The Interfraternity Council at UC Berkeley are setting new guidelines after lifting a party ban that was voluntarily in effect over the weekend.
Sorority and fraternity members from Greek Row met behind closed doors over the weekend to come up with new party standards.
The council voluntarily placed a ban on parties after two women were sexually assaulted at Greek events off campus last week.
Party guests will be given new guidelines about what "consent" means when entering parties.
Under the new rules, every house must have three sober members on-call to report to the council at every party or event. Hard alcohol is also banned from the parties. Anyone caught with hard alcohol will be fined up to $20 per member.
A student who is pledging into a fraternity and new to Greek life said the new rules sends the right message about preventing sexual assault on campus.
"You know you can't get away with it," student Yahn Bruggeman said.
A representative from the Interfraternity Council said it is unclear how long the new rules will last.
