I'm considering adding a 2nd floor laundry to an existing bathroom and want to make sure it's feasible. The washer will be located Inline with an existing toilet, approximately 4' away. The washer would share joist space with the toilet, so running the 2" drain line will be relatively easy - but I'm concerned about tying them together. The toilet has a 2' closetbend before it connects to a 3" vertical drain line running all the way to the basement. If I understand things correctly I CANNOT tie the laundry line into the toilet drainline before the closetbend, but must tie into the 3" vertical drain line after the toilet connects. Is this correct?

you cant just tie in the washer drain anywhere on the toilet drain line...it all depends on how the bath is vented...if its vented together then you have to put your 3x2Y after the sink and tub/shower
id also recommend a Mustee 99 drain pan....your washer will leak eventually and it will save the drywall repair
i dont think this is a homeowner project...hire a plumber

The 3" line doesn't run above the toilet. After a 2' horizontal run, the toilet ties directly into the 3" drain which turns down into the basement. Is it allowable to use a 3" 90 elbow with a side inlet? Basically replace the current 90" elbow from the toilet flange with this, allowing the 2" washer drain line to enter past the toilet.

In many, if not most, cases, HOW you do it is more important than WHAT you do. WIthout seeing HOW you intend to run the washer piping and what the connection to the 3" line looks like, we cannot tell you if it is proper, or even the best way.

if the toilet run is 2 Feet long and then drops straight to the basement, it is not vented properly. if you put a side inlet 90 and run the washer drain into the 2" side inlet and properly vent that 2" drain, you'll be way ahead of the game.
you will have a sort of wet vent but you may run the risk of syphoning the toilet when the washer drains??
