Portland's Experienced ADU Builder — Shelter Solutions
Shelter Solutions is a Portland, Oregon-based ADU contractor with a long-standing reputation for delivering thoughtful, high-quality accessory dwelling units throughout the Portland Metro area. Founded in 1997 by Joe Robertson — widely regarded as one of the pioneers of ADU construction in the region — the company has completed over 250 ADUs for homeowners seeking to age in place, house family members, generate rental income, or simply expand their living space.
Today, Shelter Solutions operates under the leadership of Mark Beirwagen, whose background as a custom home builder and commitment to exceptional customer service makes him a natural fit to carry forward the legacy Joe built. From the office to the field, their team of passionate designers, project developers, selection coordinators, and project managers work together to guide clients through every stage of the process.
As a full-service accessory dwelling unit builder, Shelter Solutions handles projects ranging from detached ADU construction and backyard cottage builds to in-law suite and granny flat development. Their work spans a wide variety of use cases, including guest houses, home offices, studio spaces, entertainment areas, home gyms, and long-term income-producing rental units.

Transparency and clear communication are central to how they operate. Shelter Solutions emphasizes honest cost estimates, realistic timelines, and a collaborative approach that keeps homeowners informed and empowered throughout the entire build.
