Sometimes known as accessory apartments and in-law suites, among other names, Accessory Dwelling Units (ADUs) provide more housing options in existing neighborhoods by allowing homeowners to build an additional unit on their lots.

ADU is a catch-all term for independent living units — whether they are attached to an existing home or placed elsewhere on the property, such as over a detached garage or as a stand-alone structure in the backyard. ADUs are among the housing solutions that can help to ensure that people of all ages, including older adults, have a roof over their heads.

AARP partnered with Blink!LAB Architecture to create Accessory Dwelling Units: A Step-by-Step Guide to Design and Development This resource guides homeowners through the steps of designing and building an  ADU on their own properties. It includes information on zoning and other regulations, project financing and budgeting, design considerations for planning the space and 3 ADU floor plans to accommodate different household needs.
