Rental Deposits in Switzerland: Rules, Limits, and How to Get Yours Back

The rental deposit (Mietkaution) is one of the first significant financial transactions when renting in Switzerland — and one of the most misunderstood. Swiss law places strict limits on deposits and gives tenants specific rights around how the money is held and returned.

Whether you are just moving in, about to move out, or are trying to recover a deposit that is being withheld, this guide covers everything you need to know.

The Legal Maximum: 3 Months' Rent

Swiss law (OR Art. 257e) is explicit: a landlord may not demand a deposit of more than three months' net rent (Nettomiete).

This applies to:

• Unfurnished residential apartments
• Furnished apartments
• Shared flats (each tenant's share of the deposit cannot exceed 3 months)

Example: If your net rent is CHF 1,800/month, the maximum deposit is CHF 5,400.

Any landlord who demands more than three months' net rent is acting illegally. If you have already paid an excessive deposit, you can demand the excess back.

Note: the three-month limit applies to net rent, not Bruttomiete (total including Nebenkosten). If your rent is CHF 1,800 net + CHF 200 Nebenkosten, the deposit maximum is still based on CHF 1,800.

Where Must the Deposit Be Held?

This is where many tenants are unaware of their rights. Swiss law requires that the deposit be held in a blocked bank account (Sperrkonto) in the tenant's name, not the landlord's.

The rules:

• The account must be opened at a Swiss bank in your name as tenant
• The account is blocked — neither you nor the landlord can withdraw funds without the other's agreement (or a court order)
• Interest earned on the account belongs to you, not the landlord
• The landlord never owns or controls the money — it is yours, held as security

Red flags:

• A landlord asking you to pay the deposit directly into their personal or business account — this is illegal
• A landlord claiming to hold the deposit "in trust" without a formal Sperrkonto — not acceptable
• A landlord who cannot produce evidence of where the deposit is held

If your landlord insists on non-standard deposit arrangements, consult the Mieterverband before proceeding.

Types of Deposit Arrangements

Standard Sperrkonto

You go to a Swiss bank, open a blocked savings account in your name, deposit the funds, and provide the landlord with confirmation. The landlord cannot access the money without a court order or your written consent.

This is the most common arrangement and the most protective for tenants.

Bank Guarantee (Mietkautionsversicherung)

An alternative to paying a deposit upfront: a bank or specialist insurance company (e.g., SwissCaution, FirstCaution) provides a guarantee to the landlord on your behalf. You pay an annual premium (typically 3–5% of the deposit amount) instead of tying up capital.

Pros: No large upfront cash outlay Cons: Premium is not refundable; you pay year after year

This is particularly useful for tenants who cannot immediately access CHF 4,000–6,000 in cash.

How Long Can a Landlord Hold Your Deposit After You Leave?

This is where disputes most frequently arise. After you vacate the apartment:

1. The landlord has 30 days to either release the deposit in full or raise documented written objections
2. If the landlord raises objections, the deposit remains blocked until the dispute is resolved — either by agreement or by a court
3. If no objections are raised within 30 days, you are entitled to the full deposit plus accumulated interest

How to release a deposit:

• Both you and the landlord sign a release form at the bank (or submit one jointly)
• Alternatively, the landlord signs a release form acknowledging no outstanding claims
• If the landlord refuses, the Schlichtungsbehörde can order the release

What Can a Landlord Deduct from the Deposit?

The landlord may only deduct from the deposit for:

• Unpaid rent — any months of rent left unpaid
• Damage beyond normal wear and tear — broken fixtures, holes in walls, significant stains, damage to appliances
• Unpaid Nebenkosten — if a reconciliation is outstanding
• Costs of cleaning — if the apartment was returned in unacceptable condition

The landlord cannot deduct for:

• Normal wear and tear (Altersverschleiss) — the gradual fading of paint, worn carpets, small marks from normal use
• Cosmetic improvements — repainting in a different colour counts as improvement, not repair
• Damage that existed before you moved in — this is why the move-in protocol is critical

The Wear-and-Tear Principle

Swiss courts apply a clear principle: apartments deteriorate normally over time. A landlord cannot expect to receive the apartment back in brand-new condition after 5 or 10 years of occupancy.

Typical lifespans used in Swiss courts:

• Interior paint: 8–12 years
• Wall-to-wall carpeting: 8–10 years
• Parquet flooring: 15–25 years
• Kitchen appliances: 10–15 years

If the paint is 7 years old when you leave, you cannot be charged for full repainting — at most a fraction proportional to remaining expected lifespan.

Your Move-Out Protocol Rights

The handover on departure is as important as the one on arrival:

1. Schedule the handover inspection with the landlord — both parties should attend
2. Walk through every room together, noting any damage or issues in writing
3. Both parties sign the handover protocol
4. Request a copy immediately — do not leave without your signed copy
5. Any disputed items should be noted as disputed, not agreed

If the landlord refuses to complete a handover protocol, document the condition of the apartment yourself with dated photos and video, and send copies by registered post immediately.

If Your Landlord Refuses to Return Your Deposit

If 30 days have passed after your move-out and the landlord has not released the deposit or raised formal objections:

1. Write to the landlord formally demanding release within 10 days (by registered post)
2. If no response, file a claim with the Schlichtungsbehörde — free of charge, quick process
3. If the Schlichtungsbehörde cannot resolve it, the case goes to civil court

In practice, most disputes are resolved at the Schlichtungsbehörde level. Courts are rarely needed.

Deposit for Cooperative Housing

Genossenschaftswohnungen involve two separate financial contributions, which are often confused:

• Mietkaution — the standard security deposit (same rules as above, max 3 months' net rent)
• Anteilschein (membership share) — a separate equity stake in the cooperative, typically CHF 500–5,000

The Anteilschein is not a deposit — it is an ownership share. It is returned when you leave the cooperative, not when the apartment is cleaned. These are separate transactions with separate legal rules.

Frequently Asked Questions

Can a landlord ask for more than 3 months' deposit?

No. Swiss law (OR Art. 257e) caps the deposit at three months' net rent. If a landlord demands more, you can refuse and/or report it to the Schlichtungsbehörde. Any amount paid above the legal maximum can be reclaimed.

My landlord is holding my deposit in their own account. Is this legal?

No. The deposit must be held in a blocked bank account (Sperrkonto) in your name. A landlord holding it in their own account is violating Swiss law. You can demand that it be moved to a proper Sperrkonto immediately.

How long does it take to get the deposit back after moving out?

If there are no disputes, the deposit should be released within 30 days. In practice, if both parties agree on condition, banks can release funds within a few days once both parties sign the release form.

Can the landlord keep the deposit for cleaning costs?

Only if the apartment was returned in clearly unacceptable condition — not cleaned, not swept, heavily soiled. Normal cleaning that a tenant has carried out to a reasonable standard cannot be charged. The key question is whether the apartment was returned in the condition required by the contract.

What interest does the deposit earn and who gets it?

The interest earned on the Sperrkonto belongs to the tenant. Interest rates are low (Swiss savings rates are currently near 0%), so the practical amount is modest, but the principle is that the money remains yours throughout the tenancy.
