Resolved: Cities should adopt rent control to address high housing costs.

Rent control limits how fast landlords can raise rents. It protects tenants now, but many economists worry it reduces housing over time. Should cities use it?

Background

Rent control (or rent stabilization) limits rent increases for existing tenants, often to a set percentage a year. Most modern versions are milder than the strict rent freezes of the mid-1900s: they usually allow yearly increases tied to inflation and let rents reset when a tenant moves out. Several states, including California and Oregon, have statewide caps on rent increases, while many states forbid cities from adopting rent control. [2]

A widely cited study of San Francisco’s 1994 expansion of rent control (Diamond, McQuade and Qian, American Economic Review, 2019) found it did what it promised for covered tenants, who were about 20% more likely to stay in their homes and less likely to be displaced from the city. But landlords of covered buildings reduced rental housing supply by about 15%, mainly by selling to owner-occupants or redeveloping, which likely pushed up market rents for everyone else in the long run. [1]

Where the facts themselves are disputed

Do modern rent stabilization laws reduce housing supply?

  • Studies of San Francisco and other places find landlords convert or sell units, shrinking the rental supply.
  • Supporters argue milder modern laws, with exemptions for new construction, avoid most of these effects, and that tenant stability is worth some cost.

Key terms

Rent stabilization
A milder form of rent control that allows regular, limited increases.
Vacancy decontrol
Letting a unit’s rent reset to market rate when a tenant leaves.
Displacement
Tenants being forced to move, often out of their neighborhood, by rising rents.
Supply elasticity
How much the amount of housing changes when prices change.

Both sides at their strongest

Each argument is written the way its best advocates would make it, followed by the strongest answer from the other side. Use them to build your case and to prepare for the other one.

Affirmative

Rent control keeps families in their homes and communities while longer-term fixes take hold.

  1. A1 Rent control prevents displacement.

    Why When rents jump suddenly, tenants must move, sometimes far from jobs, schools and family. Limiting increases lets them stay.

    Evidence Diamond, McQuade and Qian (2019): covered tenants about 20% more likely to stay at their address.

    Best answer The negative answers that the same study found a 15% drop in rental supply, raising rents for everyone not covered.

  2. A2 Stable housing has wide benefits.

    Why Children do better when they don’t change schools often, and long-time residents keep neighborhood ties, local businesses and community groups going.

    Evidence Research on residential stability and children’s outcomes; studies of displacement’s effects on health.

    Best answer The negative replies that these benefits go only to current tenants, while newcomers and young families face higher rents.

  3. A3 Modern rent stabilization avoids old mistakes.

    Why Caps tied to inflation, exemptions for new buildings and rent resets between tenants protect landlords’ returns and keep building going.

    Evidence Design of state laws such as California’s and Oregon’s caps; analyses of exemptions for new construction.

    Best answer The negative argues landlords still respond by converting or selling units, as the San Francisco study found even with exemptions.

  4. A4 Building new housing takes years; tenants need help now.

    Why Even if more construction is the long-term answer, people facing large increases this year can’t wait a decade.

    Evidence Data on permitting and construction timelines; local rent-increase data.

    Best answer The negative replies that targeted rent assistance helps those in need now without discouraging supply.

Negative

Rent control helps some current tenants but shrinks and worsens the housing supply, raising costs for others.

  1. N1 Rent control reduces the supply of rental housing.

    Why When rents are capped, owners have reasons to convert units to condos, sell to owner-occupants or redevelop, removing rentals from the market.

    Evidence Diamond, McQuade and Qian (2019): about a 15% reduction in rental supply among covered buildings.

    Best answer The affirmative answers that well-designed laws can restrict conversions and exempt new construction.

  2. N2 It can raise rents for everyone else.

    Why Fewer rentals on the market means more competition for the units that remain, pushing up rents for newcomers and young people.

    Evidence The San Francisco study’s conclusion that reduced supply likely raised market rents; economists’ surveys on rent control.

    Best answer The affirmative replies that rents were rising fast anyway, and the main cause is too little construction, which rent control doesn’t prevent.

  3. N3 It’s poorly targeted.

    Why Rent control helps whoever already holds a covered unit, regardless of income, while low-income newcomers get nothing.

    Evidence Studies of who lives in rent-controlled units by income.

    Best answer The affirmative replies that many covered tenants are lower-income long-time residents, and means tests could be added.

  4. N4 Better tools address high costs.

    Why Allowing more homes to be built and giving rent assistance to those in need lower costs without discouraging supply.

    Evidence Research on zoning and housing costs; evaluations of housing vouchers.

    Best answer The affirmative answers that zoning reform is slow and vouchers are underfunded, so tenants need protection now.

Strawman or steelman?

A strawman is a weak copy of the other side’s view, easy to knock down and unfair to the people who hold it. A steelman is that view at its strongest. Answer the steelman, and you’ve answered the real argument. (More on steelmanning.)

Affirmative

Strawman “Rent control supporters think landlords shouldn’t make any money.”

Why it’s unfair Modern proposals allow regular increases and exempt new construction.

Steelman Limiting sudden rent increases keeps families in their homes and communities, and modern designs protect landlords’ returns while long-term fixes take hold.

Negative

Strawman “Opponents don’t care if families get evicted.”

Why it’s unfair Many opponents favor rent assistance and building more housing.

Steelman Rent control shrinks the rental supply and raises rents for everyone not covered; building more and targeted assistance help more people.

Weak arguments to avoid

Affirmative

  • “Rent control will make housing affordable for everyone.” It limits increases for covered tenants; it doesn’t lower rents generally.

Negative

  • “Rent control destroys cities, like bombing.” An exaggerated old quip; argue from the studies instead.

Questions for cross-examination

Ask the Affirmative

  1. What did the San Francisco study find about rental supply?
  2. Would new buildings be exempt?
  3. How would your plan help someone moving to the city?

Ask the Negative

  1. What did the same study find about covered tenants staying in their homes?
  2. What should a family facing a 30% increase do this year?
  3. How long does it take to build enough new housing?
