ADU Builder Serving Leaburg, OR
ADU Builder — built by Eugene’s garage & ADU master craftsman, serving Leaburg since 1969.
Thinking about an ADU in Leaburg? A backyard ADU adds rental income, room for family, and lasting property value — and Red Umbrella has been building garages, ADUs, and additions across Lane County since 1969. Leaburg’s residential parcels line the McKenzie River canyon on both Highway 126 and the older McKenzie Highway; lots on the canyon floor are deep and narrow, making side-by-side garage additions impractical — tandem or front-facing single-bay designs with ADUs above are the local norm.
Building an ADU in Leaburg
Leaburg sits 26 mi east of Eugene on Highway 126. Follows a river corridor, so floodplain mapping and riparian setbacks are real factors we plan around from day one. Building permits here go through Lane County — 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, Leaburg is known for Leaburg Dam and PGE’s McKenzie River hydroelectric canal, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Leaburg ADU questions
Will an ADU increase my property taxes in Oregon?
In Oregon, adding an ADU triggers a reassessment only on the value added, not on the entire property, so your existing home’s assessed value is unaffected. The new ADU square footage is added to your tax roll, typically increasing property taxes by a few hundred dollars per year — far less than the rental income most Leaburg ADUs generate. Your Lane County Assessor can provide an estimate once construction is complete.
What permits are required for a garage conversion to ADU in Leaburg?
A garage-to-ADU conversion in Leaburg requires at minimum a building permit for change of occupancy and structural work, an electrical permit for new or upgraded circuits, and a plumbing permit for kitchen and bathroom rough-in. If a new utility connection or sub-meter is added, additional EWEB or City permits may apply. Red Umbrella prepares and submits all permit applications as part of the standard project scope.
What does “financing up to 120%” mean for a construction project?
Financing up to 120% of project cost means the loan can cover not only the construction contract amount but also an additional 20% to account for incidentals such as permits, system-development charges, landscaping after construction, or minor scope changes. This helps homeowners avoid out-of-pocket surprises during construction. HFS Financial, a lender partner of Red Umbrella, offers this type of product for qualifying borrowers.
