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.
In California, rent control laws vary by municipality, with some cities having strict rent control measures while others do not. The state allows local governments to enact rent control, unlike many other states that prohibit such measures. California's statewide rent control was strengthened by the Tenant Protection Act of 2019 (AB 1482), which caps annual rent increases at 5% plus the local rate of inflation, or 10% (whichever is lower), for most properties that are over 15 years old. This law also provides 'just cause' eviction protections to tenants who have resided in a property for over a year. However, there are exemptions, such as single-family homes owned by individuals and duplexes where the owner lives in one of the units. It's important to note that local ordinances may impose stricter controls, so tenants and landlords should check the specific regulations in their city or county.
