New-build warranty in Spain: what it covers and how long it lasts
How many years of warranty does a new build have?
The Building Regulations Act (LOE) sets out the warranty periods for new-build homes – that is, the timeframe within which you can make a claim. The length of the warranty and the applicable deadlines depend on the type of defect affecting the newly built property:
A 10-year warranty covers structural defects affecting pillars, beams, foundations, retaining walls, floors and other structural elements.
A 3-year warranty covers hidden defects or construction and installation faults that affect the habitability of the home or building, such as damp or electrical system failures.
A 1-year warranty applies to defects in finishes, such as loose tiles, loose flooring or similar issues.
These warranty periods begin from the date the construction company delivers the work, not from the date the property is purchased. Owners should therefore take the delivery date into account when calculating the warranty period, as this is crucial when making a claim.
In addition, buyers have up to two years from noticing a defect to request its repair, regardless of the remaining warranty period.
