How to Install Interior Mods That Let You Enter Buildings (2026)

GTA V ships with hundreds of enterable doors that lead nowhere, open into a void, or sit sealed behind a locked shell. Interior mods like Enable All Interiors and Open All Interiors wire those doors to the interiors Rockstar already built, so you can walk into apartments, mansions and gang hideouts instead of bouncing off the wall. This guide covers how to install interior mods that let you enter buildings on PC: the mod files go into a scripts folder inside your GTA V directory, they need ScriptHookV and ScriptHookVDotNet plus .NET Framework 4.8, and most of them need Online Maps turned on through a trainer. Budget about 20 minutes, and expect to read a mod page carefully before you start.

One thing to clear up first: this is PC only. PS4, PS5 and Xbox players cannot install any of these mods, and no current console version of GTA V changes that. If you searched for a PS5 install guide and landed here, that is the whole answer.

What You Need

Five things, and you cannot skip the first three. Everything else depends on which of the four main interior mods you pick.

• Your game edition. GTA V Legacy on PC or the Enhanced edition released in 2025. They need different ScriptHookVDotNet builds, and this is where most installs go wrong.
• ScriptHookV in your GTA V folder. This is the base hook every script mod needs.
• ScriptHookVDotNet in the same folder. Use the Nightly build on Legacy and the dedicated Enhanced build on Enhanced.
• .NET Framework 4.8, installed on Windows. SHVDN3 will not load without it.
• LemonUI (the LemonUI.SHVDN3 files) if the mod page lists it as a requirement. This is the single most common reason the mod silently does nothing.

Then pick a mod. They overlap and they are not the same thing, which is where most confusion starts.

Mod	Author	What it opens	Best for
Enable All Interiors	Modding community	Every interior Rockstar shipped, including the GTA Online ones	Getting the full apartment and office set working
Open All Interiors	NewTheft	Interiors present in the game files even when they were cut from the final build	Exploration and finding the hidden rooms
Enterable Interiors	jaydenwasd	Homes and buildings that never had any interior at all, lighter and more focused	Players who want enterable houses without the load
InteriorsV	Community	A third-party set of interior IPLs and collisions used alongside the others	Pairing with the above when mid-class apartments fail

The mods page for each one lists its own dependencies. Read that requirements line before you download anything, because Enable All Interiors and Enterable Interiors do not need the same files. Enterable Interiors version 1.7 and later load their IPLs and collisions on their own, which removes the old dependency on Enable All Interiors. That is the version you want.

You also need a clean, verified game installation and a trainer you trust for the Online Maps toggle. Simple Trainer is the usual choice because it exposes that toggle directly. Menyoo or Modest Menu work too, as long as you can turn Online Maps on at launch.

OpenIV is only needed if the mod ships map, collision or IPL files that go into the x64 or mods folders. Script-only mods never touch OpenIV.

Step-by-Step: How to Install Interior Mods That Let You Enter Buildings

1. Check the Game Version and Enable All Interiors Requirements

Right-click GTA V in your launcher and look at the properties panel. You are looking for two things: whether you own Legacy or Enhanced, and the current build number. Legacy builds are labelled with numbers like 1.0.3889, and a build showing 3028 tells you which update you are on.

Write that number down and hold it next to the mod page. If the mod was last updated before your game updated, expect problems. Version drift is the most reported issue in this whole niche, and it has nothing to do with your install being wrong.

2. Back Up the Files You Will Replace

Copy your existing scripts folder to a backup location outside the game directory before you add anything. If the folder does not exist yet, you are starting clean, which makes this step easy.

Two safety notes while you are here. These mods are for Story Mode, and using them in GTA Online or on a FiveM server breaks under you. Second, nothing you do here touches your Rockstar account, but it is still against the terms to use mods online, so keep it in single-player.

3. Install ScriptHookV, ScriptHookVDotNet and .NET Framework 4.8

Install .NET Framework 4.8 from Microsoft first, and let it finish. Next, copy the ScriptHookV files into your GTA V folder. That means dinput8.dll, ScriptHookV.dll and the NativeTrainer.asi file, all sitting directly in the GTA V directory, not in a subfolder.

Then do the same with ScriptHookVDotNet: ScriptHookVDotNet3.dll, ScriptHookVDotNet2.dll if present, and ScriptHookVDotNet.ini. On Legacy, grab the Nightly build from the community ScriptHookVDotNet page. On Enhanced, download the build that says Enhanced. Using the Nightly build on an Enhanced install is the version-specific mistake people hit most.

On Steam the folder usually sits under steamappscommonGrand Theft Auto V. If you use Rockstar Games Launcher or Epic, check the install location you chose, because the launcher does not always use the Steam path.

If the mod includes OpenIV files, install OpenIV and point it at your GTA V folder. It will ask you to confirm the game folder the first time, and it will prompt you to switch the mods folder into edit mode before you paste anything in.

4. Add the Interior Mod Files

Create a folder called scripts inside your GTA V directory if it is not already there. Copy the mod’s .cs and .dll files into it, along with any .ini file the download includes. That .ini is your per-interior switchboard, and it is worth opening in Notepad so you know which entries you can turn off later.

For any .ytd, .ybn, .ymap or .ytyp files, do not drop them in scripts. These go into x64 inside the mods folder, usually at modsupdateupdatex64dlcpacks or a named pack folder the mod author lists. OpenIV prompts you to click Edit mode and then No when it asks about folder ownership. Answering No is correct here.

5. Install Door, IPL, and Dependency Files

This is the step where a working install becomes a broken one. If the mod page mentions LemonUI, download it, extract the LemonUI.SHVDN3 folder and drop it into your GTA V directory so the path reads GTA VLemonUI.SHVDN3. Users who skip this end up with a mod that loads fine and does nothing.

Several of these mods also need Online Maps enabled, which loads the GTA Online map parts in Story Mode. Open the trainer, turn on Online Maps from its options panel, and keep the trainer open. Without it, mid and upper-class apartments load their door but not their floor, and you fall through into the void.

Doors come in two flavours. Marker mods drop a coloured marker at each entrance; press E to teleport in. Blip mods add a map marker you can search for instead. Some releases do both, and the colours are matched so blip colours and marker colours line up.

6. Launch the Game and Test the Building

Start Story Mode, not Online. Let the world load, open the trainer, switch Online Maps on if it is not already active, then walk to a door that does nothing in the base game. If a marker is there, press E. If you hear the door move and the interior loads with collision under your feet, the install worked.

Check the pause map for blips too. Blips present but broken interiors means the IPLs did not load. Interiors working but no blips means only the marker half of the mod loaded.

Expect a small frame-rate dip once you walk into an interior, and a bigger one if you stack several interior mods together. Loading dozens of IPLs at once is the usual cause of low FPS in dense areas like downtown Vinewood.

Common Mistakes

Almost every failure in this niche maps to one of these. Work down the table in order rather than reinstalling everything.

Symptom	Likely cause	Fix
Mod does nothing at all, no markers	LemonUI or SHVDN3 dependency missing	Install LemonUI.SHVDN3 into the GTA V folder and relaunch
Mod worked, then stopped after a game update	Version drift	Check your build number against the mod’s last-updated date and update the mod
Falls into the void when entering the door	Online Maps not enabled	Turn on Online Maps in Simple Trainer at launch
Door will not open, or blocks you on the way out	You exited an interior you did not enter through the mod	Re-enter through the entrance marker; the mod has no exit logic for foreign entries
Game freezes on load	MP map component clashing with an existing mods folder or openiv.asi	Rename your mods folder temporarily and launch with only the interior mod installed
Wrong folder, nothing loads	Files dropped into scripts instead of x64, or vice versa	Move ytd, ybn, ymap and ytyp files to the x64 folder the author lists
Crashes when a specific door opens	Two interior mods requesting the same IPL	Enable one mod at a time to find the pair that conflicts
Menu or keybind does not respond	Wrong SHVDN build for your edition	Swap Nightly for the Enhanced build, or the reverse

That conflict-isolation trick deserves repeating because it is the fastest diagnostic there is. Rename your mods folder to something else, launch the game with only the interior mod active, and the game either works or it does not. Rename the folder back afterwards.

To uninstall, delete the mod’s files from scripts and from x64, remove the .ini file, then delete LemonUI if nothing else uses it. Your backup copy restores the folder to its previous state in seconds.

Frequently Asked Questions

Start with the dependency check and the file copy, because that is where a working install comes from. Install .NET Framework 4.8 first, add ScriptHookV and the right ScriptHookVDotNet build for your edition, drop the mod files into scripts, and confirm your game build matches the mod’s last update.
