Beyond the LOE time limits: architects' contractual liability and owners' associations' standing after Supreme Court Judgment 860/2026
Judgment 860/2026 of 4 June of the “Tribunal Supremo” —Spain's Supreme Court— deals with a case in which an owners' association brought together ten-year liability actions under the “Ley de Ordenación de la Edificación” —the LOE, Spain's building legislation— and contractual actions under article 1101 of the “Código Civil”, the Spanish Civil Code, against an architect and a technical architect. The LOE actions against the two professionals were barred by limitation, but the Supreme Court confirms that this does not necessarily extinguish the contractual route and recognises the association's standing to bring the actions which originally belonged to the developer cooperative. The decision qualifies the obstacle posed by article 1257 CC as regards successive purchasers and owners' associations and makes it possible to clarify the difference between the LOE guarantee periods, the limitation period under article 18 LOE and the limitation period for the contractual action.
1.The case: LOE actions barred by limitation and a contractual claim against the architects
STS 860/2026, a judgment of the “Tribunal Supremo”, Spain's Supreme Court, determines the extraordinary appeals for breach of procedure and the cassation appeals brought by the “arquitecto superior” and the “arquitecto técnico” —the architect and the technical architect— of a building developed under a cooperative scheme against the judgment of the “Audiencia Provincial”, the provincial appeal court, which had held them contractually liable for construction defects. The owners' association, formed after the dwellings had been allocated to the members of the cooperative, sued the architects, the construction company and the insurer, joining ten-year liability actions under the “Ley de Ordenación de la Edificación” —the LOE, Spain's building legislation— with contractual actions under article 1101 of the “Código Civil” —the Spanish Civil Code, CC—.
The court of first instance had held that the LOE action against the architects was barred by limitation and that the owners' association lacked standing to bring the contractual action, applying the principle of privity of contract laid down in article 1257 CC, since the association had not been a party to the “contratos de arrendamiento de servicios” —the contracts for services— entered into between the developer cooperative and the building professionals. It therefore dismissed the claims against the architects and the insurer and made an order only against the construction company, which had not entered an appearance, on the basis of its statutory liability under the LOE.
The Audiencia Provincial of Cádiz partly reversed that decision. It found it proved that the architects had maintained a contractual relationship with the developer cooperative and that, once the dwellings had been allocated and the cooperative dissolved, the contractual actions passed to the members of the cooperative and hence to the owners' association which they formed. On the basis of that standing, it held the architect contractually liable for defective waterproofing in the basements and the technical architect and the construction company jointly and severally liable for other water ingress and damp, ordering them to carry out the repairs or to pay the cost of them.
The architects appealed in cassation, alleging breach of article 1257 CC and of the principle of privity of contract, and arguing that the expiry of the limitation period for the LOE action closed off any claim. The Supreme Court dismisses the appeals and upholds the judgment of the Audiencia Provincial, laying down a ruling of considerable practical importance.
2.LOE guarantee periods, limitation under article 18 LOE and the contractual action: different levels
One of the most important contributions of STS 860/2026 is its clarification that the LOE guarantee periods, the limitation period for the LOE action under article 18 and the limitation period for the contractual action under article 1101 CC operate on different levels. The LOE lays down, in article 17, guarantee periods for physical damage: ten years for structural damage compromising the mechanical strength and the stability of the building, three years for damage affecting habitability and one year for damage relating to finishes. Those periods delimit the time during which the “agentes de la edificación” —the parties involved in the building process— are liable for particular types of physical damage, running from acceptance of the works without reservations or from the remedying of any such reservations.
Article 18 LOE, for its part, sets the limitation period for actions seeking to enforce the liability provided for in article 17 in respect of physical damage arising from defects: two years from the time when such damage occurs. That period relates to the specific ten-year and three-year liability action under the LOE, not to other possible actions. The right of recourse between building agents or by insurers is likewise subject to a two-year limitation period, running from the time when the court decision holding the party liable becomes final or from the time of out-of-court compensation.
The contractual action under article 1101 CC, by contrast, is governed by the general limitation period for personal actions laid down in article 1964 CC, currently five years from the time when performance of the obligation may be demanded. That action allows a party to seek performance of the contract or damages for wilful misconduct, negligence or delay in the performance of contractual obligations. STS 860/2026 points out that the expiry of the limitation period for the LOE action does not necessarily extinguish the contractual action, which may survive if its own limitation period has not yet run.
In the case under consideration the LOE actions against the architects were barred by limitation, but the owners' association had also brought contractual actions, and the Supreme Court confirms that this route is not closed off by the expiry of the LOE limitation period. The architects' contractual liability, arising from their contracts for services with the developer cooperative, may be enforced by those who have succeeded the cooperative as owners of the dwellings and holders of the actions, provided that the personal action is not itself barred by limitation.
3.The contractual link with the building professional and the transfer of actions to successive purchasers
STS 860/2026 also addresses the question of when a contractual link with the building professional truly exists and of how contractual actions pass to successive purchasers and to owners' associations. The architects argued that the association lacked standing to bring contractual actions, since it had not been a party to the contracts for services entered into with the developer cooperative. The Supreme Court rejects that argument and qualifies the obstacle posed by article 1257 CC.
Article 1257 CC provides that contracts take effect only between the parties who enter into them and their heirs, unless the rights and obligations are not transferable by their nature, by agreement or by operation of law, and that, where a contract contains a stipulation in favour of a third party, that party may demand its performance if it has notified its acceptance to the obligor before the stipulation is revoked. The case law has interpreted that provision flexibly in the field of construction and property development, recognising that successive purchasers of a dwelling have standing to bring the actions in respect of construction defects, including those of a contractual nature, which belonged to the original developer.
STS 860/2026 reiterates that case law. It holds that, once the dwellings have been allocated, the members of the cooperative succeed the developer cooperative as holders of the contractual actions against the building professionals, and that the owners' association which they form acquires the power to bring the corresponding actions in defence of their rights, in respect both of common parts and of privately owned units. The actions pass on acquisition of the property, since the new owners are the parties harmed by the defects and the holders of the right to claim.
The Supreme Court stresses that the transfer of the actions is a question of law and not of fact, and that it is not a matter of a presumption but of the application of settled case law on succession to the developer's position. The owners' association, as the body which brings the purchasers together, may bring the contractual actions originally vested in the cooperative, and article 1257 CC does not prevent this. Qualifying the principle of privity of contract is justified by the need to protect purchasers against construction defects and by the very structure of developments carried out under a cooperative scheme.
4.The owners' association's standing and the scope of the claim
STS 860/2026 confirms the owners' association's standing to claim for damage both to common parts and to privately owned units, representing the interests of all the individual owners. The association may act as a collective body in defence of the integrity of the building and of the habitability of the dwellings, joining LOE actions with contractual actions. The order against the architects relates to defective waterproofing in the basements and to water ingress and damp in other areas, affecting both common parts and privately owned parts.
The association's standing is built around the idea that construction defects affect the building as a whole and that their repair must be dealt with as a single matter. The association may claim the repairs or the cost of the repairs, and the architects' liability extends to the damage flowing from their errors in the design and in the supervision of the works, whether these fall under the LOE or are framed contractually. STS 860/2026 strengthens the position of owners' associations in construction disputes, preventing the absence of a direct contractual link with the building professionals from becoming an insurmountable obstacle.
5.The contractual liability of architects and technical architects beyond the LOE
The judgment highlights that the liability of architects and technical architects, the Spanish “aparejadores”, is not exhausted by the LOE. The “Ley de Ordenación de la Edificación” lays down a specific regime of liability for physical damage to the building, with its own guarantee and limitation periods, but it does not exclude contractual liability arising from the contracts for services entered into with the developer. Article 17.1 LOE expressly states that the liabilities under the LOE are without prejudice to contractual liabilities, and article 1101 CC allows damages to be claimed for wilful misconduct, negligence or delay in the performance of contractual obligations.
STS 860/2026 shows that, where the LOE action is barred by limitation, the contractual action may remain open if its own limitation period has not run. Contractual liability may cover damage which, by its nature or by the time at which it manifests itself, does not fit within the LOE guarantee periods, or which has fallen outside them because the specific action has become barred by limitation. Combining the two routes calls for careful analysis of the facts, of the time limits and of the nature of the damage.
The judgment also recalls that contractual liability may be joint and several as between the architect, the technical architect and the construction company, where the cause of the damage cannot be attributed to any one of them or where concurrent fault is proved without it being possible to determine the extent of each party's involvement. The LOE provides for joint and several liability in such cases, and contractual liability may follow the same logic, allowing the injured party to claim against any of those involved and leaving the internal apportionment of liability to the recourse stage.
6.Conclusion: beyond the LOE time limits, the contractual route remains open
STS 860/2026 gives a clear answer to the question whether, once the LOE action is barred by limitation, contractual liability remains open against architects and technical architects. The Supreme Court holds that it does: the expiry of the LOE limitation period does not necessarily extinguish the contractual route, and personal actions under article 1101 CC may survive with their own limitation period. The judgment also recognises the standing of owners' associations to bring the contractual actions originally vested in the developer cooperative, qualifying the obstacle posed by article 1257 CC as regards successive purchasers.
The difference between the LOE guarantee periods, the limitation period under article 18 LOE and the limitation period for the contractual action is becoming a key element of litigation on liability in the building sector. The existence or otherwise of a contractual link with the building professional, the transfer of the actions to purchasers and the standing of owners' associations become central questions. For litigation practice the judgment is a valuable guide: where the LOE periods have run, the contractual route should not be ruled out without more, and owners' associations may be legitimate claimants in proceedings against architects and technical architects in respect of construction defects.
