Types of Accessory Dwelling Units (ADUs)

Single-family ADUs are secondary housing units that are located on the same lot as a single-family home. These units are also sometimes referred to as granny flats, in-law suites or backyard cottages.

Some popular ADU types:

Junior ADU (JADU)
These are smaller units that are typically less than 500 square feet and are often created by converting a single room within the primary residence.
Attached ADU
These are units that are attached to the main house, often as an addition or a converted garage.
Detached ADU
These are stand-alone structures that are separate from the primary residence. They can be built on the same lot as the main house or on a separate lot.
Basement ADU
These are units that are located in the basement of the primary residence.
Garage ADU
These are units that are built above or within an existing garage.
Multi-family ADU
Sometimes referred to as a secondary suite, these ADUs are designed to be part of a larger multi-family residential building, such as an apartment complex or duplex.
