It's certainly not jail – visitors, Internet and phone are all allowed – but a source tells PEOPLE the 24-year-old actress still has a few rules to follow, most of which are standard for home confinement:
ALLOWED Leaving home only for medical appointments or to go to the probation department, as long as advance notice is given.
Visitors can come and go without restrictions.
Unlimited phone and Internet use.
NOT ALLOWED Going outside the "interior premises" of the home without prior authorization; that'll set off her ankle bracelet.
Going to work-related events outside the home. (Lohan also can't perform her community service while confined.)
Tampering with the ankle bracelet, which would sound an alarm to her monitors.
