In Switzerland, rent increases are only permitted under specific conditions and must use the official cantonal form.

## Permitted reasons for a rent increase


- Rise in the reference mortgage interest rate
- Increased maintenance and operating costs
- Value-adding investments
- General cost increases (CPI)


> **Reference interest rate**
>
> Set quarterly by the Federal Housing Office (FHO). A rise of 0.25 percentage points allows a 3% rent increase.


## Official form is mandatory


Any rent increase must use the official cantonal form. Notification by email is not legally valid.
