1846-1848 48th Ave, San Francisco, CA 94122

This two-unit residential building, located at 1846-1848 48th Avenue in San Francisco's Outer Sunset neighborhood, is a two-story flats and duplex structure built in 1946 and currently owned by the Mabel Y Lee 1999 Living Trust. The property's maintenance history shows attention to critical infrastructure, particularly regarding roof maintenance, with two documented roofing projects: one completed in 1991 and another in 2004, the latter costing $3,500.

Additionally, safety improvements were made in 1990 when repairs were undertaken to the rear stairs, including the replacement of steps and handrails, addressing important structural safety concerns. The building's external environment has experienced minimal issues over the past several years, with only two documented 311 calls in the vicinity. In March 2016, there was a report of loose garbage requiring street and sidewalk cleaning, which was resolved by the Department of Public Works.

More recently, in November 2018, there was a report of an abandoned vehicle, which was addressed by the Department of Public Transportation but the vehicle was gone upon arrival. These external incidents do not appear to have had any direct impact on the building's condition or habitability. The historical records indicate regular maintenance of critical systems, particularly focusing on roofing and structural safety during the past three decades.
