Augrented Insights Report

The two-unit residential building at 3959 18th Street in the Eureka Valley/Dolores Heights neighborhood is a two-story flats and duplex structure built in 1900, currently owned by Mary Infanto. The property has experienced several significant maintenance issues over the past five years, most notably in 2019 when multiple building violations were documented regarding exterior maintenance, including peeling paint, window glazing seal repairs, weatherproofing issues on the siding, and lead hazard concerns.

These violations were all addressed and officially abated by August 30, 2021. The building's exterior maintenance history shows a pattern of neglect, with a 2017 complaint documenting unpainted surfaces for over 15 years, resulting in fading, peeling, and deteriorating wood components. More recently, the property has encountered a sewer issue in December 2023 involving a 4-inch vent line backup, which was resolved by PUC Sewer Operations.

The surrounding area has experienced recurring graffiti issues, with multiple reports between 2023 and 2024, though most were closed due to technical issues with reporting systems. Historical records show the building underwent reroofing work in 1988, and street space permits were issued in late 2019 (December and January 2020) for scaffolding-related activities, suggesting exterior work was being undertaken at that time. The building's documented history indicates periodic maintenance challenges, particularly regarding exterior preservation, though the owner has generally responded to violations when formally issued.
