It is possible to live in Portugal in a motorhome; there is no law prohibiting it. However, there are some conditions to meet. Without the need for a permanent address, you can park on the public road for up to 30 consecutive days, but opening the awnings is not allowed. For this, you need to be in designated motorhome areas, usually paid.

To have an official address, you must park on private land, which can be owned or rented. If the land doesn't have a registered address, you'll need to request address registration through CTT (Portuguese postal service).
