Expert report in homeowners' associations | Balearic Islands

When a communal downpipe bursts, a leaky roof begins to sag, or a faulty electrical installation causes a fire, the affected homeowners face a situation that goes far beyond simply calling a technician. They need to prove who is responsible, what damage has occurred, and how much it will actually cost. In this context, having a rigorous expert technical report makes all the difference between recovering what has been lost and silently enduring the damage.

At Optima Pericial, an expert appraisal firm based in Ibiza and operating throughout the Balearic Islands, we prepare expert reports for private property owners, homeowners' associations, insurance companies, and legal proceedings. Our direct experience in the insurance sector allows us to accurately identify the source of damages and quantify their true extent—two essential elements without which any claim is rendered worthless.

Liability in homeowners' associations: basic legal framework

Before discussing the expert report, it's important to understand the legal framework governing liability within a homeowners' association. The Horizontal Property Law (LPH) clearly establishes the obligations for the maintenance and upkeep of common elements and determines who is responsible when something goes wrong.

Common elements and private elements

In every community, two types of spaces and structures coexist. Private elements include individually owned apartments, commercial premises, and garages. Common elements comprise everything that belongs to the building as a whole: facades, roofs, downpipes, general installations, entrance hall, elevator, and landscaped areas, among others.

This distinction is fundamental because the origin of the damage will determine who has the obligation to repair it and, therefore, who will assume the resulting civil liability.

Article 10 of the Horizontal Property Law (LPH) obliges the community to carry out all the necessary works to maintain the building in safe, habitable, and accessible condition. If the community fails to fulfill this obligation and this results in harm to an owner or a third party, it becomes liable.

Types of civil liability that can be claimed

The liability that can be demanded of a community of owners has two main aspects:

• Contractual liability: when there is a prior legal relationship between the parties, such as a service contract or a work agreement.
• Extracontractual liability: when there is no contract but damage occurs as a result of the action or omission of the community. This is the most common situation in conflicts between neighbors and the community.

In both cases, Article 1911 of the Civil Code establishes that the community will be liable with all its present and future assets. If the community funds are insufficient, the owners may assume subsidiary liability in proportion to their share.

Requirements to be able to claim: the essential triad

For a claim to succeed, case law requires that three elements be proven simultaneously:

1. Existence of a specific and identifiable harm: it is not enough to allege generic damages. The harm must be identifiable, describable, and quantifiable.
2. An action or omission by the community: either by acting negligently or by failing to fulfill its maintenance obligation.
3. Direct causal relationship: the damage suffered must be a direct consequence of that action or omission, without any reasonable doubt about the causal link.

These three elements are precisely what a well-prepared expert report allows to be technically and objectively proven. Without such evidence, the burden of proof falls heavily on the injured party.

Why the expert report is the key element in any claim

A technical expert report is not simply a repair estimate. It is a document with evidentiary value that can be presented to the insurance company, the homeowners' association, or a court, and which rigorously and thoroughly establishes the cause, extent, and cost of the damages.

What should an expert report on damages in a community contain?

A complete technical report prepared for a claim in a homeowners' association must include, at least, the following sections:

• Detailed description of the damage: exact location, nature of the damage (dampness, cracks, detachments, etc.) and extent.
• Causal analysis: technical determination of the origin of the damage and its relationship with common elements or with the negligence of a specific owner.
• Photographic and planimetric documentation: graphic support that backs up the expert's conclusions.
• Economic valuation: quantification of the actual cost of repair, with breakdown of items and updated market references.
• Technical conclusions: professional opinion on the responsibility and actions necessary to resolve the problem.

This set of elements makes the expert opinion a first-rate negotiation and evidence tool, both in extrajudicial proceedings and in court.

The expert witness for the party versus the court-appointed expert

In the field of claims within communities of neighbors, two expert figures coexist with different but complementary roles.

The expert witness is hired directly by the affected property owner (or their insurer) to defend their technical position. Their report serves both to negotiate with the homeowners' association and to be presented as documentary evidence in court.

The court-appointed expert, on the other hand, is designated by the court itself and must act with complete impartiality. Their report carries particular weight in the proceedings, although either party may challenge it with a counter-report prepared by their own expert.

For this reason, having an experienced expert from the beginning of the conflict is strategically advantageous: it allows you to anticipate the opposing party's technical arguments and build a solid defense from the outset.

The probative value of expert opinions in court

Judges value expert evidence as one of the most solid means of proof in litigation of this nature, provided that the report is properly substantiated and consistent with the technical documentation provided.

An expert report that rigorously establishes the causal link between the failure of a common element and the damages suffered by a property owner can directly determine the outcome of the court's decision. Conversely, a technically weak or incomplete report may be dismissed, leaving the claimant without evidence.

At Optima Pericial we know the standards required by the courts of the Balearic Islands and we prepare our reports with the level of detail and rigor necessary to pass that scrutiny.

Most common types of damage in homeowners' associations

The range of issues in homeowners' associations is extensive. Not all damages have the same origin or the same technical solution. Below, we review the most frequent situations that require the intervention of an expert.

Water damage: leaks, dampness and broken downpipes

These are by far the most common types of damage. A faulty communal downpipe, an unmaintained roof, or inadequate waterproofing can cause rising damp, leaks, and seepage that affect several apartments simultaneously.

In these cases, the expert's causal analysis must determine whether the source is a common element (the responsibility of the community) or a poorly maintained private installation (the responsibility of the owner). This distinction is critical and, without a technical report, is often a source of protracted disputes.

The expert report must include, in addition to the location of the leak, an assessment of all secondary damages: deterioration of coatings, damage to electrical installations, damage to furniture or loss of profits if it is a commercial premises.

Structural damage: cracks, fissures and construction pathologies

Structural pathologies in older buildings —especially common in the Balearic Islands' housing stock— can manifest as cracks in load-bearing walls, fissures in floor slabs, or differential settlement in the foundation.

Determining whether a crack is structural or merely superficial requires the technical expertise of a qualified architect or building engineer. The expert must quantify not only the cost of repairs but also the potential risk to the safety of the building and those affected.

In these cases, the expert report becomes even more relevant because it can trigger a civil liability action against the original builder or developer, if the damages are due to construction defects.

Damage to common facilities: electricity, gas and telecommunications

The building's general installations—electrical panels, gas lines, ventilation systems, and shared telecommunications infrastructure—are the responsibility of the building's residents' association. When their poor condition causes an incident (a short circuit, a gas leak, or a malfunction in the extraction system), the affected party needs to prove the link between the community's deficiency and the damage suffered.

The expert must assess the technical condition of the installation, its compliance with current regulations (Low Voltage Electrotechnical Regulation, REBT; Gas Installation Regulation, etc.) and the causal relationship with the incident.

Acoustic damage: noise and vibrations in common areas

Noise pollution problems in apartment buildings are a growing source of conflict. Noisy elevators, poorly insulated air conditioning systems, or activities in communal areas that exceed legal limits can lead to claims for emotional distress and health damages.

In these cases, the expert report must include specific acoustic measurements carried out in accordance with the protocols established by the technical regulations (UNE-EN ISO 16283, for example) and determine whether the levels recorded exceed the thresholds established in the regional and municipal legislation applicable in the Balearic Islands.

Optima Pericial has calibrated acoustic measurement equipment and the necessary technical methodology to prepare reports that can be supported before any administrative or judicial instance.

Damage to facade elements and exterior areas

Detachment of cladding, deterioration of cornices, breakage of ornamental elements or poor condition of the pavement in common areas are situations that, in addition to causing material damage, can cause accidents with serious personal consequences.

In these cases, the community assumes full responsibility if it is proven that it was aware of the poor condition of the element and failed to take the necessary corrective measures. The expert report must demonstrate this prior knowledge—through meeting minutes, communications, or the objective condition of the element itself—and quantify the damages caused.

The claims process step by step: how to act if you suffer damages

Knowing what to do and in what order is just as important as having the right evidence. A mistake in timing or procedure can jeopardize even a technically sound claim.

Step 1: Document the damage from the very beginning

As soon as damage occurs, it is essential to thoroughly document it with dated and time-stamped photographs and videos. Also, keep any written communication with the building manager, the homeowners' association president, or the insurance company.

Do not carry out urgent repairs without first informing the community of the damage and, if possible, without an expert having inspected it. Premature repairs can eliminate evidence that is essential for determining the cause.

Step 2: Formally report the incident to the community

Formal notification to the building manager and the president of the homeowners' association is an essential prerequisite. This must be done in writing with proof of receipt (registered mail, certified mail, or email with read receipts) to document the date the association became aware of the problem.

This notification is especially relevant in cases where the owner has had to carry out urgent repairs at their own expense to prevent further damage. Without this prior notification, the community may not be obligated to reimburse the costs.

Step 3: Commission an independent expert report

Once the incident has been documented and the community notified, the next step is to commission an expert report from an independent technician. This report must objectively and with sound technical expertise determine the cause, extent, and economic value of the damages.

Having an independent expert—not linked to any of the insurance companies involved—guarantees that the report accurately reflects the interests of the injured party and is not conditioned by the coverage limitations of any policy.

If you have any questions about how to start this process in the Balearic Islands, the Optima Pericial team can guide you on the most appropriate steps for your specific situation.

Step 4: Out-of-court negotiation with the community or its insurer

With a solid expert report in hand, the first avenue to explore is always direct negotiation with the community or the insurance company that covers its civil liability. In many cases, the presentation of a well-prepared technical report is enough for the opposing party to acknowledge its responsibility and reach a settlement agreement.

Insurance companies are well aware of the value of a sound expert report. When the report is well-founded, the chances of reaching a satisfactory out-of-court settlement increase significantly, avoiding the costs and length of litigation.

Step 5: resort to legal action if the negotiation fails

If negotiations fail, the expert report will become the primary technical evidence in the civil proceedings. Depending on the amount claimed, the process may proceed as a summary trial (up to €15,000) or an ordinary trial (for higher amounts).

In the oral hearing, the expert may be called upon to ratify and defend their report before the judge. For this reason, it is essential that the professional who prepares the report also has the necessary skills and experience to defend it orally with technical rigor.

Statute of limitations: when you should act to avoid losing your rights

One of the most important factors influencing the success of a claim is compliance with legal deadlines. The Horizontal Property Law does not establish a specific deadline for this type of action, so the general provisions of the Civil Code apply.

The five-year term for owners

The Supreme Court has set a five-year statute of limitations for a property owner to claim compensation from the homeowners' association for damages resulting from the lack of upkeep or maintenance of a common element. This interpretation is based on Article 1964 of the Civil Code.

The calculation of this time limit depends on the nature of the damage. If the damage is permanent (remaining unchanged), the time limit begins when the owner becomes aware of the harm. If the damage is continuous (progressively worsening because the cause is not eliminated), the time limit does not begin to run until the damage ceases.

The one-year term for tenants

If the person suffering the damages is a tenant and not the owner of the apartment or premises, the applicable period is significantly shorter: one year from when the damage was discovered, in accordance with the regime of the tort action of article 1.902

of the Civil Code. This deadline is significantly more restrictive and requires acting quickly in order not to lose the right to claim.

In any case, the interruption of the statute of limitations can be achieved through any reliable act of extrajudicial claim—a registered letter, a formal communication, or the filing of a lawsuit—so it is advisable not to unnecessarily delay the actions once the damage has been detected.

How the community's insurance company operates and why you need your own expert

The vast majority of homeowners' associations have a liability insurance policy that covers damages caused to third parties by defects in common elements. However, the existence of insurance does not guarantee that the compensation offered will be sufficient.

The insurance company's expert does not defend your interests

When a community reports a claim, the insurance company will send its own adjuster to assess the damage. This professional works for the insurer and, although they must act with technical honesty, their assessment is usually limited by the policy's coverage and the company's internal criteria.

It is common for insurance companies' expert reports to undervalue damages, exclude items that are actually compensable, apply excessive depreciation coefficients, or fail to consider all the damages suffered by the affected party.

Having an independent expert prepare their own report allows you to compare both valuations and negotiate from a solid technical position. The difference between the two amounts can be very significant in practice.

The counter-expert report: an effective tool to increase compensation

When the insurer has already issued its valuation and the affected party considers it insufficient, the most effective solution is to commission a counter-expert report: a technical report prepared by an independent expert who analyzes and refutes, with technical and documented arguments, the company's valuation.

A well-structured counter-expert report can point out omissions in the original valuation, demonstrate that incorrect depreciation criteria have been applied, or prove the existence of damages that the insurer has not taken into account.

At Optima Pericial, we have extensive experience reviewing expert valuations for insurance companies. Our direct knowledge of the sector's internal protocols allows us to precisely identify where deviations have occurred and articulate them technically in the counter-report.

What happens when there is a conflict between the experts of both parties?

If the insured's expert report and the insurer's expert report yield differing valuations, most policies include a procedure for a joint expert review, in which both experts attempt to reach an agreement. If they are unable to do so, a third expert is appointed to decide the matter, and their decision is usually binding.

In this context, the technical quality of the report prepared by the injured party's expert is crucial. A well-reasoned expert opinion is more likely to be respected in the expert conciliation process and to influence the final decision.

Special situations: when the community is both victim and perpetrator

There are situations in which a homeowners' association may find itself on both sides of a claim simultaneously. For example, when a fault in a private installation causes damage to common elements, or when the work of an individual owner causes damage to shared areas of the building.

Damage caused by an owner to common elements

When a homeowner carries out works on their property without the required municipal permit or the authorization of the community, and these works cause damage to structural elements or common facilities, the community can claim compensation from them.

In this case, the expert report must establish the causal relationship between the owner's actions and the damage caused to the common elements, as well as quantify the cost of restoring them to their previous state.

Conflicts between neighboring property owners mediated by the community

Sometimes, the damage occurs between neighbors—a pipe in one apartment leaking into the one below, for example—and the building's residents' association acts as an intermediary or is also affected. In these cases, determining the source of the leak is more complex because it may involve both common and private elements.

An experienced building pathology expert can accurately determine whether the problem originates in the upstairs neighbor's private installation or in the communal downpipe, allowing the claim to be directed against the truly responsible party and avoiding unnecessary litigation with uninvolved third parties.

Conclusion: the expert report as a guarantee of your rights against the community

Claiming damages in a homeowners' association without the support of an expert technical report is risky. The law requires proof of the damage, the association's liability, and the causal link between the two, and without a professional opinion, this burden of proof is very difficult to meet.

Having an independent expert from the beginning of the conflict allows you to properly document the damages, negotiate with solid technical arguments against the insurance company and, if necessary, defend your position in court with the maximum guarantees.

In the Balearic Islands, where the housing stock combines historic buildings with more recent constructions and a particular insurance situation, the local experience of the expert is an added factor that can make the difference in the outcome of your claim.
