California Rent increase notice

How much notice does a landlord need to give to raise the rent in California?

Periodic (e.g., month-to-month) tenancies: written notice at least 30 days before the effective date if the increase, alone or combined with other increases in the prior 12 months, is 10% or less. Larger increases require a longer notice under § 827(b)(3).
