Revised transparency rules on rents

On 21 March 2025, the Swiss Federal Council adopted amendments to the Ordinance on the Rent and Lease of Residential and Commercial Premises. The amendments primarily concern the notification of the previous rent for residential leases with the official form in those cantons that have declared such form to be mandatory. Furthermore, the amendments also concern the formal requirements for notifying a rent increase in the case of staggered rents – mere written notification will now be sufficient. The changes will come into force on 1 October 2025.
