ADU Builder Serving Jasper, OR
ADU Builder — built by Eugene’s garage & ADU master craftsman, serving Jasper since 1969.
Thinking about an ADU in Jasper? A backyard ADU adds rental income, room for family, and lasting property value — and Red Umbrella has been building garages, ADUs, and additions across Lane County since 1969. Jasper is a quietly growing rural corridor popular with Eugene professionals seeking acreage close to town; lots are 1–3 acres on gently rolling terrain and Lane County permits process efficiently — detached ADUs and three-car garages are the most common projects Red Umbrella builds in this area.
Building an ADU in Jasper
Jasper sits 10 mi southeast of Eugene off Jasper Road. Follows a river corridor, so floodplain mapping and riparian setbacks are real factors we plan around from day one. Building permits here go through Lane 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, Jasper is known for the Middle Fork Willamette River and Jasper Road rural corridor, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Jasper ADU questions
Can I build an ADU on a lot that already has a duplex in Jasper?
Oregon state law (SB 1051 and subsequent updates) expanded ADU rights broadly, and Jasper’s code reflects that, but ADU eligibility on multi-family lots like duplexes depends on the specific zoning district and lot size. Red Umbrella’s team reviews your parcel during a free consultation and checks with Jasper Development Services when a lot’s eligibility is borderline. Don’t assume your lot qualifies or doesn’t without a professional review.
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.
