It is likely that it treats rooms as deployment sectors, and doesn't check for doors inside because its all still the same technical area

@Overlord: Some rooms are "special" and have an attribute that blocks them from being zoned under doors, this mod just removes that extra attribute (most of the rooms remain unchanged though).
Probably that is also used by the deployment system and sadly I don't think I can fix this, sorry!

Unsure if this is due to the mod being broken or due to Paradox, but there seems to be an issue with deployment, it sometimes takes the whole area as the room even if there are doors between them.

Using "empty room" fixes it, as shown here

At one time this didn't need to be a mod, you can still do it without a mod but it sorta fails:
while the blueprint of the door is still in place you can add the room to that square, the room will remain connected when they place the door but it will divide rooms when you reload, it's a pity it doesn't stay that way.

i dunno if you know this @4loris4 maybe it will help you, but hey, you already got the mod here! and.. subbed! cheers :) :)

@mickeyminime: Now the mod should work again for every room.
If there are still rooms that cause problems just leave another comment!

Doesn't seem to work with certain rooms.

thank you. i have been looking for this for a long time. you solved my problem with zones under doors

Exactly what I needed, thanks!

@I am not high: Thanks!

wow, it seems like you are very involved in modding and community! Thanks a lot! I really appreciate that!

@I am not high: Now everything should work!

This mod is exactly what i needed!
But i found an issue. Mod changes office room requirements, so it don't allow to put there stylish desk.

@matthewd3911: I've just updated the mod. Unfortunately I don't have the DLC so I can't test the mod myself so tell me if it works now!

second chances bakery and restaurant dont work but for some reason the meeting room does

@4loris4 ah gotcha, thanks for the reply still

@bearisland: To allow tiles with doors to be zoned I need to remove a property from the room itself, when I tried this everything still worked but the cells around the canteen said that they could not find a valid canteen (even though the prisoners still used it).
Sadly I can't do anything about this because I can either put that property back in (and remove the option to zone rooms under doors) or leave it like this where the game can't figure out if a room is correctly built in some cases like yours.

Currently messes with canteens quite a lot. I can only get a canteen working if its in its own completely separate room.

Everything seems to work, thank you very much! :D

@Pjosip: I have updated the mod, tell me if everything works!

Hey, any chance for an update?
When using the "Comfy Bed" cells don't recognize there's a bed in them!

@Nightmare Eyes: No, it only changes the vanilla rooms.

Does this work with modded rooms and doors?

@Nikzy: Updated!

Hey 4loris4 - if it's not too much to ask, could you please update this to work with the slammer update? The new update has some new room requirements that is not included in your mod :)

Just checked it and its working, thanks!

@Blackavar: Tell me if it's working now

While Peeker's comment does work, I found if I reload a map/game it breaks the rooms again and I have to do it all over again. So am glad there is a mod for it!

Noticed in my Women's Prison that Nursery couldnt be placed under doors, may need an update for some rooms. The Nursery/Family Cell are from the Women's Prison section.

guys this mod is kinda useless i found a way to place rooms under doors in vanilla!
step 1: order to place a door
step 2: before your workers build the door, zone the room
step 3: enjoy!

Awesome response time !!

@Penny Wyze: Updated

First off great mod!

There is only one thing I noticed that throws off the game for me a bit. In the 'staffroom' when you open the objects panel and begin setting up usually the defualt items are high lighted. The toilet and the serving table along with the large TV are missing. NOT a huge game breaker I' just used to being lazy about it. Would you be able to update?
Again great mod!

Never mind, there was one mod conflicting it, thanks anyway!

@Bill Nye The Nazi Spy !!!: What other mods have an higher priority? (Are on top of "Rooms under Doors"?)

canteen

@Bill Nye The Nazi Spy !!!!: With wich room?

it dosent work for me

No problem! :)

this mod actually solves a HUGE problem yet it's so simple. very under rated. seriously. thank you very much.

This mod needs more attention.

quite useful for max security prison because i can lock away the toilets lol
thanks
