Alpine Garage Builder — Shops, RV Bays & More
Custom Garage — built by Eugene’s garage & ADU master craftsman, serving Alpine since 1969.
Thinking about a custom garage in Alpine? 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 Benton County since 1969. Alpine’s hilltop setting among Coast Range vineyards means your garage or addition benefits from long views — and benefits from a builder who plans drainage for hillside lots, not flat-valley ones.
Building a custom garage in Alpine
Alpine sits 35 mi northwest of Eugene via OR-99W & local roads. Is surrounded by working farmland where efu zoning and generous setbacks shape what — and where — you can build. Building permits here go through Benton 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, Alpine is known for Alpine Tavern (est. 1936), OSU Woodhall Vineyard, Alpine Century Bike Ride, Alsea Falls BLM access, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Alpine custom garage questions
Does a new garage in Alpine require a permit?
Yes — any detached garage over 200 square feet in Alpine requires a building permit from the City of Alpine 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.
