Purchasing a newly built or extensively renovated home is, for many, one of life’s most significant investments. Whether buying directly from a developer or acquiring a previously owned property that has undergone comprehensive renovation works, buyers naturally expect modern construction standards, high-quality materials, and a safe, habitable living space.


However, these expectations can be quickly frustrated when, shortly after moving in, the property begins to reveal serious construction defects, such as water infiltration, structural fissures, or insulation failures.


This insight focuses specifically on such situations, that is, when the home purchased is either newly constructed or subject to extensive renovation works prior to the sale. It does not apply to buyers of older, second-hand homes sold by private individuals without substantial recent works.

In the cases covered, Portuguese law offers important protections to homeowners, provided they act promptly and in accordance with the legal procedures in place.

The Portuguese Civil Code establishes a warranty regime applicable to construction work. Under Article 1225, the constructor and, in certain cases, the seller may be held liable for defects that compromise the safety, stability, or intended use of the building. This legal liability extends for a period of five years from the date of delivery of the completed work. During this period, any construction-related defect - whether concerning structural integrity, waterproofing, or foundational issues - may give rise to a legal claim. However, the law places a corresponding obligation on the buyer: the defect must be reported within one year from the date it is discovered. Timely notice, preferably in writing and sent via registered post with acknowledgment of receipt, is essential to preserve legal rights.


In addition to the Civil Code, Portuguese legislation provides enhanced consumer protection in transactions involving private individuals purchasing property from professional sellers or developers. Decree-Law no. 84/2021, provides for a ten-year warranty in situations where the defect compromises the structural safety of the property. This extended protection ensures that even if a latent defect is discovered several years after the purchase, the buyer may retain their rights, provided the issue affects the building’s structural integrity.


Together, these legal regimes ensure that purchasers of newly constructed homes benefit from a minimum of five years and, in some cases, ten years of legal coverage, depending on the nature of the defect and the contractual relationship.


Construction defects may be apparent, such as visible cracks or water stains, or latent, such as insulation failures or foundational deficiencies. Common examples include water infiltration from roofs or façades, structural fissures in walls, ceilings, or floors, defective or absent waterproofing and thermal insulation, failures in plumbing or drainage systems, and damage resulting from poor soil conditions or execution errors. Any defect that compromises the intended use, safety, or value of the property may give rise to legal claims.


The Portuguese Civil Code, particularly Articles 1207 to 1225, sets out the legal framework applicable to such defects and the purchaser’s right to seek appropriate forms of redress. These include repair of the defect at the expense of the responsible party (whether builder or seller), a reduction in the purchase price to reflect the diminished value of the property, or even termination of the contract where the defect renders the property unfit for its intended purpose. In addition, under Article 798, failure to fulfil contractual obligations may entitle the buyer to claim compensation for breach of contract, including damages arising from alternative accommodation or other related expenses.


Upon discovering a defect, it is essential that the buyer act promptly and in a structured manner. The first step involves documenting the issue in detail, including photographic and video evidence, as well as dated records indicating when the defect was first observed. All receipts or invoices related to mitigation efforts or associated expenses should be retained.


The responsible party should then be notified by means of a registered letter with acknowledgment of receipt, clearly describing the nature of the defect and requesting appropriate remedial action. It is further recommended to obtain an independent technical assessment from a duly qualified engineer or architect. Such expert reports may prove critical in substantiating the existence of the defect and attributing liability, particularly if the matter proceeds to formal dispute resolution. Should the issue remain unresolved, or if the response is unsatisfactory, legal advice should be sought without delay. If an amicable resolution cannot be reached, the matter may be referred to the courts or to alternative dispute resolution mechanisms such as arbitration or mediation. In either case, the quality of documentation and the reliability of expert evidence will be central to the outcome.


It should be underscored that, although the applicable warranty periods may extend to five or ten years depending on the circumstances, the exercise of these rights is subject to strict procedural requirements. In practice, the most common reason for the loss of legal protection is the failure to report the defect within one year of its discovery. This deadline is peremptory: even significant defects occurring within the warranty period may be deemed unenforceable if timely notice is not provided.


The discovery of construction defects in a newly acquired property can be a source of considerable frustration and uncertainty. Nevertheless, the Portuguese legal framework provides purchasers clear and enforceable rights. Through proper documentation, compliance with notification requirements, and guidance from qualified legal counsel, property owners can take the necessary steps to protect the value of their investment and assert their rights under the law.

On 16 July 2025, the Portuguese Parliament approved major changes to the legal framework governing immigration (Law no. 23/2007). The reform ends the manifestação de interesse mechanism, tightens rules for job-seeker visas and family reunification, and sets a final deadline for transitional applications.

The Portuguese Parliament has decided to postpone the vote on the proposed amendments to the Nationality Law until September 2025. The decision was taken in a meeting of the Committee on Constitutional Affairs, Rights, Freedoms and Guarantees, following pressure from several political parties who requested more time to assess the implications of the proposed reform. The delay allows for additional hearings with legal experts, immigrant associations and civil society representatives before a final vote is held in plenary session. The proposed reform introduces significant changes to the current legal framework for acquiring Portuguese nationality. Among the most impactful measures is the extension of the minimum legal residence period required before applying for naturalisation. Under the new proposal, this period would increase from the current five years to seven years for nationals of CPLP countries (Community of Portuguese Language Countries), and to ten years for applicants from all other countries. Another major change concerns the introduction of mechanisms to revoke Portuguese nationality . According to the proposal, naturalised citizens who are convicted of serious crimes — defined as those resulting in prison sentences of five years or more , within ten years of acquiring nationality — could see their Portuguese citizenship revoked by a court decision, based on a proposal from the Public Prosecutor’s Office. In addition, the reform would tighten the requirements for acquiring original Portuguese nationality through birth in Portugal. For children born in Portuguese territory to foreign parents, it would become mandatory that at least one parent has been residing legally in Portugal for a minimum of three years , instead of the current two years. Although the government initially intended to approve these changes before the summer recess, political consensus has not yet been reached. Left-wing parties have raised concerns regarding the constitutionality of retroactive revocation of nationality and the potential impact on the rights of long-term residents and immigrant communities in Portugal. In response, the parliamentary committee agreed to postpone the process and schedule a new round of expert hearings in early September. A final vote on the reform is now expected to take place later that month. Until then, the current version of the Nationality Law remains in force , including the five-year legal residence requirement for naturalisation. Applicants who meet this requirement and wish to apply under the current rules may still do so in the coming weeks.
