The Swiss authorities online
Tenancy law does not cover all aspects of relations between tenants and owners or property managers and is even less specific with regard to relations among neighbours.
Relations between neighbours are defined according to house rules or even on the sole basis of custom. The relevant authority varies depending on the type of disturbance.
Other issues involving neighbours, such as property damage or unpleasant smells, should also be reported to the police. If the problem continues, you can lodge a complaint, which can prevent, eliminate or reduce disturbances to an acceptable degree. Depending on the circumstances, you can claim compensation or damages.
In the event of disputes among neighbours, contact your local conciliation authority.
Landlords’ and tenants’ associations also support landlords and tenants in their specific concerns and interests regarding termination.
If talking directly with the neighbours does not lead to any improvement in the situation, you should ask the landlord or landlady in writing to deal with the disturbance within a reasonable period of time. At the same time, you can mention that you will cease to pay rent if no improvement occurs within the said time limit, withholding the money in a separate account. You can ask for a reduction in rent so long as the disturbance persists.
If the neighbour continues to cause the disturbance despite a written warning from the landlord or landlady, the latter can reduce the period of notice to be given to 30 days to the end of a calendar month.
