My Room My Stuff
Have you ever watched your Sim child walk past their own bedroom bookshelf, only to grab a book from a sibling's room across the house? Or seen an adult Sim trek to a distant toilet when a perfectly good ensuite is right next to their bed? This is the classic "no sense of personal space" problem in The Sims 4. Sims treat every object as communal property, creating constant, low-level chaos that quietly ruins immersion in busy households. The My Room My Stuff mod by deadlystingnyc fixes this by giving every household Sim a genuine sense of "this belongs to me."
Why Your Sims Need My Room My Stuff for The Sims 4
In the base game, Sims have no concept of personal belongings. They gravitate toward whatever object is nearest or available, with no regard for whose room they are walking into or whose things they are using. This mod changes that behavior by assigning furniture to the Sim or Sims who sleep nearby. It's a simple concept with a profound impact on how your household functions.
How the Mod Works
Assign a bed to a Sim the normal way—click the bed, then "Assign Bed To"—and the mod treats that bedroom as theirs. Everything in it becomes their stuff: the dresser, the mirror, the desk, the bookshelf. A walk-in closet or ensuite opening off the bedroom counts as part of it. Sims will cross the house to use their own things rather than settle for whatever is nearest, and they will stay out of other people's bedrooms.
Both sides of a double bed count, so a couple shares a room and everything in it. A room with two assigned beds belongs to both Sims. Bathrooms follow a preference order: a Sim uses their own ensuite first, then a bathroom their bedroom shares with another (a Jack-and-Jill between two children's rooms belongs to both), then any bathroom nobody has claimed. Someone else's bathroom is a last resort—if the need is urgent enough, or there is genuinely nowhere else to go, they will use it without hesitating.
What Always Belongs to Everyone
Not everything is restricted. The mod is smart about shared spaces:
- Laundry and kitchen equipment, wherever it stands
- Fridges, ovens, and dishwashers
- Bins and plumbing in kitchens, utility rooms, and hallways
Also, anything you click manually is never blocked—the mod only influences autonomous choices. Caring for someone (tucking in a child, comforting a toddler, feeding an infant, playing with a pet) targets the Sim or pet, not the furniture. Service Sims like maids, nannies, repair technicians, gardeners, butlers, and delivery Sims work wherever the job takes them.
Configuration Options
Optional configuration is available. Place mrms_config.cfg next to the .ts4script in your Mods folder to customize behavior. The file is re-read every time you load a lot, so changes take effect as soon as you travel or reload. Key settings include owner_multiplier (how strongly a Sim prefers their own room's things), intruder_multiplier (how strongly they avoid someone else's), routing_enabled (whether Sims walk around rooms that are not theirs), and more.
Compatibility and Installation
My Room My Stuff for The Sims 4 requires only the base game—no packs needed. It is tested and compatible with the August 25th, 2026 Patch (PC/Mac: 1.127.41). The mod works alongside "Get Up and Go," picking a bathroom for the morning routine itself rather than leaving it to autonomy. Neither mod requires the other, and neither interferes with the other. It has no tuning overrides, though it may conflict with other mods that modify the same autonomy scoring methods.
To install, download My Room My Stuff, unzip the folder, and drop it into your Mods folder at Documents/Electronic Arts/The Sims 4/Mods/. In-game, go to Game Options → Other and make sure Script Mods are enabled. If you're looking for a seamless experience, the foxygame.net launcher offers a one-click install for My Room My Stuff, automatically handling version compatibility checks so you always run the correct build for your game patch.
How to Install and Start Using It
Knowing how to install is straightforward, but here's a quick recap. After downloading, ensure the .ts4script file is not buried too deep in subfolders—one or two levels is fine. Launch the game, enable script mods if prompted, and restart. Your Sims will immediately begin respecting room boundaries. For players managing multiple mods, the foxygame.net launcher also maintains an add-on catalog where My Room My Stuff can be updated automatically, saving you from manually tracking patch notes.
Routing and Realism
Routing is handled as a preference, not a wall. Sims walk around bedrooms that are not theirs when there is another way round, but if the only route to somewhere runs through a bedroom, they still take it. The routing_cost setting (default 500.0) determines how far out of their way they will go to avoid a room. This keeps the behavior realistic without trapping Sims in impossible situations.
In conclusion, My Room My Stuff transforms chaotic, boundary-less households into homes where every Sim has a place to call their own. It reduces the constant low-level frustration of watching Sims invade each other's spaces, and it makes residential lots feel like real homes. Whether you're raising a large family or running a multi-generational mansion, this mod is an essential quality-of-life improvement.
