Room Additions & Suites in Halsey, OR
Home Additions — built by Eugene’s garage & ADU master craftsman, serving Halsey since 1969.
Thinking about a home addition in Halsey? 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. Halsey’s expansive agricultural lots make detached garages and shop buildings straightforward — setbacks from property lines are rarely a constraint on these generous parcels.
Building a home addition in Halsey
Halsey sits 28 mi north of Eugene via I-5. Is surrounded by working farmland where efu zoning and generous setbacks shape what — and where — you can build. Building permits here go through City of Halsey — 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, Halsey is known for OR-99E & OR-228 junction, flat grass-seed and grain farm country, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Halsey home addition questions
What home additions does Red Umbrella build in Halsey?
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 permits are required for a garage conversion to ADU in Halsey?
A garage-to-ADU conversion in Halsey requires at minimum a building permit for change of occupancy and structural work, an electrical permit for new or upgraded circuits, and a plumbing permit for kitchen and bathroom rough-in. If a new utility connection or sub-meter is added, additional EWEB or City permits may apply. Red Umbrella prepares and submits all permit applications as part of the standard project scope.
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.
