Private housing
Maximum three months' gross rent (including utilities). A higher demand from the landlord would be legally invalid. In practice, most landlords request between two and three months' rent.
The rental deposit is a security that the tenant deposits in favour of the landlord. It serves as protection against outstanding claims after the end of the lease – particularly for unpaid rent, unsettled utilities or damage to the rented property beyond normal wear and tear.
The deposit serves the landlord as a guarantee for all claims arising from the lease. This mainly includes:
The rental deposit is governed by the Swiss Code of Obligations under Art. 257e CO. The main legal provisions:
The amount of the rental deposit depends on the type of lease and is specified in the rental agreement.
Maximum three months' gross rent (including utilities). A higher demand from the landlord would be legally invalid. In practice, most landlords request between two and three months' rent.
For commercial premises, there is no legal limit. The amount must however be reasonable. Six months' rent is often standard. The financial stability and creditworthiness of the business are decisive factors.
In Switzerland, tenants and landlords primarily have three common methods available.
The tenant deposits the full deposit amount into a special blocked account at a bank. The money is locked until the end of the lease.
Tenant's money is locked
An insurance company guarantees the deposit on behalf of the tenant. Instead of a large one-off payment, the tenant pays an annual premium.
No capital locked up
A bank guarantees payment of the deposit amount to the landlord. The tenant pays an annual fee to the bank.
Annual fee to the bank
The rental deposit must usually be deposited before the keys are handed over. Depending on the method chosen, you either pay the amount into a blocked account or take out rental deposit insurance.
During the ongoing lease, the deposit remains unchanged. In the case of a bank deposit, the money is blocked. In the case of insurance, the annual premium is due.
During the handover of the property, the landlord prepares a report. Any defects are documented. The deposit serves as security for justified claims.
If the landlord has no claims, the deposit is released. In the case of a bank deposit, you get your money back. In the case of insurance, the surety bond ends. If claims exist, the landlord can claim the deposit in whole or in part.
With rental deposit insurance from goCaution, tenants don't need to lock up money in a blocked account. Instead, you pay an affordable annual premium starting from CHF 94.50, and the landlord receives an official surety bond certificate with the same legal security.
