| Source | What it gives us | What it can’t tell you |
|---|---|---|
| Catastro (Dirección General del Catastro) | Address, main use, built area, plot area, year built, the list of built units and the parcel outline | Who owns it, debts or charges, whether building work had a licence. The Catastro is a tax register, not proof of ownership. |
| IGN PNOA aerial photography | A recent aerial photo of the plot, to compare with the parcel outline and the listing | The date of any building you can see, or its legal status |
| MITECO SNCZI flood maps | The mapped 100-year flood zone around the property | Flooding from drains or rain outside the mapped rivers and coasts, or insurance terms |
What we don’t use
The Land Registry. Owners, mortgages, seizures and charges appear only in the Land Registry, and article 332 of the Reglamento Hipotecario forbids putting registry information into a database for resale. We don’t store or resell it. You or your lawyer can order the nota simple directly from the Registradores.
Coastal demarcation (deslinde). The government’s public coastal map service was unreliable when we built this site, so we don’t use it yet. Your lawyer can check the coastal line with the Demarcación de Costas.
Regional exceptions
The Basque Country and Navarre keep their own cadastres (the catastros forales), separate from the national Catastro. For properties there, we point you to the regional service.
Licence and attribution
Catastro data is used under the Catastro’s reuse licence, which allows transformed reuse with attribution. Nothing on this site is an official Catastro certificate. Data from IGN and MITECO is reused under Spain’s public-sector information rules (Ley 37/2007), with attribution.
