Sublease Agreement under Art. 262 CO: Legal Requirements in Switzerland

Under Swiss tenancy law, residential subletting is legally protected by Article 262 of the Swiss Code of Obligations (CO): tenants have a statutory right to sublet their home, provided they obtain the prior consent of the landlord. Designed to assist international expats, sabbatical travelers, and flatmates, this rule ensures tenants do not have to give up their lease during temporary absences. Crucially, a landlord cannot arbitrarily withhold permission; refusal is legally permissible only under the three strict statutory conditions set out in Art. 262 para. 2 CO.

1. The Three Statutory Grounds for Landlord Refusal (Art. 262 para. 2 CO)

In Switzerland, landlord consent cannot be withheld at will. The Swiss Code of Obligations strictly limits the right of refusal to three specific scenarios:

a) Refusal to Disclose the Terms of the Sublease (Art. 262 para. 2 lit. a CO)

As the main tenant, you must submit a formal written notification disclosing:

• Full legal name, current address, and passport/ID copy of the subtenant
• Which specific rooms or areas will be occupied
• The start and end dates (or notice periods for open-ended subleases)
• Exact sublease rent, shared utility costs, and furniture charges

If you fail to provide this documentation or refuse to reveal the contract, the landlord has the legal right to decline. Review our guide on the Swiss sublease agreement fillable PDF template to see standard management disclosure requirements.

b) Abusive or Exploitative Sublease Terms (Art. 262 para. 2 lit. b CO)

Subletting must not be used as a profit-making enterprise. The rent charged to the subtenant must correspond directly to the proportional main rent. For fully furnished apartments with high-speed internet and utilities, Swiss tenancy courts permit a reasonable surcharge of 10% to 20% to account for furniture wear and overhead. Any surcharge above 20% is considered legally abusive and grounds for immediate refusal.

c) Significant Disadvantages to the Landlord (Art. 262 para. 2 lit. c CO)

A landlord can refuse consent if the sublet creates palpable harm or disturbance. Typical legal grounds include severe overcrowding (e.g. four individuals in a one-bedroom flat), utilizing a residential flat for noisy commercial activities, or operating a commercial short-term holiday let (like Airbnb) that results in frequent stranger traffic and neighbor complaints.

3. Primary Tenant Liability and Essential Cross-Document Protection

Pursuant to Art. 262 para. 3 CO, the primary tenant remains strictly liable to the landlord for ensuring that the subtenant treats the property with care. If rent is delayed or damage occurs, the main tenant is on the hook. To safeguard your legal and financial interests, consider these essential documents:

• Protecting against rent arrears: If a subtenant defaults on monthly rent, securing a written acknowledgment of debt enables swift provisional debt enforcement under Art. 82 of the Swiss Debt Enforcement and Bankruptcy Act (DEBA/SchKG).
• Head lease termination: The sublease is legally tied to the master tenancy. If your own lease ends via a formal termination of the rental agreement, the subtenant's right of occupancy expires on the exact same date.
• Representation while living abroad: During an expatriate assignment or sabbatical, executing a Swiss general power of attorney empowers a trusted contact in Switzerland to liaise with building management and handle urgent maintenance.
• Comprehensive personal planning: Major life transitions, relocations, or asset acquisitions are an ideal moment to examine how to make a legally valid will in Switzerland to protect your heirs and global estate.

4. Step-by-Step Guide to a Legally Compliant Sublease

1. Calculate the sublease rent: Determine the exact proportional share of the master rent and cap any furniture or utility surcharges at 10% to 20% maximum.
2. Draft the agreement: Use the verified online generator on onlinedokument.ch to include all statutory clauses, notice terms, and deposit provisions.
3. Submit the consent request: Send the draft agreement along with the subtenant's personal details and ID copy to your property management.
4. Open a rental deposit account: Set up a statutory blocked security deposit account under Art. 257e CO in the subtenant's name prior to key handover.
5. Complete a check-in protocol: Thoroughly document the condition of the rooms and draw up a detailed furniture inventory on the move-in date.
