What is a DADU, and how is it different from an ADU?

A DADU, also known as a Detached Accessory Dwelling Unit, is a free-standing house or cottage that exists on the same lot as another single-family home – typically the primary residence. It is an isolated, fully functional living space consisting of, at minimum, a bedroom (open or closed), kitchen, and bathroom.

An attached dwelling unit (ADU) or mother-in law apartment, unlike an DADU, will exist inside your house, typically in your basement. An ADU will be less expensive to create because it is built within the existing structure of your home.

Benefits of DADUs

There are a number of unique benefits of building a DADU, including:


Additional Space

DADUs offer additional usable space you can use for anything from a home office or gym to a guest suite or rental unit. If you wish your home had more indoor space and would like that space to be flexible, this could be a fantastic path to take.

Rental Income Opportunity

A DADU is a great option if you want to capitalize on the Seattle tourism industry and tap into a new income stream via platforms like Airbnb and VRBO. You can host renters and make money while still isolating and maintaining the privacy and security of your own home.

Flexible Living Arrangements

A DADU allows for multigenerational living, enabling extended family members to live together while maintaining privacy and independence. A DADU is flexible, you can host guests or family for an extended period while maintaining your privacy - plus they get treated to their own fully functional living space!

Increased Home Value

DADUs are becoming increasingly valuable to potential buyers in the Seattle area. Adding square footage of home space on your property while creating the multitude of options and income generation that a DADU creates, will increase your property value significantly.
