Riddle ADU Builder

Thinking about an ADU in Riddle? A backyard ADU adds rental income, room for family, and lasting property value — and Red Umbrella has been building garages, ADUs, and additions across Douglas County since 1969. Riddle’s nickel-mining past left behind a tight-knit working-class community where practical shop buildings and garages fit right in — we build for function first here, not curb appeal.

Building an ADU in Riddle

Riddle sits 85 mi south of Eugene via I-5. Is rural and largely unincorporated, which usually means county-level permitting, septic siting, and room for larger shops and outbuildings. Building permits here go through City of Riddle — 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, Riddle is known for Cow Creek valley, historic nickel-mining heritage (sole U.S. commercial nickel site), South Umpqua tributary, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Why Riddle 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.
• Master Electrician in-house — owner Bari Swartz wires it himself, to code, no waiting on a sub.
• 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 City of Riddle and make the whole path simple.
