According to the Cambridge Dictionary, intend means "to have as a plan or purpose".
In my opinion, it is mainly used in the active voice for a plan (where the person or entity with the plan is the subject), and the passive voice form for purpose (where the patient is the thing that has a purpose).
The council intends to demolish the factories and replace them with housing - active voice
The life jackets are intended for emergency use only - passive voice.
Intention is used only for a plan, and the correct usage is like this:
The intention is to remove all factories and replace them with housing.
