Deadline: At least 45 days before the rent increase takes effect
No rent increase is effective unless the tenant got written notice at least 45 days before it takes effect (a full term for leases of a month or less). Increases are not allowed during a lease term.
Who it covers: For a lease with a term of one month or less, the notice must equal one full lease term. The rent cannot be raised during the term of a rental agreement. A tenant's silence is not agreement.
