Open All Interiors — Explore Every Building in GTA 5 (2026)

Open All Interiors — Explore Every Building in GTA 5

The Open All Interiors mod unlocks dozens of hidden and inaccessible building interiors throughout Los Santos and Blaine County. While Rockstar created many detailed interior spaces for GTA 5's story missions, most remain locked after completion. This essential mod opens every single one of them for free exploration, dramatically expanding the explorable space in Los Santos and revealing hidden gems you never knew existed.

Unlocked Story Mission Locations

Revisit iconic locations from GTA 5's story mode that are normally locked after their respective missions. Explore the LifeInvader office where you completed a memorable assassination, walk through the Humane Labs research facility, and revisit the FIB and IAA headquarters. The Bahama Mamas nightclub, Tequi-la-la bar, and numerous other mission-specific locations are all permanently accessible, letting you appreciate the incredible detail Rockstar put into environments you may have rushed through during gameplay.

Hidden Interior Discoveries

Beyond mission locations, this mod reveals interiors that most players have never seen. Fully furnished apartments throughout the city, detailed hospital emergency rooms and operating theaters, complete jail interiors at the Bolingbroke Penitentiary, and staff areas of businesses like Cluckin' Bell and Burger Shot. Many of these interiors were created during development but never made accessible to players, making each discovery feel like finding hidden content.

Teleportation and Navigation

The mod includes a convenient teleportation menu that lets you jump directly to any unlocked interior. Each location is categorized by area and type — residential, commercial, government, and industrial — making it easy to find specific buildings. Map markers indicate accessible interiors on the world map, so you can also travel to them naturally while exploring the city on foot or by vehicle.

Perfect for Content Creation

For machinima creators, photographers, and content producers, Open All Interiors provides an incredible library of ready-made sets. Stage scenes in courtrooms, hospitals, offices, restaurants, and dozens of other professionally designed interior spaces. The mod is perfect for creating cinematic content with varied indoor environments that would otherwise require custom MLO installations.

Installation and Compatibility

Open All Interiors installs as a simple script mod requiring Script Hook V and a compatible .NET framework. The mod has virtually zero performance impact since it only loads interiors when you enter them. It is compatible with most other mods including visual enhancements, vehicle packs, and gameplay modifications, making it a must-have addition to any modded GTA 5 setup.
