Objects Falling From a Window or Balcony: Who Is Liable for the Damage

A flowerpot plunging from a balcony, a lit cigarette flicked out a window, a bottle hurled from above: when objects fall or are thrown from buildings onto people walking below, Brazilian law imposes a strict liability regime that can reach both the specific resident and the condominium itself, even without proof of fault.

The Legal Basis for Liability for Fallen or Thrown Objects

The Brazilian Civil Code addresses this situation expressly in Article 938, which provides that whoever lives in a building, or in part of it, is liable for damage caused by things that fall or are thrown from it into an improper place. In modern language, the rule restates an institution that dates back to Roman law, known by the Latin expression actio de effusis et deiectis, which was designed to protect passersby from dangers coming from above.

The key feature of the rule is that it imposes strict liability. This means the victim does not have to show negligence, recklessness, or lack of skill on the part of whoever occupies the property. The victim only has to prove the damage, the causal link between that damage and the fall or throwing, and that the object came from that building. Whether the person acted intentionally or carelessly is irrelevant to the duty to pay compensation.

Liability falls on whoever lives in the unit, not necessarily on the owner. A tenant, a borrower under a free-use loan (comodatário), or anyone who actually occupies the unit may be called on to cover the loss. The law looks at the concrete relationship of use and enjoyment of the space, because that is where the risk of projecting things onto a public street comes from.

The Difference Between Fallen Objects and Thrown Objects

Although the article covers both situations in the same provision, there is an important practical difference. A fallen object implies an involuntary event: a flowerpot poorly balanced on a ledge, a piece of clothing that slips off the clothesline, an air conditioner that comes loose from its mounting. A thrown object, by contrast, implies a voluntary human act, such as tossing trash, liquids, or other items out a window.

In both cases, the resident’s liability remains strict. The difference matters most when the voluntary act is also a separate wrongful act in its own right. Intentionally throwing something that hits another person can amount to bodily injury or, in extreme situations, more serious crimes, so the person responsible may face criminal liability in addition to civil compensation.

There are also falls caused by construction defects or by a failure to maintain facades. Canopies, cladding, and exterior structures that come loose can give rise to liability not only for the resident, but also for whoever had the duty to maintain the building, especially when the area is common property.

When the Condominium Is Liable for the Damage

The great challenge in these cases is proof. In most cases, a victim struck on the sidewalk has no way of knowing which window or balcony the object came from. With a facade holding dozens of units, pinpointing the exact apartment is nearly impossible, and that impossibility cannot be allowed to work against the injured person.

To break the deadlock, Brazil’s higher courts have established the position that when it is not possible to determine the unit from which the object fell or was thrown, the condominium is liable for the damage. This solution shifts the burden of compensation to the community of residents, precisely because the risk is spread across the whole building and the victim cannot be left without protection.

When the responsible window cannot be identified, it is the residents as a group who take on the duty to pay, so that the victim is never left without protection.

This reasoning is usually set aside when the fall comes from an area clearly tied to a single unit, such as an exclusive balcony facing the spot where the accident happened. In that case, liability goes back to the identifiable resident. The condominium rule therefore works as a fallback mechanism when it is concretely impossible to identify the source.

Once the condominium has been ordered to pay, it can seek reimbursement from the person who actually caused the harm, if that person is identified later. This right of recourse (direito de regresso) preserves the principle that whoever caused the damage should ultimately bear its cost, without delaying the victim’s immediate compensation.

Steps for the Injured Victim

After a fall or a thrown object, the first concern is your physical well-being and getting your medical care on record. The medical report, patient chart, and test results document the extent of the injury and serve as the basis for quantifying both material and moral damages. Without that proof, your estimate of the loss is weakened.

At the same time, you should preserve the object that caused the damage and photograph the location, the facade, and the point of impact. Images showing the building’s position, any marks on the sidewalk, and the relationship between the fall and the building’s openings help reconstruct what happened and support the causal link.

A police report (boletim de ocorrência) formalizes your account and fixes a definite date for the incident. Statements from witnesses who saw the accident strengthen the evidence, especially if someone saw the height or direction the object came from. Security cameras on the street, at neighboring businesses, or at the condominium itself can be decisive and should be requested urgently, before the recordings are overwritten.

Once the evidence has been gathered, the victim can seek compensation in civil court. The claim can cover medical expenses, lost profits for the period away from work, any resulting disability, and moral damages for the suffering and the risk to life. Whether to sue the identified resident or the condominium depends precisely on whether the source of the fall can be pinpointed.

Prevention and the Role of Condominium Management

For condominiums, this issue creates a permanent duty of prevention. Internal rules that forbid placing objects on ledges, guidelines on mounting equipment on facades, and periodic maintenance of cladding reduce the risk of falls and, with it, the financial exposure of the residents as a group.

Installing protective screens, nets, and barriers on balconies not only protects children and pets but also lowers the chance of objects dropping onto the street. Awareness campaigns and contractual penalties for risky conduct complete a governance system that protects both third parties and the condominium’s own budget.

Insurance also deserves attention. Policies that cover the condominium’s civil liability can absorb the cost of any judgments, avoiding extraordinary assessments that burden every unit owner. Reading the coverage and exclusions carefully is essential so that the protection matches the building’s real risk.

Frequently Asked Questions

Do I have to prove that the resident was at fault to receive compensation?

No. Liability for things that fall or are thrown from buildings is strict. The victim must show the damage, the causal link, and that the object came from that building. There is no need to prove negligence, recklessness, or intent on the part of whoever occupies the unit. The responsible person’s state of mind does not affect the duty to pay compensation.

What if it is impossible to know which apartment the object fell from?

In that case, the established position in the courts is that the condominium is liable for the damage, precisely because the risk is spread across the entire building and the victim cannot be left without compensation. If the responsible unit is identified later, the condominium can exercise its right of recourse against the person who actually caused the harm to recover what it paid.

What amounts can be claimed in a compensation lawsuit?

Compensation can cover medical and treatment expenses, lost profits for the period away from work, costs related to any permanent disability, and moral damages for the suffering and risk endured. The amount depends on the documentary evidence gathered, which is why a detailed record of your injuries and expenses is decisive to the success of your claim.
