3271 20th St, San Francisco, CA 94110

The property at 3271 20th Street is a two-unit multi-family residential building located in San Francisco's Inner Mission neighborhood. Built in 1904 and classified as a Flats & Duplex building, it has undergone several significant renovations and improvements in recent years under the ownership of the Owens Dannels Trust.

The most substantial work was a voluntary foundation replacement project in 2020 costing $50,000, which included both structural and seismic upgrades. Other completed improvements from 2019-2021 included electrical system upgrades (new subpanel, outlets, and lighting), plumbing installations (laundry room facilities and garage area drain), and various exterior improvements such as siding restoration and window replacements. Recent building maintenance and resident quality of life issues have emerged primarily through 311 calls, with the most pressing concerns being parking violations (sidewalk parking and driveway blocking) and environmental maintenance (overgrown tree and garbage).

As of late 2024, there are ongoing issues with a tree maintenance request and an encampment. The building's most recent permitted work, completed in January 2023, involved scope reductions from original plans, removing several proposed improvements including new siding, entry doors, and staircase modifications. While the building has experienced some maintenance challenges, the property has seen substantial infrastructure improvements in recent years, particularly in terms of structural integrity and basic systems modernization.
