Structural defect warranties in the EU can run for a full decade — but the exact protection, and who insures it, varies significantly depending on which country you're in.
Where this legal concept comes from
Decennial liability (responsabilité décennale) originates in French law, specifically Articles 1792 through 1792-6 of the French Civil Code, and has been adopted with variations across several civil law jurisdictions in Europe and beyond. The core idea is consistent: certain serious construction defects carry a strict, roughly 10-year liability, regardless of whether the builder or professional is shown to be personally at fault.
Spain's LOE: a tiered 10-3-1 system
Spain's Ley de Ordenación de la Edificación (LOE) creates three separate warranty tiers based on defect severity: 10 years for defects affecting structural stability (foundations, load-bearing walls, structural frames), 3 years for defects affecting habitability (waterproofing failures, deficient electrical systems), and 1 year for finishing/completion defects. Claims for material damage must generally be brought within 2 years of the damage actually appearing, separate from the underlying 10/3/1-year coverage windows. For new builds specifically, mandatory decennial insurance (seguro decenal) must be taken out before the property is registered, and this insurance travels with the building on resale, not just with the original buyer.
France's décennale: strict liability plus pre-funded repairs
France mandates a 10-year décennale insurance policy for every construction professional, covering structural stability and weathertightness defects, with liability presumed rather than requiring the owner to prove fault. Critically, France also requires the property owner (maître d'ouvrage) to separately hold a dommage-ouvrage policy, which pre-funds repairs without waiting for fault to be established through litigation — enabling much faster remediation than a fault-based claim would allow. Unlike some other jurisdictions, France's 10-year decennial period is not extended by any further limitation period once the clock starts.
What generally falls outside decennial-style protection
Both systems draw a similar line: cosmetic issues, minor finishing defects, and ordinary wear from normal use typically fall outside the strict structural/decennial warranty, even within the coverage window. The test in most of these systems is functional — does the defect compromise structural stability or make the building unsuitable for its intended use, or is it a lesser issue better addressed under a shorter warranty tier or ordinary contract remedies.
How to make a claim in either system
- Identify exactly which tier your defect falls into — structural (longest coverage) versus habitability or finishing (shorter windows) — since this determines your available time and remedy.
- Get an independent technical assessment (a chartered surveyor, architect, or technical architect's report) establishing that the defect is genuinely structural or covered, not cosmetic.
- Check whether mandatory insurance (seguro decenal in Spain, décennale/dommage-ouvrage in France) is in place — this is usually a faster route to repair than pursuing the original builder directly, especially if that builder has since gone out of business.
- Act promptly once a defect is discovered — shorter claim-filing windows (like Spain's 2-year rule from when damage materialises) run independently of the underlying warranty period.
What this means practically
- A defect appearing years after a renovation may still be covered — check which warranty tier and country-specific system actually applies before assuming it's too late.
- Structural defects get the longest protection (10 years) in both Spain and France; cosmetic and finishing issues get much shorter windows.
- Mandatory insurance in both systems means a claim doesn't always depend on the original contractor still being in business.
- Get an independent professional assessment early — whether a defect counts as "structural" for warranty purposes is often the crux of the claim.
