Rent control (and the closely related “rent stabilization”) refers to state or local laws that cap how much and how often rent can be increased on covered units, often paired with added tenant protections such as limits on ending a tenancy without cause. Where these laws exist, they typically apply only to certain units — coverage can depend on a building’s age, size, type, or location.
Rent regulation is highly localized. Many areas have none at all, some states expressly prohibit it, and where it does exist the caps, coverage, and exemptions differ from place to place and change over time. Because of that, it’s important not to assume how it applies to a given unit. Rules vary by jurisdiction and change over time — check your local law, and treat this as general education, not legal advice.
