What Does Barricading Your Apartment Do in 30 Floors Up?
Barricading your apartment in 30 Floors Up keeps the hallway zombies out and protects you. Here's what it does and how it fits your 100-day survival routine.
Quick answer
Barricading your apartment in 30 Floors Up keeps the zombies that roam the hallways out of your home and protects you while you are inside.
- Barricade your own apartment during the 100-day survival run: it is one of your three core day-to-day survival activities, alongside scavenging food and storing water.
- Treat it as recurring survival work, not a one-time setup.
- A barricade does not replace staying quiet: zombies fill the hallways and are drawn to noise while you move through them.

What barricading your apartment does
30 Floors Up strands you in an apartment building 30 floors above a zombie apocalypse, and your goal is to last 100 days. The hallways between the apartments are full of zombies, and your own apartment is the space you control. Barricading it is the measure that keeps those hallway zombies out — the game's own summary pairs the activity directly with the threat: scavenge food, store water, and barricade your apartment while you stay quiet as zombies fill the hallways.
In practice, that gives the barricade a clear job: it stands between you and everything moving in the corridors. The game's guide describes it in exactly those terms — barricade your apartment to keep the hallway zombies out, and barricade it to protect yourself. If you are deciding whether the activity matters, that is the whole answer: it is your apartment's defense against the zombies on the other side of your door.
How barricading fits your day-to-day routine
The game presents barricading as routine survival work rather than a single task you complete once. Your day-to-day work is gathering food, storing water, and blocking off your apartment — and the suggested opening moves for a new run put the pieces together in order:
- Scavenge the building for food and water so you have supplies from the start.
- Barricade your apartment to keep the hallway zombies out.
- Stay quiet while moving through the hallways, since zombies are drawn to noise.
The order is useful for seeing what each activity covers. Scavenging and water storage keep your supplies up, because being hungry or thirsty can stop you from running — a real problem in a building where the hallway zombies punish noise. Barricading covers your home front while you do that work: it protects the apartment you return to between trips. Staying quiet covers the hallways themselves, because the zombies there are drawn to noise.
That also means barricading and quiet are not substitutes for each other. Sealing your door does not make the hallways safe to move through loudly, and sneaking around does not secure your apartment while you are away or resting. The routine works as a set: barricade to hold your apartment, stay quiet to survive the trips outside it, and keep food and water stocked so you are ready when supplies run short.
What is known about actually doing it
What the available material establishes is the what and the when. You can barricade your own apartment, it keeps the hallway zombies out and protects you, and it belongs in your routine from the start of the 100-day run — whether you play solo or team up with up to three friends.
The fine details — the exact placement controls, the materials a barricade uses, how much punishment it absorbs, or how zombies behave against it — are not described in the available material. Treat any specific number you hear about protection strength or duration as unconfirmed, and plan around the purpose instead: a barricaded apartment is your protected base inside a building whose shared hallways belong to the zombies. Keep it barricaded as part of the daily loop, and do not let a sealed door tempt you into being loud where the zombies can hear you.
