Iowa Rent Increase Notice Requirements (Sec. 562A.34)

Iowa's Uniform Residential Landlord and Tenant Law does not limit how much a landlord may raise rent or impose a specific rent-increase notice statute. Because rent for a month-to-month tenancy can only change at the start of a new periodic term, landlords generally tie an increase to the termination rule in Iowa Code Sec. 562A.34(2): a month-to-month tenancy may be ended 'by a written notice given to the other at least thirty days prior to the periodic rental date specified in the notice.' A tenant who rejects the new rent may give the same 30-day notice and move out. During a fixed-term lease, rent cannot be raised before the term ends unless the lease itself allows it.

No specific statutory penalty for the increase itself. An increase imposed mid-term without lease authority, or with less than the 30-day notice tied to ending a month-to-month tenancy, is unenforceable.
