Swiss Apartment Application: Documents Checklist 2026

What documents do you need to apply for a flat?

The property manager (Verwaltung) wants to see quickly whether you will pay the rent reliably and who they are dealing with. Applications therefore almost always go through their application form – what Germans call a «Selbstauskunft». What to include, and what is only needed when the lease is signed:

Debt collection extract: where to order it and what it costs

The debt collection register extract shows whether any debt enforcement proceedings (Betreibungen) or certificates of loss (Verlustscheine) are recorded against you – for a landlord the key signal that you can pay. Order it from the debt collection office for your place of residence: at the counter, in writing or, at many offices, online. The fee is set nationally. Note: the extract only covers the period since you moved into that office’s district, five years at most. If you moved recently, also order one from your previous place.

What may a Swiss landlord ask – and what not?

A landlord may only ask for data needed to choose a tenant and draw up the lease. The Federal Data Protection and Information Commissioner (EDÖB) assumes two steps: first everyone applies with the form; then the landlord collects proof and references only from the shortlisted applicants. The key questions at a glance:

References: when may the landlord call?

Landlords may not check references behind your back: the form must state clearly that the current landlord or employer you list may be contacted, and giving them is voluntary. They may call only the people you named, only once you are seriously in the running, and only to confirm what you stated (EDÖB). Tell your referees in advance that a call may come – a prompt, friendly confirmation is worth a lot.

Do you need a cover letter?

No, it is optional. It helps most when your profile needs explaining: a new job, probation period, studies, arrival from abroad. Keep it short and answer three questions:

1. Who is moving in? Name, job, who moves in with you (people, perhaps a quiet pet).
2. Why this flat? An honest, concrete reason: close to work, school, family.
3. Why are you reliable? Permanent job, regular income, rent paid on time so far.

Many property managers expect the gross rent to be no more than a third of income. If you are above that, for example as a student, a second person can co-sign with joint liability or act as guarantor; the landlord may ask them for the same financial details.

How do you make your application stand out?

1. Prepare. Order the extract as soon as you are seriously looking and keep everything in one PDF (“Application_Mustergasse5_Smith.pdf”), not eight loose phone photos.
2. Be quick. Submit on the day of the viewing, while you are fresh in the manager’s mind.
3. Be complete. Go through the checklist before sending; every adult who co-signs needs their own details and their own extract.
4. Stay reachable. Phone and e-mail clearly visible; answer follow-up questions the same day.
5. Stay honest. False details surface with the extract or the reference call and can cost you the lease.

You got the flat – what happens next?

Next come the lease and the rental deposit (Mietkaution). The deposit is at most three months’ rent and goes into a blocked account in your name (Art. 257e CO). Only now may the landlord ask for your ID copy, payslips and, if needed, the original extract. If the initial rent seems too high, you can, under certain conditions, challenge it at the conciliation authority (Schlichtungsbehörde) within 30 days of taking over the flat (Art. 270 CO).
