What is the maximum rental deposit a Swiss landlord can legally demand?

Under Art. 257e Abs. 2 of the Swiss Code of Obligations (OR / SR 220), the security deposit for residential premises may not exceed three months' gross rent (net rent plus advance heating and operating costs). Any contractual clause demanding more than 3 months is null and void (nichtig).

How must a rental deposit be held in Switzerland?

Under Art. 257e Abs. 1 OR, the landlord must deposit the funds in a blocked savings account (Mietkautionskonto) at a bank in the tenant's sole name. It is illegal to deposit rental guarantee funds in the landlord's personal or foreign account.

When must a Swiss rental deposit be refunded after moving out?

If both parties sign an undisputed joint handover protocol (Wohnungsabnahmeprotokoll), the bank releases the funds within days. If disputed, under Art. 257e Abs. 3 OR, if exactly 1 year passes from the lease termination date without legal debt enforcement (Betreibung) or court action initiated by the landlord, the bank must release 100% of the funds to the tenant upon their sole written request.

Is rental guarantee insurance (Mietkautionsversicherung) legal in Switzerland?

Yes, rental guarantee insurance is legally recognized as an alternative to cash deposits, provided the landlord agrees to accept a surety guarantee certificate. However, annual insurance premiums are non-refundable.

PRE-SIGNING LEASE AGREEMENT DUE DILIGENCE

5-Point Swiss Tenancy Contract Checklist

Essential legal verifications before signing any Swiss residential lease agreement.

1. 3-Month Deposit Ceiling (Art. 257e Abs. 2 OR)

Verify that the security deposit does not exceed 3 months of gross rent (Net rent + Nebenkosten advance).

2. Blocked Account in Tenant's Sole Name (Art. 257e Abs. 1 OR)

The deposit must be held in a blocked savings account in your name at a Swiss bank. Never wire deposit money to a landlord's personal or foreign account.

3. Ancillary Utilities (Akonto vs. Pauschal)

Verify whether heating and operating costs are billed as an advance payment (Akonto with annual reconciliation) or a flat fee (Pauschal).

4. Mortgage Reference Interest Rate (Referenzzinssatz)

Check the mortgage reference rate basis stated in the lease (federal benchmark: 1.75%). Rate decreases entitle tenants to rent reductions.

5. Notice Period & Local Moving Dates (Art. 266c OR)

Standard residential notice is 3 months to the end of a month. Check whether your canton specifies official local moving dates (Ortsübliche Kündigungstermine).
