About Kempf Construction LLC

We deliver additions and expansions that match your home’s structure, style, and budget. From feasibility and permits to framing, finishes, and final inspection, our team manages every detail with clear communication and clean execution.

We coordinate with designers and architects, expertly handle all necessary City of Eugene and Lane County permitting requirements, and meticulously maintain a safe and tidy jobsite throughout the entire construction process.

Every addition begins with a clear plan and a realistic budget that accounts for all potential variables. We conduct a thorough evaluation of the structure, utilities, and site access, then meticulously sequence the work to minimize disruption to your daily routine and lifestyle. Our dedicated team coordinates engineering efforts, inspections, and material lead times with precision, ensuring you’re never left guessing about what comes next in the process.

"Thank you so much to Danny, Ashley, Oscar, Josh, and everyone at Kempf. They took over a project for someone else that went bankrupt in these challenging times and were so helpful, professional, and we were truly blessed to have them work on our house. If I ever need anything this day forward, I know who I am calling. Thank You again; you transformed our house into looking brand new."

"I was given these guys contact info from an engineer that recommended some repairs on our home. I left them a couple voicemails and an email but never got a response. I know they are probably busy, but i would have appreciated a call telling me they aren't taking on new work."
