How do I terminate my tenancy in Switzerland?
It depends who's terminating — but the notice periods and form rules are clear. For a flat, the statutory notice period is at least three months (Art. 266c OR), and six months for business premises. Notice is given to the locally customary dates unless otherwise agreed. It must be in writing; the landlord must use the official form, otherwise the termination is void (Art. 266l/266o). For a family home, notice must go separately to each spouse. Against an abusive termination you can act within 30 days at the conciliation authority; an extension is also possible. In short: yes, with notice, form and to the right date.
📋 The rules
- Flat: min 3 months notice (business 6)
- To the locally customary dates

- Landlord: official form, otherwise void
- Challenge within 30 days at the conciliation authority

⚠️ Penalties & fines
A termination by the landlord without the official form, or notice on a family home to only one spouse, is void and has no effect. An abusive termination (contrary to good faith, e.g. in retaliation for a justified claim) is challengeable. Beware a myth: "the landlord can terminate any time, informally" is false — they need the official form and must respect the notice period and date. Tip: always send notice by registered post and on time, and watch the 30-day window for a challenge.

❓ Frequently asked
How long is the notice period?
For a flat the statutory notice period is at least three months, and for business premises six months. For furnished rooms or single parking spaces it's two weeks to month-end. The period may be lengthened by contract, but it may not be shortened below the statutory minimum.
To which date must I give notice?
You give notice to the locally customary dates, unless the contract says otherwise. End of March, June and September are common, often not December, but this varies locally. Check your contract and the customary moving dates of your commune before serving notice.
Must notice be in writing?
Yes, for both sides notice must be in writing. The landlord must additionally use the official cantonal form, otherwise their termination is void. As a tenant a written notice is enough, ideally by registered post, so that you can prove when it was sent.
What applies to a family home?
For a family home the landlord must give notice to both spouses separately, each on their own form. If that isn't done, the termination is void. A tenant giving notice should also note that both spouses need to be involved in ending the tenancy of a family home.
Can I challenge a termination?
Yes. A termination contrary to good faith can be challenged within 30 days at the conciliation authority. An extension of the tenancy is also possible, up to four years for flats. Be sure to keep to the short 30-day window, as it's strict and easily missed.
