Augrented Insights Report

This two-unit, two-story multi-family residential building, located at 4639-4641 18th Street in the Eureka Valley/Dolores Heights neighborhood, was constructed in 1908 and is currently owned by David Ryan Corbel 2008 Revo. The property has undergone several significant improvements over the past 14 years, with major renovations occurring in 2016 including a garage post removal and reinforcement project ($50,000), interior remodeling of the second floor ($50,000), and a comprehensive kitchen and powder room renovation ($38,000).

Additional substantial work was completed in 2010, including kitchen and bathroom remodels on the second and third floors, window replacements, and various electrical upgrades totaling approximately $75,000. The building has received extensive infrastructure upgrades, including electrical rewiring, plumbing improvements, and HVAC updates. Recent maintenance records show the installation of a new forced air heater and ducting in late 2017, along with plumbing work that included sewer line replacement and kitchen remodel updates.

The property has experienced recurring issues with parking enforcement, particularly in 2024, with multiple calls regarding driveway blockages. There is also an open 2020 case regarding a collapsed sidewalk that may require attention. Three recent 311 calls in late 2024 primarily concerned parking enforcement matters, while there was one resolved call about Christmas tree removal in January 2025.
