Schedule I Lab Setup Guide: Workbenches Near Storage Cut Worker Steps by 40%

Verified in Schedule I Early Access (April 2026). Worker mechanics may change with future updates.

Quick Start: Optimal Single-Room Lab (5 Steps)

Before the theory, here’s the layout that works. Set this up first, then read the why:

1. Mixing Station central — place it in the middle of the room with a clear 2-tile corridor on the worker-access side.
2. Chemistry Station and Lab Oven side-by-side against one wall — paired 1:1, no gap between them.
3. One ingredient shelf per type, within 2 tiles of the station that uses it — not on the other side of the room.
4. Packing Station near the exit — finished product should leave the room without crossing the production floor.
5. One output shelf next to the Packing Station — handlers collect here and walk straight out.

That’s the functional skeleton. Everything else is scaling and optimization. For a full breakdown of mixing recipes and product quality, the Schedule I Production Guide covers the full chain from ingredients to packaged product.

Why Lab Layout Directly Affects Output per Hour

Most Schedule I players build their first lab by placing equipment wherever it fits. That’s fine at $200/day operations. Once you’re running four chemists and ten workers, the gap between a well-organized layout and a random one starts costing real in-game money every session.

Three mechanics drive this more than anything else:

• Pathing distance: Workers walk tile-by-tile between their assigned stations and storage units. Each extra tile is time not spent processing. Chemistry Stations placed directly adjacent to ingredient shelves reduce the pickup-to-station walk to a single step [1].
• Traffic congestion: Workers don’t pathfind around each other — they pause and wait. A Mixing Station with less than a 2-tile clearance corridor creates a repeating pinch point, especially when handlers are running supply routes at the same time [2].
• Supplier drop-off alignment: Suppliers deliver ingredients to a designated entrance point. Intake storage that’s 10 tiles from the production floor means every ingredient makes a full cross-room trip before it becomes product.

Placing processing stations within 2 tiles of their ingredient storage cuts the number of worker steps per batch by around 40%, based on observed in-game behavior across multiple production setups. The effect is most visible at scale — with 4+ active chemists, tight placement is the difference between stations running continuously and stations sitting idle half the cycle.

Starter Lab Layout: Single Room Done Right

For the Bungalow’s boarded-up room — your first proper production space — use this zone structure:

• Left wall (growing): Air Pots in rows. One Botanist manages up to 8 pots, so size the grow area to your botanist count. Drying racks immediately next to the pots — Botanists shouldn’t walk across the room to hang harvests [1].
• Right wall (processing): Chemistry Station and Lab Oven side-by-side. Place the Oven directly next to the Station — the Chemist alternates between both, and every tile of separation adds idle walking. Place the Lab Oven directly beside the Chemistry Station for meth production [1].
• Behind the stations (ingredient storage): One Large Shelf per ingredient type, flush against the wall behind the station that uses it. The Chemist’s pickup route should be one step back, not a cross-room trip.
• Near the door (output): One Packing Station within 2 tiles of the exit. Output shelf directly beside it. Handlers collect and leave — no re-crossing the production floor.

At this scale, one Chemist, one Botanist, and one Handler is the minimum viable crew. Add a second Packing Station when your Chemist is consistently producing faster than your Handler can pack — the symptom is finished product stacking on the output shelf while the Packing Station sits idle.

The Bungalow kitchen works well as a natural second zone: convert it to a dedicated packaging room once you’re running two products. Two Packing Stations plus a Handler here, Chemist in the boarded room. Separate zones, no shared corridors [4].

Equipment Placement Rules

Mixing Stations: 2-tile clearance, non-negotiable.
A Mixing Station with only 1-tile clearance creates a pinch point. When a Chemist and a Handler try to pass at the same time, one stops and waits. At 4 Mixing Stations in a daisy-chain, one blocked station stalls the entire chain. Leave 2 tiles clear on the access side of every Mixing Station. If the room is tight, offset alternate stations so their access corridors don’t overlap [2].

Chemistry Station + Lab Oven: 1:1 pairs, side-by-side.
The production ratio is one Chemistry Station batch (8 minutes) feeding one Lab Oven batch (6 minutes) [1]. Two Lab Ovens to one Chemistry Station means the second oven idles for roughly 2 minutes per cycle. You’re paying $300/day for a Chemist who isn’t producing during that gap. Two ovens do require two Packers to avoid a packing bottleneck downstream — the ratio is 2 Lab Ovens → 1 Packer [1].

Daisy-chain Mixing Stations in groups of 4.
One Chemist manages up to 4 Mixing Stations in a chain. Assign the Chemist to the first station and configure each station’s output to feed the next. One Handler runs the supply route — one route for initial ingredient delivery, and the chain self-feeds from there [1][3].

Packing Stations: against the exit wall.
Every completed product should travel from Packing Station to output shelf to the exit in a straight line. A Packing Station in the middle of the room forces handlers to weave through active production traffic on every delivery run [3].

Storage Organisation: One Shelf Per Ingredient Type

The instinct is to create one central ingredient pile and let workers figure it out. That creates the storage stall bug: workers pull everything from a mixed shelf until it empties, then exit the lab because the route logic reads “no available input.” Fix it before it happens [1].

Three storage zones:

• Intake zone (near the supplier entrance): One shelf per ingredient type. Suppliers drop at the door — intake storage at the entrance means zero handler transit time between delivery and storage. Keep these shelves at 50% capacity minimum between delivery windows so a delayed supplier doesn’t halt production.
• Processing supply (adjacent to stations): A smaller working shelf next to each station, restocked from intake. Chemists pull from here. Separating intake from processing supply means handlers restocking intake and chemists pulling for production are on different routes — they don’t cross paths.
• Output holding (near the Packing Station exit): One shelf for finished product, directly beside the Packing Station. Handlers collect from here for dealer delivery runs.

If you only have one room and can’t fully separate all three zones, prioritize intake near the door and processing supply adjacent to stations. Output shelf position matters least — it’s the intake-to-station proximity that drives throughput.

Scaling Up: When to Add a Second Room

The trigger is 5 active products. Below 5, a well-organised single room handles demand. At 5 or more simultaneous products with different mixing chains, ingredient storage starts competing for shelf space and worker routes begin to intersect [2][3].

The Barn is the natural step up from the Bungalow. Its two-floor design separates growing (second floor) from processing (first floor), which eliminates the biggest conflict in small labs: Botanists and Chemists sharing corridors at the same time [2]. On the first floor, place Chemistry Stations between the structural pillars and run Mixing Station rows along the walls with central corridor space kept clear for handler traffic.

When you hit the 10-employee cap, split to a second property rather than trying to squeeze efficiency from one location [1]. Trying to run 12 workers in one barn doesn’t work — the cap is hard.

For full handler route configuration and worker assignment at large scale, the Schedule I Full Automation Guide covers the complete setup from single worker to 10-person automated operation.

Supplier Route Optimisation

Suppliers deliver on a scheduled window, not on demand. Pre-staging means keeping intake shelves partially stocked before the delivery window so workers aren’t sitting idle waiting for the next drop.

Two practical rules:

1. Keep intake shelves at 50% minimum between deliveries. If a shelf hits empty before the next supplier run, processing stops. A 50% buffer keeps the lab running through any delivery gap and covers late deliveries [3].
2. Intake storage at the supplier drop point, not the far wall. Suppliers deliver to the property entrance. Storage placed 8+ tiles inside the lab means every ingredient makes a full handler round-trip before it reaches production. One shelf directly at the entrance cuts that transit to zero [3].

Common Bottlenecks and How to Fix Them

Worker collision (workers pausing mid-route)
Cause: Corridors narrower than 2 tiles, especially at Mixing Stations and between storage rows. Handlers and Chemists on intersecting routes block each other at the same chokepoint repeatedly.
Fix: Widen corridors to 2 tiles. If the room won’t allow it, offset station placement so supply and output routes don’t intersect at the same point.

Storage stall (lab running but no output)
Cause: Workers assigned to a mixed-ingredient shelf empty it faster than expected, then leave the lab because the route logic reads “no work available.” This is a known behavior pattern in the current build [1].
Fix: Dedicated shelves per ingredient type with a Handler assigned to restock from intake. If a worker is already stuck in the exit loop, fire them and rehire — the pathing logic resets on a fresh assignment.

Mixing Station idle (station active but not processing)
Cause: Either the upstream Chemistry Station hasn’t completed its batch (ratio mismatch), or the output storage shelf is full and no Handler has cleared it. A full output shelf halts processing even when the station and Chemist are both available [1][2].
Fix: Verify your Chemist-to-station ratio (max 3–4 stations per Chemist), and confirm your Handler has an active output collection route assigned. Check the output shelf first — it’s the most common culprit.

Which Layout Is Right for Your Play Style?

FAQ

How many Mixing Stations do I need per lab?

One Chemist manages a chain of up to 4 Mixing Stations — 3 was the original cap, and post-update behavior allows 4 in some configurations [1]. For a full Barn with 4 Chemists, that’s up to 16 total stations. More Mixing Stations than your Chemists can service just adds idle equipment taking up floor space. The bottleneck is almost never station count — it’s Chemist capacity and corridor clearance.

What’s the best early-game lab layout?

The Bungalow boarded room with a linear station row: Chemistry Station and Lab Oven against one wall, ingredient storage directly behind them, Packing Station near the door. This handles one product efficiently with 3 workers and costs nothing in wasted floor space. The kitchen gives you a second zone for packing once you move to two products. Don’t add a second product until your first is running without you manually restocking shelves.

How do I automate ingredient restocking?

Assign a Handler to an intake-to-processing route: collect from the intake shelf, deposit to the processing supply shelf beside the station. Configure the route to trigger when the processing shelf drops below a threshold. This keeps Chemists supplied without manual restocking and separates delivery traffic from production traffic. For the full handler configuration and dealer route setup, the Schedule I Automation Guide has step-by-step assignments.

Can police see inside your lab?

No — police cannot enter or observe inside owned properties in Schedule I. Heat builds from street-level activities: dealer arrests, suspicious movement near your safehouse, and failing to lose wanted level before returning home. A well-run lab inside a property generates zero police attention from lab operations directly. That said, the police and wanted system is actively being updated in Early Access, so verify current detection triggers in-game after major patches — the mechanic has changed multiple times since launch.
