Cheshire Home Addition Builder
Home Additions — built by Eugene’s garage & ADU master craftsman, serving Cheshire since 1969.
Thinking about a home addition in Cheshire? A seamless addition adds the room you need without the cost and upheaval of moving — and Red Umbrella has been building garages, ADUs, and additions across Lane County since 1969. Cheshire sits in the flat Long Tom River valley surrounded by active dairy farms; residential lots within the community are a mix of village-era parcels and small acreages, and Lane County’s rural residential zoning allows combination garage-shop buildings up to 3,000 sq ft without conditional use review.
Building a home addition in Cheshire
Cheshire sits 22 mi northwest of Eugene on Highway 36. Is surrounded by working farmland where efu zoning and generous setbacks shape what — and where — you can build. Building permits here go through Lane County — a process we know well — and for a home addition, that shapes how the new space ties into existing rooflines, the foundation, and the permit path.
Locally, Cheshire is known for the Long Tom River valley and Highway 36 dairy corridor, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Cheshire home addition questions
Do I need a permit for a home addition in Cheshire?
Yes — any structural addition to a home in Cheshire requires a building permit, and additions that include new plumbing, electrical, or mechanical work require additional trade permits. Red Umbrella prepares all permit applications, submits plans to the City of Cheshire Development Services, and manages inspections through final sign-off. Homeowners do not need to deal with the permit office directly.
Is an ORS Chapter 87 lien notice required for my project?
Yes — Oregon law requires licensed contractors to deliver an “Information Notice to Owner About Construction Liens” before starting any improvement to residential property under ORS 87.093. This protects homeowners by disclosing that subcontractors and suppliers may have lien rights even when the general contractor is paid in full. Red Umbrella includes this notice in every contract packet.
How do ADU rental returns compare to the cost of construction in Cheshire?
Cheshire 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 Cheshire market.
