An ADU isn’t just a tiny house in the backyard.
It’s a flexible second home on your property you fully control.
An ADU (Accessory Dwelling Unit) is a small, independent home built on the same lot as the existing single-family house. ADUs are also known as:
• Granny flats
• Casitas
• Backyard homes
• In-law suites
They offer a flexible way to increase your living space, boost property value, or generate rental income.
