If you're convicted for petit larceny your sentence is up to 1 year in jail. So if someone is released pretrial and he gets re-arrested for petit larceny, judges can still sentence that person to jail time.

Also, since the bail reform amendments that took effect in July 2020, judges can set bail on cases involving harm to person or property if the person has a pending case that also involves harm to a person or property. So if someone is arrested for petit larceny and released without bail, and then they get re-arrested for another petit larceny charge, the judge is allowed to set bail.
