I have slight OCD whenever I lock my car, I always press the lock button on my fob at least twice and still check to see our car is really locked. I think I do this because my last car was broken into.
When I’m in the car with the radio on and someone mispronounces a word, I correct the radio. Out loud.
Wallet, keys, knife. I tap my pockets when ever I move from one place to another.
Makes airline travel a bit of a problem because I only get two out of three.
My clothes closet is arranged by clothing type, length, and color. So, white sleeveless, green sleeveless, black sleeveless; white short-sleeve, green short-sleeve, black short-sleeve. Etc.
My books are arranged by type, then by author surname.
ETA: I used to be extremely OCD, but I currently take a SNRI as part of pain management, and it seems to have also stopped some of the OCD tendencies.
I keep my shirts folded so that they stand vertically in the drawer, similarly to the KonMarie method:
Folding a shirt so that it will stand vertically in a drawer
This allows me to keep all of my T-shirts in the same drawer as my many long-sleeved winter shirts with room to spare.
I am also compulsive about checking the pockets of my travel vest while on vacation. I invested in a not-cheap travel vest years ago, and it is amazing. Special pocket for phone, passport, wallet. I do this little patting routine as I’m walking around to make sure everything is present and correct.
My kitchen shelves look a bit OCD - I buy ingredients in bulk and store them in Mason jars (repurposed pasta sauce jars). I’ve been doing this since college. Beans, lentils, quinoa, etc. all in neatly arranged clear jars.
I used to do that but, I don’t know if you have noticed, the frequency of mispronunciations in radio newscasts has increased markedly over the past few years, so much so that I would probably require mandibular surgery if I’d kept it up, not to mention the multiple hospital stays after stroking out caused by the ruptured blood vessels in my brain because of my constant screaming at the radio.
Seriously, do newscasters even go to college anymore?
We have a hallway outside of my bedroom. At one end of the hallway is a light switch to turn the hall light on or off and at the other, opposite end, there is another light switch that does the same thing.
However these two light switches are connected in a way that one will turn on the light and then: 1. Either the same one will turn it off again (duh) OR 2. The other one will turn it off again…which means that it requires you to flip the switch UP to turn it off.
THIS means (try to stay with me here, folks) that both switches would be up at this point, although the hall light would be off and to turn it on again, you’d have to switch one of the switches down, then, when you’re done with the light, you have your choice again: Either flip the other one down so that they’re both down OR flip the first switch upward again so that they’re both up and the light is off.
…
NOW that I’ve gotten all of that out of the way: For some reason, it bothers me whenever both lights switches are up and yet the light is off. I wouldn’t consider myself having huge OCD or being that way about much, but whenever I KNOW it’s like this (or pass by and see it like this), it just feels…extremely unnatural to me. I HAVE to flip that switch down, turn the light on, and then run to the other side and flip that one down too, resulting in the light only being off when both are down.
So yeah, if anything about me is OCD, this is. 
Right now the light is off due to both switches being down, not up, so that means that–for now–all is right with the world.
Oceans may rise, asteroids may fall, Donald Trump may become president…but dammit, those switches are down and the light is off, like it should be, Both switches being down and the light being on OR/AND both switches being up and the light being off is…an…AN ABOMINATION!
All clocks have to be exactly in step. Which is why I finally disabled the useless digital clocks in the range and microwave.
And yeah, light switches as above. We have several multi-switch setups and I will walk around a room putting all the switches in coordinated positions.
Dupe post; network must be a little OCD today.
One of my t-shirts says, “I have CDO. It’s like OCD, but the letters are in alphabetical order, as they should be.”
Seriously, though, I know there’s a line between OCD and everything else. I have danced on both sides of that line. I no longer clean for a living, so I’m not so tempted to go there.
I have OC/DC, which is an overwhelming urge to correct heavy metal lyrics. Currently I’m up to “Who Made Whom?”.
I have OCD bad enough that I’ve been prescribed medication for it.
I will lock and relock doors sometimes, check my car to make sure the windows are rolled up (don’t want rain in it.)
There was one time when a dehumidifier possibly began leaking refrigerant, and the idea of that bothered me enough that I bought a handheld Freon detector and used it to check my house for possible refrigerant gas leaks.
If a spot on the carpet is dirty, I will avoid stepping on it with bare feet until or unless it’s cleaned.
I take very long showers at times.
Things that were installed crooked or out of sequence bug me. Facebook is full of the “you had one job!” examples of tile done poorly, and I used to have a dentist that may have had an inner ear disorder as every picture in their waiting room was tilted the same amount off level.
You’d go seriously crazy in my house Idle
My kitchen light has three switches.
The only thing I get a little OCD about is paying bills.
I have to pay them online, and after I pay them I log out of the site and log back in to make sure it has been credited. Then I check my bank balance to make sure the money has been taken out and applied in the right place.
The places that have a bit of delay in the steps drive me crazy until I can see that everything is processed correctly.
I once dated a woman with OCD so bad it eventually broke us up. Just like it did with her previous boyfriends. When I started dating her she told me that if I ever wanted to break up, just tell her. All the others just left in the night and never came back. I became one of those.
I vowed never to be like that. I think the only quirk I have is that I don’t like to see two shoes setting beside each other the “wrong way”, i.e., the left and right reversed.

Mine is deliberate. I check, using my left hand, that my front door is locked before I leave my place. I started doing it because I would leave for work, get 2 minutes away and then not be able to recall locking the door. So I would go back, climb the stairs, find out (every bloody time) that I had, while distracted by thought, locked the door and then go about my day.
Now when I have the flash thought about whether I locked the door or not I can remember doing it.
A few of the above mentioned ones, but my big one is forgetting if I closed my garage door. And just to be clear, it’s that I don’t remember if I closed it, not that I’m going back 10 times to check on it. I’ll drive away and nearly always circle back around my block to make sure it’s closed or double check before I go to bed to make sure it’s closed. For the first couple years of my daughter’s life I’m sure she was convinced that driving around the block was just part of leaving the subdivision (I wonder if the neighbors ever noticed it). There were times when I even drove back from several miles away. In all those times, I think the garage door was maybe open once. Oh, and to make it worse, if I doubled back past my house and decided to run in and grab something, then I’d end up doing the whole thing over again.
Anyways, the perfect solution to all this…I put a webcam in my garage. Now, when I’m a mile and a half away I can just pull it up on my phone and say ‘yup, it’s closed’, and I do that nearly every single day.
But, as I remind people, I don’t have OCD, I just have a terrible memory and if leave my garage door open anyone can just walk right into my house.
And as for taping all my pockets to make sure I have everything (even if I do it a bunch of times as I walk through the store) or wanting my 3 way switches in the ‘right’ place, those don’t exactly impact my life in any great way.
You might like something like Quicken, or even just an old fashioned Check Register. As you make a payment (of any kind) from your checking account, you record it. Every few days you check your online bank balance to see what’s cleared and check those off in your register. Anything not checked off after a reasonable amount of time needs to be investigated. Also, I always copy and paste the confirmation number over to Quicken. I’ve never, once, ever needed a confirmation number for anything like that, but just the fact that I have it there in the memo tells me I probably did, in fact, make the payment and it just hasn’t gone through yet. If I don’t feel like going to that company’s website, logging in and finding the place to see if I actually did make the payment, I know I’m probably safe to wait another day or two and check again.
I press the lock button on my car key fob twice before leaving the vehicle.
I tap my pocket to check I have my home keys with me.
I re-check the kitchen stove when cooking to see I have the right plates turned on.
I do these things because I have left my car unlocked thinking I locked it, I have slammed the door shut only to realize I left my keys in the other pants’ pocket, and I have almost burned the kitchen by turning on the wrong stove plate. I’m not OCD, I’m doing what I need to do.
So does my mother’s hallway and she’s the only one who will not keep them coordinated (the one at the entrance may be off-kilter with the other two, but only if the light is on for mere seconds while we open the door). It’s not OCD, it’s The Way It Must Be.
I’ll mention three. Two that I think are nutty and one with practical benefits.
(1) I use wood (not drywall) screws for smaller carpentry projects that require disassembly for maintenance or adjustment. When I disassemble them I always make sure to put the screws back in the same hole they came out of. I often make temporary screw holders for the screws to ensure they go back where they came from. Even I think this is nutty but I can’t stop doing it.
(2) Like most homeowners I have a few utility buckets of various sizes. If I use one and it needs rinsing out I place it upside down to dry over a specific post near my trash cans. There are other posts around the property but I only use the “bucket post.”
(3) My pickup truck is 30 years old and I live in a rural area. I rarely lock it. But when I do I have to be holding my car keys visibly in my hand before I close the locked door.
Honorable mention to Idle Thoughts light switch dilemma. I do that as well, but I never thought of it as OCD-like behavior.
