Yes, buyers of new-build homes in Spain have real statutory protection against desperfectos obra nueva under the Ley de Ordenación de la Edificación (LOE), with warranty bands of 1, 3, and a long period depending on the defect. The moment you spot a problem, document it with photos and video, and send a Burofax to interrupt the prescription clock. Commission a peritaje (technical expert report) before anyone touches a wrench.
TL;DR:
- Construction defects in Spain are categorized into finish, habitability, and structural issues, each with different warranty periods from the formal handover date.
- The warranty window begins when a defect manifests, but homeowners must document and report the defect quickly, as prescription periods post-manifestation can shorten the time to file a claim.
- Liability primarily rests with the promoter, who carries decenal insurance, and extends to constructors and designers, with joint liability making claims easier to pursue.
- Accurate evidence collection, including photos, videos, and expert reports, is crucial to protect claims, as repairing defects without documentation can invalidate evidence.
- Homebuyers should send formal notices via Burofax, monitor defects regularly, and involve qualified experts early to maximize their chances of successful resolution.

What Counts as a Desperfecto in a New-Build Property?
Spanish law splits construction defects into three legal categories, and which one applies determines your warranty window and your entire strategy. This is not the same as how a homeowner instinctively sorts problems. A crack might feel minor to you and still be structural in the eyes of the LOE.
The law’s three buckets:
- Finish or termination defects (acabado): peeling paint, loose tiles, misaligned doors, faulty grout, minor plumbing drips. These carry the shortest warranty, just one year.
- Habitability defects: water infiltration, poor insulation causing condensation, faulty waterproofing, ventilation failures that make a home uncomfortable or unhealthy to live in. Covered for several years.
- Structural defects: foundation problems, load bearing wall cracks, roof structure failures, anything threatening the building’s mechanical resistance or stability. These get the full 10-year decenal warranty.
Borderline cases are common and often the most contentious. A damp patch on a bedroom wall could be a cosmetic finish issue or evidence of a structural waterproofing failure at the foundation level. When the cause isn’t obvious, that ambiguity itself is the signal you need an independent peritaje rather than guessing which category applies. Misclassifying a defect can cost you years of warranty coverage you didn’t know you were forfeiting.
How Long Do You Have to Claim Construction Defects in Spain?
The LOE sets three warranty periods running from the date of formal handover, and a separate prescription window that starts only once a defect actually appears. Confusing these two clocks is the single most damaging mistake homeowners make.
The three statutory bands under article 17 of the LOE: one year covers finish and termination defects, several years covers habitability defects, and a long period covers structural defects that threaten the building’s stability.
Here’s the part most buyers miss: the warranty period is the window during which a defect must manifest itself to be covered at all. Prescription is a different, shorter clock. Once a defect shows up, whether that’s month 2 or year 8 of the relevant warranty band, you have a prescription period from that manifestation date to actually bring a claim. Miss that an action window and you can lose your right to sue even though the underlying warranty period hasn’t technically expired.
Both clocks start from the Acta de recepción de obra, the formal reception act signed when the promoter hands the building over to the community or individual owners. This is not the same date as your notarized purchase deed, and treating the two as interchangeable is a common and costly mistake. Ask the promoter or the property administrator for a signed copy of the Acta as soon as you take possession. If nobody can produce one, request it in writing and keep that request on file. Courts have also clarified that for continuous or latent damages, such as slow water infiltration that worsens over months, the manifestation date isn’t always the first tiny sign of trouble; it’s when the defect became reasonably identifiable as connected to a specific cause. That distinction gets argued in court more often than you’d expect.
Who Is Liable for Construction Defects, and How Does Decenal Insurance Work?
The promotor (developer) is your natural first target, and Spanish law makes that choice easier than in many countries because of responsabilidad solidaria, joint and several liability among everyone involved in construction. In practice, that means you don’t have to prove exactly which agent caused the defect before filing a claim.
Under the LOE, liability typically spreads across three roles:
- The promotor, who commissioned the build and sold the units. Nearly all claims name the promotor first because they’re the most visible, most solvent, and easiest to identify from your purchase contract.
- The constructor, the building company that executed the work, liable for execution errors distinct from design flaws.
- The project architect and director of works, liable for design defects or failures in site supervision.
Because liability is often solidary, you can pursue the promotor for the full amount even if the actual fault sits with a subcontractor, then let the promotor fight that out separately with its own insurers and contractors. This is exactly why the promotor is the practical first addressee for nearly every claim.
Structural defects add another layer: article 19 of the LOE obligates promotors to carry seguro decenal, a structural damage insurance, before a new build can even be registered at the notary. If the promotor has vanished, gone insolvent, or simply stopped answering your Burofax, the decenal insurer becomes your direct point of contact. You’ll typically need your peritaje report, the Acta de recepción, and proof of the defect’s structural nature to open a claim file with the insurer.
Pro Tip: Ask for the decenal policy number and insurer name at the time of purchase, not after a crack appears. It’s usually listed in your escritura or can be requested from the notary, and having it ready shaves weeks off a claim.
How Should You Document Desperfectos to Protect Your Claim?
Evidence quality decides whether a claim settles quietly or drags through court for a limited period. Spanish courts and insurers weigh dated, methodical documentation far more heavily than a homeowner’s verbal account, no matter how obviously wrong the tile grout looks in person.
Inspect on a rhythm, not just when something catches your eye:
- At handover. Walk every room with the Acta de recepción in hand and note discrepancies against the sale specifications before signing anything.
- Weeks 1 through 12. Early settling, seasonal humidity, and first heavy rain often reveal finish and habitability issues that weren’t visible on day one.
- Annually during each warranty window. Structural issues especially can take years to surface, so a yearly walkthrough during the 10-year decenal period costs you an afternoon and can save your claim.
At each stage, build a file with dated photographs from multiple angles, a video walkthrough narrating what you’re seeing and when, a written defect list with locations and dimensions, and copies of any community of owners meeting minutes that reference the same issue. If neighbors have noticed similar problems, written statements from them strengthen a shared claim considerably.
For anything beyond obvious cosmetic flaws, commission a peritaje from a licensed architect or ingeniero técnico with LOE litigation experience. A report worth paying for identifies the cause, links it to a specific LOE category, estimates the repair cost, and states a defensible date when the defect became identifiable, which matters enormously for prescription arguments later.
Pro Tip: Never let the promoter’s own technician be your only inspector. A second, independent opinion from an architect you hired yourself carries far more weight in negotiation and in court.
What Are the Steps to File a Construction Defect Claim?
The typical path runs from a formal written notice through negotiation, insurer involvement, and only then to court, and skipping steps rarely speeds things up.
- Send a Burofax with acknowledgment of receipt. This formal notice describes the defect, references the relevant LOE warranty period, and demands repair within a stated timeframe. Its real power is legal: it interrupts the prescription clock the moment it’s delivered, buying you time even if negotiations stall.
- Give the promotor or constructor a defined window to respond. Thirty days is a common ask. Document every proposed repair date, every no show, and every partial fix, since a pattern of delay strengthens a later judicial claim.
- Contact the decenal insurer if the defect is structural or the promotor is unresponsive. Expect to submit the peritaje, the Acta de recepción, your Burofax, and photographic evidence.
- Instruct a lawyer if extrajudicial efforts stall. Judicial claims in Spain generally follow a standard procedural flow of demand, response, evidence hearing, and ruling, and costs scale with the complexity and value of the claim.
Pro Tip: Never accept an informal repair without a written agreement stating the defect, the fix, and the date. An undocumented repair can later be read as you accepting the work as satisfactory, even if the same problem returns.
What Mistakes Cost Homebuyers Their Claims?
The single most damaging habit is patching a defect yourself before anyone documents it. Once you paint over the crack or reseal the leak, you’ve likely destroyed the physical evidence a peritaje needs.
- Never repair before photographing, filming, and getting a written expert opinion, even if the fix seems trivial.
- Keep original receipts, the Acta de recepción, and every Burofax and reply in a single folder, digital and physical.
- A peritaje is often decisive, not optional, once a defect touches structure or habitability rather than pure cosmetics.
- For common areas like roofs, facades, or shared foundations, the community of owners must formally agree to commission a peritaje and split its cost before pursuing the promotor or insurer collectively.
A Local View on Handling Desperfectos in Costa Dorada
Buyers in Cambrils and along the Costa Dorada tend to run into the same handful of issues: waterproofing failures on terraces exposed to sea air, and settling cracks in developments built on reclaimed coastal land. What separates a smooth resolution from a two-year headache is almost always how early the owner documented the problem and how fast the Burofax went out. Local experts in the Costa Dorada region, including architects and legal advisors, understand these regional patterns and can point buyers toward the right first step.

FAQ
What Is the Deadline to Claim Construction Defects in a New Build?
You have three warranty windows depending on the defect type (1, 3, or a long period from the Acta de recepción), plus a separate two-year prescription period to file a claim starting from when the defect actually appears.
What Warranty Does a New-Build Property Come With in Spain?
Under the LOE, new builds carry a 1-year warranty for finish defects, several years for habitability defects, and a long period for structural defects, all counted from the Acta de recepción de obra.
How Long Do I Have to Claim for Poorly Executed Construction Work?
Once a defect manifests within its applicable warranty period, you have a limited period to bring a formal claim, and sending a Burofax with acknowledgment of receipt interrupts that clock while you negotiate or gather evidence.
What Is the Deadline to Claim Damage Caused by Neighboring Construction Work?
Damage from adjacent construction typically falls under general civil liability rules rather than the LOE’s builder specific warranties, and prescription periods can differ, so it’s worth having a peritaje establish causation early and consulting a property lawyer about the applicable civil deadline for your specific case.
