Best ADU Builder in Portland, Oregon

Best Adu Builder In Portland, Oregon

As Portland continues to embrace accessory dwelling units (ADUs) as a smart housing solution, choosing the right ADU builder has never been more important. From navigating complex local regulations to delivering high quality design and construction, the best ADU builder in Portland, Oregon is one who understands the city, the process, and the unique needs of homeowners.

Why ADUs Are Popular In Portland

Portland is one of the most ADU-friendly cities in the country. Flexible zoning rules (like the recent RIP2 standard allowing Portland homeowners to have one ADU in the basement and one ADU out back and a Tiny House on Wheels parked in the yard), reduced system development charges (SDCs), and strong demand for rental housing have made ADUs an attractive option for homeowners. Whether you’re building a backyard cottage for rental income, housing family members, or aging in place; not only can an ADU increase your property value, but it can also add flexibility to your property. However, Portland’s permitting process, utility requirements, and site conditions can be challenging. That why it’s essential to hire Portland ADU for your next project.

A Local, Client Focused Approach

What truly distinguishes a great ADU builder is a commitment to the homeowner experience. Clear communication, responsiveness, and a collaborative approach make the process far less stressful. At Portland ADU, our builders take time to understand your goals, whether that’s rental income, multi generational living, or future flexibility, and tailor the project accordingly.

But don’t just take our word for it. With many satisfied customers, we let the results speak for themselves. With one customer describing the process as, “Jason was responsive, very knowledgeable and patient with us as we worked through the details of the job… His crew worked efficiently, professionally and was extremely sensitive to working safely and limiting the disturbance during construction.” For us, projects like this highlight why a local, client focused approach matters. Every site, every homeowner, and every ADU comes with unique needs that deserve careful attention.
