Generally, there isn't any grace period for paying rent unless either the lease states that there is a grace period or the landlord has a policy which may not be in the lease but allows for a grace period.For example, if the lease says, rent is due on the first of the month and is late if not paid by the fifth of the month, this language indicates that there is a grace period.  Another example is if the lease doesn't mention a grace period, but the landlord has a policy which states that rent is due on the first of the month, and is late if not paid by the fifth of the month.
