454-456 3rd Ave, San Francisco, CA 94118

The property at 454-456 3rd Avenue in the Inner Richmond is a two-unit, two-story multi-family residential building constructed in 1908, currently owned by Paul Tam. The building underwent significant renovations between late 2002 and 2004, including electrical upgrades (with permits showing installation of 10 circuits, 150 amps system, and additional circuits and fixtures), bathroom remodels on both floors (including the installation of new showers and bathroom fixtures), and various structural modifications such as stairwell details and wall relocations.

A notable incident occurred in February 2002 when an illegal dwelling unit was discovered behind the garage, containing unapproved wiring, plumbing, and unauthorized living facilities, though this violation was officially abated by June 2002. The building has generally been well-maintained since these initial renovations, with the most recent major work being a sewer repair completed in 2012.

The property has had several electrical and plumbing improvements, as well as multiple permits for interior modifications during the 2002-2004 renovation period. Recent activity at the address has been primarily related to parking enforcement and graffiti issues on nearby infrastructure, with no building-specific complaints or violations recorded in recent years. The last three 311 calls were regarding abandoned vehicles in November 2023, though these were external to the building itself and were handled by city traffic control authorities due to the APEC event.
