You can have more than one of the exact same facilities, BUT they must be placed on different farms.
The exception to this rule is when there is a Turbo version of the regular facility, in which case you can have one of each on the same farm.
For example you could have an Oil Refinery and a Turbo Oil Refinery on the same farm.
If you have two of the exact same facility on the same one farm, like 2 wineries, they will both look each one is making products because the information is copied in the duplicate so that it doesn't matter which one you open. When you store from the winery, you are only getting products from one of them.
You could have 4 winery facilities, one on farm 1, one on farm 2, one on farm 3 one on farm 4 and then all 4 of them would produce products.
If you try to buy a facility and already have one on that farm you will see a warning pop up. This is an example of one...

If you have a lot of facilities on a farm and are not sure which ones you have or don't have on that farm, you can do the following:- Open the Store
- Click on "**Facilities**
- Click on the Funnel top right of the window and choose either "Owned", "Not Owned" or "Not in this Farm"
OR if you could use Farm Stats to locate them.
WARNINGS!!!!!!
If you are taking part in the Neighbourhood Chains Contest and the facility is listed for the contest, do not store the facility until the contest is over or you will abandon the contest.
The NCC warning is not the same information as the warning for storing a facility, you have to read what it says in the message to know if you are storing a facility that is part of the Neighbourhood Chains Contest!!!
If you ignore the message and click the green check mark you will store the facility and abandon the contest.
Example of the NCC warning:
Storing a facility that is not part of the NCC to move a to another farm.
Make sure there is no pending production left in it, and you have stored the products BEFORE you move it to another farm or you will lose both what it is making and what you have not stored!
The only time you will be warned is if you manually store the facility by clicking on it on your farm and clicking on "Add to Storage". If you use another method to store the facility like the "Add Item to Storage Tool" or the "Tower Crane" you will not see the warning.
Example of the message:
