Red Umbrella is the rare Eugene builder that does both garages and ADUs — and the bridge between them. From a detached shop or custom garage to a full backyard ADU or garage conversion, we design, permit, and build it under one roof.
Four core services, one experienced crew, and a single point of accountability from first sketch to final walkthrough.
Add a livable, rentable accessory dwelling unit — detached, attached, or above a garage. Rental income, guest space, or room for family.
Explore ADUs →Turn an underused garage into a bedroom, office, in-law suite, or full garage-to-ADU — our highest-value specialty.
Convert my garage →Detached & attached, 1–4 car, shops, RV bays, and garages with an apartment or loft. Any size, any roof style, built to last.
Build a garage →Room additions, second stories, and expansions that blend seamlessly with your existing home and add lasting value.
Add on →Most ADU shops don't do custom garages. Most garage shops don't do ADUs. Red Umbrella owns the bridge — including the smartest path of all: turning your garage into an ADU.
One licensed crew, one point of contact, one accountable team — no juggling separate contractors.
Structural Insulated Panels mean a tighter, warmer building envelope, lower energy bills, and a faster build than stick frame.
Owner Bari Swartz is a Supervisory Master Electrician — your wiring is done right, in-house, and to code.
We know City of Eugene, City of Springfield, and Lane County permitting — and we confirm what your specific lot allows.
"Red Umbrella built our detached garage with a studio above it and handled every permit. Bari's crew was on time, tidy, and the electrical was flawless."
"We converted our garage into an ADU for my mom. They walked us through the zoning, the design, and the budget honestly. Couldn't be happier."
"From the first quote to the final walkthrough, everything was clear and on budget. The SIP-panel shop they built is warm and dry year-round."
We visit your property, assess the lot, and talk through what's possible and what it should cost — no pressure.
We design the right garage, ADU, or addition for your lot and budget, with CAD drawings and a clear scope.
We manage the City of Eugene, Springfield, or Lane County permitting so you don't have to chase paperwork.
Our licensed crew builds it — typically 4–6 months — and walks you through every detail at completion.
Spread the cost of your garage, ADU, or addition over time with quick, simple financing options through our partner, HFS Financial.
Based at 254 Hardy Ave in Eugene, we serve homeowners throughout the southern Willamette Valley.
Tell us a little about your garage, ADU, or addition and Bari will get back to you — usually within one business day. No scripts, no pressure, just honest answers.
It varies by size, site, and finishes, but most ground-up ADUs in the Eugene area run roughly $120,000–$220,000, while a garage-to-ADU conversion is often $50,000–$80,000 — typically the most affordable path to a livable unit. We'll give you a clear, honest estimate for your specific lot.
Under current Oregon rules, ADUs generally do not require the owner to live on-site, and no additional off-street parking is required. Local rules do change, so we confirm the current City of Eugene and Lane County requirements for your property before we design.
A garage conversion is usually faster and less expensive, but you give up the garage and may trigger code upgrades. A new detached ADU costs more but adds a separate, private unit without losing your parking. As a builder that does both, we'll give you a straight answer for your situation.
Traditional stick framing is built board-by-board on site. SIP (Structural Insulated Panels) are pre-engineered panels with a solid foam core — they go up faster, seal tighter, and deliver better energy efficiency. We build both and will recommend what fits your project and budget.
