Tim O'Hara

Certified Master Inspector



Home inspection is an occupation that requires significant knowledge in all building trades. Courses teach the basics but experience and learning from experience takes time – and a lot of it. I have been inspecting for 30 years and have performed an estimated 5,000 home inspections in the Yankton, Vermillion and surrounding markets. CSI Home Inspections is THE MOST EXPERIENCED inspection company in the area. I was trained by my father, Pat O’Hara, who was one of 4 inspectors in South Dakota when he began and the only one in Yankton and Vermillion, at that time. In fact, my father and I assisted in writing the test inspectors now take to be licensed in South Dakota. In addition, I have 20 years of experience in the construction industry and a degree in Construction Technology which included studies dedicated to structural engineering.


CSI Home Inspections offers whole home inspection, pest inspection and radon testing. I am also a licensed appraiser and listed on the FHA roster. This is a benefit to my customers who may be getting an FHA, VA or rural development loan. I know what repairs may be called out by an appraiser and can help you get a jump on those repairs prior to the appraiser coming.

If you are considering selling your home, I also offer pre-listing inspections. This smooths out the selling process by minimizing defects and helps your home “show” in a more positive light. I will provide a full report and if any repairs are completed I will return to re-inspect and provide a revised report for you to have available for your potential buyers. The reinspection and revised report are included at no additional fee. 


CSI Inspections is licensed in home inspection, thermal imagery, radon testing, pest inspection and I carry  Errors and Omissions insurance for your protection.

You will have a complete report the same day I inspect your property.

I encourage my customers to meet with me at the property at the completion of the inspection to view my findings in person. If it is not possible to meet and review a preliminary report you will still get a full report the same day and be able to contact me as often as you like with questions.

Customer Reviews

“We recently had the pleasure of working with Tim as a result of putting my parent’s home up for sale. It was suggested to us that a pre-inspection of the home might help expedite the sales process. Tim was not only professional and quick to respond but was very thorough and just a nice guy. His report was precise, informative and also provided helpful advice. In addition, he returned to the home after we made corrections, did a reassessment and provided us with an amended/updated report. We have been very appreciative of his assistance and would not hesitate to refer others to his expertise.”

Thank you so much for completing our home inspection. We appreciate the time and attention that you took while doing the inspection as well as the extra time you took to speak with us to explain your findings. We are very fortunate to have  found an inspector who takes pride in their work and has the customers best interest in mind. Again, thank you.”

"We actually got to work with Tim twice in one year on two different properties, and both times he was wonderful. Very thorough and professional. He was honest, down to earth and the prices were very reasonable! We were really pleased with our experiences with CSI Inspections and would highly recommend to anyone purchasing a home."
