According to Law No. 62/2018 , all vacation rentals in Portugal – with the exception of houses – must display an approved identification plaque near the entrance of the establishment.

The size of the AL identification plate varies depending on the location of the entrance:
You can purchase the Portuguese AL plate through the AHRESP’s Balcão Único Empresarial or from other specialized suppliers, which you can find through an internet search.
The AL identification sign should be placed near the property entrance. In the case of a hostel, it must be on the outside. In any other establishment, it can be either inside or outside.
For external signs, installation should be done with stainless steel screws, ensuring resistance to weather conditions and respecting the proper distance from the wall. For internal signs, in addition to screws, alternative solutions such as specific mounting adhesives can be used, allowing for secure attachment without damaging the wall.
In any situation, it is important to ensure that the sign is clearly visible, correctly positioned, and firmly installed.
In addition to the identification plate, the law requires safety signage, especially in vacation rentals that regularly receive guests.

Emergency plan or evacuation scheme, clearly indicating emergency exits and evacuation routes.

Fire extinguisher, location of the electrical panel, and identification of gas or shut-off systems.
