This paper critically analyses the proposed law for regulating the rental housing market. The swiss tenants have made mostly negative experiences with the rate of return regulation practiced in the last 20 years. Nevertheless, the new law does not address these problems. If the new proposed law were to be enacted, it would probably lead to a significant rise in real rents in the near future. The shortcomings of the proposal are such that it has to be completely revised. We advocate a laissez-faire solution for the contracting of new leases combined with indexation on the CPI for on-going leases. Such a measure would permit a market evolution satisfying both landlords and tenants.
