Different Types of ADUs Seattle

Emerald ADU Builders Seattle is a company that is committed to providing the best ADU Seattle. There are different types of accessory dwelling units we can offer, including:


Detached ADUs (DADU)

Just as the name implies, these are ADUS which are not attached to the main house in any way. However, they will be within the property area and some homeowners choose to build small replicas of the main house. These are commonly referred to as backyard cottages. Our contractors will be ready to help with the design and construction as well as the acquisition of the relevant permits.


Attached ADUs

These are similar to the detached ADUS but they are connected to the main house on the property such as a garage ADU. As a matter of fact, there are some utilities which may be shared and even some walls. However, there will be a different entry area from the main house.


Repurposed Existing Space

This is where garage conversions come in and other parts of the property that may be converted to accommodate your needs. Existing space is taken and this will be converted into an independent unit.


Whatever type of Seattle ADU you may be interested in, our contractors are ready to work with you and ensure that your needs are met in the best way possible. Contact us today for more information and to get started with your construction project.
