I am 19 and my dad is giving me a week to find a new place because I won't comply with his rules. Is it legal for him to do that

Parents have a duty of support until you are emancipated, usually at 18 yrs of age.  Are you still in high school?  Or graduated and have a job. Or married and/or living with someone? Key questions to show whether you are emancipated in the eyes of the law. If so, he can usually throw you out.  Many exceptions to the rule. Disabled, for example.
