ADU Builder Serving Roseburg, OR
ADU Builder — built by Eugene’s garage & ADU master craftsman, serving Roseburg since 1969.
Thinking about an ADU in Roseburg? A backyard ADU adds rental income, room for family, and lasting property value — and Red Umbrella has been building garages, ADUs, and additions across Douglas County since 1969. As the Douglas County seat and regional hub, Roseburg has a well-staffed building department with consistent turnaround times — ideal for homeowners who want a predictable ADU permit schedule.
Building an ADU in Roseburg
Roseburg sits 73 mi south of Eugene via I-5. Sits in the Umpqua Valley with established neighborhoods and city-run permitting, so a project moves on a predictable timeline. Building permits here go through City of Roseburg — a process we know well — and for an ADU, that shapes how utilities connect and whether a detached cottage or an attached unit fits best.
Locally, Roseburg is known for North Umpqua & South Umpqua Rivers, River Forks Park, Stewart Park, Umpqua Valley wine region, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Roseburg ADU questions
Can I build an ADU on a lot that already has a duplex in Roseburg?
Oregon state law (SB 1051 and subsequent updates) expanded ADU rights broadly, and Roseburg’s code reflects that, but ADU eligibility on multi-family lots like duplexes depends on the specific zoning district and lot size. Red Umbrella’s team reviews your parcel during a free consultation and checks with Roseburg Development Services when a lot’s eligibility is borderline. Don’t assume your lot qualifies or doesn’t without a professional review.
What is the timeline from consultation to permit approval for an ADU in Roseburg?
After your free consultation and once Red Umbrella prepares drawings (typically 2–4 weeks), the permit application is submitted to City of Roseburg Development Services, where plan review takes approximately 6–16 weeks for residential projects depending on current workload. Total time from first call to permit-in-hand is usually 3–5 months. Red Umbrella tracks your application status and responds promptly to any reviewer comments to minimize delays.
How do ADU rental returns compare to the cost of construction in Roseburg?
Roseburg arean ADUs commonly rent for $1,200–$2,000 per month depending on size, location, and finishes, which can generate $14,000–$24,000 per year in gross rental income. At those rates, a $60,000 garage-conversion ADU can recoup its full cost within 3–5 years in rental income alone. Red Umbrella does not guarantee rental rates, but can connect you with local property managers who know the Roseburg market.
