The two-unit residential building at 1387-1389 45th Avenue in the Outer Sunset, owned by Cheung Ai Hua, is a two-story flats and duplex structure built in 1958. The property has a significant history of permit violations and unauthorized modifications, with multiple enforcement actions between 2000 and 2011. Major issues from 2002-2008 included the construction of illegal living spaces and extensions, including an unauthorized kitchen on the ground floor and deck extensions on the 2nd and 3rd floors, leading to several Notices of Violation and the necessity of multiple permits to remove illegal structures.

The building underwent some legitimate improvements, including a ground floor family room, bedroom, and bathroom addition in 2000 (with permit #200006152726). More recent building infrastructure work includes a house trap and sewer line replacement in 2010 and completion of various plumbing and electrical work to remove unauthorized installations. The property has maintained compliance with resolved violations since 2011, with no active building code issues on record.

Recent activity surrounding the property has primarily involved standard urban maintenance issues captured in 311 calls, including parking enforcement requests and general street cleaning matters. These calls for service, ranging from 2020-2024, have generally been related to parking violations, such as sidewalk parking and driveway blocking, as well as routine sanitation issues like garbage overflow and illegal postings. The most recent building-related permit activity was recorded in 2010, suggesting no significant structural modifications or unauthorized improvements have occurred in the past 13 years, indicating improved compliance with building codes and regulations.
