Convert Your Garage in Alsea, OR
Garage Conversion — built by Eugene’s garage & ADU master craftsman, serving Alsea since 1969.
Thinking about a garage conversion in Alsea? A garage conversion is the fastest, most affordable way to add finished living space — and Red Umbrella has been building garages, ADUs, and additions across Benton County since 1969. Alsea sits in one of Benton County’s most remote valleys, which means contractor lead times and material deliveries require planning a week or two further out than typical — we account for that upfront.
Building a garage conversion in Alsea
Alsea sits 47 mi northwest of Eugene via OR-34. Follows a river corridor, so floodplain mapping and riparian setbacks are real factors we plan around from day one. Building permits here go through Benton County — a process we know well — and for a garage conversion, that shapes insulation, egress, and whether the existing slab and walls can carry a full living space.
Locally, Alsea is known for Alsea River (premier steelhead fishery), Hayden Covered Bridge, OR-34, Alsea Charter School K–12, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Alsea garage conversion questions
Do I lose parking if I convert my garage to an ADU in Alsea?
Under current City of Alsea ADU rules, properties that convert a garage into an ADU are not required to replace the lost parking space. This is a significant policy advantage that makes garage conversions one of the most accessible ADU paths for Alsea homeowners. Check with Red Umbrella if your property is in a special district or has an existing conditional-use approval that may impose different parking terms.
Is an ORS Chapter 87 lien notice required for my project?
Yes — Oregon law requires licensed contractors to deliver an “Information Notice to Owner About Construction Liens” before starting any improvement to residential property under ORS 87.093. This protects homeowners by disclosing that subcontractors and suppliers may have lien rights even when the general contractor is paid in full. Red Umbrella includes this notice in every contract packet.
How do ADU rental returns compare to the cost of construction in Alsea?
Alsea 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 Alsea market.
