Jasper Garage Builder — Shops, RV Bays & More
Custom Garage — built by Eugene’s garage & ADU master craftsman, serving Jasper since 1969.
Thinking about a custom garage in Jasper? 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. Jasper is a quietly growing rural corridor popular with Eugene professionals seeking acreage close to town; lots are 1–3 acres on gently rolling terrain and Lane County permits process efficiently — detached ADUs and three-car garages are the most common projects Red Umbrella builds in this area.
Building a custom garage in Jasper
Jasper sits 10 mi southeast of Eugene off Jasper Road. 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 a custom garage, that shapes the foundation, setbacks, and whether a detached shop or an attached garage fits the lot.
Locally, Jasper is known for the Middle Fork Willamette River and Jasper Road rural corridor, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Jasper custom garage questions
Does a new garage in Jasper require a permit?
Yes — any detached garage over 200 square feet in Jasper requires a building permit from the City of Jasper 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.
What is Oregon’s contractor lien notice requirement?
Under Oregon Revised Statutes Chapter 87, contractors must provide homeowners with an “Information Notice to Owner” before beginning work; this notice explains your rights if subcontractors or suppliers file liens for unpaid amounts. Red Umbrella provides this notice as part of the contract paperwork before any work begins. Understanding your lien rights protects you even if all payments to Red Umbrella are made on time.
How do ADU rental returns compare to the cost of construction in Jasper?
Jasper 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 Jasper market.
