Convert Your Garage in Monroe, OR
Garage Conversion — built by Eugene’s garage & ADU master craftsman, serving Monroe since 1969.
Thinking about a garage conversion in Monroe? 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. Monroe is the closest Benton County community to Eugene along the 99W corridor — short drive for our crew and a straightforward city permit make projects here refreshingly efficient.
Building a garage conversion in Monroe
Monroe sits 23 mi north of Eugene via OR-99W. Is surrounded by working farmland where efu zoning and generous setbacks shape what — and where — you can build. Building permits here go through City of Monroe — 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, Monroe is known for Long Tom River, OR-99W corridor, Christmas tree farms and wine-grape orchards, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Monroe garage conversion questions
How much does it cost to convert a garage into living space in Monroe?
Converting a garage to livable space in Monroe 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.
Does Red Umbrella pull permits for all of its work?
Yes — Red Umbrella pulls all required building, electrical, plumbing, and mechanical permits for every project. Bari Swartz holds Oregon Contractor’s license CCB #210412 and a Supervisory Master Electrician credential, covering structural and electrical work without additional subcontractors. Unpermitted construction creates serious liability for homeowners and is not something Red Umbrella does.
What does “financing up to 120%” mean for a construction project?
Financing up to 120% of project cost means the loan can cover not only the construction contract amount but also an additional 20% to account for incidentals such as permits, system-development charges, landscaping after construction, or minor scope changes. This helps homeowners avoid out-of-pocket surprises during construction. HFS Financial, a lender partner of Red Umbrella, offers this type of product for qualifying borrowers.
