Typical requirements include owner-occupancy of the primary or accessory unit, minimum lot area (often larger than standard for the district), one additional off-street parking space, and compliance with setback and height rules for accessory structures. The ADU must have its own kitchen and bathroom but share an entrance or utilities depending on district. Building permits and certificate of occupancy required.
