DGR,
Beware of the so-called 10 year building warranty…
This usually is not an additional warranty but many, many developers will try to tell and convince you so…
If you don’t have an additional warranty signed by the developer/builder in writing or a valid copy of their insurance policy you will only have the general law (‘Ley de Ordenación de la Edificación’ or General Building Act) warranties:
1 year for minor defects (finishing details) only against the builder
3 year for general defects, and
10 years for mayor defects (only those affecting the building structure or stability)
This Law is applied to every building in Spain with a license requested after 05/06/2000
Lots of times you will have to go to court to get your rights granted, belive me, I tell you this as I usually represent the ‘enemy’ in this kind of building defect lawsuits as lawyer of Architects… 😈
Architects have most of times a decent insurance policy and there are many times when they have even to deal with promoters and builders insolvency 😥
