1557-1559 Noe St, San Francisco, CA 94131

The property at 1557-1559 Noe Street is a two-unit, two-story multi-family residential building located in San Francisco's Noe Valley neighborhood. Built in 1969 and currently owned by the Wanda M Low Revocable Trust, this flats/duplex building has undergone several significant improvements in recent years, most notably the installation of a comprehensive fire safety system. In 2021-2022, a new NFPA 13R fire sprinkler system was installed in the lower floor and garage, followed by a sprinkler monitoring system in early 2022, demonstrating the owner's commitment to safety upgrades.

The building underwent substantial work in 2019 to legalize an additional ground floor unit, including structural improvements to meet 2016 SFBC requirements, and previously received an electrical service upgrade from 100 to 200 amps in 2011. The property has experienced recurring plumbing issues, with three documented sewage backup incidents through the 4-inch vent system between 2018 and 2024, including the most recent incident in February 2024. External maintenance concerns have included tree root damage to sidewalks reported in 2023 and 2022, and there have been two instances of graffiti (2019 and 2020) that were resolved.

The building's infrastructure maintenance history includes reroofing work performed in 2017 (cost: $7,800) and 1991, though the earlier permit has expired. A non-emergency carbon monoxide detector activation was recorded, with no CO detected and no injuries reported. The property has generally maintained active responses to both routine and emergency maintenance needs, with most recent 311 calls being promptly addressed.
