Dirty Business Base Hub — July 2026 | Dirty Business Wiki
Build and expand your underground base in Dirty Business — rooms, upgrades, distribution, garage, street dealers, and cartel airstrip explained.
Your underground base is the physical heart of Dirty Business. Every grow light, lathe, counterfeit press, and lab bench lives here — along with the elevators, dealers, and airstrips that move product to buyers. This hub explains how base systems connect to production, what the demo includes versus full Early Access, and where to read deep dives on building, upgrades, and distribution.
Base vs Production: Who Owns What
Production guides answer what to make and how to craft it. Base guides answer where it happens and how it leaves. A perfect weapon batch still fails if secure storage is full or the elevator queue backs up. Start with the beginner guide if you have not toured your starting facility.
Core base pillars in full EA:
- Building — Room placement, expansion tiles, power routing
- Upgrades — Generators, storage, security, disposal capacity
- Distribution — Moving goods from vault to buyer
- Elevator delivery — Primary outbound route via underground garage
- Street dealers — Surface retail pressure valve
- Cartel airstrip — Late-game bulk logistics
Demo vs Early Access Base Features
The demo teaches core loop rooms, evidence disposal, and basic outbound flow — enough to finish fourteen levels without the full expansion tree. Full Early Access adds deeper upgrade paths, front companies, street dealers, underground garage expansion, and the cartel airstrip for high-volume contracts tied to advanced production lines.
Demo players should still read building and upgrades — principles carry into EA even if some doors stay locked.
Underground Garage and Logistics
The underground garage anchors haul loops between production floors and street-level exits. Vehicles, crates, and elevator timing interact here. Bottlenecked garage access looks like “production is slow” when the real issue is logistics — see elevator delivery before buying another grow light.
Assign clear one-way paths: raw in from orders, finished out to delivery staging. Co-op groups benefit from a dedicated runner role described in co-op.
Front Companies and Laundering Layer
Front companies (full EA) convert street-facing operations into cleaner books — pairing naturally with counterfeiting and high-volume weed strains. They sit in the distribution layer rather than pure crafting; overview in base distribution.
Unlock front companies after basic delivery works reliably. Running laundries before disposal is upgraded invites scrutiny without payoff.
Heat, Security, and Disposal Inside the Base
Every expansion increases output potential and evidence volume. Disposal rooms are base infrastructure, not optional flavor. Upgrade burners and bins through base upgrades in sync with new production lines from production hub.
Security upgrades reduce raid impact as you scale street dealers and visible surface activity. Balance growth with evidence disposal the same way you balance power draw.
Linking Base Progress to Production Tier Planning
Use the production tier list to decide what to make next, then use base guides to unlock capacity before switching lines. Typical sync points:
| Production unlock | Base prerequisite |
|---|---|
| Second weapon type | Secure storage II |
| Counterfeiting | Dry rooms + disposal II |
| LSD lab | Power upgrade + chemical disposal |
| Cartel shipments | Airstrip + garage throughput |
Workers and Base Throughput
NPC workers path through your layout. Bad door placement creates idle workers and phantom labor costs. Read hire workers after shaping rooms in building. Workers cannot fix a base that routes through a single choke-point elevator at rush hour.
Orders Terminal and Base Interface
The order terminal is base infrastructure linking to complete orders. Keep terminal access within sprint distance of storage and primary delivery staging — a small layout detail that saves hours over a save file.
Controls, Camera, and Multi-Floor Navigation
Multi-floor bases demand comfortable controls and keybinds. Vertical navigation confusion slows expansion more than missing one upgrade tier. Fix movement issues via troubleshooting before major rebuilds.
Walkthrough and Update Context
Story-gated room unlocks appear in walkthrough mission order. Mechanical unlocks follow cash and upgrade trees here. When patches add rooms or rebalance power costs, updates list changes — reconcile before following old build diagrams from forum posts.
Recommended Reading Path
- Building — Shape your first expansion
- Upgrades — Fix power, storage, disposal
- Elevator delivery — Ship first consistent orders
- Distribution — Add dealers, fronts, airstrip
- Production hub — Scale what your base can support
Community tools may add layout planners over time. Your base is the constraint that turns production knowledge into actual profit — treat expansion as seriously as any tier list ranking.
Frequently Asked Questions
Quick answers to the most common questions.
What base features are missing in the demo?
The demo covers core rooms and disposal but not full EA expansions like street dealers, cartel airstrip, and complete front company trees.
Should I expand rooms or upgrade existing ones first?
Upgrade power, storage, and disposal before adding new production rooms. Empty tiles do not help if infrastructure is capped.
How does the underground garage work?
It connects production floors to outbound delivery. Elevator timing and crate staging are covered in the elevator delivery guide.
When should I unlock street dealers?
After elevator delivery runs reliably and disposal handles increased surface activity.
Where does base planning meet production?
