2977-2979 21st St, San Francisco, CA 94110

The property at 2977-2979 21st Street is a three-story mixed-use building constructed in 1885, containing three residential units and ground-floor commercial space. The building has undergone several significant renovations and infrastructure upgrades over the past two decades, including a comprehensive sewer line replacement in December 2013, which extended from the front of the building to the street trap.

Recent work in 2014 included the installation of new ductwork, furnace, and complete rewiring of the house, covering two bathrooms, kitchen, three bedrooms, living room, and various appliances. The building has experienced recurring water-related issues, particularly noticeable between 2021-2023, with multiple complaints regarding water intrusion affecting neighboring properties, inadequate drainage, and water entering building spaces. These water-related complaints appear to remain unresolved, with an active inspection case opened in January 2023 regarding problematic downspouts and standing water.

The property has undergone various interior improvements, including extensive remodels of bathrooms and kitchens in 2011-2013, though some older permits from 1999-2002 related to adding master bedroom/bath and final inspections show as expired. Recent maintenance records from 2022-2023 indicate regular attention to basic building systems, though water-related issues continue to be a prominent concern. The building's history includes typical urban property maintenance issues such as sewer backup incidents, parking concerns, and general upkeep matters, with the most recent significant maintenance work focusing on building systems and infrastructure rather than structural alterations.
