Federal Act
on the Amendment of the Swiss Civil Code
(Part Five: The Code of Obligations)

¹ The ten­ant or less­ee must use the ob­ject with all due care.

² Where the lease relates to im­mov­able prop­erty, the ten­ant must show due con­sid­er­a­tion for oth­ers who share the build­ing and for neigh­bours.

³ If, des­pite writ­ten warn­ing from the land­lord or lessor, the ten­ant or less­ee con­tin­ues to act in breach of his duty of care and con­sid­er­a­tion such that con­tinu­ation of the lease be­comes un­con­scion­able for the land­lord or lessor or oth­er per­sons shar­ing the build­ing, the land­lord or lessor may ter­min­ate the con­tract with im­me­di­ate ef­fect or, for leases of res­id­en­tial and com­mer­cial premises, sub­ject to at least 30 days’ no­tice end­ing on the last day of a cal­en­dar month.

⁴ However, leases of res­id­en­tial and com­mer­cial premises may be ter­min­ated with im­me­di­ate ef­fect if the ten­ant in­ten­tion­ally causes ser­i­ous dam­age to the prop­erty.
