611 Pennsylvania Ave, San Francisco, CA 94107

The property at 611 Pennsylvania Avenue in Potrero Hill is a multi-family residential building constructed in 1941, currently owned by the Ferris David J Jr Living Trust. The building has undergone several significant maintenance and improvement projects over the past decades, including a reroofing project in 1994, installation of vinyl siding in 1990, and aluminum window installation in 1986, though both the roofing and window permits have since expired.

More recently, in 2008, there was a completed flue replacement project. Of particular concern is the building's history of sewage-related issues, with seven documented incidents of sewage backups between 2016 and 2017, all involving 4-inch vent problems and all eventually resolved. This pattern suggests recurring plumbing system challenges during that period.

The property has also experienced some infrastructure issues with three documented pavement defects, including incidents in 2013 and 2019, both of which were resolved. The most recent reported incident was in February 2022, involving construction equipment blocking a parking space, which was also resolved. While these records do not provide a comprehensive picture of the building's current condition, they indicate a historical pattern of plumbing system challenges and periodic infrastructure maintenance needs, particularly in the context of its age.
