Swiss tenancy law (Mietrecht / droit du bail) is heavily regulated to protect tenants. The relevant provisions are found in OR Art. 253–273c, supplemented by the VMWG ordinance. Whether you're renting an apartment in Zürich, Geneva, or a smaller town, understanding your rights is essential before signing.
One of the most critical areas is the rental deposit (Mietzinskaution / garantie de loyer). Under OR Art. 257e, the deposit may not exceed three months' rent, and the landlord must deposit it in a separate escrow account (Sperrkonto) at a bank in the tenant's name. Any clause requiring a higher deposit or allowing the landlord to hold the deposit privately is illegal.
Tenants can challenge the initial rent as abusive within 30 days of moving in (OR Art. 270). Rent increases are only valid if they follow the official procedure using the approved form and are justified by reference rate changes, cost increases, or capital improvements. Termination of tenancy is protected: the landlord must use an approved form, and tenants can request an extension of up to 4 years for residential leases if termination would cause hardship.

Common Red Flags in Rental Contracts
- Deposit exceeding 3 months' rent — illegal under OR Art. 257e
- No escrow account (Sperrkonto) for the deposit — the landlord must hold it in a separate bank account in the tenant's name
- Unfair renovation or restoration clauses requiring the tenant to restore the property to "as new" condition — exceeds normal wear and tear obligations
- Termination provisions that bypass the required official form or shorten notice periods below the legal minimum (OR Art. 266a ff.)

Frequently Asked Questions
Can my landlord ask for more than 3 months' deposit?
No. Under OR Art. 257e, the rental deposit may not exceed three months' rent for residential leases. The deposit must be held in a bank escrow account in the tenant's name. Any clause requiring a higher deposit is void.
Can I challenge my initial rent?
Yes. Under OR Art. 270, you can challenge the initial rent within 30 days of moving in if you believe it is abusive. This is especially relevant in areas with housing shortages. The conciliation authority or rental tribunal will assess whether the rent is excessive.
What happens when I move out — do I have to repaint?
Normal wear and tear (Abnützung) is the landlord's responsibility. You only need to repair damage beyond normal use. Clauses requiring tenants to repaint or renovate at their own cost upon move-out are often contested and may be void if they exceed what is reasonable.
