The rental deposit — or security — is a financial security mechanism designed to protect the landlord against potential tenant defaults at the end of the lease. Under Swiss law, it is strictly governed by art. 257e CO, which sets the statutory cap, the form of deposit and the conditions for release. PBM Avocats accompanies tenants and landlords on all matters relating to the rental deposit in Geneva and Lausanne.
The Legal Framework of the Rental Deposit (Art. 257e CO)
Art. 257e CO governs the rental deposit under Swiss law. This provision primarily protects the tenant by limiting the deposit amount and imposing strict conditions for its release.
| Aspect | Statutory rule | Legal basis |
|---|---|---|
| Maximum amount (residential lease) | 3 months' net rent | Art. 257e para. 1 CO |
| Form of deposit | Blocked bank account in tenant's name | Art. 257e para. 2 CO |
| Owner of the funds | The tenant (interest accrues to them) | Art. 257e para. 2 CO |
| Release in favour of landlord | Tenant's agreement or court order | Art. 257e para. 3 CO |
| Release in favour of tenant | Landlord's agreement or court order | Art. 257e para. 3 CO |
| Sanction for exceeding the cap | Nullity of the excess clause | Art. 257e para. 1 CO |
Forms of Rental Deposit in Switzerland
1. The Bank Guarantee Account (Classic Statutory Form)
The standard statutory form is a cash deposit in a blocked bank account opened in the tenant's name at a Swiss bank. The tenant provides the landlord with a bank certificate confirming the deposit and blocking of funds. This account generally earns interest at the savings rate, and interest accumulates in favour of the tenant throughout the lease.
2. Surety Insurance (Private Alternatives)
Private products such as Firstcaution, SwissCaution, CautionPlus or guarantees offered by banks allow the tenant to avoid tying up capital. In exchange for an annual premium (generally 3 to 5% of the guaranteed amount), an insurance company or bank acts as guarantor towards the landlord. These products are not expressly provided for by art. 257e CO but are widely accepted in practice.
| Type | Advantage | Disadvantage |
|---|---|---|
| Blocked bank account | Capital recovered at end, interest earned | Capital tied up (1-3 months' rent) |
| Surety insurance | No capital tied up | Annual premium lost (non-recoverable) |
| Bank guarantee | Flexible, widely accepted | Variable annual cost |
Return of the Rental Deposit
The return of the deposit at the end of the lease is a crucial step that gives rise to many disputes. The procedure is as follows:
- Handover of keys: the tenant returns the keys on the agreed date
- Exit inspection: the landlord inspects the dwelling and notes any defects
- Settlement period: the landlord has a reasonable period to identify their claims
- Agreement or dispute: if the parties agree, the bank releases the funds according to instructions; in case of disagreement, one of the parties applies to the court
Limitation Period
Claims by the landlord arising from the lease are subject to a 10-year limitation period (art. 127 CO). However, damage noted at the exit inspection must be reported immediately to avoid being time-barred (art. 267a CO). In practice, landlords have a few weeks to quantify their claims.
In Case of Refusal to Release
If the landlord refuses to release the deposit or to give consent without valid reason, the tenant may:
- Send a formal written notice to the landlord
- Apply to the rental conciliation authority
- If conciliation fails, apply to the Rental Court to obtain a decision ordering release
Conversely, if the tenant refuses to give consent despite legitimate claims by the landlord, the latter may take legal action to obtain a decision authorising deduction from the deposit.

Frequently Asked Questions on the Rental Deposit in Switzerland
What is the maximum amount of the rental deposit in Switzerland?
For residential leases, the rental deposit (security) is capped at 3 months' net rent (excluding charges) by art. 257e para. 1 CO. Any contractual provision exceeding this cap is null and void. For commercial leases, no statutory cap is provided by the Code of Obligations, but the security demanded must not be disproportionate. In Geneva and the canton of Vaud, market practice for commercial leases varies between 3 and 6 months' rent.
In what type of account must the rental deposit be held?
The deposit must be held in a blocked bank account opened in the tenant's name at a Swiss banking institution (art. 257e para. 2 CO). This account is blocked in favour of the landlord for the duration of the lease. The tenant remains the owner of the funds, meaning that the interest accrues to them. Upon expiry of the lease, the funds may only be released with the written agreement of both parties or by court order. Alternative products such as surety insurance (Firstcaution, SwissCaution, etc.) exist but are not expressly provided for by law.
How can one recover the rental deposit at the end of the lease?
After the handover of keys and the exit inspection, if the landlord has no valid claims, they must give their written agreement to the bank to release the funds in favour of the tenant. If the landlord refuses without valid reason, the tenant may apply to the conciliation authority and then to the court to obtain a decision ordering the release of the deposit. In practice, the bank releases the funds upon receipt of both parties' agreement or an enforceable court decision.
Can the landlord withhold the deposit for any reason?
No. The landlord may legitimately claim the deposit only for specific reasons: unpaid rent and charges, damage to the dwelling exceeding normal wear and tear noted at the exit inspection, reinstatement or cleaning costs not carried out by the tenant. They cannot withhold the deposit for a mere difference of opinion on the state of the dwelling or for reasons unrelated to the lease. If the landlord abusively refuses to release the deposit, the tenant can obtain a rapid court decision.
What happens if the landlord does not return the deposit within the time limits?
If the landlord delays releasing the deposit without valid reason, the tenant may send them a formal notice, then apply to the conciliation authority. If conciliation fails, the court may order the landlord to release the deposit and pay default interest (5% per annum, art. 104 CO) from the date of formal notice. The landlord may also be ordered to pay costs if their refusal is deemed unjustified. PBM Avocats intervenes effectively to recover unduly withheld deposits.
