Apartment Swap in Switzerland: Process, Legal Rules and Tips for the Swap Apartment

An apartment swap is an arrangement in which two tenant households hand their apartments over to each other and each moves into the other’s home. The landlords of both apartments have to agree, and new rental agreements are concluded for both apartments.

Which variants of an apartment swap are there?

An apartment swap can take place as a direct swap between two parties, as a ring swap involving three or more parties, or as a time-limited holiday swap (home exchange). Each variant involves a different coordination effort and different contractual requirements. An apartment swap can be permanent or arranged for a defined period.

The direct swap is the simplest form: two parties exchange their apartments directly, and each side only needs the consent of its own landlord. In a ring swap, three or more households coordinate their move at the same time, which increases the coordination effort considerably because all contracting parties and landlords have to give the green light simultaneously. The holiday swap (home exchange) is a temporary exchange without a permanent change of contract, although the subletting rules under Art. 262 CO still have to be observed.

Is an apartment swap legal in Switzerland?

An apartment swap is permitted in Switzerland, but there is no statutory entitlement to one. The landlords of both apartments have to agree voluntarily, and they may refuse a request without giving reasons. If both apartments belong to the same owner or property management, a single consent is enough. That is the easiest starting position, because the landlord keeps both apartments occupied and risks no vacancies.

The Swiss Code of Obligations does provide for a rental agreement to be transferred to a third party, which may only be refused for good cause. However, that rule in Art. 263 CO expressly applies to business premises only. For residential apartments there is no equivalent provision: a swap is a matter of freedom of contract, and therefore of negotiation.

In practice, an apartment swap therefore does not run through a contract transfer but through two separate transactions per apartment: the outgoing tenant gives notice or ends the agreement by mutual consent, and the landlord concludes a new rental agreement with the incoming party. The landlord can set the rent afresh accordingly, and there is no legal guarantee that the previous rent will simply carry over.

If you are unsure how much room your own situation leaves you, the Swiss Tenants’ Association (Mieterinnen- und Mieterverband, MV) can advise you.

How does an apartment swap work step by step?

An apartment swap follows a clear sequence of eight steps, and asking your landlord early is the most critical one. Anyone who wants to swap their rented apartment has to speak to their landlord first, before further steps such as viewings or giving notice are set in motion. The statutory notice period of three months to a locally customary date under Art. 266c CO determines the schedule.

Step 1: Create a swap listing

• When: At the start of the process, before you actively look for swap partners.
• Action: Create a meaningful swap listing with photos, number of rooms, size in m², location, rent and a clear description of the apartment you are looking for.
• Tip: The more specific your wish list, the better the enquiries you receive will fit. Name the neighbourhood you want and the number of rooms explicitly.

Step 2: Find a swap partner

• When: Immediately after creating the listing; this step can take weeks to months.
• Action: Publish your swap listing on specialised swap platforms and check incoming enquiries carefully for fit.
• Tip: Approach neighbourhood groups and social networks as well, to widen your search radius.

Step 3: Contact the landlords on both sides

• When: As soon as a potentially suitable swap partner has been found, before the viewing.
• Action: Contact your landlord in writing and ask for consent to the swap in principle. Your swap partner does the same on their side.
• Tip: Asking early prevents a rejection after you have already invested in viewings and emotional effort. Always get the consent in writing, even though the law prescribes no particular form for it.

Step 4: Organise mutual viewings

• When: After a positive signal from both landlords.
• Action: Organise mutual apartment viewings so that both parties can assess the new home realistically.
• Tip: Use these tips for the flat viewing so you do not overlook anything essential.

Step 5: Submit notice in writing

• When: After both sides have reached a definitive agreement.
• Action: Submit your notice in writing and on time. The statutory period is three months to a locally customary date under Art. 266c CO.
• Tip: Check your rental agreement for any shorter contractual notice periods or differing dates.

Step 6: Conclude the new rental agreements

• When: After notice has been given, as soon as the landlords draw up the new agreements.
• Action: Sign the new rental agreement for the swap apartment and check the rent, service charges and term carefully.
• Tip: Compare the new conditions with your previous agreement. An adjustment of the rent is possible.

Step 7: Document the handover protocols

• When: On handover day, before you hand over the keys.
• Action: Document the condition of both apartments in writing and with photos in the handover protocol.
• Tip: Record defects precisely. A complete protocol protects both sides against unjustified deductions from the deposit.

Step 8: Plan a coordinated move

• When: In the final weeks before the handover date.
• Action: Coordinate the moving date of both households so that key handovers and move-ins follow on smoothly.
• Tip: Plan a buffer day in case one of the two moves runs late.

Where can you find a suitable swap apartment in Zurich and across Switzerland?

Finding swap partners has become easier in Switzerland since specialised platforms and property portals started allowing swap listings. A meaningful swap listing with photos, number of rooms, location and the profile you are looking for noticeably improves your chances.

The following channels are available for finding a swap apartment in Zurich and other Swiss cities:

• Specialised swap platforms: Portals that deal exclusively in apartment swaps. Their inventory is heavily geared towards the German market, so Swiss listings are correspondingly thinner.
• Swiss property portals: The large portals do not run a dedicated swap category, but individual listings flag the swap request in the title. Searching for «Wohnungstausch» or «Tauschwohnung» surfaces those.
• Neighbourhood groups and local apps: Complementary channels that work particularly well for locally anchored swap requests.

Make sure your swap listing names not only photos and the number of rooms, but also the exact district, the public transport connections and the size you are looking for. A complete listing saves both sides time.

What can you do if the landlord refuses the swap?

If the landlord refuses the apartment swap, no legal route will force one. There are alternatives, though, that still make a change of home possible.

First, the unwelcome news: because there is no statutory entitlement to a swap for residential apartments, a refusal cannot be challenged. The conciliation authority cannot substitute for consent that has been withheld. Ask for the reasons instead, and check whether the concerns can be addressed, for example with a debt collection register extract, proof of salary and references for your swap partner.

If that leads nowhere, the regular route remains: you give ordinary notice under Art. 266c CO and look for the new apartment on the open market. If you want to move out earlier than the notice period allows, you can propose a reasonable replacement tenant. Under Art. 264 CO you are then released from your obligations early, provided the proposed person is solvent and willing to take over the rental agreement on the same terms. The landlord does not have to accept that person as the new tenant, but can then no longer charge you the rent either.

The Swiss Tenants’ Association (Mieterinnen- und Mieterverband, MV) can advise you if you are unsure whether a proposed replacement tenant counts as reasonable.

Your options at a glance:

• Ask for the reasons behind the refusal and address the concerns directly
• Give ordinary notice under Art. 266c CO and keep looking on the open market
• To move out earlier, propose a reasonable replacement tenant under Art. 264 CO
• Contact the Swiss Tenants’ Association for legal advice

What to bear in mind when moving after an apartment swap

An apartment swap ends with two moves that are ideally scheduled for the same date. Carefully documented handover protocols for both apartments and a checklist for the apartment handover prevent deductions from the deposit. Because the handover date is set by the notice period under Art. 266c CO, the time available to both households stays tight. A fully completed handover protocol is in both sides’ interest, because only what is recorded in it can later serve as a basis for deductions. For that reason, plan both moves with a buffer day in between, so that delays on one side do not block the entire sequence. The checklist for the apartment handover helps you approach this final step in a structured way.

Frequently asked questions about apartment swaps

How does an apartment swap work?

An apartment swap runs in eight steps: create a swap listing, find a swap partner, contact both landlords in writing, organise mutual viewings, submit notice in writing under Art. 266c CO, conclude the new rental agreements, document the handover protocols and plan the coordinated move. The most critical step is obtaining the landlord’s consent early, because without it the whole process stalls. Allow three to six months in total from the first listing to moving in.

How does the move work with a swap apartment?

In an apartment swap, both parties schedule their moves for the same date or for consecutive dates, so that the key handover for both apartments runs smoothly. Both sides draw up their handover protocols at the same time, which requires good advance coordination. A small buffer day between the moves can help if one side runs into delays.

What are the advantages and disadvantages of an apartment swap?

An apartment swap offers several advantages: no vacancy, because both parties move at the same time, a lower risk of ending up without a follow-on home, and a coordinated transition without paying double rent. The disadvantages lie in the dependence on both landlords’ consent, the difficulty of finding a suitable swap partner, and the requirement that both households match up in terms of timing. Anyone who needs flexibility will find less room for manoeuvre in an apartment swap than in a regular search for a home.

How high is the success rate for apartment swaps?

An exact success rate cannot be stated, because no official statistics on apartment swaps in Switzerland are available. Success depends heavily on the size of the apartment, the location and the cooperation of both landlords. In cities with a tight housing market such as Zurich or Geneva, an apartment swap can be a sensible alternative to a regular search for a home, because both parties have a secured destination at the same time.
