Millersburg ADU Builder
ADU Builder — built by Eugene’s garage & ADU master craftsman, serving Millersburg since 1969.
Thinking about an ADU in Millersburg? A backyard ADU adds rental income, room for family, and lasting property value — and Red Umbrella has been building garages, ADUs, and additions across Linn County since 1969. Millersburg splits electrical permits to Linn County just like Lebanon does — knowing which inspector to call for which trade saves weeks on a garage or addition project here.
Building an ADU in Millersburg
Millersburg sits 28 mi north of Eugene via I-5. Blends established suburban lots with larger parcels on its edges — a familiar mix for siting a new build. Building permits here go through City of Millersburg — 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, Millersburg is known for ATI Specialty Alloys industrial campus, I-5 north Albany, incorporated 1974 to protect industrial zoning, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Millersburg ADU questions
What is a junior ADU (JADU) and can I build one in Millersburg?
A junior ADU is an ADU created entirely within an existing single-family home — often a converted bedroom, basement, or attached garage — and is capped at 500 square feet in Oregon. JADUs are generally faster to permit and less expensive than full detached ADUs because they use the existing structure’s foundation, roof, and often its utility connections. Red Umbrella can assess whether your home’s existing footprint qualifies and design a JADU that meets Millersburg code.
What is the timeline from consultation to permit approval for an ADU in Millersburg?
After your free consultation and once Red Umbrella prepares drawings (typically 2–4 weeks), the permit application is submitted to City of Millersburg 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.
Can I finance Millersburg system-development charges for an ADU?
Yes — SDCs (which vary by city and county) can be financed through programs like HFS Financial rather than paid out of pocket at permit issuance. Including SDCs in your project loan keeps cash available for other needs and spreads the cost across the loan term. Red Umbrella will help you understand how SDCs fit into your overall project budget.
