Plumbing codes change from state to state. What you want to do in a violation of code in Ohio, Kentucky, and Indiana. In these three states you have to use gravity and a three inch pipe. You may only use a grinder pump to lift sewage from the basement. Even then the toilet will drain by 3 inch pipe into as pit that contains the grinder pump.

Are up-flush units not legal in those states?

You can use them only when it is required by elevation. Usually remodels, on new construction it is preferable to install a pit for ease of maintenance. The up flushes incorporate a tank above the floor. So when you go to fix the grinder pump you have a full tank of shit sitting in your bathroom. A pit you can install any place in your basement where it is convenient.

Yeah, I've installed a few of them in basement renovations. We've always urged folks to get the extension pipe so that the tank can reside on the other side of a wall behind the toilet.
