The Rental Deposit Account Explained
How the Swiss rental deposit works in Zurich: the three-month cap, the blocked Sperrkonto in your name, deposit guarantee options, and getting it back.
Key Takeaways
- The deposit is capped at three months rent including Nebenkosten and held in a blocked account in your name.
- A deposit guarantee can replace cash for about CHF 150 to 400 a year if liquidity is tight.
- The landlord has 30 days after move-out to object, and cannot deduct for normal wear and tear.
Handing over a large deposit is one of the bigger upfront costs of a Zurich move, often three months of rent at once. The reassuring part is that Swiss law treats the deposit as firmly the tenant's money, held safely and returnable. Understanding how the blocked account works, and your rights around it, ensures you get every franc back when you eventually leave.
The legal cap
The Mietkaution (rental deposit) is capped by law at three months' rent including Nebenkosten, under Article 257e of the Code of Obligations. Any clause demanding more is void. On a CHF 2,800 flat, that means a maximum of around CHF 8,400. Always check the contract figure against this ceiling before you pay.
The blocked account (Sperrkonto)
Your deposit must go into a Sperrkonto (blocked deposit account) at a bank, opened in your name, not the landlord's. The landlord cannot touch it without your written consent or a court order, and any interest it earns belongs to you. Never transfer a deposit to a landlord's private account; insist on a proper blocked account.
The guarantee alternative
If locking away three months' rent strains your finances, a Mietkautionsversicherung (deposit guarantee) lets a provider guarantee the deposit for an annual fee of roughly CHF 150 to 400. Landlords must accept a reputable guarantee instead of cash, though some still prefer a Sperrkonto, so confirm before relying on it. It frees up cash but costs a yearly premium.
Getting it back
When you leave, both you and the landlord must sign to release the funds. The landlord has 30 days after you move out to raise any written objections, such as damage beyond normal wear or unpaid costs. With a clean handover and bills settled, the deposit is typically released within one to three months of departure.
What can and cannot be deducted
A landlord may only deduct for genuine damage beyond normal wear and tear, unpaid rent or outstanding ancillary costs, with itemised justification. Normal wear and tear, and age-related deterioration, are the landlord's cost, not yours. Knowing this prevents you from being charged for ordinary use of the flat over your tenancy.
If there is a dispute
If the landlord withholds your deposit unfairly, you can demand release and, if needed, take the matter to the free Schlichtungsbehörde (conciliation authority). A documented handover protocol and photos are your best evidence. The system is built to protect tenants, so a well-documented claim usually prevails.
The deposit may feel like a lot of money disappearing, but in Switzerland it remains yours throughout, protected in a blocked account in your name and returnable in full barring real damage. Check the amount is legal, insist on a proper Sperrkonto, document the flat at both ends, and your deposit will come back as it should.
