The Shelter sets your settlement's population ceiling. This guide explains exactly what it does, what it doesn't, and how to handle the eight-Shelter upgrade grind without wasting effort on imagined benefits.

Terminology Note

The building covered here is named Shelter (sometimes Survivor Shelter) in the in-game UI and official documentation. A handful of community guides use the term "Dormitory" — they are referring to the same building. This guide uses the in-game term throughout.

What the Shelter Actually Does

Four functions, in rough order of how often they matter:

Population capacity. Shelters set the ceiling on how many Survivors your settlement can hold.
Survivor well-being stats. Upgrading the building and its interior furniture improves Sleep Quality, Comfort, Mood, and Warmth.
Backup sick-bay. Before the Clinic is built (Furnace 4), and any time the Clinic's beds are full, sick Survivors recover at the Shelter — more slowly than at the Clinic, but they recover.
Building power. Each Shelter level adds to your overall building power total.

Survivors themselves replenish over time after losses. There is no manual "recruit Survivor" action — when Survivors die, replacements arrive on their own pacing.

Hard Caps

These limits are confirmed and have not been observed to change at any progression tier:

Metric	Value
Maximum Shelters that can be built	8
Maximum Shelter building level	10
Maximum interior furniture level	20
Maximum Survivor population	32

[!NOTE] Shelters do not have Fire Crystal upgrade tiers. Once a Shelter reaches Lv. 10, it is finished for the rest of the game.

Shelter Unlock Schedule

Shelter slots unlock progressively as your Furnace levels up:

Furnace Level	Shelter Slots Unlocked
1	Shelter 1 and Shelter 2
4	Shelter 3
5	Shelter 4
6	Shelter 5
7	Shelter 6
10	Shelter 7 and Shelter 8

Upgrade Mechanics: The Triple Rule

The Furnace caps the building level. A Shelter cannot exceed your current Furnace level.
The furniture gates the building. Before a Shelter can be upgraded, all furniture inside (Bunk Bed, Desk, Bookshelf, etc.) must be maxed for the current tier.
Each Shelter is upgraded independently. You will run the upgrade loop eight separate times across your account's lifetime.

The Bunk Bed is the most critical item for capacity. Other items like the Heater and Rug contribute to well-being stats (Sleep Quality, Warmth, Comfort, Mood).

The Eight-Shelter Workload

Across an account's lifetime, you will manage 8 Shelters, each progressing to Lv. 10.

80 building-level transitions.
~1,200+ furniture upgrade actions.

There is no skip path. This is foundational infrastructure that you will work on incrementally from Furnace 1 through the late mid-game.

How Survivor Population Actually Works

The Shelter sets the ceiling. It does not pull Survivors in faster.

Ceiling only: Upgrading past your current population raises the cap for future arrivals.
Replenishment: If you are below cap, check your environment (sickness, cold, food). Replenishment happens on its own pacing.
Cap is 32: Once at 32/32, additional levels only provide minor stat and power bonuses.

Sickness and the Clinic

Sick Survivors prioritize the Clinic. If beds are full, they recover at home (the Shelter) at a slower rate.

Lead Pack vs Trail Pack Strategy

Don't push all 8 Shelters in lockstep. It is inefficient. Treat your roster as three tiers:

Lead Pack (1–2 Shelters): Always at your Furnace ceiling. These clear prerequisite checks for Furnace upgrades.
Mid Pack (3–4 Shelters): Trail by 1–2 levels. Upgrade opportunistically when resources are high.
Tail Pack (1–3 Shelters): Trail by 3+ levels. Use these to soak up surplus resources or clear "bulk" prerequisites later.

Why Split?

Resource Release Valve: Tail Shelters absorb surplus wood/coal during slow periods.
Queue Flexibility: Spreading work ensures you almost always have one building available to progress while others are locked.

Common Misconceptions

"Upgrading summons survivors." False. It only raises the cap.
"Each shelter holds 4 survivors." Likely, but the 32 cap is the only documented figure.
"VIP raises the 32 cap." No official source confirms this.
"Shelters need Fire Crystals." They don't. Lv. 10 is terminal.

Known Ambiguities

Per-level capacity: The exact population gain per building level is not published.
Bed mapping: Whether official "bed" counts map 1:1 to the Bunk Bed furniture item.
Cap modifiability: Whether future events or alliance tech might eventually raise the 32/8 caps.

For now, plan around the hard caps: 8 Shelters, 32 Survivors, Lv. 10 building.
