Philomath Garage-to-Living-Space Conversions
Garage Conversion — built by Eugene’s garage & ADU master craftsman, serving Philomath since 1969.
Thinking about a garage conversion in Philomath? 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. Philomath’s position at the foot of the Coast Range means lots on the west side of town carry steeper grades, making garage siting and drainage planning more involved than on the valley floor.
Building a garage conversion in Philomath
Philomath sits 53 mi north-northwest of Eugene via I-5 & US-20. Blends established suburban lots with larger parcels on its edges — a familiar mix for siting a new build. Building permits here go through City of Philomath — 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, Philomath is known for Marys Peak (4,097 ft, highest point in the Oregon Coast Range), Marys River Park, Philomath Frolic & Rodeo, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

How do ADU rental returns compare to the cost of construction in Philomath?
Philomath 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.
