If the surface of the buildings or the stadium is different in the EN.F.I.A certificate, what deviation is tolerable to consider this certificate to be valid?

The presentation or attachment of the EN.F.I.A certificate is considered valid when  the building is plotted with a deviation of its surface up to five (5) square meters, and the plot is delimited by up to 2% of their surface or omitted or mistaken information that does not affect the tax identity of the property and does not imply a reduced tax.
