Rust Apartment Monument Base Guide - Rooms, Upkeep and Master Key

What players want to know: The Apartment Monument lets you rent a room instead of building a base - but it's not fully safe. Rooms are raidable via the Master Key mechanic, upkeep expires if you don't feed scrap regularly, and the value estimator signals how juicy your room looks to raiders. This guide covers exactly how to set up, what to rent, and how to stay under the radar.

1Room Types and Costs

One room per player. You cannot rent multiple rooms simultaneously. Choose your tier based on playtime and scrap budget.

Basement

~25 scrap + 10/day

Basic storage (~134 slots), T1 workbench, sleeping bag, small locker, stove, water/toilet. Enough for kits and essentials.

Best for: Solos, grubs, first-time renters

Standard

~150 scrap + 50/day

More storage (~282 slots), better locker, bed, fridge, views. Balance of cost and space for active players or duos.

Best for: Small groups, mid-wipe

Penthouse

350+ scrap + 100/day

Largest multi-level room, best amenities. Limited availability. High upkeep - only viable if you're already scrap-rich.

Best for: Rich players, flex only

2Step-by-Step Setup

First

Find the Monument on Map

The Apartment Monument spawns in lower-threat areas. Check your map on wipe day or fly/scan for it. The exterior and common areas are safe zones with turrets - don't fight inside shared spaces.

Rent

Rent a Room at the Concierge Desk

Go to the front desk (concierge) inside the apartment tower. Select your room tier and pay the initial scrap cost. You'll receive access to your assigned room immediately.

Pay additional scrap into the room's red upkeep box (works like a Tool Cupboard). Load it up front for multiple days of security.

Setup

Set Up Your Room Immediately

Place a sleeping bag or bed for a spawn point. Store loot in the provided boxes and lockers. Use the built-in workbench, stove, and utilities. Note: you cannot add your own structures inside the room - no building privilege.

Check the concierge if you forget your room number later.

Optional

Rent a Shop in the Courtyard

~100 scrap down + ~10 scrap/hour. Lets you run a vending machine and hire an NPC seller. Safe-zone trading with zero base defense needed. One shop per player.

Skip this if you're not planning to trade - it adds daily scrap cost for marginal benefit early wipe.

Daily

Manage Upkeep and Stay Under the Radar

Feed scrap to the upkeep box before the timer expires. There's a grace period, but don't rely on it. Check every session.

For raid defense: The Master Key (bought from basement NPC, ~1,000 scrap) lets any player open your room for a 5-minute window. Keep high-value items hidden or stored in a way that the room's value estimator reads as "low" or "medium".

Don't store explosives or stacks of valuable resources if you want to stay under the radar.

3Key Decision Points

Which Room Tier

Start Basement. It's enough for kits and basics. Upgrade to Standard if you're consistently generating more loot than it fits. Only go Penthouse if you have 1,000+ scrap and consistent uptime.

Full Wipe vs Temp

Works as a full-wipe base for part-timers who hate upkeep grinding. Use as a spawn hub and storage while also building a traditional base nearby if you play longer sessions. Decide based on daily playtime.

Master Key Defense

Keep room value low. Don't store explosives or stacked resources. If others buy a Master Key to raid you, the 5-minute window is your exposure. Spread high-value items across multiple lower-profile stashes if possible.

Solo vs Group

Best for solos and duos. Groups can use it but rooms limit per-player capacity. Clans may find the per-room restriction frustrating for shared storage.

4Common Mistakes to Avoid

Letting upkeep expire. When the timer runs out you lose access and potentially your loot. Feed the upkeep box proactively at the start of every session, not just when it's close to empty.

Storing explosives or obvious high-value items. The room value estimator signals "high value" to anyone casing the floor. This directly attracts Master Key buyers to your door.

Assuming it's 100% safe. Rooms are raidable via the 5-minute Master Key window. Don't AFK with the door open or assume safe-zone rules apply inside your own room.

Rushing the Penthouse on day one. Test the Basement first to see if the monument suits your playstyle before committing to expensive upkeep. You can only rent one room at a time anyway.

Ignoring monument location relative to your farms. If it spawns far from key resource nodes or the train network, the back-and-forth adds significant time. Pair with a nearby secondary stash if needed.
