Short answer
At a glance: 60 days
Rent increase: 60 days' written notice where there is no written lease; no more than one increase in any 12 months
Notice: At least 60 days before the rent increase takes effect
If there is no written lease, give at least 60 days' notice before raising the rent. For any tenancy, written or not, the rent may be increased only once in any 12 consecutive months the tenant occupies the unit.
