Room Additions & Suites in Mill City, OR
Home Additions — built by Eugene’s garage & ADU master craftsman, serving Mill City since 1969.
Thinking about a home addition in Mill City? 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 Linn County since 1969. Mill City’s canyon setting and mountain climate mean roofing and siding choices for garages differ from valley projects — we spec materials that handle the higher snowload and moisture here.
Building a home addition in Mill City
Mill City sits 70 mi north-northeast of Eugene via I-5 & OR-22. 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 Mill City — 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, Mill City is known for North Santiam River gorge, OR-22 Cascade corridor, 1,100 ft elevation, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Mill City home addition questions
What home additions does Red Umbrella build in Mill City?
Red Umbrella builds room additions, master suite additions, kitchen expansions, family-room additions, covered porches, and full second-story additions throughout Lane, Linn, Benton, and Douglas counties. Every addition is designed to match the existing home’s roofline, exterior materials, and interior finishes so the project looks original rather than tacked-on. Bari Swartz personally reviews each project plan before construction begins.
What is Oregon’s contractor lien notice requirement?
Under Oregon Revised Statutes Chapter 87, contractors must provide homeowners with an “Information Notice to Owner” before beginning work; this notice explains your rights if subcontractors or suppliers file liens for unpaid amounts. Red Umbrella provides this notice as part of the contract paperwork before any work begins. Understanding your lien rights protects you even if all payments to Red Umbrella are made on time.
What is HFS Financial and how does it work for home improvements in Oregon?
HFS Financial is a lending marketplace specializing in home-improvement loans, and Red Umbrella is an approved contractor partner. HFS can finance projects up to 120% of the project cost — meaning closing costs and some associated expenses can be rolled in — with loan amounts up to $500,000 and without requiring home equity or a new first mortgage. Loan terms, rates, and approval requirements vary; Red Umbrella can connect you with an HFS representative after your free consultation.
