Add Space, Add Value with an ADU
An accessory dwelling unit (ADU) is one of the smartest ways to make your property work harder for you—whether you're creating a comfortable place for aging parents, a private space for adult kids, or a rental that helps offset your mortgage. At Pacific Mountain Dwellings, we design, permit, and build ADUs across the Pacific Northwest with real foundations and lasting quality. From your first questions to the final walkthrough, we handle the details so you can focus on how you'll use the new space.
ADUs and DADUs
A DADU is a detached accessory dwelling unit: a separate small home that stands on its own in your yard, rather than space added onto or carved out of the main house. Many homeowners choose a DADU for the privacy it gives both households—a backyard cottage for a parent, a home office away from the kitchen, or a rental with its own front door. Whether you're picturing a detached unit or an ADU that works with your existing home, we'll talk through what your lot allows and handle the permits, the foundation and the build.
Why choose Pacific Mountain Dwellings
- We handle permitting from the start. ADUs come with their own set of local rules, setbacks, and approvals. We know how to navigate the process so your project moves forward without costly surprises or delays.
- Built on real foundations. Our ADUs are built to last, with proper foundations that add genuine, long-term value to your property—not temporary structures you'll outgrow.
- One team, start to finish. As your general contractor, we manage the entire build. You get a single point of contact instead of juggling multiple subcontractors and schedules.
- Straightforward, honest communication. We'll give you clear answers about what your project involves, what to expect, and where things stand at every stage.
Our ADUs process
- Talk it through. Call us at (360) 318-3984 to describe your property, your goals, and your budget. We'll help you understand what's possible on your lot.
- Design and plan. We work with you to shape a layout and finishes that fit how you'll actually live—whether that's a compact studio or a full one-bedroom with a kitchen and bath.
- Permit and approve. We prepare and submit the paperwork, coordinate with local officials, and secure the approvals your ADU needs.
- Build with care. Our crew pours the foundation and constructs your ADU with attention to quality and detail, keeping you updated as work progresses.
