1339-1341 33rd Ave, San Francisco, CA 94122

The property at 1339-1341 33rd Avenue in the Central Sunset neighborhood is a two-story, four-unit multifamily residential building constructed in 1947 and currently owned by Lawrence Shu-nan Mao. The building has undergone several significant maintenance and improvement projects over the years, most recently including a reroofing project in 2022 costing $10,000.

Infrastructure upgrades have been made to improve building systems, including a sewer line replacement in 2007, installation of a 200-amp meter panel in 2013, and addressing dry rot issues in 2009 that affected the exterior walls at the building's landings. The building has a notable history of violations recorded in 2002 related to safety and security requirements, including the need for smoke detectors, security viewers, fire extinguishers, and maintenance of the garage area; however, all these violations were officially abated by July 2022.

Routine inspections by Housing Inspection Services have occurred in 1999, 2002, and most recently in 2022, with no active violations on record. Recent service calls from 2015 through 2023 have primarily concerned external issues such as street cleaning, tree maintenance, parking enforcement, and graffiti, with no calls directly related to building safety or maintenance concerns.
