Here's mine:
I have to have my phone in my right pocket and my wallet in my left, or nothing in either. I can't be unbalanced.
I have to put cutlery in the drying rack with spoons together, forks together, and knifes together in their own separate compartments . Knifes left, forks middle and spoons right. Recently I purchased a new draining rack and it only has two compartments for cutlery, which troubles me.
Plates on the drying rack must go from largest to smallest. When putting the plates away the blue ones always have to be below the cream ones.
When hanging clothes out, the pegs must be the same colour as each other per item of clothing, and preferably the same colour as the item of clothing being pegged.
When folding towels up to hang the labels cannot be visible.
So, share your OCDs
