The Pre-scan is carried out by an architect specialized in so called urbanismo, the only professional who can correctly assess the situation. A lawyer then reviews the report legally and comes up with conclusions and recommendations.
Based on information obtained from the Land Registry, Registro de la Propiedad and the municipality, an architect can determine whether a property meets the current standards. The Pre-scan leads to very important conclusions and recommendations, on the basis of which you can determine whether you want to continue the purchase process.
The reason for the Pre-scan is to prevent you from spending unnecessary money for further research for an illegal, non-legalizable home or a property that does not meet your conditions.
