Winston Garage-to-Living-Space Conversions
Garage Conversion — built by Eugene’s garage & ADU master craftsman, serving Winston since 1969.
Thinking about a garage conversion in Winston? 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 Douglas County since 1969. Winston is defined by Wildlife Safari, which draws regional traffic and has raised neighborhood property values steadily — an ADU here has genuine rental potential beyond just family use.
Building a garage conversion in Winston
Winston sits 80 mi south of Eugene via I-5. Sits in the Umpqua Valley with established neighborhoods and city-run permitting, so a project moves on a predictable timeline. Building permits here go through City of Winston — 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, Winston is known for Wildlife Safari (600-acre drive-through park, 4.5-mi loop), South Umpqua River, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Winston garage conversion questions
How much does it cost to convert a garage into living space in Winston?
Converting a garage to livable space in Winston typically costs $50,000–$85,000 for a full ADU-quality conversion with insulation, HVAC, kitchen, bathroom, and finishes. A simpler conversion to a non-kitchen bonus room or bedroom runs less — roughly $20,000–$45,000. Red Umbrella gives you an exact number after a free walk-through of the existing garage.
What is the timeline from consultation to permit approval for an ADU in Winston?
After your free consultation and once Red Umbrella prepares drawings (typically 2–4 weeks), the permit application is submitted to City of Winston Development Services, where plan review takes approximately 6–16 weeks for residential projects depending on current workload. Total time from first call to permit-in-hand is usually 3–5 months. Red Umbrella tracks your application status and responds promptly to any reviewer comments to minimize delays.
How much does it cost to build an ADU or addition, and can I finance it?
Construction costs range from roughly $50,000 for a garage conversion to $230,000 or more for a new detached ADU, depending on size and scope. Red Umbrella works with HFS Financial, which offers financing up to 120% of project cost to cover construction and some soft costs without requiring home equity. A free on-site estimate gives you the exact number before you apply for financing.
