Moretz's brother, Brandon, went to police after the incidents to obtain a temporary restraining order against 18-year-old Justin Alexander Behr, TMZ reports.
Behr is reportedly facing felony stalking charges following the second trespassing charge.
In court documents obtained by the site, Brandon alleges that Behr scaled their private gate and banged on the windows and doors of the family's home last Sunday.
The actress' family called the police, who arrested Behr — only for the troubled trespasser to return less than a day later.
For his second arrest, Behr's bail reportedly shot up from $1,000 the first time to $150,000.
A rep for Moretz did not immediately return a request for comment.
