The security deposit: protection of the tenant's money

The security deposit is a form of guarantee for the landlord. In Switzerland, the maximum is three months of monthly rent, a federal and uniform figure. It should not be confused with the additional (rare) deposit, which would have different limits. The deposit must remain in a special restricted account, in the tenant's name, and not available to the landlord for his personal use during the term of the contract.

Upon return of the property, the landlord may deduct only specific amounts from the deposit: damages beyond ordinary wear and tear, unpaid fees, and documented extraordinary cleaning expenses. The deposit must be returned within 30 days of the end of the contract. If the landlord does not comply with this deadline without documented justification, the tenant may appeal to the conciliation authority.

Step 1: Document collection (days 1-15). Gather objective evidence: local real estate ads for similar properties, photos of the property's condition, technical characteristics (size, number of rooms, age, services). Consult public real estate databases for comparable properties in the area.

Step 2: Preparing the appeal (days 16-25). Draft a written appeal addressed to the Zurich canton's conciliation authority in matters of rental. Include: contract identification data (addresses, names, date of signature), contested rent, reasons for contestation (market references, property conditions), and proposed fair amounts.

Step 3: Official submission (day 30). Send the appeal by registered mail with return receipt to the cantonal conciliation office (address available on the Zurich canton's official website). Keep the receipt: it serves as proof of timely submission.

Step 4: Conciliatory hearing. Wait for the official invitation to a conciliatory hearing. Attend in person or be represented. Bring a copy of the original documentation.

Step 5: Decision and appeal. The authority will issue a decision. If dissatisfied, you have the right to appeal to the civil court within the time limits set by the cantonal law.
