Landlord wants to increase rent with only 30 days notice

Basically my landlord is tryna raise my rent by $100 all because I haven’t been home. I’m not on the lease but from what I know I would need 90 days notice for a rent increase and 60 days if I want to move out. We live under the same roof and she’s always been considered my landlord but now she’s calling herself my roommate to make this ok. Is she allowed to do that? Any help would be nice
