Airbnb Rules Portugal: 2026 Guide to Laws and Regulations

Portugal Airbnb Compliance Checklist

• ☐ Register the Property as an AL (Alojamento Local)

  • Submit the prior notice (mera comunicação prévia) through the Balcão Único Eletrónico (BUE) portal before accepting any bookings.

  • Obtain the AL registration number issued by the Câmara Municipal; this number must appear on every listing and advertisement.

• ☐ Confirm Property Category and Capacity Limits

  • Verify whether the property qualifies as moradia, apartamento, estabelecimento de hospedagem, or quarto, under Decree-Law 128/2014 as amended by Law 56/2023.

  • Apartamento listings are capped at 9 guests and 3 rooms; confirm the property does not exceed these limits.

• ☐ Check Municipal Containment Zone Status

  • Contact the Câmara Municipal to confirm whether the property sits within a zona de contenção designated under Law 56/2023, effective November 7, 2023.

  • New apartamento licenses are suspended in containment zones; moradia licenses are unaffected.

• ☐ Verify Condominium Authorization

  • Obtain written approval from the condominium assembly if the property is in a horizontal property regime, a simple majority vote (more than 50%) can now block or suspend AL activity under Law 56/2023.

• ☐ Install Mandatory Safety Equipment

  • Fit a working fire extinguisher and fire blanket in the kitchen.

  • Install a first aid kit and post emergency contact numbers visibly in the property.

• ☐ Display the AL Identification Plaque

  • Mount the standardized AL plaque at the property entrance, as required under Decree-Law 128/2014. The plaque format is specified by Portaria 517/2008.

• ☐ Collect and Remit Tourist Tax (Taxa de Turismo)

  • Check the applicable rate for the municipality. Lisbon charges €2.00 per guest per night (capped at 7 nights); Porto charges €3.00 per guest per night.

  • Remit collected amounts to the Câmara Municipal on the schedule they specify, typically quarterly.

• ☐ Register for IRS/IRC and VAT Obligations

  • Register AL income under Category B (IRS) if operating as an individual, or under IRC if operating through a company.

  • If annual turnover exceeds €14,500 (the 2024 simplified regime threshold), assess VAT obligations with a tax adviser.

1. Regulatory Overview

Short-term rental activity in Portugal operates under three compliance layers: national legislation, municipal ordinances, and platform-specific obligations. All three apply simultaneously, and a host cannot satisfy one while ignoring the others.

The primary national framework is Decree-Law No. 128/2014 as substantially amended by Decree-Law No. 63/2015 and later revised under Law No. 62/2018, which introduced the concept of containment zones and gave municipalities authority to restrict or suspend new registrations in high-pressure areas.

The 2023 housing reform package, enacted under Law No. 56/2023 (effective November 7, 2023), further tightened the framework by suspending new alojamento local licenses in most urban parishes and granting municipalities the power to revoke existing licenses under defined conditions.

Portuguese law defines a short-term rental, known as alojamento local, as the provision of temporary accommodation services to tourists for periods of fewer than 30 consecutive days in exchange for payment, where the property is not classified as a hotel or tourist development.

Two main bodies enforce Portugal's rules. Turismo de Portugal, I.P. (Turismo de Portugal) manages the national alojamento local register, known as the RNAL.

But it's the local municipal councils (câmaras municipais) that really hold the power, overseeing everything from zoning and containment zones to yanking your license.

(And don't forget, Lisbon and Porto have their own dedicated inspection squads.) The takeaway? Your city council calls the shots.

2. Who Needs an Alojamento Local Registration

Every property rented to tourists for periods shorter than 30 consecutive days in Portugal requires an Alojamento Local (AL) registration under Decree-Law No. 128/2014, as substantially amended by Law No. 56/2023, effective November 1, 2023.

There are no exemptions for low-frequency rentals or properties listed on a single platform only.

National AL Registry

The national framework applies uniformly across Portugal. Registration is administered by the host's municipal authority (câmara municipal), and the resulting license number must appear on every listing across Airbnb, Vrbo, and Booking.com.

Platforms operating in Portugal are legally required to verify that a valid AL number exists before publishing a listing.

• Who Must Register: Any property owner or long-term tenant (with landlord authorization) renting to tourists for stays under 30 days.

• Application Submission: Filed through the Balcão Único Eletrónico (BUE) portal at ePortugal.gov.pt using a valid NIF (tax identification number) and authentication credentials.

• Property Documentation: Caderneta predial (land registry extract), proof of habitation license or equivalent declaration for older properties, and property floor plans.

• Fees: There's no single national application fee. A standard AL application in Lisbon will set you back a hefty €533.60 as of 2025, while just a few hours north in Porto, the same license costs only €310.00. Each municipality sets its own rates by local ordinance, so you'll have to check with your local câmara. Basically, it's a patchwork.

• Processing Time: Municipalities have 20 days to respond. Silence constitutes tacit approval under the administrative code.

Law No. 56/2023 introduced a primary-residence distinction. Properties registered as habitação própria e permanente (owner's primary residence) retain registration rights regardless of municipal moratoriums.

Properties that are not the owner's primary residence are subject to municipal suspension or non-renewal decisions, particularly in Lisboa and Porto.

The 183-day threshold used in tax residency determinations does not directly govern AL classification; primary residence status is assessed by municipal records and fiscal domicile, not rental-night counts.

3. How to Stay Compliant Before Buying or Listing a Property

Portugal has no national prohibited buildings list comparable to New York's Class A/B dwelling system. Property eligibility for short-term rental registration is governed by a different set of constraints, and missing any one of these blocks registration entirely.

Condominium and Horizontal Property Rules

Under Decree-Law No. 128/2014 of August 29, 2014, as amended by Law No. 62/2018 of August 22, 2018, condominium assemblies may vote to restrict or prohibit short-term rental activity. A resolution requires approval by more than half of the percentage value of the building.

Hosts who register an Alojamento Local (AL) license after a valid restriction resolution has passed are operating illegally, regardless of whether the câmara municipal accepted the registration.

• Condo Restrictions and HOA Bylaws: New registrations in restricted buildings are blocked under Article 9-A of Law No. Private condominium regulations will impose additional restrictions beyond the statutory minimum. Review the título constitutivo before purchasing.

• Zoning Ordinances: Municipal master plans (Planos Diretores Municipais) in Lisbon and Porto designate containment zones where new AL licenses are suspended; confirm eligibility with the local câmara before acquisition.

Containment Zones and Suspension Areas

Lisbon's Municipal Regulation No. 254/2019 suspended new AL registrations for residential-use units in freguesias, including Santa Maria Maior and Misericórdia. Porto issued a comparable suspension under Deliberation No.

Properties in these zones cannot receive new residential AL licenses regardless of physical condition or ownership structure. Commercial-use properties classified under the Código do IMI as non-residential may be exempt; verify with the câmara's urbanismo department.

4. Day-to-Day Operating Rules for Active Hosts

Guest Limits

Decreto-Lei n.º 128/2014, as amended by Lei n.º 62/2018 (effective November 21, 2018), sets the baseline capacity rules for alojamento local (AL) properties. Capacity is calculated by bedroom count, not by property size.

• Maximum of 9 paying guests per AL apartment or villa: Properties with more than 3 bedrooms may accommodate up to 3 guests per bedroom, subject to the 9-guest ceiling. Hostel-category AL units operate under separate dormitory capacity rules.

• 2-guest default per bedroom: Properties with 3 or fewer bedrooms are limited to 2 guests per room unless the local câmara municipal has approved a higher allocation in writing.

Exception: Rural tourism units (turismo de habitação and turismo rural) are governed by Decreto-Lei n.º 186/2015 and carry different capacity formulas. If the property holds a rural classification, the AL guest limits above do not apply.

Minimum-Stay Thresholds

Portugal's national framework imposes no statutory minimum stay for AL properties. Municipal regulations may differ.

Lisbon's Regulamento Municipal de Alojamento Local (Deliberação n.º 463/CM/2023) does not specify a minimum-stay floor, but condominium bylaws can effectively impose one by restricting entry-day noise or check-in hours.

Host Presence Requirements

No host-presence requirement exists under Decreto-Lei n. Hosts must, however, designate a responsible manager (responsável) reachable 24 hours a day. That contact must be registered with the Registo Nacional de Alojamento Local (RNAL) and displayed on all booking platform listings.

Note (Bill 155/XV): Keep an eye on this one. The proposed Proposta de Lei n.º 155/XV would force the designated responsável to respond to any municipal complaint, like a neighbor's 2 AM noise complaint, within just one hour.

That's a tight window. As of May 2026, the bill is still stuck in parliamentary review, so it's not law yet.

5. Tax Obligations

National Taxes

Short-term rental income in Portugal falls under Category F (rental income) or Category B (business income) of the Personal Income Tax Code (Código do IRS), depending on how the host is registered.

Hosts operating under the simplified regime (regime simplificado) are taxed on 35% of gross rental receipts as of the 2024 tax year, with the remaining 65% treated as deductible costs without documentation.

Total Combined Tax Rate: Don't expect a simple tax answer. A Lisbon-based host on the simplified IRS regime pays a 28% flat rate on just 35% of their gross income, but then they've also got to add a €4.00 per-guest, per-night tourist tax and factor in their local IMI rates.

Your final tax burden is a moving target. It all depends on where you are and how you're registered.

Platform Collection Requirements

Airbnb collects and remits tourist tax on behalf of hosts in Lisbon, Porto, and several other municipalities under agreements with local councils.

Hosts must verify with their specific municipality whether platform remittance covers their obligation in municipalities without a platform agreement; the host collects and remits the tax directly. VAT (IVA) at 6% applies to accommodation services when the host is registered as a sole trader

6. Safety, Guest Information, and Operating Rules Hosts Must Follow

Mandatory Safety Equipment

• Smoke Detectors: Operational smoke detectors required in every bedroom and hallway, per the Regulamento Geral das Edificações Urbanas (RGEU) and Decreto-Lei n.º 220/2008 governing building fire safety.

• Carbon Monoxide Detectors: Required in any unit with gas appliances or enclosed combustion sources.

• Fire Extinguisher: At least one certified extinguisher accessible on each floor of the property.

• Emergency Exits: All exit routes must remain unobstructed and clearly marked.

Building Compliance

• Habitability Certificate: The property must hold a valid licença de utilização confirming residential use, issued by the local Câmara Municipal.

• Structural Condition: No active urban rehabilitation orders (obras de reabilitação obrigatórias) may be outstanding against the property.

• Capacity Limits: Guest numbers cannot exceed the occupancy declared in the AL registration, which is capped at 9 guests under standard AL rules.

7. Booking Platform Requirements

Portugal's Lei n.º 56/2023, effective October 1, 2023, established direct obligations for digital platforms operating in the short-term rental market. This is one of the more significant shifts in how Airbnb rules in Portugal apply beyond individual hosts.

Verification Requirements

• Registration Number Display: Platforms must require hosts to provide a valid Alojamento Local (AL) registration number before a listing goes live. Listings without a current RNAL number cannot be accepted.

• Active Status Checks: Platforms are required to verify that registration numbers correspond to active, non-suspended entries in the national registry maintained by the Agência para a Modernização Administrativa (AMA).

Reporting Requirements

• Annual Data Submission: Under Lei n.º 56/2023, platforms must submit annual activity reports to the Turismo de Portugal, covering transaction volumes and host registration data per listing.

• Non-Compliance Exposure: Platforms that knowingly list unregistered properties face fines ranging from €4,000 to €40,000 per infraction under the same statute.

8. Local Restrictions: Where Airbnb Rules Can Change by City or Neighborhood

Portugal does not have a national statute that prohibits advertising a short-term rental before a booking transaction occurs. The Lei n.º 62/2018 framework governs registration and operation of alojamento local units, but it imposes no pre-advertising prohibition equivalent to, for example, New York City's Local Law 18 trigger.

General consumer-protection rules under the Código do Consumidor apply to all commercial advertising equally and are not STR-specific restrictions.

Municipal câmaras in Lisbon and Porto have enacted containment zones and suspension periods under Article 15.º-M of Lei n.º 62/2018, but those measures restrict new registrations, not the act of advertising itself.

No Portuguese municipality has enacted a law making it illegal to list or advertise an STR unit before a booking transaction.

9. Enforcement and Penalties

Civil Penalties

The legal ground keeps shifting. Portugal's core rules are anchored in Decree-Law No. 128/2014, but it's been significantly changed by Law No. 62/2018 (effective August 22, 2018) and, most recently, by the sweeping Law No. 56/2023 (effective September 13, 2023).

Both the national Turismo de Portugal, I.P. and local municipal authorities share enforcement duties. But make no mistake: the 2023 amendments gave municipalities way more teeth, including the direct power to suspend licenses for repeated noise violations. They're the ones you really need to watch.

• Operating without a valid RNAL registration: €4,000 to €40,000 for individuals; €8,000 to €80,000 for companies (Article 50, Decree-Law No.

• Failure to display registration number in listings: €500 to €5,000 per violation

• Exceeding approved guest capacity: €2,000 to €20,000 per infraction

• Operating in a designated containment zone without municipal exemption: €4,000 to €40,000

• Non-compliance with safety requirements (fire, insurance): €500 to €5,000

Enforcement Mechanisms

• Platform data sharing: Airbnb, Booking.com, and Vrbo are required to report host data to Turismo de Portugal under Law No.

• Complaint-driven inspections: Neighbor or condominium complaints trigger municipal inspections, which have increased 34% in Lisbon since 2023

• Proactive digital monitoring: Turismo de Portugal cross-references active listings against the RNAL public register to identify unregistered properties

• Tax authority coordination: The Autoridade Tributária e Aduaneira (AT) flags hosts with rental income not matched to a registered AL number

Registration Denial and Revocation

Municipalities may deny or revoke AL registration on the following grounds:

Property located in a containment zone with no approved exemption

10. Special Considerations

Rent-Controlled and Social Housing Units

Properties subject to rent control under the Novo Regime do Arrendamento Urbano (Law 6/2006, as amended) face additional constraints.

Landlords in rent-controlled tenancies cannot convert occupied units to short-term use without terminating the existing lease through legally prescribed procedures. Attempting to do so exposes the landlord to tenant claims under Article 1083 of the Civil Code and potential reversal of any AL registration obtained for that unit.

• Conflict point: Existing long-term lease agreements that predate the AL application invalidate the registration.

• Conflict point: Municipalities designated as Áreas de Contenção under Decree-Law 76/2024 (effective July 1, 2024) may impose additional restrictions on converting previously rented residential units.

Condominium and Homeowner Association Rules

Under Article 1422-A of the Civil Code, condominium assemblies may prohibit or restrict AL activity by a two-thirds majority vote of the total share of the building. This is one of the most commonly overlooked restrictions in Portuguese STR compliance.

A valid AL license from the municipality does not override a condominium prohibition. Hosts operating in defiance of a condominium ban face suspension of their AL registration under Decree-Law 128/2014, Article 9-A.

• Conflict point: Condominium minutes approving a ban must be formally registered, but enforcement timelines vary by municipality.

• Conflict point: Buildings with no registered condominium (common in rural areas) have no mechanism to impose this ban, so the restriction does not apply there.

Historic and Heritage Properties

Properties classified under the Lei de Bases do Património Cultural (Law 107/2001) require prior authorization from the Direção-Geral do Património Cultural (DGPC) for any use change, including STR activity.

Unauthorized short-term rental use in a classified building can result in fines between €2,493.99 and €3,740.98 under Article 75 of Law 107/2001, independent of any AL-specific penalties.

11. Exemptions

Not all short-term accommodation arrangements in Portugal fall under the Alojamento Local framework governed by Decree-Law No. 128/2014 and its subsequent amendments.

• Stays of 30 consecutive days or more: These are classified as residential tenancies under the Portuguese Urban Lease Regime (Lei n.º 6/2006, as amended) and are not subject to AL registration requirements or restrictions on short-term rental activity.

• Licensed hotels, aparthotels, and tourist resorts: These operate under the tourism establishment regime regulated by Decree-Law No. 39/2008 and are governed by Turismo de Portugal, not AL licensing rules.

• Bed and breakfast establishments (Turismo de Habitação and Turismo Rural): Rural and heritage tourism properties registered under their own classification categories follow separate licensing and capacity rules distinct from urban AL requirements.

• Student housing and university residences: Accommodation provided under formal academic agreements is exempt from AL obligations entirely.

12. Legislative Developments

Decreto-Lei 76/2024 (enacted Reform)

The most recent substantive change to Portugal's short-term rental framework came through Decreto-Lei 76/2024, published in October 2024.

This decree revised the Alojamento Local regime established under Decreto-Lei 128/2014, reintroducing condominium veto rights and tightening municipal quota controls in high-pressure areas. As of May 2026, this decree is fully enacted and in force.

Municipal Containment Zone Reviews (2025-2026)

Several municipalities, including Lisboa and Porto, initiated government-published reviews of their designated containment zones in 2025, with updated zone maps expected by late 2026. These reviews may affect:

• New License Eligibility: Properties in reclassified containment zones face automatic suspension of new AL registrations.

• Quota Adjustments: Municipal councils may reduce the 75% AL saturation ceiling further in specific parishes.

No national legislative bill beyond Decreto-Lei 76/2024 is currently pending as of May 2026.
