How much notice does a landlord have to give before raising the rent in California?

In California, a landlord must give 30 days written notice before a rent increase of 10% or less, and 90 days before an increase of more than 10%. Every increase in the previous twelve months counts toward the 10%. This is Cal. Civ. Code §§ 827, 1946.1, 1954; CCP § 1161.
