Whether you're exploring the idea for the first time or ready to move forward with a project, understanding how a DADU works is the first step toward making a confident decision.
Build a Detached Accessory Dwelling Unit on Your Seattle Property
A Detached Accessory Dwelling Unit is a standalone residential structure built separately from the primary home on the same lot. Unlike an attached addition or a converted basement, a DADU functions as its own independent living space, with its own entrance and layout.
- Guest accommodations for visiting family or friends
- Private living space for adult children or aging parents
- Multi-generational housing that keeps family close while maintaining privacy
- Home offices separate from the main living area
- Additional flexibility as household needs change over time
- Rental opportunities, depending on local regulations and individual circumstances
Every property is different, and the right approach depends on lot size, zoning considerations, and what you're hoping to accomplish. As a residential construction company based in Seattle, WA, MT² Construction helps homeowners think through these details before construction ever begins.
Benefits of Adding a Detached ADU to Your Property
Homeowners across Seattle explore DADU construction for practical, everyday reasons. Depending on your circumstances, a detached accessory dwelling unit may:
- Create additional living space without the need to relocate
- Offer flexibility as family needs shift over the years
- Make better use of underutilized backyard or side-yard space
- Provide separate accommodations for family members or guests
- Add long-term functionality to your property
Every homeowner's situation is different, and outcomes can vary depending on property specifics, local requirements, and individual goals.

Building a detached living space involves more than just construction—it requires thoughtful planning that reflects how you'll actually use the space.
Custom DADU Design and Construction
MT² Construction works with homeowners to shape a detached living space around their property layout, lifestyle needs, and design preferences.

Design and Preparation
Once goals are established, planning shifts to layout decisions, material choices, and the preparation work needed before construction begins.
Construction Phase
During construction, the team focuses on building the structure, coordinating the various stages of work, and maintaining clear communication with you throughout the project.
