ADU stands for Accessory Dwelling Unit—a secondary residential unit built on the same lot as a primary residence.
It’s a self-contained living space that includes a kitchen, bathroom, and sleeping area. ADUs can be attached, detached, or built within existing space like a garage or basement.
A JADU is a smaller version of an ADU—typically under 500 sq. ft.—and is created within the footprint of an existing home, such as a converted bedroom with a small kitchenette.
Start by contacting a licensed ADU builder like us. We’ll help with design, permits, and construction. Every city has zoning laws, so we ensure full compliance with local requirements.
Many states allow ADUs, including Arizona, California, Oregon, Washington, and others. Local regulations vary, so it’s important to check with your city planning office—or ask us!
In many cases, yes! It depends on your lot size, zoning, and setback rules. Our team can evaluate your property and guide you through the process.
