I'd like to remove a 4" raised concrete step/platform in my garage...so that this area is level with the rest of the garage floor. I had an inspector over who confirmed that I can cut and remove the section I want to, and stay within code. He pointed out that the 4" step is a separate concrete pour...it was poured separately on top of the garage floor.

Then I had a concrete guy over who said that I would have to remove the step AND garage floor in that area, and do a complete repour. Is that right? Is there no way to remove the 4" raised area without destroying/removing the original garage floor? Thanks for the help.

Here is a pic showing the step sitting on the garage floor:

And another pic down the egress, where you can see the separate pour of the raised section and the garage floor:
