Is this OCD, if not... what?

sure it is. Making lots and lots of lists is one of your rituals, so is cleaning your house spotless and to a point you consider perfect. The thing is though that a certain level/ amount of this behaviour will actually help you through. Seriously who wants to be next to a person who isn't clean? Or visit a house that's nasty? Do what you feel is best. If it's bugging you talk to a prof. and see what they can do for you.
