Swiss housing shortage deepens as vacancy rate falls below 1%

New-build rents in Geneva, Carouge and Écublens average 50% more than rents in existing buildings, according to Asloca. The comparison captures the affordability problem facing tenants even when construction adds homes to the market.

The Swiss Tenants’ Association says development is concentrated at the high end, leaving low and middle-income households with fewer realistic options. As older, cheaper flats leave the market or change hands, households seeking a modest home compete for a shrinking supply. A new apartment may increase the number of available units while remaining beyond the budgets of the people most affected by the shortage.

Asloca has accused some landlords of using the scarcity to demand excessive rents and of breaching legal limits on returns. Its criticism arrives as institutional investors increase their presence in rental housing. Their share, including pension funds, insurers and property companies, rose from about 31% in 2000 to 44% in 2023, according to the figures cited by LeNews.

The pressure reaches every flat size. Two-room homes recorded the steepest proportional decline, down 8.5%. Three-room flats remained the most numerous vacant category, with 13,691 units, followed by 11,929 four-room flats. Those totals offer little comfort to applicants when demand is concentrated in particular cities, price brackets and neighbourhoods.

For tenants, a 0.93% national vacancy rate means a move can become a financial and administrative contest. Applicants may need to respond within hours, assemble salary records and references, and accept higher housing costs to remain near work, schools or family networks.

The consequences are especially serious for low and middle-income households. When cheaper flats are scarce, tenants may stay in homes that no longer suit their household size, accept longer commutes or devote a larger share of monthly income to rent. Families looking for three or four rooms face particular pressure in urban and lakeside markets, where demand is reinforced by employment, transport links and international residents.

A tight supply can also make screening more consequential. Foreign flat hunters have reported discrimination in the Swiss rental market, while applicants without established local records may find it harder to compete. Scarcity gives landlords a larger pool of candidates, increasing the practical importance of documentation, references and speed.

The tenants’ association has urged stronger attention to affordability and legal rent limits. Its argument is that construction policy must measure who can access new homes, not only how many units receive planning approval. For households already searching, the immediate task remains finding a flat before another applicant does.

Switzerland enters the next phase of its housing shortage with fewer vacant homes across nearly every major region. The immediate data points to continued competition, while the longer-term response will depend on the type, price and location of new construction.

The national vacancy rate has declined for six consecutive years. Detached houses and recently built homes are also affected, with 6,496 detached houses and 3,910 homes built within the previous two years vacant on the reporting date. That suggests unused stock exists, but its distribution does not necessarily match where jobs, public transport and affordable rents are found.

Greater Zurich’s slight improvement to 0.52% shows that local conditions can shift, although the region remains tight. Jura and Solothurn offer more vacant homes, yet relocating there may not be practical for people tied to employment or family in Geneva, Zurich, Zug or Lausanne.

The figures put pressure on cantonal planning authorities, municipalities, developers and landlords to deliver homes that ordinary incomes can reach. Asloca’s warning is specific: increasing supply at the expensive end will not resolve the shortage faced by people who cannot pay premium rents. Until more affordable homes appear in the places where demand is strongest, Switzerland’s rental market will remain defined by low choice and high costs.
