When does ISF time start on a 45 day sanction

In most cases, the 45 days starts from the time he was taken into custody, not when he physically arrives at the ISF.

So if he is already sitting in county jail waiting to be transferred:

• That time is usually counting toward the 45 days
• The clock does not reset when he gets to the ISF

About “good time” or credits:

• Short sanctions like a 45 day ISF stay typically do not earn additional time off
• The 45 days is usually a flat sanction ordered by parole

What this means practically:

• If he has already been locked up for some time, he may have already completed part of the 45 days
• The transfer to ISF is more about where he serves the time, not when it starts

One thing to confirm:
Policies can vary slightly by state, so he should:

• Ask his counselor or case manager
• Confirm his time credit calculation

Bottom line
The 45 day sentence usually starts when he was picked up, not when he arrives at ISF, and there is typically no extra time off beyond that.
