The content of this website serves the technical preliminary review of possible rent adjustments under Swiss tenancy law. Despite careful implementation, we assume no liability for completeness, currency, or correctness in any individual case.
mietzins-senkung.ch does not replace legal advice in individual cases or consultation with a tenants' association or conciliation authority. The calculations and rent-reduction requests produced are technical tools based on the data confirmed by the user.
For the reference interest rate and calculation logic, publicly accessible information from the Federal Housing Office (BWO) and published pass-through rates are used.
