The actress, 24, will be picking up trash, emptying trash bins, mopping floors and cleaning windows and restrooms at the L.A. County Department of Coroner’s facility.
“She’ll be doing basic janitorial work,” Coroner Assistant Chief Ed Winter tells PEOPLE. “She won’t be handling any dead bodies but she’ll certainly see them.”
This won’t be Lohan’s first visit to the downtown Los Angeles morgue. She previously completed a DUI morgue program following her second drunk-driving conviction 2007.
In addition to a four-month jail term, Lohan was also ordered Friday to complete 360 hours of service at the Downtown Women’s Center, a homeless shelter located in L.A.’s Skid Row.
Lohan must enroll in the two programs within a week and has a year to complete them.
Lohan remains free on bail pending an appeal of her sentence, which experts say she has slim chance of winning.
She faces a June 3 trial in her grand theft charge, which was reduced to a misdemeanor on Friday, facing a maximum penalty of an additional year in jail.
