Mapleton Garage Builder — Shops, RV Bays & More
Custom Garage — built by Eugene’s garage & ADU master craftsman, building across Lane County since 1969.
Thinking about a custom garage in Mapleton? 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. With heavy Coast Range rain, a Mapleton garage or shop is built to keep boats, trucks and tools dry: steeper roofs, wide overhangs, good gutters and a slab that drains away from the doors.
Building a custom garage in Mapleton
Mapleton sits about 38 miles west of Eugene as the crow flies, where Highway 126 meets Highway 36 on the Siuslaw River. Lots here range from Siuslaw river bottomland to steep timbered hillsides, so floodplain mapping, slope and storm drainage are worked out 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, Mapleton is known for the Siuslaw River, the Sweet Creek Falls trail and the surrounding Siuslaw National Forest, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Why Mapleton homeowners choose Red Umbrella
- Garages and ADUs under one roof — the rare shop that masters both, so a garage-with-a-suite is one project, one crew.
- Electrical planned from day one — owner Bari Swartz, formerly a Master Electrical Contractor in several states, plans the wiring with the floor plan.
- Building since 1969 — you work directly with Bari, not a sales rep or a rotating cast of subs.
- Permits handled & up to 120% financing — we know Lane County and make the whole path simple.
Mapleton custom garage questions
What size garage or shop makes sense in Mapleton?
It depends on what has to fit. Mapleton owners tend to ask for a long bay for a drift boat or trailer, a workbench wall and a covered side for firewood. Most projects land between a two-car garage and a larger shop with a tall bay; Bari measures the site, checks setbacks with Lane County and prices two or three sizes so you can compare.
Who issues building permits in Mapleton?
There is no city permit office in Mapleton; applications, plan review and inspections all run through Lane County’s Land Management Division in Eugene. Red Umbrella files the paperwork and meets the inspectors on site, so you do not have to make the drive.
Can you build on a sloped, timbered lot in Mapleton?
Yes. Hillside lots above the Siuslaw are common here, and they usually mean a site visit before any drawing: Bari looks at access for equipment, where water runs in a storm, how much excavation the foundation needs and how close the trees are, then prices the site work into the written scope.
