Buying an apartment in Portugal means joining a condomínio. Whether you are taking a sea-view flat in Albufeira, a Vilamoura apartment beside the marina, or a townhouse in a gated golf community, the condomínio is the collective body that will run the building for as long as you own there, and its two organs decide how every common-area euro is spent.

For foreign owners, the rules are often the part of the purchase that is least understood, and the part that creates the most surprise after the deed.

This 2026 guide walks through what a condomínio actually is in Portuguese law, how the propriedade horizontal regime sits behind it, what your permilage means in practice, how the assembly and the administrator function, what changed under Lei 8/2022, which documents you must obtain before signing, and the mistakes that international owners most often make.

What is a condomínio?

A condomínio is the collective body of all owners of fractions in a building governed by the propriedade horizontal regime. It is not the building itself, nor the regime, nor the monthly fee, although the word is used colloquially for all three. Legally, the condomínio has two organs: the assembleia de condóminos (deliberative) and the administrador (executive). Every decision about common parts, every euro collected, and every rule imposed on owners runs through these two organs.

The propriedade horizontal regime

Propriedade horizontal is the legal regime that allows a multi-unit building to be divided into autonomous fractions (fracções autónomas), each with its own title, while keeping a set of common parts (partes comuns) shared by all owners. The regime is set out in Articles 1414º to 1438º-A of the Portuguese Civil Code. The common parts typically include the structure, roof, façade, entrance, stairs, lifts, technical rooms, gardens, swimming pools, and parking areas.

Each building must have a constitutive title (título constitutivo) executed by public deed or authenticated private document, and registered at the Conservatória do Registo Predial. The title defines the fractions, the common parts, and the share each fraction has in the building. Without a valid título constitutivo, you cannot register the property in your name. The condomínio only exists from the moment this title is registered.

The permilage and why your share matters

Each fraction is assigned a permilagem, a per-mille share of the total building set in the título constitutivo. The sum of all permilages equals 1,000.

The permilage determines two things that hit both your wallet and your influence inside the condomínio:

• The size of your monthly or annual quota (condomínio fee)
• The weight of your vote in the assembly

A 47-permilage apartment carries a 4.7 percent vote on any decision. An owner with 150 permil has more weight than three owners with 40 each combined. Understanding your permilage before you sign is not optional; it shapes every decision the condomínio takes afterwards.

The quota: what you pay and what you do not

The quota is paid to the condomínio and covers all expenses for the common parts: cleaning, lift maintenance, gardener, building insurance, administrator fees, electricity for hallways, security, water for common areas, and pool maintenance where applicable. It does not cover anything inside your fraction. Repairs to your kitchen, your A/C unit, your interior plumbing, are entirely yours.

Every condomínio must hold a Fundo Comum de Reserva (common reserve fund) under Decree-Law 268/94. The law requires every owner to contribute at least 10 percent of their share in the condomínio's other expenses to the reserve fund. The fund must be held in a dedicated bank account, opened by the administrator, and is used for larger conservation works (façade repaint, roof replacement, lift overhaul). A condomínio with a healthy reserve fund signals good management; an empty one signals trouble.

Quotas vary widely with the asset class. Basic mid-rise buildings in the Algarve typically run €30 to €100 a month. Modern condominiums with pool, gym, and concierge can reach €300 to €800. Resort-branded residences sometimes go higher.

The assembleia de condóminos: the deliberative organ

The assembleia de condóminos is the deliberative organ of the condomínio. It meets at least once a year, typically in the first quarter, to approve the annual accounts, the budget for the year, and elect or confirm the administrator. Extraordinary meetings can be called by the administrator or by owners representing at least 25 percent of the permilage.

For the first convocation (primeira convocatória), the assembly is installed with owners representing at least 25 percent of the permilage present, but can deliberate only if owners representing more than 50 percent of the total permilage are present or represented. If that threshold is not met, a second convocation (segunda convocatória) is held, typically 30 minutes later, and the assembly can deliberate with whatever owners attend.

Majorities depend on what is being voted:

• Simple majority of those present for routine decisions
• Absolute majority (over 50 percent of total permilage) for ordinary deliberations of consequence
• Two-thirds majority of total permilage for non-urgent works in the common parts
• Unanimity for changes that alter the structure of the building or the constitutive title

What Lei 8/2022 changed

Lei n.º 8/2022 of 10 January, in force since 10 April 2022, modernised several rules around the condomínio:

• Assemblies can now be held by remote means, preferentially videoconference, if the administrator decides or a majority of owners require. Foreign owners can vote without flying in.
• Sellers must obtain a written declaration from the administrator stating all current charges on the fraction. This declaration is now a mandatory document for the deed and must be issued within 10 days of request. It makes hidden quota debts much harder.
• Changes to the constitutive title affecting common parts no longer always require unanimity. A court can fill the gap when dissenters represent less than 1/10 of the building's capital, the change does not alter the use, value, or purpose of the fractions, and it concerns common parts.
• The administrator's responsibilities were broadened, particularly in financial management and legal initiative.

The remote-voting rule is the single most useful change for international owners.

The administrador: the executive organ

The administrador is the executive organ of the condomínio, elected by the assembly. It can be a fellow owner or a professional firm. Professional administration is the norm in Algarve buildings with significant foreign ownership, because of language, accountability, and continuity. The administrator enforces the regulamento, manages the budget, operates the condomínio's bank account, calls assemblies, executes their deliberations, and represents the condomínio in legal matters.

The regulamento: rules that bind you

The regulamento de condomínio is approved by the assembly and binds every owner. It covers items such as noise hours, use of common areas, pets, aesthetic rules (balcony plants, awnings, A/C unit placement), and crucially, whether Alojamento Local short-term rental is permitted in the building. Some Algarve condomínios have voted to restrict or prohibit AL. If short-term rental income is part of your investment thesis, read the regulamento before signing, not after.

What foreign owners most often get wrong

The most common mistakes we see in due diligence:

• Skipping the regulamento and discovering an AL prohibition after closing
• Not asking for the last three AGM minutes (atas) to understand recurring issues and votes
• Not checking the fundo comum de reserva balance, which can indicate underfunded major works ahead
• Not verifying outstanding quotas on the fraction, despite the Lei 8/2022 declaration being mandatory
• Assuming the quota covers interior maintenance
• Not appointing a procurador (representative with power of attorney) if non-resident, then missing votes that affect the investment

FAQ

Can a foreign owner attend the AGM remotely?

Yes. Since Lei 8/2022, assemblies can be held by videoconference. You can also appoint a procurador via power of attorney.

What happens if I do not pay the quota?

Outstanding quotas accrue interest and can lead to legal action, with the condomínio able to obtain a court ruling and execute against the fraction. The unpaid amount also follows the property to any sale, blocking the deed until cleared via the administrator's declaration.

Can the condomínio forbid Alojamento Local?

Yes, by deliberation of the assembly with the required majority. Existing AL registrations may have grandfather protections depending on the regulation and timing. Review the regulamento and any AL-related deliberations in the recent atas before buying.

Do I inherit the previous owner's unpaid quotas?

Effectively yes, because outstanding charges burden the fraction. This is why Lei 8/2022 made the administrator's declaration mandatory at the deed.

What documents should I get before signing?

The constitutive title, the latest regulamento, the administrator's declaration of charges on the fraction, the last three years of AGM minutes (atas), the current year's approved budget, and confirmation of the fundo comum de reserva balance.

Where ICON Property fits in

The condomínio is the part of an apartment purchase that creates most foreign-owner regret. A clean fraction in a poorly run condomínio can underperform a less glamorous unit in a well-managed one. Before any buyer of ours signs an offer on an apartment, we pull the constitutive title, the latest regulamento, the administrator's declaration, the last three AGM minutes, and the fundo de reserva balance. We tell you what is normal, what is a yellow flag, and what is a deal-breaker.

ICON Property guides buyers through the full condomínio due diligence and points clients toward licensed administradores when independent management is the right call.
