A bill for an act relating to property law by modifying provisions related to landlord and tenant law and forcible entry and detainer actions, and including effective date provisions.

SF 421 amends Iowa's landlord-tenant laws to clarify notice requirements, strengthen tenant protections, and update eviction procedures. It specifies that mail notices are deemed delivered four days after mailing (Sections 2, 5), defines "rent" to include utilities and late fees (Section 1), and makes prohibited rental terms unenforceable with tenant remedies for damages (Sections 3, 6). The bill also requires notices to be posted at the property entrance and mailed, with records sealed for residential eviction cases under specific conditions (Sections 4, 7, 11). These changes directly affect tenants and landlords by standardizing communication, limiting unfair terms, and creating record-sealing options for tenants after eviction judgments.
