Stellaris Sectors Not Building

While handing over control of sectors to AI in Stellaris helps save a bit of work, it sometimes leads to issues and Stellaris sectors not building is a prime example. The leading cause for most of the time is lack of resources so the best solution is to allocate more resources to sectors. Besides that, you may want to appoint governors, specialize sectors, toggle automation off/on, download and install Glavius Ultimate AI mod, … Continue reading to be able to strengthen and expand your empire in Stellaris. 

Stellaris AI Won’t Build A Thing: Suspects

All in all, features of Stellaris and their function could act up every now and then. If you notice Stellaris sectors not building, the list of possibilities includes: 

  • Lack of resources.
  • No governor. 
  • Absence of sector specialization.
  • Bugs. 

What Must Be Done

Allocate More Resources To Sectors

In case you don’t know, AI only starts building in earnest if the sector possesses at least 2,000 minerals. Hence, once it comes to Stellaris sectors not building, you should consider allocating resources to sectors. Via the Planets & Sectors menu, you may divert resources to sectors, add resources to a shared pool used by all sectors and so on. Furthermore, it won’t hurt to make sure that you have an energy surplus before letting AI take over sectors. 

Note: 2,000 minerals is too much for you? Then you could decrease that amount by going through the steps down below:

  • Step 1: Open the Stellaris folder (Steam\steamapps\common\Stellaris\common\defines).
  • Step 2: Locate a file named 00_defines.lua then open it in Notepad. 
  • Step 3: Go to the line MAX_MINERALS_STORED_SECTOR_POST =, change the value to 500 and save the change. 

Appoint Governors

If AI-controlled sectors have 2,000 minerals each but nothing is being built, you should appoint governors. Governors not only kickstart the construction of buildings but also provide bonuses. 

Specialized Sectors

It’s well-known that if left to its own devices, AI is going to focus on fixing deficits. That accomplishes little, consumes a lot of resources and limits the growth of sectors in the long run. Fortunately, it’s possible to make AI ignore the deficits by specializing sectors. If you have trouble getting AI to build things in Stellaris, try out specialization. 

Toggle Automation Off/On

Interestingly, some players have reported that “turn colony automation on” in the colony screen actually works the opposite way around. If you want the AI to handle the constructions in sectors, you must toggle “turn colony automation on” off. For good measure, you should toggle automation off/on then see how things turn out. 

Download And Install Glavius Ultimate AI Mod

None of the above work? In that case, the Glavius Ultimate AI mod is your last resort. As the name suggests, Glavius Ultimate AI is designed to address the quirks of the AI of Stellaris. At the moment, Glavius Ultimate AI is available on Steam workshop. Download and install the mod then see how things turn out. 


How long is a Stellaris playthrough? 

Commonly, a Stellaris playthrough lasts around 28 hours if you concentrate on completing the main missions. If you play as a perfectionist, you may need to spend up to 300 hours to finish the game. 

Will there be a Stellaris 2? 

The game director of Stellaris revealed that a plan for Stellaris 2 is not available for now since the team is focusing on another promising 4X game. There are still chances that the development of Stellaris 2 might start in the future though as Paradox has not outright denied it yet. 

Is Stellaris a hard game? 

For players who are not familiar with other Paradox’s titles or real-time strategy games, then Stellaris’s learning curve is pretty steep, thus requiring a lot of time to master. 

Which empire should I choose in Stellaris? 

Even though Stellaris allows the creation of a distinctive space empire with limitless customization, new players are still recommended to pick a pre-generated nation. If you know little about the game, the United Nations Of Earth is a solid choice. Playing as humans provides perspectives and there is no need to strain your brain to remember names. 

Which Origin is considered the best in Stellaris? 

When it comes to the Origin debate, Hegemon always stands out thanks to the strong foundation for expansions. In the second place, we will have the Shattered Ring Origin as it grants the players the Ring World. (Alprazolam) Other names worth mentioning are Scion, Void Dwellers, Common Ground and Clone Army. 

Which game is superior, Stellaris or Endless Space 2

Despite the fact that Stellaris offers a more open-ended experience and quality DLCs, Endless Space 2 is still rated higher since it excels in balancing the complexity and learning curve. 

Does Stellaris have an ending? 

Yes, a game in Stellaris lasts 300 in-game years by default, but the players can set an ‘End Year’ when creating the galaxy. However, a game does not usually last that long as it stops after the players have eliminated all the enemies, taken control of more than 40% of the galaxy or decided to quit. 

Should I focus on shields instead of armor? 

Overall, shields offer more benefits since they work against nearly every kind of energy weapon and cost less to make. The only downside of shields compared to armor is the inability to deflect kinetic shots. 

Are Stellaris’s DLCs worth buying? 

Obviously yes, you should purchase nearly all of the DLCs in Stellaris. Yet, not every DLC is equal to each other in terms of additions and your playstyle also decides what you get the most out of them. 

Tips And Tricks

  • Start colonizing as soon and as quickly as possible. 
  • Preparation is key in colonizing, especially around the mining district.
  • Always put your base under the protection of a fleet. 
  • Keep on researching and diversifying the warships
  • Don’t offend Fallen Empires until your empire is well-developed. 
  • Build at least two science ships and if you play with the DLCs, make that three.
