671 45th Ave, San Francisco, CA 94121

The property at 671 45th Avenue in San Francisco's Outer Richmond neighborhood is a one-story multi-family residential building classified as a Flats & Duplex, containing two units and currently owned by Denis Bouvier 2011 Revoc Fm. The building's legal status as a two-unit residence was officially documented in 2013, following a permit verification process that confirmed previous conversion work completed in 1953. Between 2010-2011, the property underwent significant renovations including kitchen and bathroom remodels on both floors, installation of additional bathrooms, and replacement of front door and window fixtures, with proper permits obtained for electrical upgrades including the installation of a double meter system.

However, there is an active complaint filed in February 2020 regarding an allegedly unauthorized in-law unit (Unit A) in the garage area, reportedly containing illegal and hazardous kitchen facilities with gas range, electrical work, and plumbing installations without proper permits. This complaint remains active as of November 2019 observations. The property has a history of regulatory scrutiny for rental activities, including a documented case of illegal short-term rental activity via Airbnb in 2017, though that violation was subsequently closed and appeared to have ceased.

The building's maintenance history shows attention to basic upkeep, with a documented reroofing project completed in 2001, though that permit has since expired. A noise complaint regarding excessive noise was filed in September 2016 and subsequently closed, categorized as informational. The property has undergone several legitimate improvements and modernization efforts over the past decade, as evidenced by the various completed permits, though the active complaint regarding potentially unauthorized modifications raises questions about full compliance with building regulations.
