750 Delta St, San Francisco, CA 94134

The two-unit residential building at 750 Delta Street in Visitacion Valley is a single-story flats and duplex structure built in 1943, currently owned by Carlos Rodriguez. The property has undergone several notable changes and faced multiple compliance issues over the past decade. Most significantly, from late 2013 through 2014, the building was subject to violation proceedings regarding an unauthorized roof structure in the rear yard, measuring approximately 16 feet by 10 feet.

These violations, which triggered monthly monitoring fees, were ultimately resolved through a $1,500 permit to remove the illegal structure completed in late 2014. During this same period, there was also an effort to legalize a 510-square-foot first-floor rear porch, though this permit status is listed as "filed." The building has seen some infrastructure improvements, including a gas houseline extension in 2010 and a significant electrical upgrade from 100A to 200A completed in 2022. More recently, there have been recurring sewer system issues, with multiple sewage backup incidents reported in 2024 (September) and a missing side sewer vent cover reported in January 2025.

The property has a history of sidewalk-related issues, with complaints and repairs documented in 2014 and 2018 regarding lifted and collapsed sidewalks. Two older permits from the 1980s indicate past repair work, including a September 1987 project to address visible damage under the front entryway and an August 1989 permit to conform to building code requirements, though both permits are now listed as expired. The building's recent service history suggests ongoing attention to maintenance and infrastructure, particularly regarding sewer systems and electrical capacity, while also indicating some persistent challenges with building infrastructure elements such as the sidewalk and sewer connections. The property's history shows significant regulatory engagement in 2013-2014 regarding unauthorized modifications, though these issues were ultimately resolved through proper permits and abatement actions.
