In Ireland, whether or not you need planning permission for a shipping container depends on the specific use and location of the container.   Generally, if the container is going to be used for storage on your property and is not visible from the public domain, planning permission may not be required. However, if the container will be used for a different purpose, such as a dwelling or office space, planning permission would likely be required.   It's also worth noting that if you're going to place the container on a property that is located in a protected area, such as a conservation area or an area of special scientific interest, you would need to apply for planning permission. It is recommended to check with your local authorities to confirm the specific regulations in your area and to make sure that you have all the required permits before placing a shipping container on your property.
