Augrented Insights Report

The two-unit residential building at 509 Corbett Avenue in Twin Peaks, owned by the John & Germana Congi Family, was constructed in 1981 and is classified as a Flats & Duplex structure spanning two stories. The building's documented maintenance history includes two roofing projects: one from 1993 (issued) and another from 1997 (expired), though the current roof status is not documented in the provided data.

The property has experienced several maintenance and environmental issues in recent months, with the most significant being a sewer odor incident in October 2024 that required attention to the upper lateral system, though this was resolved. Other recent maintenance concerns include ongoing loose garbage reported in August 2023 (still open as of the latest data), and multiple instances of graffiti (February 2024 and July 2024) with one case showing no graffiti upon inspection.

The area around the building has seen various municipal service interventions, including a Christmas tree removal in January 2024, parking enforcement in August 2024, and multiple sign repairs in July 2023 related to missing support for speed limit signs. Planning records indicate activity at neighboring addresses 511 and 515 Corbett Avenue, with approved variance and CEQA clearance for proposed multi-unit developments, though these are not directly related to 509 Corbett Avenue.
