While deployed to a Villager, Houses and Animal Stables lose 1 durability each day. Herbalist Pots lose 1 durability from each harvest.
When a house reaches 0 durability, the Villager inside will remain but wont be able to work until the house is repaired. Warning: If an animal stable reaches 0 durability the Animal inside will run away and won't come back, even if they're domesticated. If a herbalist pot reaches 0 durability it will be destroyed.
How to Repair
To repair herbalist pots or animal stables, you'll need your construction worker as your active villager. Once they're active a repair option will appear under the drop menu when you click on the individual pots and stables in the career pages. Alternatively, you can remove them from your career page and repair them from your inventory.
To repair a house, make sure to make your construction worker your active villager. Afterwards go to your villager's profile page, a repair button will show up under their Villager Info.
If you'd rather not repair your structures yourself, visit the Maintenance Market and hire another player's villager to repair them. This method allows you to repair many structures in a short amount of time.
The Combat update dropped Durability from the Warrior career all together but left all the "old" equipment in the game, which is called Legacy equipment. Legacy items cannot be used in battle, but are considered rare items as they can no longer be obtained. They can be converted to their newer versions, an option you can find by clicking them in your inventory. A Legacy item having a durability above 1000% of its max durability and converting it will grant you the Durability Star trophy.
