Renting an apartment in Switzerland when you are moving from abroad

Why arriving from abroad is the real handicap

The shortage is extreme — 0.1 % vacancy in the city of Zurich, 0.34 % in the canton of Geneva (Federal Statistical Office, 1 June 2025) — so an agency receives dozens of files for one flat and keeps the ones that are complete on day one.

Someone who already lives in Switzerland has those documents in a drawer. Arriving from abroad, you are asked for papers that do not exist yet in your name, in a language you may not read, on listings published on portals you have never heard of. That gap — not your income — is what usually costs you the flat.

The documents a Swiss agency expects

Identity document and residence permit (B, C or L) — or your employment contract if the permit is still being issued.

The last three payslips, or the contract stating your salary. Agencies apply the rule of thirds: gross annual income of at least three times the annual rent. It is a practice, not a law, but it is applied as if it were.

An extract from the debt collection register (Betreibungsregisterauszug / extrait des poursuites), dated less than three months. It costs 17 to 18 CHF at the local office, around 30 CHF online.

Liability insurance (RC ménage / Privathaftpflicht) is frequently asked for at file stage, not only after signature.

You cannot get a Swiss debt extract before you live here

The extract is issued by the debt collection office of the municipality where you are registered. Before you are registered, it simply does not exist for you — asking for one is not an option.

What works instead: a certificate of no debt from your country of origin, translated if needed, plus a short cover letter explaining that you have just arrived. Add your employment contract: for an agency, a signed contract in Switzerland answers the same question the extract answers.

The deposit: capped, and it stays yours

The deposit cannot exceed three months of net rent — article 257e of the Swiss Code of Obligations. Net rent means rent without the service charges.

It must be paid into a blocked account opened in YOUR name, at a bank, not into the agency's account. The money remains yours; neither side can withdraw it alone.

A rental deposit insurance (Mietkautionsversicherung) is an alternative if you cannot block that amount. You pay an annual premium instead — the premium is not a deposit and is never refunded.

Two deadlines nobody tells you about

The initial rent can be challenged within 30 days — and that period starts when you receive the keys, not when you sign (article 270 CO). Several cantons require the landlord to hand you an official form stating the previous tenant's rent; where that form is mandatory and missing, the lease terms can be contested.

Defects found after the handover inventory can still be reported by registered letter within roughly ten days. After that, they are considered accepted — and may be charged to you when you leave.

Being fast matters more than being perfect

Around 70 % of enquiries on a listing arrive in the first days. A complete file sent six hours after publication beats a perfect file sent two days later.

Practical consequence for someone abroad: prepare the folder before you start looking, and get notified the minute a listing appears rather than browsing portals once a day.
