ADU Garage Conversion Guidelines

Adding new Accessory Dwelling Units (ADUs) to existing buildings throughout San Francisco is possible and encouraged with adequate thought and sensitive planning into each project. There are common designs for adding an ADU to existing residential buildings, which often introduce new features to the street-level-facing facades. The Department’s recommended design guidelines are intended to provide common methods to altering street-facing elevations to incorporate ADUs or required access ways, and should guide your project at the outset.
