Room Additions & Suites in Creswell, OR
Home Additions — built by Eugene’s garage & ADU master craftsman, serving Creswell since 1969.
Thinking about a home addition in Creswell? 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. Creswell is one of Lane County’s fastest-growing small cities; new subdivisions have generous setbacks, and the building department handles a steady volume of ADU and garage addition applications — owners in newer developments often add detached ADUs to lots that were graded and utility-stubbed at subdivision time.
Building a home addition in Creswell
Creswell sits 14 mi south of Eugene on 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 Creswell — 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, Creswell is known for the Coast Fork Willamette River and proximity to the Row River Valley, and we tailor every build to fit the lot, the neighborhood, and how you actually live.

Creswell home addition questions
Can Red Umbrella match my existing home’s exterior when adding an addition?
Yes — matching the existing home’s siding, roofing, trim, and window style is a standard part of every Red Umbrella addition project. Bari Swartz inspects the existing materials during the consultation and sources compatible products, including discontinued styles when necessary. The goal is an addition that looks like it was always part of the original home.
Is an ORS Chapter 87 lien notice required for my project?
Yes — Oregon law requires licensed contractors to deliver an “Information Notice to Owner About Construction Liens” before starting any improvement to residential property under ORS 87.093. This protects homeowners by disclosing that subcontractors and suppliers may have lien rights even when the general contractor is paid in full. Red Umbrella includes this notice in every contract packet.
Does building an ADU or addition increase my home’s value?
Adding an ADU or a well-designed addition generally increases a home’s resale value in the Creswell market, though the increase depends on location, finishes, and buyer demand. An ADU that generates rental income is especially appealing to buyers who can offset their mortgage with rent. Red Umbrella builds to quality standards that hold up over time and support strong appraisals.
