Room Additions & Suites in Oakridge, OR
Home Additions — built by Eugene’s garage & ADU master craftsman, serving Oakridge since 1969.
Thinking about a home addition in Oakridge? 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 Lane County since 1969. Oakridge sits at roughly 1,200 ft elevation in a narrow river canyon, so lots are typically long and narrow — many homeowners build detached garage-workshop combinations that double as gear storage for mountain biking and skiing, sized to house trailers and fit the tight side-yard setbacks on canyon-edge parcels.
Building a home addition in Oakridge
Oakridge sits 40 mi southeast of Eugene on Highway 58. Is up in the foothills, where slope, snow load, and wildfire-resilient construction all come into the plan. Building permits here go through City of Oakridge — 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, Oakridge is known for the Willamette Pass ski area and the North Fork Middle Fork Willamette River trail network, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Oakridge home addition questions
Do I need a permit for a home addition in Oakridge?
Yes — any structural addition to a home in Oakridge 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 Oakridge Development Services, and manages inspections through final sign-off. Homeowners do not need to deal with the permit office directly.
Does Red Umbrella pull permits for all of its work?
Yes — Red Umbrella pulls all required building, electrical, plumbing, and mechanical permits for every project. Bari Swartz holds Oregon Contractor’s license CCB #210412 and a Supervisory Master Electrician credential, covering structural and electrical work without additional subcontractors. Unpermitted construction creates serious liability for homeowners and is not something Red Umbrella does.
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.
