4427-4431 Mission St, San Francisco, CA 94112

The three-unit, two-story multi-family residential building at 4427-4431 Mission Street in the Excelsior neighborhood, owned by 4427 Mission LLC, has a documented history dating back to its 1950 construction. The property has undergone several significant maintenance and improvement projects, including two reroofing jobs (1996 and 2012), plumbing updates (lavatory replacement in 2015 and underground gas piping in 2013), and electrical work (new circuit and lighting installation in 2003).

A notable building complaint was filed in 2012 regarding unpermitted store remodeling and rental activity, though this issue was quickly addressed within five days. The property has experienced recent challenges related to noise and graffiti.

From late 2023 through 2025, there have been multiple complaints about noise from entertainment venues, including several open cases in early 2025, with one case being resolved through inspector education regarding permitting requirements. The building has also faced periodic graffiti issues throughout 2023-2024, with offensive graffiti cases being reported and subsequently resolved. Planning records indicate the property is permitted for bar use, with approvals for Type 42 and Type 48 licenses, including the existing "Rocks Den" bar operation at 4431 Mission Street, which is subject to specific planning code conditions.
