Correct plumbing stackable washer/dryer

Hello! I have recently began planning to install stackable waher and dryer in my upstairs kitchen so my downstairs tennant will have there own. I am not sure of the guidelines/codes I am to follow as far as distances where the incoming hot and cold fixtures should be on the wall behind unit and where the elecrical outlet should be in relation to plumbing shutoffs and floor.I have an existing dryer vent in the floor left corner. will that be ok there?
could you please help?
thanks!

Are you installing a drain or just water and electric?

Given your questions, you should have professionals to the installation so it is done correctly. If the locations of the water, drain, electrical, and vent are critical to that combination, the manufacturer will have a "rough in" diagram showing where to put them.
