1337-1339 8th Ave, San Francisco, CA 94122

The property at 1337-1339 8th Avenue is a three-unit, two-story multi-family residential building located in San Francisco's Inner Sunset neighborhood. Built in 1912 and currently owned by Sarah A. Maloney, this flats and duplex-style building has experienced several significant maintenance and safety issues over its recent history.

Most notably, in 2010, the building underwent a routine housing inspection that revealed multiple fire and building code violations, including the need for handrails, roof deck repairs, fire extinguisher installation, and the removal of combustible storage or installation of automatic fire sprinklers. These violations were all resolved by May 2010. The building has also maintained its infrastructure through various improvements, including a sewer line repair in 2015 and water heater installation in 2009, though an earlier reroofing permit from 1996 shows as expired.

More recent concerns have emerged regarding the building's sewer infrastructure, with four documented sewage backup incidents between January and July 2025, involving discharge from various locations including side sewer vents, catch basins, and other locations. The property has generated multiple parking enforcement calls between 2021 and 2022, primarily related to vehicles blocking driveways and parking on the sidewalk, with several citations being issued. A single fire-related complaint regarding blocked exits was reported in August 2015 but appears to have been resolved within two weeks. The building's maintenance history shows regular attention to infrastructure issues, though the recent pattern of sewage-related incidents suggests ongoing plumbing system challenges that have persisted into 2025.
