Floor drain in existing garage

[corner27]

I have a 22x30 detached garage. It was unheated until now. The problem I'm facing is there is no floor drain, so all the snow that melts off the vehicles just sits of the floor that is not sloped very good. All the water is pooling up against the wall.
My question is, how do I go about installing a floor drain?
Can I chip away a 1 ft diameter hole, use a post hole digger to dig down, fill it with cruched rock, then put a drain over and repour cement up to the drain to cover the hole I chipped away?
Since the floor is not sloped very well, can I cut grooves sloped towards the center of the floor where I will be putting the drain? or will that be prone to chipping.

Yes and no.

Can you simply make a hole and put a cover over it as a drain? Yes.

Is it legal? Does it satisfy local codes? Is it even allowed?

Most of the time, drains in a garage are a no go for us.

Where I am from, it is perfectly legal to to have a floor drain in the garage. From the 2 new builds I know about, they had a 6" pipe going into the ground with crushed rock in it.

If thats the case, then you could just put a hole in there and use squeegee to move the water in the hold since you would not have any slope in the floor to direct the water.
