Custom Garage Builder in Dexter, Oregon
Custom Garage — built by Eugene’s garage & ADU master craftsman, serving Dexter since 1969.
Thinking about a custom garage in Dexter? A custom garage means covered parking, a real workshop, RV storage, or an apartment above — and Red Umbrella has been building garages, ADUs, and additions across Lane County since 1969. Dexter hugs the shoreline of Dexter Reservoir and many residential lots are within the flood hazard zone for the ACOE-managed reservoir — any ground-level garage addition requires a FEMA elevation certificate and potentially a no-rise certification before Lane County will issue a permit.
Building a custom garage in Dexter
Dexter sits 18 mi southeast of Eugene on Highway 58. Sits near the water, where shoreline setbacks and lakefront siting call for a builder who has navigated them before. Building permits here go through Lane County — a process we know well — and for a custom garage, that shapes the foundation, setbacks, and whether a detached shop or an attached garage fits the lot.
Locally, Dexter is known for Dexter Reservoir and the Middle Fork Willamette River, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Dexter custom garage questions
Can Red Umbrella add electrical to a garage in Dexter?
Yes — owner Bari Swartz holds an Oregon Supervisory Master Electrician license, so Red Umbrella can design and install garage electrical panels, circuits, lighting, outlets, and EV charger rough-ins without subcontracting the electrical work. This keeps scheduling tighter and accountability clear on every project.
Can I build a garage or ADU without a permit in Dexter to save money?
Building without required permits is not advisable — unpermitted structures in Dexter 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.
How do ADU rental returns compare to the cost of construction in Dexter?
Dexter 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. Red Umbrella does not guarantee rental rates, but can connect you with local property managers who know the Dexter market.
