FAFSA on campus/off campus selection

So I’ve been accepted to UCR,UCSD, USCB and CSUN and on my fafsa I put on campus housing but now that I’m considering UCSD, I think I would live off campus. Since they posted their decisions so late, I haven’t received a financial aid package from them yet but I’m wondering if I have to notify FAFSA that I’d rather live off campus? Do I have to notify the school? SOS
