant being a $10,000 renovation in 2002 which included kitchen cabinet replacement, countertop installation, trim work, painting, and hardwood floor refinishing on the second floor, though this permit has since expired.

A notable incident occurred in February 2009 when multiple housing code violations were documented regarding interior surfaces, specifically involving mold and mildew problems on walls and ceilings, as well as the need for painting. These violations were officially abated by March 13, 2009.

More recent activity around the property has primarily involved external maintenance and municipal issues, with the most recent documented case being a mailing request to the Rent Board in October 2023 regarding fee housing inventory. The property has seen several infrastructure-related complaints in 2024, including issues with a damaged side sewer vent cover (July 2024), a water service request for a hydrant replacement (July 2024), and notifications about sidewalk defects (July 2023). The majority of recent complaints (2023-2024) have been related to parking and traffic enforcement matters, including multiple reports of illegal parking, sidewalk parking, and driveway blocking incidents, which have all been resolved through various enforcement actions or inspections.
