A bill for an act relating to rent increases under residential landlord and tenant rental agreements and in manufactured home communities and mobile home parks.

HF 2551 limits how much landlords can raise rent for current tenants in Iowa residential rentals and mobile home parks. It sets a cap: rent increases cannot exceed either the Midwest region's consumer price index (CPI) increase or the county-assessed property value increase over the past year, whichever is higher. Landlords must provide written notice of any increase at least 90 days before it takes effect, and the new rent cannot start before the current lease ends. This directly affects existing tenants in both standard housing and manufactured home communities.
