Rent Stabilized vs Rent Controlled — What's the Actual Difference?
The two terms get used interchangeably, but they protect tenants in very different ways. Here's a plain-English breakdown.
The short answer
Rent control freezes or strictly limits rent on specific apartments — usually pre-WWII units in major cities — and is increasingly rare. Rent stabilization caps how much rent can rise each year on a much broader pool of apartments and is the dominant model today.
If your apartment is described as 'rent stabilized', your rent can go up — but only by the amount your local rent board decides each year (often 2–5%).
If it's described as 'rent controlled', your rent often barely moves at all, and the protection usually transfers only to certain successors (a spouse, sometimes a long-term roommate).
Where you find each
True rent control survives mainly in New York City, parts of Los Angeles, and a handful of New Jersey municipalities — almost always for very long-term tenants in pre-war buildings.
Rent stabilization is far more common: it covers most pre-1974 NYC buildings with 6+ units, most pre-1979 LA buildings, much of San Francisco, parts of Oakland, Berkeley, St. Paul, Newark, Jersey City, and (statewide) Oregon and now Washington.
What this means for your increase
If you're in a stabilized unit, the legal increase for the year is published — you don't have to negotiate it. If your landlord is asking for more, they're almost certainly out of bounds.
If you're in a rent-controlled unit, the rules are even tighter — increases are usually limited to a small CPI-based adjustment or none at all.
If you're not sure which (or neither) applies to you, run your numbers through the tool — we'll flag the most likely scenario and what to ask your landlord for in writing.
