Summary
Rental permits are a city job, not a county one. Iowa City runs a mandatory rental-permit program with a two-year inspection cycle through its Housing Inspection Services, and Coralville and North Liberty require permits too. State law now limits how far a city can push occupancy and permit caps.
A city shall not, after January 1, 2018, adopt or enforce any regulation or restriction related to the occupancy of residential rental property that is based upon the existence of familial or nonfamilial relationships between the occupants of such rental property.
Full Breakdown
Johnson County has no rental registry for its incorporated cities, which each run their own. Iowa City, driven by its huge University of Iowa student-rental market, requires a rental permit for every rental unit and inspects on a two-year cycle, checking life-safety, fire-safety, and maintenance; permit fees run about $150 per building plus $17 per unit and $7 per bedroom. Coralville and North Liberty operate similar permit-and-inspection programs. State law now curbs these: Iowa Code section 414.1 bars a city from limiting occupancy based on familial or nonfamilial relationships (ending the old three-unrelated rule) and from capping rental permits on single-family homes or duplexes, and tenants have challenged warrantless inspections.
Violations & Fines
Renting without a required city permit draws fines and correction orders under the local housing code, and a failed inspection triggers a re-inspection. A permit cap on a single-family home or duplex is void under section 414.1.
