The case

Despite the new cantonal development plan, which aims to increase the housing supply in Geneva, demand is expected to continue to outpace supply.

The commentary

Already facing a deepening housing affordability crisis, Geneva is expected to experience significant population growth by 2050, with estimates ranging from 70,000 to 150,000 additional residents. The French-speaking canton is increasingly constrained by its limited territory while simultaneously facing Switzerland’s lowest housing vacancy rate and being one of the most densely populated areas in Europe.

The new 2050 development plan, which is due to be discussed next year, will have to address this difficult and seemingly intractable challenge. Three areas with significant housing potential have been identified.

The first, the Praille–Acacias–Vernets (PAV) development area, is expected to provide around 12,000 new homes, although construction will take place over the span of several decades. The second is the suburban area, which could accommodate approximately 25,000 housing units. The third, and by far the most contentious, is the private villa zone, which has the potential to accommodate a further 22,500 homes.

Despite all these efforts, these projections may already underestimate Geneva’s future housing needs, i.e. policymakers will  be faced with an increasingly difficult choice between expanding the housing supply and preserving the canton’s environmental and spatial constraints. Finding a political consensus on how to address this dilemma is likely to prove quite challenging.
