Additions & ADU Construction
Your home should grow as your needs change. Whether it’s welcoming a new family member, creating a dedicated home office, or generating rental income, a well-designed addition or accessory dwelling unit (ADU) can add both comfort and long-term value.
At Tieton Construction, we’ve spent more than 25 years helping Portland Metro homeowners make the most of their property. Our additions are designed to blend seamlessly with your existing home, while our ADUs provide flexible, independent living spaces that fit today’s lifestyle.
