Subletting a room or apartment in Switzerland: legal guide

Subletting is legal and common in Switzerland. Requires authorization from the owner and, preferably, a written contract to avoid misunderstandings.

Subletting is a widespread practice in Switzerland, allowing a main tenant to rent a room or the entire home to a third party. However, to be safe and legal, clear rules must be followed.

1. The Sublease Contract

Although verbal contracts can be valid in Switzerland, a written contract is essential to avoid disputes. Must include:

  • Identity of the main tenant and subtenant.
  • Object: Is it a room or the entire floor? Specify common areas.
  • Duration: Start and end date (if determined).
  • Price and expenses: Specify if it includes electricity, internet, etc.
  • Notice: Time necessary to terminate the contract.

2. The Deposit (Guarantee)

It is common to request between 1 and 2 months of deposit. It is important to remember that:

  • The deposit cannot be used as payment for the last month.
  • Must be returned in full if there are no damages or outstanding debts.
  • It is recommended to take a small inventory with photos when entering to avoid arguments when leaving.

3. Owner Authorization

This is the most critical point: the sublet must be authorized by the owner of the property. Although it is not usually opposed if there is no abuse (such as subletting for a much higher price than the original), doing so secretly may be grounds for termination of the main contract.

Tip: Always leave everything "black on white". In Switzerland, ambiguity often works against those who do not have written evidence.
