An Alojamento Local license is Portugal’s legal authorization to rent a property to tourists on a short-term basis, obtained by filing a prior notification (comunicação prévia) through the national Balcão Único Eletrónico portal. The framework sits in Decree-Law 128/2014, was tightened by Law 56/2023 (the Mais Habitação program), and was substantially loosened again by Decree-Law 76/2024. What that back-and-forth means in practice: the national rules are workable, but individual municipalities now decide much of what applies in your neighborhood.
Before touching the application, you need to know which of four categories your property falls into, because the rules branch from there.
The Four Property Categories
- Apartment (Apartamento): A self-contained unit inside a larger building. The most common category in Lisbon and Porto, and the one most affected by condominium rules.
- House (Moradia): A standalone, single-family home. Exempt from the mandatory AL identification plaque.
- Guesthouse or Hostel (Estabelecimento de Hospedagem): A property with multiple guest rooms and shared common areas. Hostels face stricter condominium approval rules.
- Room (Quarto): Up to three private rooms rented within the owner’s own residence.
The category you select drives capacity limits, signage rules, and how much scrutiny you face from other owners in a building.
Physical and Safety Requirements
Every AL property except hostels caps at nine rooms and thirty guests. A single owner also cannot operate more than nine apartments as AL in one building if those units would make up more than 75% of the building’s total, and that count includes units held under a spouse, children, parents, or related companies.1Turismo de Portugal. Decree-Law no. 128/2014
Each accommodation unit needs a window or balcony opening directly outside for light and ventilation.1Turismo de Portugal. Decree-Law no. 128/2014 The property must meet basic hygiene standards at all times.
For safety, properties hosting ten or fewer guests need a portable fire extinguisher and fire blanket accessible to guests, a stocked first aid kit, and a visible posting of the national emergency number 112.1Turismo de Portugal. Decree-Law no. 128/2014 Larger properties fall under broader fire safety regulations that often require additional equipment and a fire safety assessment. Inspectors check for expired extinguishers, depleted first aid supplies, and missing signage, so this equipment has to stay current.
Civil liability insurance is required, with a minimum coverage of €75,000 per claim. Older guides sometimes quote higher figures; the legal floor set by the decree is €75,000.
Documents You Need
The comunicação prévia application under Article 6 of Decree-Law 128/2014 asks for:2Diário da República. Decreto-Lei 128/2014 de 29 de Agosto
- A copy of your ID if you’re applying as an individual, or your commercial registry code if applying as a company.
- A signed statement of responsibility (Termo de Responsabilidade) confirming the property meets legal requirements for accommodation services.
- The building tax record (Caderneta Predial Urbana) if you own the property.
- If you’re a tenant, the lease contract along with authenticated landlord authorization if the lease itself doesn’t already permit short-term subletting.
- A copy of your tax activity declaration (início or alteração de atividade) filed with the Tax and Customs Authority, using the correct accommodation subclass (55201 or 55204).
You’ll also need a Portuguese Tax Identification Number (NIF), which foreign nationals obtain through the Tax and Customs Authority.3gov.pt. How to Request NIF and NISS for Foreign Citizens in Portugal The form itself asks for the property address, its capacity in rooms, beds, and guests, your planned opening date, and an emergency contact.
How Registration Works
You submit everything electronically through the Balcão Único Eletrónico, and the system issues a registration number on submission.2Diário da República. Decreto-Lei 128/2014 de 29 de Agosto That number is legally required on every listing you publish, on Airbnb, Booking.com, or anywhere else.
Once you submit, the local Municipal Council has a window to object or inspect. Under Decree-Law 76/2024, that window runs 60 days for standard properties, or 90 days if the property sits in a designated containment zone. If nothing comes back within that period, the license is deemed approved. Many municipalities still inspect in practice, but silence is now approval, not rejection.
Operating without a valid registration exposes you to fines, with different penalty scales for individuals and companies.
If Your Property Is an Apartment: Condominium Rules
For apartments in multi-unit buildings, the other owners have a voice in whether an AL can operate. This is where recent law has changed the most, and where applicants most often get stopped.
Under Decree-Law 76/2024, a condominium association can oppose your AL, but the opposition must be backed by evidence of repeated disturbances significantly disrupting normal use of the building, and it must be approved by more than half of the co-ownership shares. If the condominium’s existing regulations already ban AL activity, that ban stands and can block your application outright.
When a valid opposition is filed, the matter moves to the municipality. A municipal AL representative has 60 days to try to mediate. The final call belongs to the municipality, not the condominium. A cancellation order stops operations and can last up to five years.
A condominium can also change its regulations to ban AL going forward, but that requires a two-thirds majority of ownership shares, a higher bar than opposing a single unit. If you’re buying an apartment specifically to run as AL, read the condominium regulations before you close.
Municipal Containment Zones
Municipalities can designate “áreas de contenção” in neighborhoods where short-term rental density is pressuring the permanent housing supply. Inside those zones, local governments can suspend new AL registrations or impose extra conditions. Some cities also define “sustainable growth zones” where new licenses are allowed but come with requirements like energy efficiency standards or primary residence quotas.
Law 56/2023 had frozen new AL apartment registrations nationwide.4Diário da República. Law 56/2023 Decree-Law 76/2024 lifted that general suspension, so it’s again possible to apply anywhere in Portugal. Municipalities keep full authority to restrict registrations within their own containment areas, which is why Lisbon and Porto still have neighborhoods where new applications face limits while smaller cities may have none.
Containment zones can also restrict license transfers on sale. The general rule under Decree-Law 76/2024 is that AL licenses survive a sale and pass to the new owner, but municipalities can carve out exceptions in containment areas, such as blocking conversion of a property that was used for long-term rental in the previous two years. These carve-outs typically exclude inheritance, divorce, and family transfers.
Before buying for AL use, check the specific rules for your target neighborhood through the local câmara municipal.
Taxes You Will Owe
AL income is taxable, and the structure depends on your residency and revenue.
Income Tax
Most individual operators fall under Category B of personal income tax (IRS) in the simplified regime. Your taxable base isn’t your actual profit; the tax authority applies a coefficient to gross revenue. For apartments and houses the coefficient is 0.35, so 35% of gross AL income is taxable. For a room rented inside your own home it drops to 0.15. Properties in designated containment zones face a higher coefficient of 0.50.
Portuguese residents then pay progressive rates from 13.25% to 48%, plus a solidarity surcharge at the top brackets. Non-residents pay a flat 25% on the taxable amount. The simplified regime is available while annual AL revenue stays below €200,000.
VAT
AL is subject to Value Added Tax (IVA). Turnover below €15,000 can qualify for the small-business exemption, which spares you from charging or remitting VAT.5gov.pt. Value Added Tax (VAT) in Portugal The exemption also requires that you don’t engage in import or export activity. Once revenue crosses the threshold, you register for VAT and apply the applicable rate.
Social Security
Operating AL as a self-employed person under Category B also triggers social security contributions on declared income. This surprises many foreign owners, particularly non-residents who don’t associate rental income with social insurance. Rates and exemption periods vary, and professional tax advice usually pays for itself here.
Ongoing Obligations After You’re Licensed
The license is the beginning of compliance, not the end.
Reporting Foreign Guests to AIMA
Portuguese immigration law requires you to report every foreign guest to the Agency for Integration, Migration and Asylum (AIMA) within three working days of arrival, through the SIBA platform.6AIMA. Comunicacao Duvidas Comuns The report includes full name, nationality, passport details, and stay dates. Departure information is due within three working days after checkout. Fines apply per guest for missed deadlines, so this belongs inside your check-in process, not batched later.
Complaints Book
Every AL property must keep a Complaints Book (Livro de Reclamações) in both physical and electronic form. The physical version stays on the premises and must be produced whenever a guest asks. The electronic version routes complaints through a government portal. Not having the book available on request is itself a violation.
Identification Plaque
Apartments, guesthouses, and rooms must display the official AL identification sign near the main entrance. Houses are exempt. The required size depends on placement: 10×10 cm if the entrance is inside the building, 20×20 cm if it faces the exterior.
Record Keeping
Guest records and financial documentation must be retained for several years to cover potential tax audits and immigration inquiries. Both AIMA and the Tax Authority can request historical records.
What Changed Under Decree-Law 76/2024
Many older guides still describe the stricter Mais Habitação rules. The changes most likely to affect your planning:
- Registrations no longer expire. Law 56/2023 had introduced a five-year validity period requiring periodic renewal; Decree-Law 76/2024 revoked it.
- Licenses transfer with the property. The Mais Habitação rule that automatically cancelled the license on sale is gone, though municipalities can restrict transfers in containment zones.
- The nationwide freeze on new apartment-category registrations is over. Applications are open again, subject to local rules.
- Condominium opposition now needs more than 50% of co-ownership shares (down from two-thirds), but must be supported by evidence of actual disturbances.
- The 15% annual extraordinary contribution created by Law 56/2023 was repealed retroactively to December 31, 2023.
The reversal doesn’t mean the environment is loose. It means control shifted from national blanket rules to municipal decisions. A city that wants to restrict AL in a specific neighborhood still has every tool to do it. The neighborhoods that welcome tourism-driven rentals are simply no longer blocked by a national freeze.
