Short-Term Rental Regulations in Portugal

Portugal was one of the early movers in Europe in creating a dedicated legal framework for short-term rentals. The Alojamento Local (AL, or local accommodation) regime, established in 2008 and heavily reformed since then, provides a nationwide system for registering and regulating tourist rental properties. Portugal's experience illustrates both the benefits of early regulation and the challenges of adapting to a rapidly evolving market.

Current Regulatory Framework

The Alojamento Local framework was created by Decree-Law 128/2014, building on earlier provisions from 2008. It established a registration system under which property owners must notify the local municipality of their intention to operate a short-term rental and obtain an AL license before listing on any platform. Properties are classified into categories including apartments, houses, and guest rooms (quartos), each with specific requirements.

In 2023, the Portuguese government enacted the "Mais Habitacao" (More Housing) package, which introduced sweeping changes to the AL regime. Key reforms included the suspension of new AL licenses in areas designated as having "housing pressure" (which includes Lisbon, Porto, and many other municipalities), the requirement for existing AL licenses to be periodically revalidated, a mechanism for condominium assemblies to vote against AL operations in their buildings, and the possibility for the government to transfer AL-licensed properties to affordable housing programs in exchange for tax incentives.

The reforms also introduced a new "extraordinary contribution," essentially a surcharge, on AL properties in certain areas, designed to capture some of the economic benefit of tourist accommodation for the public purse and to discourage the conversion of housing to tourist use.

Key Requirements

• All short-term rental properties must be registered under the Alojamento Local regime and hold a valid AL license
• New AL licenses are suspended in municipalities designated as housing-pressure areas
• Existing licenses must be periodically revalidated and can be revoked if requirements are not met
• Condominium assemblies can vote to oppose AL operations in their building, subject to voting threshold requirements
• Properties must meet safety and habitability requirements defined by the AL regulations
• Operators must collect and remit local tourist taxes where applicable
• AL registration numbers must be displayed on all advertising and listed on booking platforms

Enforcement

Portugal's enforcement of the AL regime has been strengthened by the registration system, which provides authorities with a database of licensed operators that can be cross-referenced with platform listings. The national tourism authority (Turismo de Portugal) and local municipalities share enforcement responsibilities.

The 2023 reforms enhanced enforcement by requiring platforms to display AL registration numbers and by increasing penalties for operating without a valid license. However, enforcement capacity varies across the country. Lisbon and Porto, as the largest and most heavily affected cities, have the most active enforcement operations. Smaller municipalities may have fewer resources to dedicate to AL compliance monitoring.

The condominium vote mechanism introduced in 2023 gives building communities a new enforcement tool, though organizing the required votes can be challenging in practice, particularly in buildings with many absentee owners.

What This Means for Long-Term Renters

Portugal's regulatory evolution represents a decisive shift toward protecting the long-term housing market. The suspension of new AL licenses in housing-pressure areas and the revalidation requirement for existing licenses are designed to slow or reverse the conversion of residential properties to tourist accommodation. For long-term renters, these reforms should gradually improve housing availability and reduce upward pressure on rents in affected areas.

However, the effects are playing out over time. In Lisbon and Porto, where AL activity was deeply entrenched before the reforms, the existing stock of licensed properties continues to operate. The impact of the reforms will depend on how many licenses are not renewed during revalidation and how many operators choose to convert their properties to long-term rental use in response to the changing regulatory incentives.

Long-term renters in Portugal should be aware that the regulatory environment is still evolving. The 2023 reforms have been controversial, and future governments may adjust the framework. Regardless, the trend toward greater regulation and protection of the long-term rental market appears well-established. Renters should check whether their target municipality is designated as a housing-pressure area and whether the building's condominium association has taken action regarding AL operations.

How BnBDetector Helps

Portugal's Mais Habitacao reforms froze new AL licenses and forced revalidation of existing ones. BnBDetector shows you whether those changes are actually reducing STR activity in your target municipality and building, or whether the old patterns persist.
