She “is now confined to the interior premises" of her L.A.-area home at all times.

Lindsay Lohan has begun serving house arrest at her Venice, Calif., townhouse.

L.A. Sheriff's spokesman Steve Whitmore tells People the actress, 24, “is now confined to the interior premises of her home at all times,"

She surrendered to the Lynwood Jail Thursday at 5:02 a.m., was fitted with an electronic ankle bracelet and released less than an hour later after it was determined she was eligible for home confinement.

Lohan - who pleaded no contest to stealing a $2,500 necklace - could serve a little over two weeks of confinement due to good behavior.

She also is serving 480 hours of community service, which includes work at both a women's shelter and janitorial duty at the L.A. County morgue.

Speaking recently to Jay Leno, Lohan (who is soon set to film Fiore Films’ upcoming Gotti movie) said, “I've made a lot of poor decisions and I'm dealing with the consequences.'
