Your Home. Your Future. Your ADU. 

Accessory Dwelling Units, also called ADUs, are small, self-contained homes on the same lot as your main house. Whether you’re planning for aging parents, adult kids, rental income, or future flexibility, an ADU can help you meet life’s changing needs. 

Kirkland offers pre-approved ADU plans to save you time and money. Building an ADU is easier than ever. And we’re here to help.
