ADU Builder Serving Mapleton, OR

Thinking about an ADU in Mapleton? A backyard ADU adds rental income, room for family, and lasting property value — and Red Umbrella has been building garages, ADUs, and additions across Lane County since 1969. Mapleton’s larger lots and rural parcels can often fit a detached cottage for family or a long-term renter, sited around the septic system and above any mapped floodplain.

Building an ADU 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 an ADU, that shapes how utilities connect and whether a detached cottage or an attached unit fits best.

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.

• Building since 1969 — you work directly with Bari, not a sales rep or a rotating cast of subs.
