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.
As of my knowledge cutoff in early 2023, Colorado does not have statewide rent control laws that limit the amount a landlord can increase rents on existing tenants. Unlike Oregon, which has implemented statewide rent control, Colorado allows landlords to set rental prices at market rates. However, there has been ongoing debate and legislative proposals concerning rent control in Colorado. It's important for tenants and landlords to stay informed about any local ordinances that may affect rent control in specific municipalities within the state, although historically, Colorado has not been one of the states with municipalities that have enacted rent control measures.
