Definition of ADU

Before delving into the specifics of accessory dwelling units (ADUs), it’s essential to grasp their fundamental definition. An ADU, also known as a granny flat, in-law unit, or secondary suite, refers to a self-contained living unit located on the same grounds as a single-family home. This additional unit is equipped with its own entrance, kitchen, bathroom, and living space, providing occupants with complete autonomy and privacy.

ADUs come in various forms, including converted garages, basement apartments, detached cottages, and above-garage units. They are designed to accommodate diverse living arrangements, such as housing elderly parents, providing rental income, offering a separate living space for adult children, or simply expanding the overall living area of the property.
