Fallout 4: How to Increase Settlement Happiness

Build Solid Defenses

If you’re seeing the hazard triangle next to the defense stat on your Pip-Boy or at the top of your screen when in workshop mode, you may have discovered the cause of your happiness problems. A high defense rating makes your settlement a lot less liable to a raider invasion and so will make your settlement’s inhabitants feel a lot more at ease.

Build some turrets and connect them to generators or build some guard posts and assign one of your settlers to man both of them. A single guard can man up to three posts and can, therefore, boost your defense rating by 6. Keeping settlers feeling comfortable and safe in your base will contribute greatly to increasing your happiness rating.
