Another picture for ya...this is part of my 3/4 bath. That is a vanity drain on left and a shower drain on the right (toilet drain not shown in this pic). Above the floor the vanity drain has a dry vent. The shower drain drops about 30" to the trap. I poured a cup of water in the shower pan and I think my neighbor could hear the water dropping into the trap from across the street. This is going to drive me nuts. What should be done here?

The shower needs a vent. Additionally the max drop allowable from the shower drain to the trap is 24" (UPC)

No reason as far as I can see that he couldn't have mounted that trap closer to the floor above so as not to give you a loud dripping noise as the drops accelerate to warp speed before hitting the water in the trap. "The trap shall be placed as close as possible to the fixture outlet. The vertical distance from the fixture outlet to the trap weir shall not be more than 24"."

Can San-Tee's be on their back for venting (not drain?

Not in the more recent UPC code books out here on the West Coast.

On the 24" vertical. I saw a tub hooked up with a long tail piece like that. When the tub drained, it would siphon the p-trap dry. A shorter distance prevents that.
And yes, where is the vent for the shower on that picture?
