What is the maximum period under Swiss tenancy law for an extension of the tenancy if the contract is terminated due to personal use?

Maximum extension period

According to Art. 272b OR, a rental agreement for residential spaces can be extended for a maximum of four years. For commercial premises, the maximum period is six years. Within this framework, one or two extensions may be granted. Even with owner's own use, this maximum persists, but “urgent” owner's own use by the landlord usually reduces the period granted significantly in practice, as the owner's interest in using it is weighted higher than the tenant's social hardship.

The legal guidelines: 4 years as an absolute limit

The Swiss Code of Obligations (OR) is clearly structured. The extension serves to alleviate the consequences of the termination by saving time.

Living spaces vs. commercial spaces

• living spaces: This is finally over after 48 months (4 years) at the latest. An extension beyond this period is legally impossible, even if the tenant has not found a new apartment by then.
• commercial premises: Since the search for commercial space is often more complex (specific expansions, customer loyalty to the location), the law allows up to 6 years here.

The big balance: Tenant hardship vs. landlord demand

The conciliation authority does not decide at random, but applies a strict balance of interests. In 2026, the hurdles faced by tenant due to the extreme housing shortage in cities such as Basel or Lausanne are high, but the authorities are sensitized.

Factors for a long extension (tenant side):

• Long period of residence: Anyone who has lived in the same apartment in Zurich District 6 for 30 years enjoys more protection than someone who only moved in a year ago.
• Social roots: Children in the local school, care obligations nearby or the tenant's old age.
• Local market situation: The current vacancy rate. The more difficult the search, the more the extension will trend towards the maximum.

Factors for a short extension (landlord side):

• urgency: Does the landlord have to leave his current apartment? Does he have a valid reason (e.g. family growth or return from abroad)?
• Close relatives: owner's own use apply to children or parents, they are weighted higher than for a godchild.

Special case: “urgent” owner's own use

The term “urgency” is a precise legal instrument in 2026. If the landlord can prove that his owner's own use are urgent, that changes the rules of the game.

What does urgent mean?

There is urgency when the landlord cannot be expected to continue renting out the apartment for economic or personal reasons.

• Consequence for the lockdown period: Urgent owner's own use allows the landlord to even break an ongoing three-year blocking period.
• Consequence for extension: Although the maximum of 4 years remains theoretically valid, the conciliation authority will make the extension significantly shorter (e.g. only 6 to 12 months) in order to meet the urgent needs of the owner.

The process: One-time or two-time extension?

In Switzerland, an initial extension is usually granted first.

• First extension: Typically for 1 to 2 years. The tenant must demonstrably make search efforts during this period.
• Second extension: If the search was unsuccessful, a second extension can be requested shortly before the first deadline expires — until the 4-year maximum is reached.
• Definitive extension: Sometimes the parties agree on a one-time, definitive extension (e.g. fixed 2 years), after which the tenant must move out without any ifs or buts. This gives both sides planning security.
