Lyons ADU Builder
ADU Builder — built by Eugene’s garage & ADU master craftsman, serving Lyons since 1969.
Thinking about an ADU in Lyons? 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. Lyons sits where the canyon narrows along the North Santiam, meaning sloped lots are common and garage foundations often require engineered cut-and-fill rather than a simple slab.
Building an ADU in Lyons
Lyons sits 65 mi north-northeast of Eugene via I-5 & OR-22. 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 Lyons — 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, Lyons is known for North Santiam River, OR-22 North Santiam Highway, Santiam State Forest, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Lyons ADU questions
How big can an ADU be in Lyons, Oregon?
In Lyons, an ADU can be up to 800 square feet or 10% of the total lot area, whichever is less. Attached ADUs and garage-conversion ADUs follow slightly different formulas, so your specific zoning district and lot size determine the exact maximum. Red Umbrella’s team reviews your parcel during a free consultation and calculates the largest unit your site can accommodate.
What is the timeline from consultation to permit approval for an ADU in Lyons?
After your free consultation and once Red Umbrella prepares drawings (typically 2–4 weeks), the permit application is submitted to City of Lyons 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.
How do ADU rental returns compare to the cost of construction in Lyons?
Lyons arean ADUs commonly rent for $1,200–$2,000 per month depending on size, location, and finishes, which can generate $14,000–$24,000 per year in gross rental income. At those rates, a $60,000 garage-conversion ADU can recoup its full cost within 3–5 years in rental income alone. Red Umbrella does not guarantee rental rates, but can connect you with local property managers who know the Lyons market.
