An ADU (Accessory Dwelling Unit) is a small residential unit built on the same property as your main house. It’s basically a more official name for a guest house, but it comes with all the essentials: a kitchen, bathroom, living area, and its private entrance.

ADUs are a great way to add extra living space for one or two people. They can be perfect for family members, long-term guests, or even as a rental unit.

There are a few different types of ADUs, but most fall into three main categories:

Design Examples

Types of ADUs

  • Attached ADU

    This type is connected to your main home, usually built onto the side or back. It shares one wall but has its separate entrance and doesn’t connect to your home inside. Attached ADUs also have their kitchen, utilities, and living space.

  • Detached ADU

    Also known as a guest house, granny flat, or tiny home, this type is completely separate from your main house. It sits somewhere in your yard and offers maximum privacy and flexibility.

  • Internal ADU

    An internal ADU is created by converting part of your existing home, like a garage, attic, or basement, into an independent living space. It’s a smart and cost-effective way to add value and functionality to your home.

Why Are ADUs So Popular Right Now?

If you live in Los Angeles, you already know, finding affordable housing is tough. Limited space, high demand, and soaring prices have made the city one of the most expensive places to live in the country.

That’s why ADUs (Accessory Dwelling Units) have become such a popular solution.

They offer extra living space for family, guests, or renters—without needing to buy more land. Whether it’s a garage conversion, backyard unit, or addition, an ADU gives you a fully independent living space right on your own property.
