Roseburg Home Addition Builder
Home Additions — built by Eugene’s garage & ADU master craftsman, serving Roseburg since 1969.
Thinking about a home addition in Roseburg? A seamless addition adds the room you need without the cost and upheaval of moving — 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 a home addition 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 a home addition, that shapes how the new space ties into existing rooflines, the foundation, and the permit path.
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 home addition questions
Do I need a permit for a home addition in Roseburg?
Yes — any structural addition to a home in Roseburg requires a building permit, and additions that include new plumbing, electrical, or mechanical work require additional trade permits. Red Umbrella prepares all permit applications, submits plans to the City of Roseburg Development Services, and manages inspections through final sign-off. Homeowners do not need to deal with the permit office directly.
What counties does Red Umbrella serve?
Red Umbrella serves Lane, Linn, Benton, and Douglas counties in Oregon, with the majority of projects in the Roseburg–Springfield metro area. Projects in outlying areas of those counties are considered on a case-by-case basis during the free consultation. Call (541) 515-3843 or request a consultation at the website to confirm service to your address.
How much does it cost to build an ADU or addition, and can I finance it?
Construction costs range from roughly $50,000 for a garage conversion to $230,000 or more for a new detached ADU, depending on size and scope. Red Umbrella works with HFS Financial, which offers financing up to 120% of project cost to cover construction and some soft costs without requiring home equity.
