Chumash Is the Bunker to Buy, and the Upgrades Make It Pay
Buy the Chumash Bunker for $1,650,000, then add the Equipment upgrade for $1,155,000 and the Staff upgrade for $598,500. That is the setup that makes money.
With both upgrades fitted, your staff turn bought supplies into weapons stock worth $7,000 per unit, or $10,500 per unit sold to Los Santos. A full bunker sells there for $1,050,000.
All 11 bunkers are identical inside and produce at exactly the same rate. Location changes only your driving, so Chumash wins because its coastal highway run into Los Santos is short and simple.
Key Takeaways
- Chumash at $1,650,000 is the best-value bunker; Farmhouse at $2,375,000 is the premium alternative, and every bunker in between earns exactly the same money.
- The Equipment upgrade ($1,155,000) and Staff upgrade ($598,500) are essential — together they lift stock from $5,000 to $7,000 per unit and speed production up.
- Always buy supplies: a full bar costs $75,000, while stealing usually fills only a fifth of the bar per mission and pauses production.
- One full supply bar becomes 20 units of stock in about 2 hours 20 minutes fully upgraded, worth $210,000 sold to Los Santos.
- A full 100-unit bunker sells for $1,050,000 in Los Santos against $375,000 of bought supplies — about $675,000 profit, before any weekly bonuses.
- Sell at 25 units or less to guarantee a single delivery vehicle you can handle completely solo.
1. What the Bunker Business Actually Does
The Bunker arrived with the Gunrunning update in June 2017. It is an underground weapons factory: you feed it supplies, your staff manufacture stock, and you deliver that stock to buyers for cash.
Everything runs from the Disruption Logistics laptop inside the bunker. From that one screen you resupply, sell stock, assign staff, buy upgrades and manage research.
To use the laptop you must be registered as a CEO, VIP or MC President. The business only produces while you are in a session, so it rewards players who play regularly.
The bunker also stores a Mobile Operations Center if you buy one, and owning a bunker later feeds Sporting Goods into a Nightclub warehouse. It earns on its own first, though.
2. All 11 Locations Compared: Price Buys Driving Time, Nothing Else
The cheapest bunkers are Paleto Forest at $1,165,000, Raton Canyon at $1,450,000 and Lago Zancudo at $1,550,000. All three sit in the far north or far west of the map.
The middle of the range is Chumash at $1,650,000, Grapeseed at $1,750,000, Route 68 at $1,950,000 and Grand Senora Oilfields at $2,035,000. Only Chumash and Route 68 deserve serious thought here.
The expensive end is Grand Senora Desert at $2,120,000, Smoke Tree Road at $2,205,000, Thompson Scrapyard at $2,290,000 and Farmhouse at $2,375,000, the priciest bunker in the game.
Chumash is the recommendation for most players. It sits just outside Los Santos on the western highway, so the better-paying Los Santos deliveries start almost on the city’s doorstep.
Farmhouse is the premium pick. Its flat run down the Senora Freeway is fast and easy, but you pay $725,000 more than Chumash for the same production, the same stock and the same payouts.
Route 68 is the compromise at $1,950,000, central in the Grand Senora Desert with good roads in every direction. It still costs $300,000 more than Chumash for longer city drives.
Avoid Paleto Forest unless you got it free with the Criminal Enterprise Starter Pack. Saving $485,000 against Chumash costs you a long northern drive on every single sale you ever make.
If you buy badly, you can trade a bunker in against a new location and recover half its purchase price. Supplies, stock and unfinished research are lost in the move, but completed research unlocks carry over.
3. Buying and Setup, Step by Step
Wait for the introductory call from Agent 14, then open Maze Bank Foreclosures on your in-game phone or laptop. Bunkers appear there once that call has happened.
Choose your location, then look carefully at the renovation list before confirming. Styles, personal quarters and the shooting range can all be added later, so skip them at purchase.
Pay, travel to the hatch entrance and go inside. Register as a CEO, VIP or MC President, sit at the laptop and open Disruption Logistics to begin.
Setup is one delivery job: collect the Duneloader parked at an Ammu-Nation and bring it back to the bunker. Agent 14 then walks you through the manufacturing, research and storage areas.
Completing setup leaves you with a full bar of supplies already in place. Set your staff to manufacturing before you leave, and production starts immediately.
4. The Upgrades That Matter, and the Ones That Do Not
The Equipment upgrade costs $1,155,000 and is the first buy. It speeds up manufacturing and research, raises the value of your stock and makes each bar of supplies stretch further.
The Staff upgrade costs $598,500 and is the second buy. More staff speed production up again and raise stock value further, completing the profitable version of the business.
The numbers show why both matter. With no upgrades a unit of stock is worth $5,000 and takes 10 minutes to produce; with both fitted, a unit is worth $7,000 and takes about 7 minutes.
The Security upgrade costs $351,000 and reduces how often raids threaten your stock. It is optional if you sell regularly, and worth it if you like leaving a full bunker sitting.
Renovations change nothing about income. Bunker styles cost $215,000 or $290,000, personal quarters $265,000, a shooting range $740,000, a gun locker $175,000 and bunker caddies $85,000 or $120,000.
Daily fees are modest but real. You are charged $2,000 per in-game day for the bunker while registered as a boss, rising to $4,500 with all three upgrades fitted, at the time of writing.
5. Supplies: Buy Them, Do Not Steal Them
Supplies are the raw material for everything the bunker does. From the laptop you can pay to have them delivered, or launch a steal mission and fetch them yourself.
Buying is priced by how empty the bar is: filling a completely empty bar costs $75,000, and topping up a partly used bar costs proportionally less. Delivery arrives in about 10 minutes.
Stealing sounds free and is not. A typical steal mission fills only about a fifth of the supply bar, so filling up can take up to five missions, and production waits while you run them.
The maths settles it for most players. The $75,000 you save by stealing costs you far more than $75,000 worth of playing time that could be spent on heists or other businesses.
Steal supplies only early on, when cash is genuinely tight, or when you simply enjoy the missions. The moment the bunker is upgraded, buying becomes the routine.
6. Production Numbers: What a Full Bunker Is Worth
Keep every member of staff on manufacturing and one full supply bar produces 20 units of stock. Fully upgraded, that takes about 2 hours 20 minutes of session time.
Those 20 units sell for $140,000 to nearby Blaine County buyers or $210,000 delivered to Los Santos. Against the $75,000 supply cost, one bar earns about $135,000 profit on a Los Santos sale.
Repeat the resupply five times and the stock bar reaches its 100-unit maximum. Total supply cost is $375,000 and total production time is about 11 hours 40 minutes, fully upgraded.
That full bunker sells for $700,000 in Blaine County or $1,050,000 in Los Santos. Selling to Los Santos leaves roughly $675,000 profit per full run, before weekly event bonuses.
Treat these as base figures at the time of writing. Rockstar regularly runs Gunrunning bonus weeks that raise sell payouts or production speed, and weekly discounts can cut the purchase and upgrade prices.
7. Selling Stock Without Losing It
Always choose Los Santos when the timer allows. It pays 50 percent more than Blaine County for exactly the same stock — $10,500 per unit instead of $7,000 in a fully upgraded bunker.
The solo rule is simple: sell at 25 units of stock or less. At that level the game gives you one delivery vehicle, which one player can comfortably deliver alone.
Let stock climb higher and a sale can hand you two or three vehicles on a single timer. Most sell scenarios allow 15 minutes, so extra vehicles are where solo sales fail.
Since 2022, sell missions work in invite-only sessions, and that is where most players should sell. Nobody can destroy your delivery vehicle in a session that contains only you.
A public session pays a High Demand bonus that grows with the number of rival players present. It is real extra money, but it is paid for with real risk to the whole load.
While the bunker produces, Agent 14 also periodically offers an Ammu-Nation delivery contract worth $50,000. It uses a separate vehicle and does not touch your sellable stock, so take it when it appears.
8. Raids: The Real Risk, and How to Keep It Low
A bunker holding stock can be raided by NPC enemies, who will steal product if you fail to defend it. Losing a raid means losing stock you have already paid supplies for.
Raids can only trigger while you are registered as a CEO, VIP or MC President with stock on hand. Deregistering when you are idling around removes the trigger entirely.
The Security upgrade halves how often raids happen, which is its whole value. It does not make a raid easier to win; it simply makes raids rarer.
The cheapest protection is habit: sell in smaller, regular batches instead of hoarding a full bunker for days. Less stock sitting underground means less that a raid can take.
9. Research: Worth Doing Once, Not Worth Living On
Instead of manufacturing, staff can be assigned to research, using supplies to unlock weapon and vehicle modifications. There are 51 research projects in total.
The unlocks include genuinely useful gear such as explosive sniper rounds and Mk II weapon upgrades, alongside vehicle modifications and cosmetic items you may never buy.
Research makes no sellable stock while it runs. Splitting staff between both jobs slows each one down, so a split bunker earns less and researches slowly at the same time.
The faster route is fast-tracking. From the laptop you can pay to finish the current project instantly, at up to $225,000 per project — fast-tracking all 51 could cost up to $11,475,000.
The sensible plan is to keep staff on manufacturing for income and fast-track only the handful of unlocks you actually want. Research is a shopping list, not a second income.
10. Mistakes That Cost Bunker Owners Money
The most expensive mistake is buying the cheapest bunker. Paleto Forest saves money once and then taxes every Los Santos delivery with the longest drive on the map, forever.
The second mistake is judging the business before upgrading it. An unupgraded bunker produces slowly and cheaply, and buying its supplies can barely break even; the upgrades are the business.
Hoarding is the third mistake. A full bunker sold solo means multiple vehicles on one timer, maximum raid exposure and the most money lost if a single delivery goes wrong.
Skipping Los Santos to save a few minutes is the quiet mistake. Giving up the 50 percent distance bonus on every sale costs far more over a month than the driving ever does.
Finally, do not waste time hunting for a shortcut around the grind. There is no legitimate cheat or glitch route to a full bunker, which is exactly the point explained in why there is no money cheat in GTA games.
11. How the Bunker Fits With Everything Else You Own
The bunker works best as background income. Buy supplies, set staff to manufacturing, then go and run the Cayo Perico heist, Agency contracts or Acid Lab sales while it produces.
Later, a Nightclub adds a second layer: its warehouse can accrue Sporting Goods because you own a bunker, so the same property quietly feeds two businesses at once.
That background role is also why the bunker stays worth owning late into the game’s life. It asks for minutes of attention and returns six-figure sales in exchange.
Its long horizon raises a fair question about the future game, and will GTA Online progress carry over to GTA 6 is still unconfirmed by Rockstar, so buy a bunker for the money it makes in this game.
For the same reason, it helps to know what is different between GTA 6 and GTA 5 and what GTA 6 Online actually is so far — a successor is coming, but this bunker pays you in the game you can play today.
Frequently Asked Questions
What is the best bunker location in GTA Online?
Chumash, at $1,650,000. Every bunker produces identically, and Chumash gives the shortest, simplest drives to the better-paying Los Santos buyers of any sensibly priced location.
How much does a fully upgraded bunker cost in total?
A Chumash bunker with the Equipment and Staff upgrades costs $3,403,500 in total. Adding the optional Security upgrade brings the full spend to $3,754,500, before any weekly discounts.
How long does a full bunker take to fill?
About 11 hours 40 minutes of session time with both production upgrades, using five full bars of supplies. Each single bar takes roughly 2 hours 20 minutes.
How much profit does one full bunker sale make?
Sold to Los Santos, a full bunker pays $1,050,000 against $375,000 of bought supplies, for about $675,000 profit. Blaine County pays $700,000 for the same stock.
Should I buy supplies or steal them?
Buy them. A full bar costs $75,000 and arrives in about 10 minutes, while stealing usually fills only a fifth of the bar per mission and pauses production throughout.
How much stock can I sell solo safely?
Sell at 25 units or less. That guarantees a single delivery vehicle, which one player can deliver comfortably inside the timer, especially in an invite-only session.
Is the Security upgrade worth buying?
Only if you regularly leave large amounts of stock sitting in the bunker. It halves raid frequency, but players who sell in small, regular batches can safely skip it.
Should my staff do research or manufacturing?
Manufacturing, if money is the goal. Research produces no sellable stock, so most players fast-track the few unlocks they want, at up to $225,000 per project, instead.
Can my bunker be raided while I am offline?
No. Raids trigger while you are in a session, registered as a CEO, VIP or MC President, with stock on hand. Deregistering when you stop actively playing removes the risk.
Can I move my bunker to a better location later?
Yes. Buying a new location trades the old one in for half its purchase price. Your supplies, stock and unfinished research are lost, but completed research unlocks stay unlocked.
Conclusion
The bunker is not the fastest money in GTA Online, and it was never meant to be. It is the business that pays you for time you were already spending in the game.
Buy Chumash, fit the Equipment and Staff upgrades before judging anything, buy every bar of supplies, and sell modest batches to Los Santos in a quiet session.
Run it that way and the pattern repeats itself for as long as you play: a few minutes of buying and driving, and hundreds of thousands of GTA dollars back.
