Priminfo (Federal Housing Portal)

Priminfo is not a listings platform but the government portal that explains the legal framework every Swiss rental sits within. For someone arriving from a country with different tenancy law, understanding the Swiss system upfront avoids costly mistakes: the deposit is capped at three months’ net rent, it must be lodged in a blocked bank account in the tenant’s name (not the landlord’s), and the standard notice period is three months to a fixed quarter date.

The site also covers the tenant’s right to contest rent increases and the rules around the initial rental price, which matters in cantons that limit new tenancy rents in tight markets. Reading the basics before signing a lease in Switzerland takes an hour and prevents several common problems.
