Eugene Garage Builder — Shops, RV Bays & More
Custom Garage — built by Eugene’s garage & ADU master craftsman, serving Eugene since 1969.
Thinking about a custom garage in Eugene? A custom garage means covered parking, a real workshop, RV storage, or an apartment above — and Red Umbrella has been building garages, ADUs, and additions across Lane County since 1969. Eugene’s urban-infill emphasis and ADU-friendly R-1 zoning make it one of the easier places in the valley to add a garage conversion or detached ADU — the city actively encourages density without displacing neighborhood character.
Building a custom garage in Eugene
Eugene the heart of Lane County on I-5 at the Willamette Valley floor. Sits on the Willamette Valley floor with established neighborhoods and city-run permitting, so a project moves on a predictable timeline. Building permits here go through City of Eugene — a process we know well — and for a custom garage, that shapes the foundation, setbacks, and whether a detached shop or an attached garage fits the lot.
Locally, Eugene is known for University of Oregon campus and the Willamette River path system, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Eugene custom garage questions
Does a new garage in Eugene require a permit?
Yes — any detached garage over 200 square feet in Eugene requires a building permit from the City of Eugene or the applicable county (Lane, Linn, Benton, or Douglas). Red Umbrella prepares and submits all permit documents, coordinates inspections, and delivers a final Certificate of Occupancy or final inspection sign-off before the project is considered complete.
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.
