Vacancy control is a rent regulation policy that limits how much a landlord can charge for a unit even after the previous tenant moves out. In most rent-controlled cities, landlords can reset the rent to market rate when a unit becomes vacant. Vacancy control removes that option, keeping the rent capped for the next tenant as well. It is one of the most debated provisions in housing policy because it determines whether rent protections follow the tenant or stay attached to the unit itself.
Vacancy Control vs. Vacancy Decontrol
These two terms describe opposite approaches to what happens when a rent-regulated apartment turns over. Under vacancy decontrol, the landlord can raise the rent to whatever the market will bear once a tenant leaves. The regulated price effectively resets. Under vacancy control, the landlord is still bound by the regulated rent, typically allowed only a modest increase tied to a measure like the Consumer Price Index before listing the unit again.
Most rent stabilization systems in the United States use vacancy decontrol. That means the protections largely benefit long-term tenants. Once they leave, the unit re-enters the open market. Vacancy control, by contrast, treats the price cap as a permanent feature of the unit regardless of who lives there.
How Vacancy Control Works in Practice
In jurisdictions with vacancy control, the allowable rent for a vacant unit is usually calculated as the previous tenant’s rent plus a fixed percentage increase. Nearly all rent-regulated jurisdictions set that annual increase as a percentage of existing rent, sometimes indexed to inflation or a consumer spending measure. So if a tenant paying $1,500 per month moves out and the allowable annual increase is 3%, the landlord could list the unit for roughly $1,545, not for the $2,200 that comparable unregulated apartments might command.
This stands in sharp contrast to what happens without vacancy control. In New York City before the 2019 reforms, landlords could deregulate a rent-stabilized unit entirely once the rent reached $2,774.76 per month and the unit became vacant. At that point, the apartment left the regulated system for good, and the next tenant paid market rate. That mechanism steadily shrank the city’s stock of affordable, regulated housing over the course of decades.
Where Vacancy Control Exists (and Where It Doesn’t)
Vacancy control is rare in the United States. California’s Costa-Hawkins Rental Housing Act, passed in 1995, explicitly banned it statewide. Before the law took effect, five California cities had vacancy control ordinances: Berkeley, Cotati, East Palo Alto, Santa Monica, and West Hollywood. Costa-Hawkins overrode all of them, establishing that property owners may set a new rental rate whenever a former tenant voluntarily vacates or is lawfully evicted. Proponents of the law described it as “a moderate approach to overturn extreme vacancy control ordinances which unduly and unfairly interfere into the free market.” Attempts to repeal Costa-Hawkins have failed at the ballot box twice, in 2018 and 2020.
New York moved in the opposite direction. The Housing Stability and Tenant Protection Act of 2019 eliminated vacancy decontrol for rent-stabilized apartments. Owners can no longer remove a unit from rent stabilization after a vacancy, regardless of what the rent has reached. The law also eliminated the “vacancy bonus,” a provision that had let landlords tack on a significant percentage increase between tenants. These changes effectively brought New York closer to a vacancy control framework, though the city still allows some rent adjustments at turnover set by the Rent Guidelines Board.
In Canada, most provinces do not have vacancy control. Ontario, for example, caps annual rent increases for existing tenants but places no legal limit on how much a landlord can raise the rent when a new renter moves in. British Columbia is a notable exception: it introduced vacancy control provisions that restrict rent resets between tenancies.
The Case for Vacancy Control
The core argument is straightforward: without vacancy control, landlords have a strong financial incentive to push existing tenants out. If a landlord can reset the rent to market rate the moment a unit is vacant, every long-term tenant paying below-market rent represents lost revenue. That creates pressure, sometimes through neglect, buyout offers, or in worst cases, illegal eviction. Where vacancy decontrol is the rule, tenant advocates point to exactly this dynamic as a driver of displacement in gentrifying neighborhoods.
Vacancy control also preserves the total number of regulated units over time. New York’s experience before 2019 illustrates the erosion that can happen without it. Each time a stabilized apartment’s rent crossed the deregulation threshold and the tenant left, the unit permanently exited the system. Over years, tens of thousands of apartments were lost from the rent-stabilized stock this way, with no mechanism to replace them.
The Case Against Vacancy Control
Critics argue that vacancy control discourages landlords from maintaining and improving their properties. If you can never raise the rent to reflect the true cost of renovations or the market value of an upgraded unit, the financial logic of investing in the building weakens. Research on strict rent control in Cambridge, Massachusetts, found that rent-controlled buildings were 8 percentage points more likely to convert to condominiums than comparable unregulated buildings. That led to a 25 percentage point reduction in the number of renters living in those units relative to 1994 levels, as landlords pulled apartments out of the rental market entirely.
There is also the black market problem. Where vacancy control keeps rents far below market rates, informal and sometimes illegal transactions can emerge: tenants subletting at a markup, exchanging keys for under-the-table payments, or refusing to leave units they no longer occupy because the below-market rent is too valuable to give up. These side effects can make housing markets less transparent and harder to regulate.
Economists also raise concerns about housing supply. If landlords expect returns to be permanently capped, they may convert rental buildings to condos, let properties deteriorate, or simply exit the rental market. Cambridge’s experience showed a 15 percentage point decline in the number of renters living in formerly regulated buildings after rent control was repealed, driven partly by condo conversions that had already been set in motion during the control period. New construction was exempt from Cambridge’s rent control rules specifically because legislators recognized the risk of discouraging development.
Why the Debate Keeps Resurfacing
Vacancy control sits at the center of a tension that housing policy has never fully resolved. Tenant protections that are too weak let rents spiral during housing shortages, displacing the people regulation was designed to help. Protections that are too strong can shrink the supply of rental housing, creating different shortages. The policy tradeoff is real, and it plays out differently depending on how tight a local housing market already is.
New York’s legislature continues to revisit vacancy-related provisions. A 2025 state senate bill (S8319) proposed extending rent stabilization concepts to commercial spaces, motivated partly by a rise in vacant storefronts, which climbed from 4% in 2007 to over 11%. In California, repeated legislative efforts have tried to amend or repeal the Costa-Hawkins Act’s ban on vacancy control, though none have succeeded. The question of whether rent caps should follow the unit or the tenant remains one of the most contested issues in American housing policy.
