1-5 Nantucket Ave, San Francisco, CA 94112

The two-unit residential building at 1-5 Nantucket Avenue in Mission Terrace, owned by the Marta Lopez 2009 Revocable Trust, is a two-story flats and duplex structure built in 1961. Historical records show minimal major improvements, including a roof replacement in 1998 (permit expired) and window installations in 1991 (completed).

The property has experienced several infrastructure and maintenance issues in recent years, as evidenced by multiple service requests between 2024 and 2025. Most notably, there is an open sidewalk defect from December 2024 caused by tree roots, and an exposed power pole wire reported in June 2024 that remains unresolved. The building's surroundings have been affected by recurring issues with garbage and debris, with several cleaning calls recorded in early 2024.

Multiple complaints about driveway blocking in mid-2024 were addressed by parking enforcement, and there was a water-related issue involving a fire hydrant in July 2024 that has since been resolved. A false fire alarm incident was recorded with no civilian injuries. While these service calls indicate ongoing maintenance and access challenges in the immediate vicinity, they primarily relate to exterior and public infrastructure rather than the building's internal systems or structure.
