509 Lincoln Way, San Francisco, CA 94122

The two-unit residential building at 509 Lincoln Way, located in San Francisco's Inner Sunset neighborhood, is a two-story flats and duplex structure built in 1909, currently owned by Ellen Sueda and Mark Leach. The property has undergone several significant changes and faced multiple maintenance challenges over the past several years. Most recently, in June 2024, a building permit was issued for interior modifications including the removal of a non-load bearing wall to reconfigure the dining room and bedroom spaces.

The building has seen two major roofing projects in its history, with work completed in 1990 and 2007, suggesting regular maintenance of major systems. The property has experienced drainage and water-related issues, particularly in 2021, when complaints were filed regarding water intrusion problems affecting both 509 Lincoln Way and the neighboring property at 519 Lincoln Way. These concerns involved drainage issues affecting foundations and concrete structures.

More recently, in December 2023, there was a flooding incident requiring attention from PUC Sewer Operations on the property. The building's exterior maintenance history shows attention to urban challenges, with multiple instances of graffiti removal and maintenance work documented between 2020 and 2022, though these were primarily related to public infrastructure rather than the building itself. Other exterior issues reported through 311 calls included concerns about overgrown trees (July 2022) and a street light electrical safety issue (July 2021), both of which were resolved through appropriate city services.
