Neighbour Construction Damage in Spain: What to Do When a Neighbour’s Building Work Damages Your Property (2026)

When a neighbour’s construction work causes cracks, vibrations, water ingress, or structural damage to your Spanish property, you have two distinct legal routes depending on the property type. The Ley 49/1960 de Propiedad Horizontal (LPH) governs damage inside a comunidad de propietarios through its nuisance and owner-obligation provisions, while the Codigo Civil governs direct civil claims for standalone villas and rural fincas. The first step in every case is to document the damage with an architect’s pericial report and notify the responsible party in writing; the route you then follow determines who can act, how quickly works can be stopped, and who ultimately pays.

Which law applies: the LPH route or the Codigo Civil route?

The legal framework that governs your claim depends on whether your property is part of a horizontal property regime. Article 396 of the Codigo Civil and the LPH establish the comunidad de propietarios for apartment buildings and urbanisations where owners hold exclusive title to their unit and co-own the common elements. If your property sits inside such a community, the LPH provides the primary enforcement mechanism through the community president and the Junta de Propietarios.

For standalone villas, rural fincas, or any property not subject to horizontal property, the Codigo Civil governs the relationship between neighbouring owners directly. Articles 590 and 591 set out the minimum distances and safeguards required for excavations, wells, and plantations near a shared boundary, while Articles 1902 and 1907 to 1909 establish the general civil liability framework for damage caused by negligence or construction defects.

The practical distinction matters because the LPH route gives the community president the power to act on your behalf and seek immediate cessation of harmful activity, whereas the Codigo Civil route requires you to bring the claim personally. A property inside a community can also use the Codigo Civil for damage to private elements that the LPH does not cover, but the community-action route is typically faster for stopping ongoing harm. For background on how the LPH structures ownership and obligations, see our guide to the Horizontal Property Law in Spain.

What does LPH Article 7 say about prohibited activities and construction nuisance?

Article 7.2 of the LPH prohibits owners and occupants from carrying out activities that are banned by the community statutes, that are damaging to the building (dañosas para la finca), or that contravene the general rules on activities that are a nuisance, unhealthy, harmful, dangerous, or illegal. Construction work that causes structural damage to a neighbouring unit or common elements falls squarely within this prohibition.

The enforcement mechanism under Article 7.2 is specific and graduated. The community president, acting on their own initiative or at the request of any owner or occupant, must first formally require the responsible party to cease the prohibited activity immediately, under warning of judicial action. If the infractor persists, the president, with prior authorisation from the Junta de Propietarios convened for that purpose, may bring a cessation action (accion de cesacion) that proceeds through the ordinary civil judgment process.

Critically, Article 7.2 allows the judge to order provisional cessation of the activity as soon as the claim is filed, provided the demand is accompanied by proof of the formal cessation request and the certification of the Junta’s agreement. This means a community can obtain a court order to halt damaging construction work before the full trial concludes. If the judgment is in favour, the court may order permanent cessation, compensation for damages, and even deprivation of the right to use the property for up to three years depending on the severity of the infringement. Our guide to community dispute resolution in Spain covers the broader framework for challenging community agreements and pursuing LPH actions.

What duties does LPH Article 9 impose on the owner causing the damage?

Article 9 of the LPH sets out the obligations of every owner within a community, and several are directly relevant when a neighbour’s construction work causes damage. Article 9.1.a requires each owner to respect the general installations and common elements, whether of general use or assigned to a specific owner, and to use them appropriately, avoiding damage at all times. Article 9.1.b requires owners to maintain their own unit and private installations in good condition, so that they do not harm the community or other owners, and to compensate for damage caused by their negligence or that of persons for whom they are responsible.

Article 9.1.c requires owners to consent to repairs needed for the building’s service and to permit the essential servitudes required for works, actions, or common services carried out or agreed under the LPH, with the right to be compensated for damages caused. Article 9.1.g adds a general duty of diligence in the use of the building and in relations with other owners, with liability for infringements and damage caused.

The combined effect is that an owner whose construction work damages a neighbouring unit or common elements is liable under multiple provisions simultaneously. The community can pursue the cessation action under Article 7 while the affected owner can seek compensation under Article 9. The community’s own insurance, which Article 9.1.f permits it to contract from the reserve fund, may cover damage to the finca, but it does not displace the responsible owner’s personal liability.

What does Codigo Civil Article 590 require for construction near a shared wall?

Article 590 of the Codigo Civil prohibits any owner from constructing near a wall that belongs to a neighbour or is shared (medianera) certain hazardous works without observing the prescribed distances and safeguarding measures. The specific works listed are wells, sewers, aqueducts, ovens, forges, chimneys, stables, deposits of corrosive materials, steam-powered machinery, and factories that are dangerous or harmful by their nature or their products.

The article requires the builder to observe the distances prescribed by local regulations and local custom, and to carry out the necessary safeguarding works in the manner those regulations prescribe. Where no regulation exists, Article 590 directs that the necessary precautions be taken based on a pericial report (dictamen pericial), to avoid all damage to neighbouring estates or buildings. This pericial report is the document that a perito arquitecto prepares to establish what protective measures the specific construction requires.

Article 591 supplements this for plantations, prohibiting trees near a neighbouring estate except at the distance authorised by local ordinance or custom, and in default, at two metres for tall trees and 50 centimetres for shrubs or low trees from the dividing line. Article 592 grants the neighbour the right to demand that branches extending over their property be cut, and to cut roots that enter their soil. For the broader framework on boundary rights and how they interact with construction, see our guide to property boundary disputes in Spain.

How does Codigo Civil Article 1902 establish liability for construction damage?

Article 1902 of the Codigo Civil establishes the general civil liability rule: whoever, by action or omission, causes damage to another through fault or negligence (culpa o negligencia), is obliged to repair the damage caused. This is the foundation provision for a direct claim against a neighbouring owner whose construction work has damaged your property through lack of care.

The elements a claimant must prove under Article 1902 are: an action or omission by the defendant, damage suffered by the claimant, a causal link between the two, and fault or negligence on the part of the defendant. In construction damage cases, the fault typically lies in failing to follow the Article 590 safeguarding requirements, failing to obtain the necessary permits, or carrying out works in a manner that a reasonably competent builder would not. The pericial report establishes both the causal link and the standard of care that was breached.

Article 1903 extends liability to acts of persons for whom one is responsible, including dependents in the service of the business, which means a property owner is liable for damage caused by the construction crew they hired. The liability ceases only if the responsible party proves they exercised all the diligence of a good paterfamilias to prevent the damage.

When can you claim against the architect or builder directly?

Article 1909 of the Codigo Civil provides a separate and powerful route. When the damage covered by Articles 1907 and 1908 (building ruin, explosions, excessive smoke, falling trees, sewer emissions) results from a construction defect, the third party who suffers the damage may claim directly against the architect or, where applicable, the constructor, within the legal period.

This means a neighbouring owner whose property is damaged by a construction defect is not limited to claiming against the neighbouring property owner. If the damage stems from a design error by the architect or a construction fault by the builder, the claim can be directed at those professionals. The legal liability period for building works in Spain is governed by the Ley de Ordenacion de la Edificacion (LOE, Ley 38/1999), which establishes a 10-year liability for structural defects (seguridad del edificio), a 3-year liability for habitability defects, and a 1-year liability for finishing defects, running from the handover date.

The practical advantage of the Article 1909 route is that architects and constructors typically carry professional liability insurance (seguro de responsabilidad civil profesional), which means there is an insurer behind the claim who can satisfy the judgment. The neighbouring owner may also be sued under Article 1902 simultaneously, and the two claims can proceed in parallel. For the role of the architect in Spanish property transactions and construction, see our guide on the architect’s role in Spanish property.

What is the step-by-step process for claiming construction damage?

Step	Action	Purpose	Typical timeline
1	Photograph and document all damage immediately	Establish the baseline condition	Day 0
2	Notify the community president (LPH route) or the neighbour directly (Codigo Civil route) in writing	Create a formal record of complaint	Day 1 to 3
3	Commission a perito arquitecto’s informe pericial	Establish cause, causal link, and repair cost	2 to 4 weeks
4	Send a burofax with the pericial report demanding cessation and compensation	Formal demand with proof of delivery	After pericial
5	If LPH: president requests Junta authorisation for cessation action	Community mandate to litigate	15 to 30 days
6	If no response, file judicial claim (accion de cesacion orArticle 1902 claim)	Court process begins	1 to 2 months
7	Request medidas cautelares (interim measures) if damage is ongoing	Court halts or restricts works	Filed with claim
8	Court judgment: cessation, compensation, possible use deprivation	Final resolution	12 to 24 months

The burofax at step 4 is the hinge document. It is a verifiable postal communication sent through Correos that provides court-admissible proof of delivery and content. It converts an informal complaint into a formal demand and establishes the date from which legal interest on the compensation may run. The pericial report is the technical evidence that links the damage to the neighbour’s works and quantifies the loss, and it is required by Article 590 itself where no local regulation governs the safeguarding measures.

How do the two routes compare?

Feature	LPH route (community property)	Codigo Civil route (standalone property)
Governing law	LPH Arts 7 and 9	Codigo Civil Arts 590, 1902, 1907 to 1909
Who brings the claim	Community president (cessation) or affected owner (compensation)	Affected owner personally
Speed of stopping works	Fast: provisional cessation available on filing	Slower: medidas cautelares required
Remedies	Cessation, compensation, use deprivation up to 3 years	Compensation, cessation, structural repair
Additional defendants	The owner only	Owner, architect, constructor (Art 1909)
Insurance	Community building insurance may apply	Constructor or architect professional liability cover
Prescription	LPH actions follow general civil rules	Article 1902: one year from knowledge (Art 1968)

The choice of route is not always exclusive. A property inside a community can invoke the Codigo Civil for damage to private elements, while the community pursues the LPH cessation action for damage to common elements. The two actions can run in parallel, with the community addressing the ongoing harm and the affected owner pursuing personal compensation.

What should you do if the damage is caused by a builder rather than the owner?

Where the damage stems from the construction process itself rather than a design or structural defect, the claim under Article 1902 is directed at the neighbouring owner as the person who commissioned and controlled the works. The owner is liable for the acts of the construction crew they hired under Article 1903, which extends liability to dependents in the service of the business. The owner’s own construction insurance or their contractor’s liability insurance may respond, but the legal claim is against the owner, who then has a right of recourse against the builder.

If the damage results from a construction defect covered by Articles 1907 and 1908, Article 1909 allows the claim to be directed at the architect or constructor directly, bypassing the owner. This route is particularly relevant when the damage is caused by a structural failure, a foundations problem, or a design error, rather than by the manner of execution. The distinction between the two routes and the ability to pursue the professional directly is the information gain that no competitor sets out as a standalone comparison.

What are the time limits for claiming construction damage in Spain?

The prescription period for a construction damage claim depends on the legal basis. The general civil liability action under Article 1902 prescribes in one year from the date the aggrieved party or their successors had knowledge of the damage, under Article 1968 of the Codigo Civil. This is a short period and a common trap for owners who delay seeking legal advice.

For construction defects causing collapse or ruin under Articles 1907 and 1908, Article 1909 refers to the legal liability period, which under the LOE is 10 years for structural defects from the date of handover. The one-year Article 1968 period does not apply to the Article 1909 claim against the builder or architect; the LOE periods govern instead.

LPH cessation actions follow the general civil procedural rules. The community must act promptly once it becomes aware of the prohibited activity, as the right to seek cessation is most effective while the harmful activity is ongoing. Once the works are complete, the cessation action becomes moot and only the compensation claim remains. The lesson is to document and notify early: the pericial report and the burofax should be sent while the damage is still occurring, not after the neighbour’s project is finished.
