Frequently Answered Questions
How much does it cost to build a custom home in Roseburg, Oregon?
Building a custom home in Roseburg typically costs between $250 and $410+ per square foot, depending on design, finishes, site conditions, and lot prep — hillside and view lots often run higher due to foundation and access work. A fixed-bid estimate from Kempf Construction gives you an exact price before construction begins.
Do I need a permit to build an ADU in Roseburg?
Yes. ADUs in Roseburg require permits through the City of Roseburg and must comply with Oregon’s statewide ADU rules covering size, setbacks, and parking. As a licensed contractor, we handle the entire permitting process for you.
Can you build a view home on a valley hillside or acreage lot?
Yes. We build ground-up custom and view homes on hillside, sloped, and acreage lots throughout the Roseburg area and Umpqua Valley, handling the site evaluation, foundation engineering, access, and Douglas County permitting that these builds require, and managing construction start to finish.
What's the difference between a general contractor and a home builder?
A general contractor manages and coordinates all aspects of a construction project — permits, subcontractors, scheduling, and inspections — for remodels, additions, and new builds alike, while “home builder” usually refers specifically to new-home construction. Kempf Construction does both.
Do you build homes and ADUs on acreage in the Umpqua wine country?
Absolutely. The acreage and rural-residential lots around Roseburg are ideal for custom homes, detached ADUs, shops, and additions. We handle design, permitting, and construction start to finish.
