EAGLED-EYED Hacienda helicopters have been flying over Spain in search of undeclared constructions.
More than three million homes have already been inspected countrywide, those found with undeclared alterations facing hefty fines.
Thousands of fines have already been issued by the cadastral regulatory body to proprietors found to have built extra rooms, terraces, pools or sheds without proper planning permission.
Those ‘caught’ are issued with an initial fine of €60 and face further punishment and legal fees.
Cadastral came into force in 2013 and will run until 2016 to assess the country’s property situation.
The regulatory body will provide an increase in revenue for municipalities by detecting additions to properties listed on the property Tax register (IBI).
Properties deemed to have ‘increased’ in size face the prospect of moving tax bracket and therefore paying more in IBI costs.
The Real Estate Cadastre Law states that any home modifications must be reported to the Land Registry office within two months of completion.
