Room Additions & Suites in Westfir, OR
Home Additions — built by Eugene’s garage & ADU master craftsman, serving Westfir since 1969.
Thinking about a home addition in Westfir? 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. Westfir is Lane County’s smallest incorporated city — a former timber town with roughly 200 residents — where lots are generous and the city permit process is straightforward but infrequently exercised, so builders should plan extra lead time for inspections scheduled around the building official’s part-time hours.
Building a home addition in Westfir
Westfir sits 38 mi southeast of Eugene off Highway 58. Is up in the foothills, where slope, snow load, and wildfire-resilient construction all come into the plan. Building permits here go through City of Westfir — 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, Westfir is known for the North Fork Middle Fork Willamette River and the Office Bridge covered bridge, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Westfir home addition questions
How much does a home addition cost in Westfir, Oregon?
Home additions in Westfir typically range from $150 to $300 per square foot depending on complexity, finishes, and whether plumbing or electrical upgrades are needed. A 200-square-foot master bedroom addition might run $35,000–$65,000; a 400-square-foot family room with a bathroom runs $75,000–$130,000 or more. Red Umbrella provides a free on-site estimate so you have an accurate number before any design cost is incurred.
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 Red Umbrella require a large deposit upfront?
Red Umbrella’s payment schedule is outlined in the written contract before work begins, typically structured around project milestones rather than a single large upfront payment. Oregon law limits contractor deposits on residential projects, and Red Umbrella follows those rules. Your contract will show exactly when each payment is due relative to construction progress.
