Dr. iur. Alexander Schiemenz, LINDEMANNLAW — FuW Opinion Article, June 2026
Those who cap rents do not build housing. They redistribute scarcity. That is precisely the problem with the wave of housing policy regulation currently sweeping through Switzerland. On June 14, Zurich will vote on the Housing Protection Initiative. Basel has already shown what follows. Bern, Geneva, and Vaud are examining similar rules. What looks like cantonal social policy is in fact a directional decision on housing policy for the entire country — a Switzerland heading towards ten million people.
The diagnosis is correct: in cities with low vacancy rates, rising construction costs, and sustained immigration pressure, housing has become a matter of distribution. Affordable housing is a legitimate political goal. The means, however, is open to debate.
“The price is not the cause of the housing shortage. It is its symptom. Those who regulate only the price are fighting the thermometer instead of the fever.”
The Politically Attractive Fallacy
Rent caps have one great advantage: they are easy to explain. High rents — so let us limit them. That is catchy, emotionally plausible, and referendum-ready.
Economically, it is too simplistic. The price is not the cause of the housing shortage. It is its symptom. High rents indicate that too few homes exist where people want to live. Those who regulate only the price without increasing supply are fighting the thermometer instead of the fever.
In the short term, rent caps can relieve individual households — that is undisputed. In the medium term, they set the wrong incentives: fewer investments, fewer renovations, more bureaucratic procedures, more evasive manoeuvres. In the end, there are not more affordable apartments, but fewer available ones.
Basel Warns
Basel-Stadt provides the cautionary example in real time. Since 2022, strict housing protection rules have been in force. The result: declining renovation contracts, new permit procedures, litigation risks, and multi-year monitoring periods. Some rules already had to be relaxed as of November 2025 because renovations were being suppressed too severely.
The numbers speak clearly. Under the simplified housing protection procedure, the return on construction costs for a renovation drops to 1.3 percent, compared to 2.7 to 3.4 percent under standard Swiss tenancy law. At today’s interest rates, regulatory requirements, and construction costs, no one renovates for 1.3 percent. This is not an accident. It is the predictable outcome of a system that makes investment more difficult and politically caps returns.
Energy-efficient renovations, building technology upgrades, comprehensive refurbishments — precisely what climate targets require — are no longer financially viable. A house frozen in place by regulation is not more social. It is just older.
Build, Don’t Block
The core social policy flaw of the rent cap lies in its targeting. It does not primarily help those most in need. It helps those who already have access to the regulated housing stock.
Those who have an affordable regulated apartment stay put. Even if it has become too large. Even if they change their place of work. Every move becomes a financial penalty, because the new rent will be higher. This creates lock-in effects: individuals in family apartments, families without access to larger units, declining professional mobility. Existing housing is used less efficiently.
The right answer is more supply: faster permitting, denser building, activating development sites, and shortening procedures. And a different mindset towards building is needed. A Switzerland with ten million people is not a spatial planning threat — it is a design challenge. 15-minute neighbourhoods, positive-energy buildings, new mobility concepts: these are already being built today, in Rotkreuz, in Hamburg, in Copenhagen. It is not land that is lacking. It is investment security.
Social goals can be achieved more precisely: non-profit housing construction, targeted housing allowances, development area rules with calculable returns. The counter-proposal to the Zurich initiative points in this direction.
The housing shortage is real. That is precisely why it should not be answered with symbolic politics. A rent cap does not create a single additional square metre of housing. It increases procedural costs, slows down renovations, and shifts the scarcity onto those who do not yet have an apartment. What looks like protection is the management of scarcity with a social label.
Rent caps don’t solve Switzerland’s housing shortage – they worsen it. Why permit reform and investment security are the right answers to the housing crisis.
