Accessory Dwelling Units

Planning

Accessory Dwelling Units (ADU)

An ADU is a self-contained dwelling that may be located within a single-family dwelling or in a permanent accessory structure. Single-family dwellings with an ADU shall not substantially alter the structure or appearance of the existing structure. Accessory Structures that house an ADU shall be architecturally compatible with the primary structure. ADUs are often called mother-in-law, basement, or accessory apartments, cottage homes, accessory suites, or ancillary units.
