How to Register a Property for Alojamento Local (AL) in Portugal: Step-by-Step Guide, Including SIBA
Portugal remains one of Europe’s most attractive destinations for short-term rentals. If you own a property and want to rent it legally to tourists, you must register it as Alojamento Local (AL).
In this guide, we’ll walk through the step-by-step process to register a property for AL in Portugal, including the requirements, documents, and other legal obligations.
What Is Alojamento Local (AL)?
Alojamento Local (AL) is the Portuguese legal framework that regulates short-term tourist rentals, such as apartments, villas, or guesthouses rented through platforms like Airbnb, Booking.com, or directly to visitors.
Registering your property as AL allows you to legally rent your property to tourists and generate income while complying with Portuguese regulations.
Step 1: Check If Your Property Is Eligible for AL
Before starting the registration process, confirm that your property is eligible for Alojamento Local.
Requirements typically include:
The property must be legally registered for residential use
It must comply with safety and habitability standards
Some municipalities may have restrictions or containment zones
In condominiums, the building regulations must not prohibit AL
Since recent legal changes allow condominiums more influence, it is advisable to verify condominium rules before proceeding.
Step 2: Obtain a Portuguese Tax Number (NIF)
To operate an AL property, you must have a Portuguese Tax Identification Number (NIF).
You can obtain a NIF:
At a Portuguese Tax Office (Finanças)
Through a fiscal representative
Via specialized legal or relocation services
This number is required to register your activity and declare rental income.
Step 3: Open Activity with the Portuguese Tax Authority
The next step is to open a business activity with Finanças.
Most AL operators register under:
CAE 55201 – Alojamento Mobilado para Turistas
(Furnished accommodation for tourists)
This step officially allows you to issue invoices and declare rental income.
You can complete this step:
Online through the Finanças Portal
With the help of an accountant
Step 4: Register the Property on the RNAL Platform
All Alojamento Local properties must be registered in the RNAL – Registo Nacional de Alojamento Local.
Registration is done through the Balcão do Empreendedor portal.
You will need to submit:
Property identification details
Owner information
Capacity of the accommodation
Emergency contact information
Liability declaration confirming compliance with regulations
Once submitted, the system issues an AL registration number, which you must display in all advertisements.
Step 5: Ensure Safety Requirements Are Met
Portuguese law requires AL properties to meet basic safety standards.
These include:
Fire extinguisher
Fire blanket
First aid kit
Emergency contact information
Evacuation instructions
Properties must also have adequate ventilation, lighting, and sanitary conditions.
Municipalities may perform inspections to verify compliance.
Step 6: Obtain Mandatory Liability Insurance
AL operators must hold civil liability insurance covering damages to guests.
Typical coverage:
Minimum coverage usually starts around €75,000
This insurance protects both guests and property owners in case of accidents.
Step 7: Understand other legal obligations for AL in Portugal
Many new hosts believe that obtaining an AL licence is the final step. In reality, registering the property is only the beginning. Once you start receiving guests, you may also need to comply with:
SIBA / AIMA guest reporting
INE monthly accommodation statistics
Municipal tourist tax reporting
Invoicing obligations
Mandatory insurance requirements
What is SIBA ?
SIBA is the guest reporting system used to communicate foreign guest information to AIMA. Most AL operators in Portugal are legally required to submit guest data within 3 working days of arrival.

Step 8: Comply With Ongoing Obligations
After registration, AL operators must comply with ongoing rules.
These include:
Issuing invoices or receipts for guests
Declaring income to Portuguese tax authorities
Displaying the AL registration number in advertisements
Maintaining safety equipment
Complying with municipal regulations
Failure to comply may result in fines or suspension of the AL license.
How Long Does It Take to Register an AL Property?
In many cases, the AL registration process is fast.
Once submitted online, the registration number can be issued immediately, allowing you to start operating.
However, municipalities may later inspect the property to verify compliance.
Final Thoughts: Is Registering an AL Property in Portugal Worth It?
Despite regulatory changes, Alojamento Local remains a profitable investment opportunity in Portugal, especially in high-tourism regions.
By following the proper registration steps and maintaining compliance, property owners can legally operate short-term rentals and generate reliable income.
If you're planning to enter Portugal’s short-term rental market, understanding the AL registration process is the first step toward success.
