Notice Periods and Protection Against Termination in Rental Contracts

Imagine this: You want to move out of your apartment, or you're afraid the landlord might suddenly terminate the lease. Many tenants sign contracts where the notice period is too short or where protection against termination is weakened. According to the 2026 Tenant Barometer, termination disputes are among the top complaints.

Good news: You can spot the most important pitfalls just by reading the contract. On welfarecalc.ch you can view all 30 risk points regarding termination and deadlines completely free – without uploading a contract. We explain everything here as simply as if your 5-year-old self were listening.

Let's go!

1. Notice period too short (less than 3 months)

📄 Original clause in the contract (common):
"Either party may terminate the lease with one month's notice as of the end of any calendar month."

⚠️ Why is this dangerous? For residential premises, the statutory minimum notice period under Art. 266k CO is 3 months as of the end of a month. Shorter periods place the tenant at a significant disadvantage and are generally invalid.

🧒 Explanation in simple terms: Imagine you had only 30 days to pack up your entire room and find a new place to live – that's almost impossible. The law gives you at least 3 months to calmly find a solution.

✅ What you should do: Always insist on at least 3 months as of the end of a month. Reject or have shorter notice periods removed.

2. Automatic renewal with excessive notice period

📄 Original clause:
"The lease shall automatically renew for an additional year unless notice is given at least 6 months in advance."

⚠️ Why is this dangerous? An excessively long notice period for the tenant (longer than 3 months) or an automatic renewal without a genuine choice is often considered abusive.

🧒 Simple terms: That would be like signing a contract for the playground and then not being able to leave, even if you no longer want to play.

✅ Correct: Normal renewal for 1 year with a 3-month period for ordinary termination.

3. Termination only on fixed dates (e.g., only March 31 or September 30)

📄 Original clause:
"Termination is only possible as of March 31 or September 30."

⚠️ Why is this dangerous? The statutory rule is termination as of the end of a month with 3 months' notice. Restrictions to specific quarterly dates are only permissible if they apply equally to both parties and are not disadvantageous.

🧒 Simple terms: You shouldn't only be allowed to say "I want to stop" on two specific days of the year. That would be unfair.

4. Probationary period with shortened notice period

📄 Original clause:
"During the first 6 months, the lease may be terminated with 14 days' notice."

⚠️ Why is this dangerous? A probationary period with a shortened notice period does not exist for residential leases under Swiss law. The 3-month period applies from day one.

🧒 Simple terms: There is no "probation period" during which you can be thrown out faster. The rules apply from the very first day.

5. Circumventing protection against termination (e.g., owner-use clause without justification)

📄 Original clause:
"The landlord may terminate the lease at any time for owner-occupancy reasons."

⚠️ Why is this dangerous? Terminations due to owner-occupancy or sale are only permissible under strict conditions and must be justified. Abusive terminations can be challenged (Art. 271 CO – protection against termination).

🧒 Simple terms: The landlord can't just kick you out because they suddenly want to move in themselves or sell at a higher price. There are strict rules to protect tenants.

6. Retaliatory termination following defect reports or complaints

📄 Original clause:
"In the event of repeated complaints or defect reports, the landlord reserves the right to terminate the lease."

⚠️ Why is this dangerous? A termination in response to justified defect reports or complaints is abusive and can be challenged before the conciliation authority.

🧒 Simple terms: If you say "the heating is broken," the landlord can't reply "then move out." That's forbidden.
