3917-3919 Noriega St, San Francisco, CA 94122

The property at 3917-3919 Noriega St is a two-unit, two-story multi-family residential building with a commercial ground floor, constructed in 1950 and currently owned by the Cheng Family Trust. The building's history reveals significant concerns about habitability and safety, particularly between 2015-2016, when multiple complaints were filed regarding illegal unit conversion, rodent infestations, inadequate insulation, plumbing issues, and noise disturbances from the ground-floor restaurant affecting second-floor tenants.

A particularly concerning pattern emerged in early 2025, with ten consecutive reports of garbage overflow issues requiring Recology intervention, though these relate to street cleaning rather than building conditions. The property has undergone several documented modifications, including a 2007 restaurant conversion with associated plumbing and electrical upgrades (completed), installation of a cooking hood fire suppression system (2007), and various improvements dating back to the 1980s including window replacement and awning installation.

A fire safety violation was issued in April 2018 regarding the storage of combustible materials, though this has since been abated. While several building and plumbing permits from 2016-2023 were either withdrawn or expired, the property shows some maintenance history such as a gas line replacement in March 2023. The most recent complaints suggest ongoing operational challenges, though these are primarily related to street-level maintenance rather than building conditions.
