Let's Move In Together: A Natural Way for Sims to Start a New Life
Every Simmer knows the moment. Two Sims fall in love, or two roommates decide they want a place of their own, and the story is begging for them to pack up and move on together. But The Sims 4 only offers Ask to Join Household, which pulls one Sim into the other's existing home. There is no built-in way for two Sims to leave their current households and start fresh on a new lot. That gap is exactly what Let's Move In Together fills.
What Let's Move In Together Does
This mod adds a brand-new social interaction: Ask to Move In Together. Click on another Sim during normal gameplay, make the proposal, and if it is accepted, both Sims can leave their old households behind and begin a shared life on a new lot. No interruptions, no manual trips through Manage Households, no breaking the flow of your story.
The possibilities are wide open. Move in two young adults who still live with their respective families. Let two roommates who fell in love finally get their own place. Have two brothers become roommates, or invent any scenario you can imagine. With the Guaranteed version, even sworn enemies can end up under the same roof.
How the Move In Together Interaction Works
Once the proposal is accepted, you choose which additional household members, including pets, will move with the accepting Sim, along with how many Simoleons they bring. You then make the same choices for the Sim who proposed. A summary screen appears before anything is finalized, so you can review every decision.
From there you can place the new household on a lot immediately or postpone the move. If you delay, the household waits in Manage Households until you are ready. A few sensible safeguards keep things from breaking:
- If the original household would be left completely empty, only Move In Now is offered. You can still cancel from the world map and send the household to Manage Households instead.
- If your choices would leave a child or pet behind with no Sim, the move is blocked and a notification explains why.
- If the proposal is refused, you must wait 48 Sim hours before asking that Sim again, mirroring the base game's Ask to Join Household rules.
Custom Moodlets for Every Outcome
Let's Move In Together includes 17 custom moodlets built specifically for the different outcomes of moving in together. The moodlet a Sim receives depends on their relationship with the other Sim, whether they proposed or accepted, whether they are moving out or staying behind, and, in versions where refusal is possible, whether the answer was yes or no.
That means reactions feel personal. Moving in with a partner, a close friend, or a family member can be thrilling, while sharing a home with someone they dislike may feel far less reassuring. Sims who tag along with the new household get their own moodlet, and those left behind can react positively or negatively based on their relationship with the Sim who moved out. A refused proposal gives the asking Sim a moodlet tailored to that relationship.
Choosing Your Version and Compatibility
The mod ships with three versions, and you should install only one at a time:
- Guaranteed — the other Sim always accepts. No minimum friendship is required, so even enemies can move in together.
- Can Refuse — uses the same acceptance rules as Ask to Join Household. Enough friendship plus a Fine or better mood means acceptance, and refusals cause only a small friendship loss. Romance, traits, and compatibility are ignored, with no random chance.
- Can Refuse Plus — a more detailed system where mood still matters, but relationship, certain traits, romantic compatibility, and a small element of chance all play a role. Refusals hit the relationship harder than in the regular Can Refuse version.
Let's Move In Together for The Sims 4 supports the current live version of the game, and the mod is available in English and French. Because patches can shift script behavior, always confirm compatibility with the latest update before you play. Mod conflicts are rare, but any mod that overhauls the same social interactions or household management screens deserves a second look in your Mods folder.
If you want a smoother setup, the foxygame.net launcher handles the busywork: it keeps Let's Move In Together updated automatically, so a new patch never leaves you hunting for a fresh file. That is a real convenience when you run a heavily modded save.
How to Install
Installation follows the standard The Sims 4 modding routine. First, download Let's Move In Together from its official page and extract the ZIP archive. Remember that the archive contains three versions, so keep only the one you want and delete the others. Drop the remaining package file into your Mods folder, typically found at Documents > Electronic Arts > The Sims 4 > Mods. Make sure mods and script mods are enabled in Game Options, then restart the game. If you are updating from an older build, remove the previous file first to avoid duplicates.
A Known Issue Worth Noting
There is one documented bug to keep in mind: Sims can instantly leave their dynasty when they are merged into the new household after using the Move In Together interaction. The creator is actively working on a fix, so check the mod's status page before starting a legacy save you care about.
Final Thoughts
Let's Move In Together solves a problem that has quietly annoyed Simmers for years. It turns a clunky, menu-driven process into a natural story beat, complete with meaningful emotional reactions through its moodlet system. Whether you are staging a romantic first apartment or a chaotic enemy roommate experiment, this mod gives your Sims the freedom to choose their own next chapter.
