Short-term rental activity in Porto operates under three distinct compliance layers: national Portuguese law, municipal regulations issued by the Câmara Municipal do Porto, and sector-specific rules administered through the national tourism authority.
Hosts must satisfy requirements at all three levels simultaneously. Failing any single layer exposes the operator to fines, license suspension, or forced delisting from booking platforms.
The primary governing statute is Decreto-Lei n.º 128/2014, de 29 de agosto, which established the national legal framework for alojamento local (local accommodation) and has been substantively amended by Decreto-Lei n.º 63/2015 and, most significantly, by Lei n.º 62/2018, de 22 de agosto.
Porto's municipal layer adds further restrictions through deliberations issued under Article 15-A of Lei n.º 62/2018, which grants municipalities authority to cap licenses in designated containment zones.
Under Portuguese law, a short-term rental is defined as any furnished residential unit let to guests for periods fewer than 30 consecutive nights for remuneration. Properties let for 30 nights or more fall under standard residential tenancy law and exit the alojamento local regulatory framework entirely.
The national enforcement and registration authority is the Turismo de Portugal, I.P., which maintains the national alojamento local register.
At the municipal level, the Câmara Municipal do Porto (CMP) holds authority over zoning restrictions, containment area designations, and local license suspensions under the powers granted by Lei n.Lei n.º 62/2018
Porto does not operate a standalone municipal STR registration system equivalent to New York's Local Law 18 or Lisbon's parish-level quotas. Registration for short-term rental activity in Porto is governed by the national Alojamento Local framework under Decree-Law No. 128/2014, as substantially amended by Law No. 56/2023, effective November 1, 2023.
There is no separate city-level registry to file with beyond that national system.
Effective date: The current consolidated regime took effect November 1, 2023, following Law No. 56/2023. Hosts operating before that date were required to review and update their registrations to confirm continued eligibility under the revised criteria.
All hosts, including those listing on Airbnb, Vrbo, or Booking.com, must hold a valid Alojamento Local registration number issued by the Balcão Único Eletrónico (BUE) via the Portal do Cidadão. Platforms are required under Law No. 56/2023 to verify that active listings display a valid registration number.
Application requirements include:
Property Title Proof: Hosts must submit documentation confirming ownership or legal authority to operate the unit as AL.
Floor Plan: A scaled floor plan identifying rooms, exits, and sleeping capacity.
Condominium Authorization: Where applicable, written consent from the condominium assembly, which Law No. 56/2023 now requires by majority vote (more than half of the fraction permilage).
Safety Compliance: Evidence of operational fire extinguisher, smoke detector, and first-aid kit on premises.
Registration fees are set nationally at approximately €150 per unit, though municipal processing surcharges may apply. Porto imposes no primary-residence day threshold equivalent to the 183-day rules seen in other jurisdictions; instead, capacity and zoning restrictions govern eligibility.
Property eligibility under Portuguese short-term rental law is governed by a combination of national legislation, condominium rules, and municipal zoning decisions.
Portugal's entire alojamento local framework really boils down to one core law: Decreto-Lei n.º 128/2014, updated by Lei n.56/2023. It’s pretty specific.
The law allows for registrations of apartments, detached houses (moradias), and certain lodging establishments (estabelecimentos de hospedagem).
Hostels are a whole different beast, treated as a separate sub-category with their own rules, like requiring a minimum of 4 beds per dormitory, so don't just assume your property is eligible.
Apartments: Subject to condominium veto rights introduced by Lei n. 56/2023. An owners' assembly may suspend or prohibit short-term rental activity by a majority vote of more than half the total permilage of the building.
Detached Houses: Not subject to condominium veto. Eligibility turns on zoning classification and municipal planning instruments (Plano Diretor Municipal).
Commercial Premises: Ineligible for alojamento local registration unless the space meets residential habitability standards under the Regulamento Geral das Edificações Urbanas (RGEU).
A condominium can now vote to restrict short-term rentals, a major change under Lei n.56/2023. It's a serious move, requiring a resolution passed by at least two-thirds of the building's co-owners to go into effect.
So what happens? Existing licenses aren't automatically revoked, but they can't be transferred or renewed once the restriction is active. For new hosts, the door slams shut immediately. You've got to verify the building's status before registering anything.
Under Decreto-Lei n.º 128/2014, as amended by Lei n.º 62/2018 (effective November 1, 2018), alojamento local units in Portugal are subject to capacity ceilings tied to the number of rooms and bed configurations declared at registration.
For standard apartments (apartamento category), the legal maximum is 9 guests per unit. For rooms let within the host's primary residence (quartos category), the ceiling is 3 rooms with no more than 6 guests across those rooms combined.
Hosts must post the maximum capacity figure inside the unit; operating above the registered capacity is a violation subject to fines under the general AL infraction framework.
Portugal's national framework does not impose a statutory minimum-stay floor on AL units. Porto's municipal regulations under the Regulamento Municipal de Alojamento Local de Porto (approved July 2021) do not add a minimum-night requirement either.
However, Porto's 2021 containment zones (áreas de contenção) prohibit the issuance of new AL licenses in designated historic parishes; they do not restrict nightly minimums for existing licensed properties.
No host-presence requirement applies to apartamento-category AL units in Porto. Hosts must designate a responsible manager (responsável pela exploração) reachable by guests and authorities at all times, with contact details registered with the Câmara Municipal do Porto. That person does not need to be on-site during stays.
Note: Proposed national legislation (Proposta de Lei n.º 75/XV) would grant municipalities expanded authority to impose nightly caps and seasonal operating restrictions. Porto has not enacted implementing measures as of May 2026, but hosts should monitor Câmara Municipal announcements for any 2026 ordinances.
Portugal applies Value Added Tax (IVA) under the Código do Imposto sobre o Valor Acrescentado (CIVA). Short-term rental income under alojamento local is subject to IVA at the standard rate where hosts exceed the annual exemption threshold.
Tax Type | Rate | Description |
|---|---|---|
IVA (Standard Rate) | 23% | Applies to AL rental income where annual turnover exceeds €14,500 |
IVA (Exemption Threshold) | 0% | Hosts below €14,500 annual turnover claim exemption under Article 53 of CIVA |
IRS / IRC (Income Tax) | 25% (flat, non-residents) | Withholding rate on gross AL rental income for non-resident hosts; residents taxed under progressive IRS brackets |
Tax Type | Rate | Description |
|---|---|---|
Derrama Municipal | Up to 1.5% | Municipal surcharge on taxable corporate income; applies to hosts operating as companies |
Tourist Tax (Taxa Turística) | €2.00 per person/night | Porto's flat levy per adult guest, capped at 7 consecutive nights; effective under Porto Municipal Regulation No. 516/2018 |
Total Combined Tax Rate (non-resident individual host, above VAT threshold): 23% IVA + 25% IRS withholding + €2.00 per guest/night tourist tax.
Airbnb collects and remits the €2.00 tourist tax directly to Câmara Municipal do Porto on behalf of hosts. Hosts using Booking.com or VRBO must collect and remit the tourist tax independently, filing monthly with the municipal treasury.
Hosts registered under IRS Category B must submit an annual Declaração de IRS by June 30 of the following tax year. VAT returns are filed quarterly for hosts above the €14,500 threshold.
Failure to register for IVA carries penalties from €300 under Article 116 of the Regime Geral das Infrações Tributárias (RGIT).
Porto's short-term rental safety requirements are governed by the Regime Jurídico da Instalação, Exploração e Funcionamento dos Empreendimentos Turísticos (Decreto-Lei n.º 128/2014, as amended by Decreto-Lei n.º 62/2018, effective June 22, 2018).
All AL (Alojamento Local) units must maintain the following equipment in working condition at all times:
Fire Extinguisher: At least one portable extinguisher per floor, accessible to guests.
First Aid Kit: A stocked kit is present on the premises and disclosed to guests upon check-in.
Emergency Contacts: Posted notice listing national emergency number (112) and the property owner's or manager's direct contact.
Gas Safety: Properties with gas installations require a valid inspection certificate from a licensed technician.
Habitation License: The unit must hold a valid licença de utilização for residential use, confirmed by the Câmara Municipal do Porto.
Structural Condition: No active condemnation orders or unresolved building violations on record with the municipality.
Ventilation and Lighting: All sleeping areas must meet minimum natural light and ventilation standards under the Regulamento Geral das Edificações Urbanas (RGEU).
Registration Display: Under Decree-Law No. 128/2014 (as amended by Law No. 62/2018, effective September 4, 2018), platforms operating in Portugal must display the host's Número de Registo (AL registration number) on every listing.
Airbnb enforces this through its listing form, requiring hosts to enter a valid registration number before a Porto property can be published.
Listing Suspension: Platforms are required to remove or block listings that lack a valid AL number. Airbnb has applied this policy to Portuguese listings since 2019 following pressure from the Autoridade de Segurança Alimentar e Económica (ASAE).
Guest Data Submission: Platforms facilitating bookings in Portugal are subject to the same SEF/AIMA guest registration obligations that apply to hosts directly.
Failure to ensure guest data reaches the Serviço de Estrangeiros e Fronteiras (SEF) system exposes both host and platform to penalties under Law No.56/2023
Everything above, in the order you'll do it — who you deal with at each step and what it costs.
Portugal's Decree-Law No. 128/2014, as amended by Decree-Law No. 62/2018 (effective July 16, 2018), establishes a tiered fine structure administered by the Autoridade de Segurança Alimentar e Económica (ASAE) and municipal authorities. Penalties apply per violation, not per stay.
Operating without registration (AL license): €2,500 to €3,740 for individuals; €25,000 to €44,890 for companies
Failure to display registration number in listings: €250 to €3,740 per infraction
Non-compliance with safety requirements: €250 to €3,740 depending on severity
Exceeding licensed guest capacity: €500 to €3,740 per occurrence
ASAE and Porto's Câmara Municipal use several detection methods, none of which require a formal complaint to trigger an inspection.
Platform data requests: Portuguese authorities can require Airbnb, Booking.com, and Vrbo to disclose host and listing data under Law No.56/2023
Complaint-driven inspections: Neighbor or condominium complaints route directly to ASAE
Proactive monitoring: ASAE conducts periodic sweeps of online listings cross-referenced against the national AL registry
On-site inspections: Unannounced visits are permitted under Article 20 of Decree-Law No.128/2014
The Portal do Cidadão processes AL applications, but Porto's municipality holds the authority to deny or cancel registrations on the following grounds:
Condominium opposition: A majority vote by the building's owners' assembly blocks or revokes AL status under Article 4(4) of Decree-Law No.128/2014
Porto's municipal housing strategy, accelerated by theLei n.º 56/2023 (effective October 7, 2023), explicitly restricts short-term rental activity in properties subject to rent control or social housing programs.
Hosts who register an alojamento local in a rent-controlled unit face registration refusal and potential criminal liability for housing fraud under the Portuguese Penal Code.
Lease Conflict: Standard Portuguese residential leases prohibit subletting without written landlord consent; operating a short-term rental in a leased unit without that consent constitutes breach of contract and grounds for immediate eviction.
IHRU Overlap: Properties financed through the Instituto da Habitação e da Reabilitação Urbana (IHRU) carry deed-level restrictions that survive ownership transfers;
STR registration on such properties will be rejected by the Câmara Municipal do Porto.
Properties classified under Portugal's Regime Jurídico do Património Cultural (Lei n.º 107/2001, September 8, 2001) require approval from the Direção-Geral do Património Cultural (DGPC) before any change of use, including STR registration.
Interior alterations to meet safety requirements, fire doors, emergency signage, may themselves require heritage authority sign-off, creating a compliance loop that can delay registration by six to twelve months.
Zoning Overlay: Historic core designation (Zona Histórica) imposes additional Câmara Municipal review; approval is discretionary, not automatic.
Consequence of Non-Compliance: Unregistered STR operation in a classified building carries fines under Lei n.º 62/2018 plus separate penalties under heritage law, which can reach €250,000 for severe violations.
Not all short-term accommodation activity in Porto falls under the AL licensing framework governed by Decree-Law 128/2014 and its subsequent amendments.
Stays of 30 consecutive days or more: These qualify as residential tenancies under the Novo Regime do Arrendamento Urbano (Law 6/2006, as amended) and are not subject to AL registration requirements.
Licensed hotels and aparthotels: Properties operating under a hotel classification (empreendimentos turísticos) are regulated separately by Turismo de Portugal under Decree-Law 39/2008, not the AL regime.
Bed and breakfast establishments (Turismo em Espaço Rural): Rural tourism properties and agritourism units operate under a distinct licensing category with separate capacity and safety standards.
Student housing and university accommodation: Purpose-built student residences are exempt, governed instead by Decree-Law 96/2019.
Introduced in 2024, Decreto-Lei 76/2024 amended the prior AL framework established under Decreto-Lei 128/2014 by removing the prior-notice suspension mechanism that had allowed municipalities to freeze new AL registrations in high-density zones. Key changes included:
Suspension Powers Removed: Municipal authorities lost the unilateral right to halt new registrations in saturated areas.
Condominium Veto Retained: Buildings governed by horizontal property law may still prohibit AL activity through a two-thirds owner vote.
Periodic Renewal: Existing AL licenses became subject to review every five years beginning in 2025.
Decreto-Lei 76/2024 was enacted and is in force as of May 2026.
As of May 2026, no additional bills proposing material changes to Porto municipal STR rules are pending before the Assembleia da República or Câmara Municipal do Porto. The most recent enacted change to the national AL framework took effect under Decreto-Lei 76/2024.

Think a neighbor is running an illegal short-term rental in Porto? You've got options. You can report it directly to ASAE* via their online complaints portal at asae.gov.pt or by phone at +351 217 983 600.
Porto City Hall also takes complaints at +351 223 209 700. But let's be clear: ASAE is the main authority here, and they're the ones who handle inspections and slap on the hefty fines, which can run a small business up to €25,000 for non-compliance under Decree-Law 128/2014.
Let's be blunt: this isn't legal advice. It's just a guide. Short-term rental regulations in Porto are a moving target, constantly changing since the 'Mais Habitação' legislative package passed in 2023.
Don't try to navigate this alone. You'll want to consult with a qualified Portuguese lawyer and a tax professional to ensure you're fully compliant with every single rule.
Staying informed is your job, and the requirements aren't getting any simpler.
