Cannabis in a rented Swiss home: neighbours, damage and termination

Narcotics law and tenancy law need separate assessments. A product’s legal status does not, by itself, determine what disturbance neighbours must tolerate.

TL;DR: Tenants must take care of the property and show consideration for other residents. Odour, damage and contractual breaches can matter under tenancy law. There is no general two-warning rule or automatic immediate termination for every cannabis allegation.

Product status and consideration for others

Article 257f of the Code of Obligations requires care and consideration. Even a product that is not classified as a prohibited narcotic can cause a dispute through smoke or odour. Conversely, a lease cannot make conduct lawful under narcotics law. Saying that CBD presents no legal issue in a rented home overlooks these separate questions.

Establish the actual disturbance

The facts matter: how often does the disturbance occur, which rooms are affected and what has already been communicated? Take specific complaints seriously and seek a remedy that protects other residents. “Cannabis smell” alone does not replace an assessment of the circumstances. Nor is there a fixed number of complaints that automatically ends every tenancy.

Alterations and damage

Building alterations, moisture, electrical installations and damage can raise additional duties. The lease, permissions and actual cause of damage need examination. Insurance coverage depends on the particular policy terms. A blanket promise of coverage or blanket exclusion would be unreliable; the product name alone cannot answer the question.

Termination and deadlines

Under Article 257f(3), continuing breaches of care or consideration despite a written warning can, subject to further conditions, permit termination. For residential premises, that provision requires at least 30 days’ notice ending at the end of a month. It is not a general right to immediate eviction. A tenant seeking to challenge termination must generally apply to the conciliation authority within 30 days of receiving notice. Have the document checked promptly.

FAQ

Are two warnings always required?

No. There is no general two-warning rule. The reason for termination, statutory conditions and particular facts determine the position.

Does a police visit automatically justify termination?

No. A visit does not replace examination of the facts and tenancy-law conditions. Criminal and tenancy issues need separate assessments.
