21 Flood Ave, San Francisco, CA 94131

21 Flood Avenue is a two-family residential building constructed in 1908, owned by Ofelia Moran, that has undergone numerous significant and concerning changes over the years. Most notably, in October 2020, the property experienced a concerning series of events including a kitchen fire, electrical issues, and safety violations, revealing that the building had been illegally converted from its permitted two-family dwelling status into five separate units with five kitchens. This unauthorized conversion led to the issuance of multiple notices of violation (NOVs) in October 2020, with specific concerns about blocked egress stairs, unsecured roof access, and burned wiring.

The building's safety issues were further highlighted by a complaint in October 2020 regarding hazardous outlet wiring, exposed wiring, and deteriorated electrical equipment, with reports of tenants living in a red-tagged building and using extension cords from vehicles, though notably, these complaints emerged after the fire incident. In response to the regulatory findings, a permit was issued in January 2023 to remove two unauthorized basement units and one unauthorized first-floor unit, with an estimated cost of $4,000. Prior to these recent issues, the property had historical compliance matters, including a 2018 permit for various abatement work, notably the removal of unauthorized structures including sheds and fencing, which had been the subject of a 2008 violation.

The building underwent some permitted modifications in the late 1980s including stair relocation and bathroom construction. Recent 311 calls from late 2024 show ongoing concerns with garbage and debris management around the property, though these are not directly related to the building's structural or safety issues. The building's history reflects a pattern of unauthorized construction and occupancy modifications, culminating in the most recent efforts to return the property to its original two-unit configuration as required by city enforcement actions.
