Home is one of the final floors in The Binding of Isaac, alongside Chest, the Dark Room, The Void, and Corpse. It was added in The Binding of Isaac: Repentance, and acts as Isaac's house in his imagination.

Home can only be accessed after picking up Dad's Note and going through the ascent. The bosses of the floor are always Dogma, followed by The Beast.

Layout

The Home floor has no enemies, and is completely empty. Similar to ??? and the Greed mode floors, its layout is always the same. Home features Isaac's room, two corridors, a room with a pickup, the living room, and Mom's room.

Isaac's room is where Isaac spawns upon entering the stage. It contains a bed in the upper left corner and a carpet in the center, like a regular Bedroom, as well as a golden chest. Isaac can sleep in his bed to recover provided he's not at full health, or to add three Soul Hearts provided he has no Red Heart containers. Triggering an explosion on the carpet will cause it to be damaged, but reveal nothing underneath.

A single door in the bottom wall leads to the narrow right corridor. Through a door in the upper side of the right wall is a small room that contains a random pickup or, rarely, an item. Further down in the left wall, there is another door leading to the house's living room.

The living room is double-sized and extends vertically downwards from the entrances at either side. It contains a large turned-off TV, placed against its northern wall, and a couch further south, as well as a red carpet located between them with a massive picture of a cross with wings. A door in the upper left side leads to another narrow corridor, which Isaac can walk north to reach Mom's room.

Mom's room contains a unique chest, a carpet, a dressing table, and Mom's bed — all of them larger than similar items found throughout the game. When the chest is opened for the first time, it will contain the Red Key, which will be permanently unlocked. In subsequent playthroughs, it draws from its own item pool of Mom related items; the Red Key can still be found, but more rarely. The carpet and the dressing table in this room cannot be interacted with.

Sleeping in Mom's bed will cause Isaac to have a nightmare, showing the loading screen with no floor icons. In the dream, Isaac is sitting next to his mother as she watches TV. Isaac's distorted face then appears on the TV screen, as the noise of static begins to increase in volume.

After a flash of static briefly covering the entire screen, Isaac wakes up again, presumably at night since Home is considerably darker. At this point, when exiting Mom's room and walking down the left corridor, a grey light can be seen through the bottom-right door. The source of this light is the TV in the living room, which is turned on but only emits static. Stepping on the cross in the living room's carpet will begin the battle against Home's boss, Dogma.

Upon beating Dogma, a cutscene will play — then the fight with The Beast will start.

Hidden closet

In the hallway leading to Mom's bedroom, using either the Red Key, Cracked Key, or Soul of Cain will open up a hidden room. This is hinted by the existence of the closet on the other side of the map, by Isaac's bedroom. There is also a barely visible glowing red outline for the hidden door when the Red Key or Cracked Key has been picked up. The closet is also the place Isaac is thrown into in ending 21.

Inside is the tainted version of the character currently being played, laying on the floor, crying. Touching them will unlock that character, which can be selected from their own menu and has their own unique mechanics and unlocks. Each playable character has a tainted version that can be unlocked this way. If the player changes the character (for example dying with Missing Poster and respawning as The Lost) and re-enters the Hidden Closet, the crying baby will not change to the corresponding character, and will stay as the first character it turned into. This means the player cannot unlock two Tainted Characters in the same run. In true co-op, the character in the closet will be the tainted version of player one's character.

If the tainted version of a character has already been unlocked, or a tainted character is being played, the closet will contain Inner Child. If Inner Child has not been unlocked, it will contain a Shopkeeper instead.

The method for obtaining a Cracked Key during the ascent is described on their respective pages, but Red Key can also be obtained from Curse Rooms (if unlocked) or by using Pandora's Box on the Home floor.

Trivia

• The fact that there isn't a trap door underneath the rug in Isaac's bedroom hints towards the Final Ending, as the game is kicked off with Isaac finding and using a trap door underneath his rug in order to escape his mother and using it to reach The Basement.
• The Bible and Mom's Purse can be seen on top of her dresser in her room. Mom's Lipstick, Mom's Perfume, and Mom's Eyeshadow can be seen atop a dresser beneath her mirror. Various pills can be seen in the drawers reaching from her bed.
• The unique chest in Mom's room resembles a much larger version of Mom's Box.
• The drawings seen in Isaac's room reference the events of Ending 20.
• The closet created by using the Red Key resembles the one featured in the Official Art for Repentance and is most likely shown in Ending 21.
• Normally unseen, there is a crack on the door to Isaac's room referencing the events of the game's introduction cutscene where Isaac peeks through and sees his mom approaching with a knife. It can be seen by using Everything Jar and getting it to close the room's doors.
• Including the hidden room, Home's layout resembles a heart. This may be a reference to the phrase 'Home is where the heart is'.

Bugs

Bug!	If the player resets the level with Forget Me Now or any other item, when they attempt to lay in the bed, the game will glitch out. Night will not fall and the player will be unable to interact with the bed or fight the boss. This results in a softlock. This can be fixed if you summon Dogma with the console in the fight room.

Bug!	If the game crashes or the player closes it during Dogma's death cutscene, when the player returns to this run, the game will not restart Dogma's fight. This results in a softlock, since there is no way to manually start the final cutscene. The player is stuck in Home, and Dogma's fight room replaces the living room.

Bug!	If two or more players run the game with different characters and resets the level with Forget Me Now or any other item after one of them unlocked a tainted character in the closet, opening it again with other character will contain Inner Child. If Inner Child has not been unlocked, it will contain a Shopkeeper instead.
