Register your AL step by step: the updated RNAL guide for 2026

The Registo Nacional de Alojamento Local — the RNAL — is the mandatory starting point for any short-term rental operation in Portugal. No registration, no registration number. No registration number, no legal listing on the platforms. It really is that straightforward, and that serious.

This guide walks through the registration process in sequence, so you know exactly what to do, in what order, and what to have ready before you start.

What the RNAL is and why it matters

The RNAL is the national database managed by Turismo de Portugal where every alojamento local must be enrolled. The number that comes out of that process — your número RNAL — is the unique identifier for your property and must appear on every listing you publish, whether on Airbnb, Booking.com, or any other platform.

This isn't bureaucracy for its own sake. The RNAL number is proof — to the platforms and to the authorities — that your accommodation meets the legal requirements. Platforms are required to verify and display that number, and to remove listings that don't show it.

Who needs to register

Anyone — individual or company — operating a property as alojamento local in Portugal needs to be on the RNAL. That includes:

• Owners who manage their own property directly
• Holders of a right of use (for example, usufructuaries or tenants with the owner's permission)
• Management companies operating on behalf of third-party owners

If you manage properties for other owners, the registration is made in the name of the person who holds the right to operate — not necessarily in your name as the manager.

Documents to gather first

Before you open the portal, it's worth having everything ready. The process moves much faster when you're not stopping to hunt for paperwork.

Core documents

• Applicant identification — citizen card or passport (for individuals); company certificate (certidão permanente) for legal entities
• Active NIF in Portugal
• Caderneta predial urbana for the property (or the matricial article reference)
• Authorisation of use (autorização de utilização) for residential purposes — or an equivalent document confirming the property's habitational suitability

Additional documents depending on your situation

• If the applicant is not the owner: a document proving the right to operate (tenancy agreement with a permissive clause, power of attorney, etc.)
• For standalone houses (moradias): a floor plan may be requested
• For hostel-type establishments or properties with specific characteristics: additional safety and accessibility documentation

Practical note: The caderneta predial is available free of charge on the Portal das Finanças, under the property section. The autorização de utilização is normally held at the câmara municipal — if the building is old, you may need to request a certified copy.

The registration process, step by step

1. Go to the Balcão Único Eletrónico

Registration is done online through the Balcão Único Eletrónico (BUE) at balcaounico.pt. You'll need to authenticate with your Chave Móvel Digital or your Citizen Card with an active PIN.

2. Select the type of establishment

The RNAL distinguishes several AL categories:

• Moradia — a standalone, single-family property
• Apartamento — an autonomous fraction within a building
• Estabelecimento de hospedagem — includes hostels and other typologies
• Quartos — rooms rented within the operator's own primary residence

Choosing the right category matters: requirements and maximum capacity rules vary depending on the type.

3. Complete the prior communication form

In most cases, AL registration works on a mera comunicação prévia basis — meaning you don't wait for approval. You notify, and the registration becomes active immediately (except in exceptional situations that may require additional review).

In the form you'll provide:

• Exact property location (full address and matricial reference)
• AL category
• Maximum capacity (number of guests)
• Details of the person holding the operating right

4. Submit and save your confirmation

After submission, you'll receive a confirmation document containing your assigned RNAL number. Keep this document — you'll need it to set up your listings on the platforms and for any future correspondence with the authorities.

5. Add your RNAL number to your listings

This step is immediate and mandatory. The main platforms have a dedicated field for the registration number — fill it in before activating your listing. Having the number registered isn't enough; it has to be visible.

Situations that can complicate the process

Property in a condominium

If your AL is in an apartment under horizontal property rules, the law allows other co-owners to object to AL activity in the building through a general meeting resolution. Before registering, it's worth checking whether the building's regulations or any previous resolutions impose restrictions.

Containment zones

Some municipalities have designated zonas de contenção where the creation of new AL registrations is suspended or restricted. Lisbon and Porto both have areas with specific limitations. Before proceeding with registration, confirm with the câmara municipal whether your property's location falls within any such restriction.

Property without an autorização de utilização

Very old buildings may not have a formal autorização de utilização on record. In these cases, it's possible to submit alternative documentation proving habitational suitability — but the process can take longer. Contact the câmara municipal to find the fastest route.

Keeping your registration up to date

Registration isn't a one-time act. Certain changes require an update:

• Change in maximum capacity
• Change of the person holding the operating right
• Change of category (for example, from apartment to hostel)
• Cessation of activity — closing your AL must be communicated to cancel the registration

An outdated registration can cause problems during inspections and, in some cases, lead to penalties. The principle is simple: whenever something changes in your AL that's relevant to the registration, notify the authorities.

Renewals and periodic checks

The RNAL doesn't generally require automatic annual renewal in the way a fixed-term licence would. That said, authorities can request compliance checks, and câmaras municipais have inspection powers. Keeping your supporting documents organised and accessible — caderneta predial, autorização de utilização, registration confirmation — saves a lot of time if you're ever contacted.

What's changing in 2026

The regulatory framework for alojamento local has been evolving. The obligations around displaying the RNAL number on digital listings have become stricter, with platforms being made jointly responsible for verifying registrations. This means an invalid, outdated, or missing RNAL number can result in your listing being removed by the platform itself — without prior warning.

The regulatory direction is towards greater integration between the RNAL, the platforms, and the tax authorities. Having your registration in order isn't just a formality: it's the foundation everything else rests on.

When you have everything prepared, the registration process is faster than it looks. Most complications come from missing documents or uncertainty about the right category — two problems that are easily solved before you open the form.
