Teenage daredevil George Henry King-Thompson is named in the injunction secured at the High Court last month.
The document bans anyone from climbing more than two metres above street level on any part of the Wembley Park construction sites.
The injunction is in force until December 2023.
Quintain said: “Quintain Limited and associated companies have obtained a High Court injunction preventing unauthorised access into buildings and building sites at our Wembley Park development.
“This follows a number of incidents where individuals placed themselves and others in danger.
“The injunction was sought against one named individual and other unnamed individuals who may seek to trespass in future.
“We take the safety of the public and our staff extremely seriously.
“Individuals who engage in persistently disruptive and dangerous behaviour put themselves and others at risk of significant harm.
“We will always act to prevent them from doing so.”
