Dunes City Home Addition Builder

Thinking about a home addition in Dunes 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 Lane County since 1969. Dunes City wraps around several coastal lakes and has strict shoreline development regulations — ADUs and garage additions must meet 100-ft riparian setbacks on lake-fronting lots, but interior parcels have more flexibility and the small city office processes permits quickly given the low application volume.

Building a home addition in Dunes City

Dunes City sits 60 mi west of Eugene on Highway 101 near Florence. Sits near the water, where shoreline setbacks and lakefront siting call for a builder who has navigated them before. Building permits here go through City of Dunes 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, Dunes City is known for Woahink Lake, Siltcoos Lake, and the Oregon Dunes NRA border, and we tailor every build to fit the lot, the neighborhood, and how you actually live.
