Subletting Your Flat in Switzerland: Legal Rights & Landlord Consent (Art. 262 OR)
Whether traveling abroad for a sabbatical or temporarily relocating for a job assignment, Swiss tenants possess a statutory right to sublet their apartment (Untermiete) under Article 262 of the Swiss Code of Obligations. However, failure to comply with landlord consent rules can lead to immediate lease termination.
1. The Statutory Right to Sublet (Art. 262 Abs. 1 OR)
Under Swiss law, subletting is considered an inherent right of the tenant. While you must obtain the landlord's consent (Zustimmung des Vermieters) prior to the subtenant moving in, the landlord cannot arbitrarily deny permission.
Under Article 262 paragraph 2 of the Code of Obligations, the landlord may only refuse consent in three narrowly defined situations: (1) if the tenant refuses to disclose the sublease terms and subtenant identity; (2) if the terms of the sublease are abusive (missbräuchlich) compared to the main lease; or (3) if the subletting causes significant disadvantages to the landlord (e.g., overcrowding or disruptive commercial use).
A tenant may never profit commercially from subletting an unfurnished flat. For furnished sublets, a modest surcharge of 10% to 20% is legally permitted to cover furniture wear, broadband internet, and electricity. Any excessive surcharge (such as commercial Airbnb arbitrage) constitutes an unlawful lease violation.
2. Step-by-Step Sublease Application Protocol
To protect yourself legally, always submit a formal written request to your property manager (Verwaltung) at least 3 to 4 weeks before the sublease begins.
Include a copy of the draft sublease contract (Untermietvertrag), the subtenant's full names and contact information, the exact rental duration, the breakdown of rent and utility surcharges, and confirmation of your intention to return to the apartment at the conclusion of the sublease period.

Frequently Asked Questions
Can my Swiss landlord completely ban subletting in the contract?
No. General clauses in standard rental contracts completely banning subletting are invalid under Art. 262 OR. The landlord must evaluate each sublease request individually based on the statutory grounds in federal law.
How much extra rent can I charge for a furnished sublet?
The Swiss Federal Supreme Court and tenancy authorities benchmark a fair surcharge for furniture, appliances, and high-speed internet at approximately 10% to 20% over the underlying gross rent.
Can I sublet my apartment indefinitely?
No. The main tenant must demonstrate a credible intention to re-occupy the apartment in the future (Rückkehrabsicht). If you relocate permanently without intention to return, the landlord can demand that you terminate the main lease.
