Do I have to create a subfloor over my cement floor. I have been in this house for 10 years with never an issue with my basement floor. My preference is to tile.
Installing a subfloor is a good idea just in case there is a future issue with water coming into the home but from my experience most home owners don't invest in this but I've never had a customer where water became an issue after flooring installation
sub floor is not required by code but is good incase water somehow gets into the basement.
odds are it wont but there are the exeption
i installed a floor and my customer had refused subfloor and 2 weeks later called me wanting it re done because of a fluke heavy rain storm and a faulty sump pump
I concur. If the concrete is in excellent shape with no further possibility of settling then yes I would install tiles on top. You may wish to consider a crack isolation membrane to ensure no movement in the concrete will impact your tile installation.

ken, as stated a sub floor is not essential, but if you want to increase the warmth of your basement year round, I would suggest installing in-floor heating under your tiles first. If you are going with laminate, engineered wood or carpet, a sub floor is again a good option to help increase the warmth of your basement. The reason for this is because moisture from the ground will "radiate" through you concrete floor and you will feel this.
Thank you all for your suggestions. Sounds like a subfloor is the way to go and it will give me several flooring options other than tile. I appreciate your expertise
