4226 20th St, San Francisco, CA 94114

The property at 4226 20th St is a 3-story, 2-unit multi-family residential building constructed in 1892, currently owned by Elena Shulman. The building has a significant history of unauthorized unit modifications, with multiple attempts to legalize additional units between 1989-2005. Notably, in 2005, the building was cited for containing two unauthorized basement units (designated Units B and C) - one at the back with a complete kitchen and bathroom, and a second at the front with inadequate light and ventilation.

These violations initiated a series of enforcement actions including multiple Notices of Violation (N.O.V.) in 2005, though efforts to legalize the units through permits in 2005 and 1990 were ultimately disapproved or cancelled. The property also faced serious maintenance issues, including a raw sewage backup incident in 2001 that displaced a tenant and damaged property. More recent history shows ongoing concerns with the property, particularly regarding tree roots affecting the sidewalk (reported multiple times in 2022-2023) and various sidewalk cleanliness issues.

The building has undergone several permitted improvements over the years, including window replacements in 2005 and circuit modifications in 2003, though some repairs and improvements appear to have been done without proper permits, as evidenced by historical complaints. The most recent building-related activity on record was limited to two street space permits issued in 2019. The property remains subject to historical violations regarding the unauthorized units, with the Planning Department records showing attempts to address these through various applications, though without successful resolution.
