Rent control laws limit the amount a landlord can increase rents on existing tenants. Most states have laws that prohibit local governments from enacting rent control measures. But over 180 municipalities in the United States have rent control measures—and all of them are located in California, Maryland, New Jersey, New York, and Washington, D.C.
The state of Oregon has a statewide rent control law that limits annual rent increases to 7% plus the increase in the consumer price index.
Iowa does not have rent control laws that limit the amount a landlord can increase rents on existing tenants. The state has a preemption law that prohibits local governments from enacting rent control measures. This means that no city or county in Iowa can implement rent control ordinances. Landlords in Iowa are generally free to set rental prices at market rates and increase rents as they see fit, subject to any contractual restrictions in the lease agreement and providing proper notice to tenants as required by state law. It's important for tenants to review their lease agreements to understand any provisions related to rent increases. As of the current knowledge cutoff, there have been no changes to this approach, and Iowa remains without rent control regulations similar to those found in states like Oregon.
