Wren Garage-to-Living-Space Conversions
Garage Conversion — built by Eugene’s garage & ADU master craftsman, serving Wren since 1969.
Thinking about a garage conversion in Wren? 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. Wren has a Benton County community plan that shapes allowable land uses — we review those rural-UGB standards before design so your garage or shop doesn’t trigger a variance.
Building a garage conversion in Wren
Wren sits 60 mi northwest of Eugene via I-5 & US-20. Is rural and largely unincorporated, which usually means county-level permitting, septic siting, and room for larger shops and outbuildings. 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, Wren is known for Marys River, US-20 & OR-223 junction, established via Oregon Pacific Railroad 1886, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Wren garage conversion questions
Will my homeowner’s insurance cover a garage conversion or ADU?
Standard homeowner’s insurance policies may not automatically cover a newly converted or added ADU, especially if it is rented — you should notify your insurer before or immediately after construction. Many insurers offer a landlord or “dwelling fire” endorsement for rental ADUs at modest additional premium. Red Umbrella recommends discussing coverage with your insurance agent during the planning phase, not after construction is complete.
Can I build a garage or ADU without a permit in Wren to save money?
Building without required permits is not advisable — unpermitted structures in Wren can be subject to stop-work orders, fines, mandatory demolition, or expensive retroactive permitting when the property is sold. Lenders and title companies routinely flag unpermitted square footage during real estate transactions, making the property harder to sell or refinance. Red Umbrella only builds permitted structures; the cost of permitting is small relative to the risk of going without.
What is HFS Financial and how does it work for home improvements in Oregon?
HFS Financial is a lending marketplace specializing in home-improvement loans, and Red Umbrella is an approved contractor partner. HFS can finance projects up to 120% of the project cost — meaning closing costs and some associated expenses can be rolled in — with loan amounts up to $500,000 and without requiring home equity or a new first mortgage. Loan terms, rates, and approval requirements vary; Red Umbrella can connect you with an HFS representative after your free consultation.
