Basement bar sink plumbing - HELP!

[homebuyer17]

How can this be fixed to meet Illinois code? It seems the sink sits directly above the drain and an S trap has been used.

You can check with a local inspector and see if an AAV is okay.

Thanks! I will check with the home inspector that caught the violation.
