1479 48th Ave, San Francisco, CA 94122

The property at 1479 48th Avenue in San Francisco's Outer Sunset neighborhood is a two-story, four-unit multifamily residential building constructed in 1956 and currently owned by Hum Ann L. The building has undergone several significant updates over the past decade, including a gas furnace replacement in 2022 and water heater installation in 2012, with a notable electrical service upgrade to 200 amps completed in 2013. However, the building's history reveals several concerning safety issues, particularly regarding heating equipment.

In 1998, there was a serious carbon monoxide leak situation reported, and in 2013, there were complaints about a problematic heater that allegedly caused linoleum damage and had not been properly checked, following earlier work that raised fire department concerns. The building has been subject to multiple routine inspections and has faced various fire safety issues over the years, particularly in the early 2000s. These included problems with fire extinguisher maintenance, smoke detector requirements, and combustible storage concerns, all of which were subsequently resolved.

The property had a documented rodent issue in 2010, and in 1996, there was a complaint about locked windows potentially impacting emergency egress. While there have been no reported civilian injuries from the building's fire incidents according to available records, there is a pattern of heating and safety-related concerns that has persisted over time. Recent maintenance has included proper resolution of fire safety violations, as evidenced by the completion status of various permits and inspections, although a general request for environmental health services was noted in December 2023. The building is now mostly maintaining compliance with safety regulations, with recent repairs and upgrades appearing to be properly documented and completed.
