Fall Creek ADU Builder
ADU Builder — built by Eugene’s garage & ADU master craftsman, serving Fall Creek since 1969.
Thinking about an ADU in Fall Creek? 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. Fall Creek occupies a steep forested corridor below the USACE-managed Fall Creek Reservoir dam; buildable lots are limited and topographically challenging, so most garage additions here are attached structures carved into hillside foundations — cost-per-square-foot runs meaningfully higher than valley-floor projects.
Building an ADU in Fall Creek
Fall Creek sits 25 mi southeast of Eugene via Jasper-Lowell Road. Sits near the water, where shoreline setbacks and lakefront siting call for a builder who has navigated them before. 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, Fall Creek is known for Fall Creek Reservoir and the Willamette National Forest entry, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Fall Creek ADU questions
What is an ADU and can I build one on my Fall Creek property?
An ADU (accessory dwelling unit) is a second, self-contained home on the same lot as a primary residence, and most Fall Creek residential lots are eligible to have one. Under current City of Fall Creek rules there is no owner-occupancy requirement, so landlords and investors can build ADUs without living on site. Maximum size is 800 square feet or 10% of the lot area, whichever is smaller, and most properties need no additional parking space under current code. Red Umbrella offers free on-site consultations to confirm your lot’s specific eligibility.
Can I build a garage or ADU without a permit in Fall Creek to save money?
Building without required permits is not advisable — unpermitted structures in Fall Creek can be subject to stop-work orders, fines, mandatory demolition, or expensive retroactive permitting when the property is sold. Lenders and title companies routinely flag unpermitted square footage during real estate transactions, making the property harder to sell or refinance. Red Umbrella only builds permitted structures; the cost of permitting is small relative to the risk of going without.
Can I finance Fall Creek system-development charges for an ADU?
Yes — SDCs (which vary by city and county) can be financed through programs like HFS Financial rather than paid out of pocket at permit issuance. Including SDCs in your project loan keeps cash available for other needs and spreads the cost across the loan term. Red Umbrella will help you understand how SDCs fit into your overall project budget.
