777-781 Union St, San Francisco, CA 94133

The property at 777-781 Union Street in North Beach is a 2-unit, 2-story multi-family residential building with ground-floor retail, constructed in 1907 and currently owned by the Quan Linda D Family Living trust. The building has undergone several significant modifications and faced multiple regulatory challenges over the years. Most notably, between 2010 and 2012, there were two complaints filed regarding an unauthorized roof deck construction, which led to a formal enforcement action (complaints #201077526 and #201077528) and subsequent legalization process costing $6,000.

A related complaint about an improperly installed metal structure was filed in 2011 but was abated within weeks. The building's infrastructure has required attention in recent years, with two sewer-related issues reported in late 2019, though inspections showed no significant problems with the system. More recently, there has been a tree-related concern noted in July 2023 regarding lifted sidewalk tree roots, which remains open as of October 2023.

The property's external environment has experienced various typical urban challenges, including two documented cases of driveway blocking (in 2024 and 2021), and municipal services have intervened for tree maintenance and bicycle sharing operations in the vicinity. Historical permit records show several applications and renewals between 1998 and 1999 related to garage access modifications. The building's most recent activity consists of standard parking enforcement and urban maintenance issues rather than any substantial structural or regulatory concerns.
