Contractor installed this convoluted p-trap + elbow for the washer, and I’m not sure if it’s up to code. Can you confirm and more importantly explain why or why not it’s compliant?

I’ve got a similar situation to your rental for my basement (the main floor drains separately). There’s a macerator/pump combo in an 8ish gallon tank in a pit cut through the foundation (lined with concrete) that elevates to the main drain outside the house. The pump failed a couple years ago and was not fun to deal with. Luckily it was exclusively laundry that day. Everything connected to it is vented.
When we get pushed to connect to sewer (one way or another), my plan is to get a bit silly and connect at the lowest level so we can avoid the pump for the future.
When you do get that connection … go the extra step and install a ‘backwater prevention valve’ … it’s a giant one way valve that is attached to the main drain line as it leaves the house.
It allows water to always easily flow out but if it ever happens that water back flows into your house for some reason … the valve will stop any flow from entering your house.
I’ve always planned to get one but my situation is too difficult to install one.
That does seem pretty obligatory. We have the same thing on our irrigation (don’t want irrigation water backflowing in to the drinking water, and also it’s required).
We are at the top of a hill and everything flows down from us to the entire neighborhood, so that is another good check on the issue.
