720 Potrero Ave, San Francisco, CA 94110

The two-unit, two-story residential building at 720 Potrero Ave in the Inner Mission neighborhood, currently owned by the Tam/leung Family Trust, has a documented history of significant code compliance issues dating back to the year 2000. The most substantial ongoing concern appears to be related to an unpermitted two-story rear addition measuring approximately 12' x 12', which generated multiple violation notices between January and April 2000, with a director's hearing scheduled for June 2000.

This unauthorized construction was subsequently addressed through a permit application in May 2000, which has since expired. Additional building complaints from 1999-2000 referenced an illegal ground floor rear unit and unauthorized renovations, though some of these complaints are no longer active. More recently, the building has been the subject of a January 2023 complaint regarding blight and peeling lead paint, and there is an active complaint from March 2000 regarding remodeling without proper permits.

The surrounding area has experienced various municipal service issues in 2024-2025, including multiple reports of streetlight problems, a fallen tree, and debris on public property. Several 311 calls in late 2024 documented infrastructure and public space maintenance needs, including a damaged traffic signal, though these are not directly related to the building itself. The property's documented history suggests persistent challenges with code compliance and unauthorized modifications, though the most recent building-specific complaint concerning lead paint was filed over seven years ago.
