Accessory Dwelling Units, or ADUs, are secondary housing units either attached to or detached from the main home on a single-family lot. ADUs come in all shapes and sizes, and they offer flexibility for families as financial and living needs change.
To learn more about ADUs, including types, benefits, and resources, visit our ADU Overview page.
The ADU Showcase highlights ADUs designed by AIA Seattle member architects. Each ADU is uniquely designed based on local regulations, site conditions, family needs, and client preferences.
AIA Seattle’s ADU Tour moved to an online format in 2020 – the ADU Showcase. We are accepting applications for attached or detached ADUs to showcase on our website. You can find more info here and access the form to submit your project.
