Buying an apartment means buying two things at once: the unit itself and a share of everything that's common — the lobby, the pool, the facade, the elevators. The regime that organizes that shared life is called condomínio edilício (condominium regime), and understanding its rules avoids two headaches: an unexpected fine and an impossible neighbor.
Why this is the question every apartment buyer asks sooner or later
Compare the two scenes below — the same noisy neighbor at 2am, two different agents:
- Agent who doesn't know: client asks "what if the neighbor is noisy and there's no way to fix it?" Answer: "then you call the police." The client doesn't know there's a path inside the condominium itself, with a fine that can reach 10 times the condo fee.
- Agent who knows: same question. Answer: "there's the antisocial-behavior fine under article 1,337 of the Civil Code — up to 10 times the condo fee, approved at an assembly by 3/4 of the remaining unit owners. And before buying, you can request the condominium bylaws and meeting minutes to check if that kind of problem has happened in the building before." The client understands the condominium has its own tools, and that it can be researched before signing.
What condomínio edilício is
Governed by Brazil's Civil Code (articles 1,331 to 1,358), the condominium regime is where each individual unit (the apartment) is the owner's exclusive property, and the common areas (lobby, elevators, pool, facade, structure) belong to all unit owners together, each with their own ideal fraction — the percentage proportional to the unit's size within the whole building.
Bylaws vs. house rules: the distinction that confuses everyone
- Condominium bylaws (convenção): the building's "corporate charter" — sets each unit's ideal fraction, rights, duties, and management structure. To be valid and binding on all owners, it must be signed by holders of at least 2/3 of the ideal fractions.
- House rules (regimento interno): the day-to-day rules — move-in hours, party room use, gym rules. Usually easier to amend than the bylaws.
The assemblies: ordinary vs. extraordinary
The Ordinary General Assembly (AGO) happens once a year, to approve accounts, the budget, and, when applicable, elect the building manager (síndico). The Extraordinary General Assembly (AGE) is called whenever an urgent or specific matter comes up outside the calendar — a renovation, a fine, a rule change.
Who can vote (and who's left out)
Voting power is proportional to each unit's ideal fraction, unless the bylaws set it up differently. But there's an important catch: the Civil Code conditions the right to vote on being current on condo fees — a delinquent owner can still attend the assembly, but loses voting rights while in debt.
The 3 fines every unit owner should know
| Situation | Fine | Quorum required |
|---|---|---|
| Late condo fee payment | Up to 2% of the debt + late interest | Automatic, no assembly needed |
| Breaching duties (irregular renovation, altering the facade, harmful use) | Up to 5x the monthly fee | 2/3 to 3/4 of remaining owners, depending on the case |
| Repeated antisocial behavior (incompatible with communal living) | Up to 10x the monthly fee | 3/4 of remaining owners |
Example — the real size of the antisocial-behavior fine
A condominium with a monthly fee of R$2,000, applying the maximum fine for repeated antisocial behavior:
| Item | Value |
|---|---|
| Monthly condo fee | R$ 2,000 |
| Antisocial-behavior fine (10x) | R$ 20,000 |
That's a high enough amount to work as a real deterrent — but it requires the formal assembly process, with the qualified 3/4 quorum of remaining owners.
Keep an eye on: reform in progress
There's a bill (PL 4/2025) moving through Brazil's Congress proposing significant changes to condominium rules — professionalizing management, new rules for collecting from delinquent owners, and clearer mechanisms for dealing with antisocial residents. Until final approval, the current Civil Code rule described here still applies — but it's a topic worth following over the coming months.
In practice: what to check before buying
- Can I see the condominium bylaws? It's a public document among owners — asking isn't rude.
- Is there a history of conflicts or antisocial fines in the building? Assembly minutes usually record this.
- Are the condo fees current? In some cases, the seller's debt can follow the property — confirm before signing.
The difference this makes in a broker's career
Explaining how the assembly, voting, and fines work — before a client has to find out the hard way — is the kind of information that prevents post-sale disappointment and shows the agent understands the whole building, not just the apartment.
