Rental Deposit in Switzerland: Amount, Account and Recovery

How much a rental deposit costs in Switzerland

Article 257e of the Swiss Code of Obligations caps the rental deposit for residential premises at three months' net rent, meaning rent excluding ancillary charges such as heating or building services. A clause in a lease that sets a higher amount is void, whatever the parties may have agreed. In practice, most landlords and agencies ask for the full three months, since the law sets a ceiling rather than a fixed amount.

The same article requires that, where the deposit is paid in cash or securities, it be placed in a bank account opened specifically in the tenant's name, not credited to the landlord's own account or business assets. This separation matters: it keeps the money identifiably yours for as long as the tenancy runs, and it means the landlord cannot draw on it freely or treat it as their own funds.

Opening the blocked rental deposit account

Once you have a signed lease, you or the landlord's agency will typically approach a bank to open what is usually called a rental deposit account, sometimes referred to by its German name, Mietzinsdepot, even outside German-speaking Switzerland. Most banks operating in Switzerland offer this type of account, and the process is generally handled locally at a branch rather than online.

You will usually need proof of identity, the signed lease, and the deposit amount to transfer into the account. Processing times vary between banks, so ask early rather than assuming the account will be ready before your move-in date. Once the account is open, the bank issues a certificate or confirmation that is handed to the landlord as proof that the deposit is in place.

• •Approach a bank once the lease is signed
• •Provide identification, the lease and the deposit amount
• •Transfer the funds into the account opened in your name
• •Obtain the bank's confirmation to give to the landlord
• •Keep your own copy of the confirmation for your records

Deposit insurance as an alternative to a cash deposit

Instead of tying up several months' rent in a blocked account, tenants can turn to a rental deposit guarantee, a form of insurance in which a company issues a guarantee to the landlord in exchange for a recurring premium. The landlord accepts this guarantee in place of a cash deposit, and the tenant never has to find the full amount upfront.

This can free up cash for other setup costs when you first arrive, such as furniture or a moving company, which is often the main reason tenants choose it over a bank account. The trade-off is that the premiums are not refundable and, over a long tenancy, their total cost can exceed what a cash deposit would have cost you. Not every landlord accepts this type of guarantee, so check before you commit to it, and compare the terms of different providers rather than assuming they are interchangeable.

Getting your deposit back when you move out

The deposit is released once the landlord confirms in writing to the bank, after the move-out inspection, that they have no claim against you. Where the landlord does raise a claim, for damage beyond normal wear and tear, unpaid rent or charges, the process slows down, since the bank will not release funds without either the landlord's agreement or a court decision.

This is where most friction happens: a landlord who disputes the state of the property at the exit inspection can delay release of the deposit for months, and a tenant who leaves without a documented, signed inspection report has little to point to if a disagreement arises later. Article 257e also sets a backstop: if the landlord has not started legal proceedings within one year of the end of the tenancy, the bank must release the deposit to the tenant regardless.

What a landlord can and cannot deduct

A landlord may only withhold part or all of the deposit for a documented reason: physical damage to the property beyond ordinary wear and tear, unpaid rent, outstanding charges, or contractually agreed cleaning that was not carried out. Fading paint, worn flooring or other changes that result from normal use over the years cannot be charged to the tenant, since Swiss tenancy practice treats reasonable ageing of fittings as the landlord's responsibility, not the tenant's.

If you disagree with a deduction, every canton has a conciliation authority for tenancy disputes that tenants and landlords can approach before going to court. This route is designed to be accessible without a lawyer and is the normal first step in a deposit dispute; if conciliation does not resolve the matter, the case can proceed to the ordinary tenancy court.

Choosing between a bank account and deposit insurance

The right choice depends mainly on your cash position and how long you expect to stay. If you have the funds available and expect to stay for several years, a blocked bank account means you keep full ownership of the capital and recover the whole amount, plus any accrued interest, once the tenancy ends cleanly.

If preserving liquidity in the first months after your move matters more, for example because you are also covering removal costs, a first deposit on a new home purchase, or setting up a household from scratch, a guarantee-based product avoids locking up several months' rent at once. There is no single right answer: weigh the ongoing premium cost against how long you realistically expect to stay before deciding, and factor this choice into your broader relocation budget.
