What constitutes California state residency?

California state residency is generally determined by a person's physical presence in the state and their intent to remain. To establish residency, individuals must live in California for at least 366 days and demonstrate ties to the state, such as registering to vote, obtaining a California driver's license, or paying state taxes. Additionally, factors like where one works, attends school, and maintains a permanent home can influence residency status. Ultimately, the intent to make California one's primary and permanent home plays a crucial role.
