The question of pets in rented accommodation is a recurring source of tension between tenants and landlords in Switzerland. Swiss tenancy law does not prohibit keeping animals, but allows landlords to regulate it contractually, within the limits set by case law. PBM Avocats sets out the rights and obligations of each party in Geneva and Lausanne.
The Legal Framework: Between Contractual Freedom and Case Law Limits
Swiss law contains no specific provision on pets in residential leases. The applicable regime derives from the general rules of the Code of Obligations on contractual freedom, the semi-mandatory provisions of tenancy law and Federal Supreme Court case law on ordinary use of the dwelling.
The central principle is that of ordinary use of the dwelling: the tenant may use the accommodation as a reasonable person would. Case law has progressively defined which animals fall under this ordinary use — and therefore do not require the landlord's consent — and which require explicit contractual authorisation.
| Type of Animal | Ordinary Use? | Landlord's Consent Required? | Prohibition Clause Valid? |
|---|---|---|---|
| Aquarium fish | Yes | No | No (clause null) |
| Caged birds (canaries, budgerigars) | Yes | No | No (clause null) |
| Hamsters, dwarf rabbits, guinea pigs | In principle yes | Generally no | Debatable |
| Cats | No (per Federal Supreme Court) | Yes if clause in lease | Yes |
| Dogs | No | Yes if clause in lease | Yes |
| Exotic / dangerous animals | No | Yes (refusal generally legitimate) | Yes |
The Pet Clause in the Lease
Many lease agreements in Switzerland contain a clause making the keeping of pets subject to prior consent from the landlord. The validity and scope of this clause depend on its wording:
Prior Consent Clause
A clause stipulating that "keeping animals is subject to prior consent from the landlord" is in principle valid for cats and dogs. It obliges the tenant to request authorisation before acquiring the animal. The landlord may refuse, but this refusal must be based on objective and reasonable grounds:
- Risk of nuisance for other tenants in the building
- Co-ownership regulations prohibiting animals
- Documented allergies of neighbours or the landlord
- Potentially dangerous nature of the breed
- Building without suitable outdoor space
Absolute Prohibition Clause
A clause prohibiting any animal without exception is partially null insofar as it applies to animals whose keeping constitutes ordinary use of the dwelling (small animals, fish, caged birds). For dogs and cats, an absolute prohibition is contestable but may be valid if justified by reasons specific to the building.
Nuisances Caused by Animals
Keeping an animal, even when authorised, may engage the tenant's liability if it causes excessive nuisances to other occupants of the building:
- Repeated or continuous barking (noise disturbance)
- Persistent odours affecting common areas or neighbouring dwellings
- Bites or aggression towards other occupants or their animals
- Fouling of common areas
In the event of proven nuisances, the landlord may:
- Send the tenant a formal notice to cease the nuisances
- Withdraw the previously granted authorisation (if the nuisances justify withdrawal)
- Terminate the lease on an extraordinary basis for serious breach of tenant obligations (art. 257f CO), after a formal notice that has had no effect
Damage Caused by Animals and the Rental Deposit
At the end of the lease, the landlord may retain from the rental deposit amounts corresponding to damage caused by the tenant's animals, to the extent that it exceeds normal wear and tear:
- Deep scratches on parquet flooring or tiles
- Carpet damaged or heavily odoured
- Wallpaper or paintwork scratched or soiled
- Pest control treatments required by flea infestation
- Special cleaning costs to eliminate persistent odours

Frequently Asked Questions About Pets in Rental Properties in Switzerland
Can a landlord prohibit pets in a lease agreement?
Yes, but not absolutely. A clause prohibiting all pets without exception is null with regard to small animals (fish, caged birds, hamsters, etc.) which Federal Supreme Court case law assimilates to ordinary use of the dwelling not requiring the landlord's consent. In contrast, a clause prohibiting dogs and cats is in principle valid. PBM Avocats analyses the exact scope of the clause in your lease.
Must the tenant obtain the landlord's permission to have a dog or cat?
It depends on the contract. If the lease contains a clause making the keeping of pets subject to the landlord's consent, the tenant must indeed obtain prior consent. The landlord may refuse, but this refusal must not be arbitrary: it must be based on objective reasons (risk of nuisance for other tenants, co-ownership regulations, documented allergies, etc.). A systematic and unjustified refusal can be challenged. In the absence of a clause, the tenant is in principle free to keep ordinary animals.
What are the landlord's rights if a tenant keeps an unauthorised animal?
If the tenant keeps an animal in violation of a valid lease clause, the landlord may send them a written formal notice requiring them to part with the animal within a reasonable period. If the tenant refuses, the landlord may terminate the lease on an extraordinary basis (art. 257f CO — serious breach of obligations), after a formal notice that has had no effect. However, this termination is subject to a minimum notice period of 30 days for dwellings. Courts examine the proportionality of the sanction.
What should one do if a neighbouring tenant has an animal causing nuisance?
Nuisances caused by an animal (excessive barking, odours, aggression) may constitute neighbourhood disturbances within the meaning of civil law (art. 684 CC). The tenant suffering the nuisance must first inform the landlord in writing, requesting intervention with the offending tenant. If the landlord does not take effective measures, they may be held responsible for the nuisances suffered by their tenant. Rent reduction and extraordinary termination may be considered if the nuisances are serious and persistent.
Is the tenant responsible for damage caused by an animal?
Yes. The tenant is responsible for damage caused by their animals to the rented accommodation (art. 267 para. 1 CO). Such damage must be recorded during the exit inspection and goes beyond normal wear and tear: significant scratches on the parquet, carpet damage, persistent odours requiring special treatment, damage to walls or doors. The landlord may deduct the cost of repair from the rental deposit, or even take legal action for damages if the deposit is insufficient.
