Frequently Answered Questions
How much does it cost to build a custom home in Medford, Oregon?
Building a custom home in Medford typically costs between $260 and $420+ per square foot, depending on design, finishes, site conditions, and lot prep; hillside and view lots in east Medford 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 Medford?
Yes. ADUs in Medford require permits through the City of Medford 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 in the east Medford hills or on a hillside lot?
Yes. We build ground-up custom and view homes on hillside and sloped lots throughout east Medford and the Rogue Valley, handling the site evaluation, foundation engineering, access, and Jackson County permitting that hillside 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 suited to Southern Oregon's hot, dry climate?
Absolutely. We build for the Rogue Valley’s hot summers and mild winters — with proper insulation, energy-efficient systems, and materials suited to Southern Oregon’s climate.
