Bethel ADU Builder
ADU Builder — built by Eugene’s garage & ADU master craftsman, serving Bethel since 1969.
Thinking about an ADU in Bethel? 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. Bethel is a working-class west Eugene unincorporated district where many homeowners are adding ADUs for rental income — Lane County’s ADU permit pathway is well-tested here, but planners flag any project near the federally protected west Eugene wetland system, so a wetland determination is worth ordering early.
Building an ADU in Bethel
Bethel sits 3 mi west of downtown Eugene. Blends established suburban lots with larger parcels on its edges — a familiar mix for siting a new build. 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, Bethel is known for the west Eugene wetlands and West 11th Avenue commercial corridor, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Bethel ADU questions
What is a junior ADU (JADU) and can I build one in Bethel?
A junior ADU is an ADU created entirely within an existing single-family home — often a converted bedroom, basement, or attached garage — and is capped at 500 square feet in Oregon. JADUs are generally faster to permit and less expensive than full detached ADUs because they use the existing structure’s foundation, roof, and often its utility connections. Red Umbrella can assess whether your home’s existing footprint qualifies and design a JADU that meets Bethel code.
What permits are required for a garage conversion to ADU in Bethel?
A garage-to-ADU conversion in Bethel requires at minimum a building permit for change of occupancy and structural work, an electrical permit for new or upgraded circuits, and a plumbing permit for kitchen and bathroom rough-in. If a new utility connection or sub-meter is added, additional EWEB or City permits may apply. Red Umbrella prepares and submits all permit applications as part of the standard project scope.
How do ADU rental returns compare to the cost of construction in Bethel?
Bethel 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 Bethel market.
