669-671 Pennsylvania Ave, San Francisco, CA 94107

The 669-671 Pennsylvania Avenue property in Potrero Hill is a three-story, two-unit multi-family residential building owned by the Shelan 2011 Family Trust and constructed in 1908. The building has undergone several significant maintenance and safety-related improvements over the years, most notably a sewer lateral replacement completed in 2020 and a structural retrofit of existing gravity framing in 2016.

A notable building violation in 2008 resulted from unauthorized construction of new stairs and concrete piers, which was subsequently addressed through a $16,500 permit to properly remove and replace rear and side stairs. This incident also triggered a fire safety complaint regarding blocked exits, though these conditions were corrected promptly in both cases. The property has experienced multiple maintenance issues between 2020 and 2022, including several reports of damaged trees (with multiple complaints registered in September 2021) and one instance of graffiti in April 2022, all of which were resolved.

The most recent incident was a parking enforcement issue in January 2024. While the building's major structural and safety improvements have been properly documented and addressed through appropriate permits, the property has experienced occasional maintenance challenges typical of its age and type, particularly regarding exterior elements like stairs and trees. The building's permit and violation history suggests that when issues have arisen, they have generally been addressed through proper channels, though there was an initial period of unauthorized work in 2008 that required remediation.
