Los Angeles Superior Court Judge Patricia Schnegg set the amount Friday evening. As conditions of bail, Lohan must wear a SCRAM alcohol-monitoring device and have it in place within 24 hours of her release. She is also prohibited from possessing any controlled substances, must refrain from drinking and must stay out of places where alcohol is primarily sold.
It is unclear when Lohan could be released.
Earlier Friday, Lohan was whisked from a Beverly Hills court after /*Los Angeles Superior Court Judge Elden S. Fox*/ said she should be held without bail until an Oct. 22 hearing.
The judge's decision came after the 24-year-old star failed a court-ordered drug test after being released from rehab last month.
Lohan was in court for only 10 minutes. The actress looked stunned when the judge refused to hear arguments from her lawyer for bail. Lohan left in handcuffs from a side entrance, hiding behind a blanket.
Schnegg's ruling states that defendants are entitled to bail in misdemeanor cases, which applies to Lohan.
The "Mean Girls" star admitted publicly on her /*Twitter*/ account last week to failing a court-mandated drug test.
Both of /*Lohan*/'s parents were in court. Her father said he is devastated that his daughter is going back to jail.
"She hasn't gotten help for her addiction yet. She doesn't make the right decisions. She doesn't know better," said /*Michael Lohan*/.
Lohan admitted on Twitter that she had an addiction problem, saying it is a disease and it doesn't go away overnight.
This is Lohan's third jail stint for a three-year-old drug and drunken driving case filed after a pair of high-profile arrests in 2007. She spent 14 days in the Lynwood Correctional Facility on a 90-day sentence earlier this summer. In 2007, the actress spent just 84 minutes in jail.
On Friday, Lohan was booked into the same facility.
"This is not a sentence. She has been remanded with no bail to wait for her probation-violation hearing," said Steve Whitmore of the /*Los Angeles County Sheriff's Department*/.
This was Lohan's first appearance before Judge Fox, who agreed to release the actress early from rehab last month.
Fox had laid out a strict treatment and monitoring program and said he would sentence Lohan to a month in jail for each drug test she skipped or failed.
He didn't say during the hearing what drug caused Lohan to fail the drug screen, saying only that she tested positive for a "controlled substance."
Lohan is still on probation for previous DUI charges.
