Blodgett ADU Builder
ADU Builder — built by Eugene’s garage & ADU master craftsman, serving Blodgett since 1969.
Thinking about an ADU in Blodgett? A backyard ADU adds rental income, room for family, and lasting property value — and Red Umbrella has been building garages, ADUs, and additions across Benton County since 1969. Blodgett’s crossroads location in the Coast Range foothills offers the serenity of rural Benton County with US-20 access for material deliveries — remote-feeling but not inaccessible.
Building an ADU in Blodgett
Blodgett sits 63 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 an ADU, that shapes how utilities connect and whether a detached cottage or an attached unit fits best.
Locally, Blodgett is known for US-20 & OR-180 junction, Tumtum River confluence with Marys River, Coast Range foothills, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Blodgett ADU questions
How big can an ADU be in Blodgett, Oregon?
In Blodgett, an ADU can be up to 800 square feet or 10% of the total lot area, whichever is less. Attached ADUs and garage-conversion ADUs follow slightly different formulas, so your specific zoning district and lot size determine the exact maximum. Red Umbrella’s team reviews your parcel during a free consultation and calculates the largest unit your site can accommodate.
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.
Does building an ADU or addition increase my home’s value?
Adding an ADU or a well-designed addition generally increases a home’s resale value in the Blodgett market, though the increase depends on location, finishes, and buyer demand. An ADU that generates rental income is especially appealing to buyers who can offset their mortgage with rent. Red Umbrella builds to quality standards that hold up over time and support strong appraisals.
