More information does not automatically mean better tenant selection. Can a form be fairer and legally more secure even if it deliberately contains fewer questions?
ARegistration form for prospective tenantsshould therefore not look for the “best” personal profile. It should only record information that is factually relevant to the contractual party, occupancy, use of the apartment or ability to pay. The decisive structure consists of two stages:Basic data after the viewing, additional evidence only after serious consideration.
Why neutrality in the registration form is mandatory today
What information does a landlord really need in order to fairly examine an application? During the viewing, an interested party may mention her marital status. This information is usually irrelevant for occupancy or ability to pay and should therefore not be included in the form without being checked. What is crucial is a clear purpose for each field.
A neutralRegistration form for prospective tenantsacts like a filter: it holds back personal details that do not clarify anything for the tenancy and concentrates the selection on factual criteria. The structure follows a Two-stage principle. After the inspection, only basic data is recorded. Additional evidence only comes into question if a person is seriously considered.
TheFederal Data Protection and Information Commissioner, EDÖB, classifies such a form as processing of personal data according to the Swiss Data Protection Act. Data collection is permitted if it uses objective criteria to help select a suitable tenant.Die Empfehlungen des EDÖB zu Anmeldeformularen für Mietwohnungenoffer practical guidance for this.
Scarcity increases the pressure, but not the leeway
A uniform review process becomes particularly important for many applications. At the beginning of 2025 in Switzerland there were48,455 empty apartments, correspondingly1.00 percent of the total stock. At the same time, there was a trend towards stricter selection criteria, as documented by the Federal Statistical Office regarding the number of empty apartments.
Additional personal information does not automatically make the decision better. It becomes comparable if all applicants are assessed according to the same rent-relevant criteria. These include contractual capacity, appropriate occupancy, appropriate use and verifiable ability to pay.
Practical rule:Don't ask what interests you personally. Just ask what you need to objectively assess for this rental property.
A neutral form supports both sides. Landlords can document their decision in a comprehensible manner, limit questions and explain the selection to other parties involved. Data protection and fairness are therefore part of an orderly rental process.
The basis, mandatory fields for a legally compliant application
What information does a landlord really need in order to assign an application and process the form correctly? The first part of the form should contain the smallest sensible data set. Each mandatory piece of information receives a brief statement of purpose. For people who sign the rental agreement or guarantee a rental party, this includes in particularSurname, first name, date of birth, address and telephone number. The current FDPIC information sheet distinguishes necessary identification from unnecessary data collection.
What belongs in the first part of the form
Surname and first nameserve to identify the future contracting party. Record these details for every person who is to sign the tenancy agreement. In the case of a guarantee, only request the data from the person actually acting as guarantor. Anyone without a contractual connection is not automatically recorded.

are sufficient for the planned occupancyNumber of people moving in and number of childrenAlso ask about the intended use of the apartment. An existing or planned sublease arrangement only belongs in the form if it is relevant to the specific rental property. This keeps every field aligned with the apartment and the selection process.
| Field name | Purpose / Relevance |
|---|---|
| Surname and first name | Assignment to the future contracting party |
| Date of birth | Distinguishing between applicants with the same name |
| Address | Correspondence |
| Phone number | Follow-up questions and scheduling coordination |
| People in the household | Assessment of the planned occupancy |
| Number of children | Material connection to the occupancy |
| Apartment Use | Clarification of the intended use |
| Existing or planned sublease | Assessment of a relevant usage relationship |
| Profession, occupation and employer | Assessment of the professional situation, insofar as necessary for the selection |
| Information on creditworthiness | Assessment of whether the rent appears affordable |
Purpose notices make mandatory fields understandable
A field such as "Employer" should not appear without an explanation. Add a note stating that this information is used solely to assess the applicant's professional situation or ability to pay. This allows applicants to understand the context and to distinguish mandatory fields from optional information.
Precise wording also helps when it comes to use of the property. "How is the apartment to be used?" relates directly to the rental property. A blanket question about private living circumstances, by contrast, opens up unnecessary scope for interpretation. Explaining the purpose makes the process more understandable and supports a consistent assessment.
The Two-Stage Principle for Sensitive Data
The most important structural step is the temporal separation of data collection. Aneutral Swiss registration form#### Die Sicht der Mieterverbände Mieterverbände kritisieren die Praxis der Datensammlung bei Wohnungsbewerbungen seit Jahren.EDÖB zum zweistufigen Vorgehen bei Mietbewerbungenprevents sensitive information from serving as a filter unnecessarily early.
Stage one after the viewing
After the viewing, a compact, property-specific set of data is sufficient. It contains the identity and contact details of the future contracting parties, the number of people moving in, information on the intended use, and details relevant to creditworthiness.
Timing is crucial. Historically, the FDPIC explanatory notes document that application forms are typically completed after the apartment viewing, before the property management or owner makes a selection. A general waiting list without a specific rental property, by contrast, normally requires only the surname, first name and address, as thefrüheren EDÖB-Erläuterungen zu Mietanmeldeformularenis evident.
Stage two when seriously considering
Only at the shortlist stage should you request supporting documents to verify an application that is already relevant. These may include details of the applicant's employment situation, proof of income or a current extract from the debt collection register. Do not ask across the board about all private financial circumstances when specific proof of the ability to pay is sufficient.
An extract from the debt collection register lists the debt enforcement proceedings opened against the person concerned over the past five years. It can be requested online, in writing or in person from the competent debt collection office in the canton of residence. The Swiss government portal generally quotes a fee ofCHF 17 plus postage.Die Informationen des Schweizer Behördenportals zum Betreibungsregisterauszughelp applicants obtain the document.
As a rule, only contact those references that the prospective tenant has provided themselves. Essentially, have the information already given confirmed, rather than obtaining comprehensive information about private circumstances.
For the digital implementation, you can organise the form, the purpose statement and the subsequent upload step separately. Explain in yourDatenschutzrichtlinie für digitale Formularewhich data are collected when and who processes them.
Setting limits: what you may not ask
The line is not drawn between "private" and "business", but betweenrelevant to the tenancyand irrelevant. Income, the employer and a current extract from the debt collection register can play a legitimate role in Swiss practice. By contrast, a question about membership of the Tenants' Association is considered inadmissible, as theMieterverband zur Wohnungssuchestates.
| Category | Neutral / Permitted | Discriminatory / Prohibited |
|---|---|---|
| Income | "What information demonstrates that the total rent is affordable for you?" | "How much private wealth do you have in total?" |
| Occupation | "Who is your employer?" | "What is your social status?" |
| Occupancy | "How many people will be moving in?" | "Are you even planning a traditional family?" |
| Use | "Is a sublet planned?" | "What are your private lifestyle habits?" |
| References | "May we contact the reference you have provided?" | "Which people in your circle may we approach on our own initiative?" |
| Association membership | No question required | "Are you a member of the Tenants' Association?" |
| Personal characteristics | Only property-related information | Routinely recording religious affiliation, marital status or data of uninvolved persons |
Replacing typical poorly worded questions
The question aboutmarital statusorreligious affiliationdoes not belong in a neutral standard form. Data concerning persons who are not joining the tenancy agreement as a party may likewise not be requested routinely without a specific purpose. A family situation only becomes relevant where it relates to occupancy or the handling of the contract.
The process is also limited when it comes to references. Do not contact previous landlords, employers or neighbours on your own initiative whose contact details you have researched yourself. Ask the interested party to provide a suitable reference and limit your enquiry to confirming specific details.
Anyone designing digital forms should review the purpose of each sensitive category and describe the processing transparently. TheDatenschutzhinweise von VorsorgePlaner.onlineoffer additional guidance for clear and understandable privacy notices. A clear process around theWohnungsbesichtigung und ihre wichtigen Punktealso helps when preparing the application.
Template for your neutral rental application form
A good template does not begin with a long list of questions, but with the specific rental property. Enter the address, the designation of the apartment and the intended start of the tenancy. This makes it clear that the application relates to a specific property and does not serve as a general collection of personal data.
Sample structure to copy
Rental property
- Address and designation of the apartment
- Desired start of tenancy
- Note: "This information will be used to process your application for the rental property specified."
Future contracting parties
- Surname
- First name
- Date of birth
- Current address
- Telephone number
- Email address
- Indication of whether the person will sign the tenancy agreement or act as guarantor for a tenant party
Household and use
- Number of people moving in
- Number of children
- Intended use of the apartment
- Existing or planned sublet arrangement, if relevant to the rental property
Professional situation and ability to pay
- Profession or occupation
- Employer
- Information that can demonstrate the affordability of the total rent
Transparency and confirmation
- Note on the purpose next to each sensitive field
- Note that additional supporting documents will only be requested once an application is under serious consideration
- Consent to contact the references provided by the applicant
- Date and signature
This structure can be used on paper or digitally. Mandatory fields should only be used where there is a direct, factual connection. A separate upload field for creditworthiness documents keeps the first application stage lean and prevents all interested parties from having to submit the same sensitive documents straight away.
For a customisable Swiss version, you can use theVorlage für eine Wohnungsbewerbungas a practical starting point. Before using it, check each field against the specific apartment, the planned occupancy and the selected decision criteria.
Conclusion and next steps for landlords
Many landlords worry that a restrained form could cost them a good tenant. In practice, the greater risk often arises not from missing information, but from inconsistent selection, unnecessary third-party information and questions with no clear link to the tenancy.
Therefore, revise your existing form in this order:
- Define the rental property:Remove general questions that do not serve a specific tenancy agreement.
- Shorten the first stage:After the viewing, record only identity, contact details, occupancy, use and relevant ability to pay.
- Separate the second stage:Request supporting documents and references only once an application is under serious consideration.
- Document the decision criteria:Determine before the selection how completeness, affordability, capacity to enter into a contract and suitable use will be assessed.
- Explain sensitive fields:Add notes on the purpose and refrain from asking about marital status, religious affiliation, association membership or people not involved.
A neutral form does not make the decision for you. It ensures that you make the same decision in a comprehensible and objective way.
Also check whether your digital filing system, access rights and deletion practices match the data collection you have chosen. A clear, two-stage process reduces unnecessary follow-up questions and protects both landlords and prospective tenants from avoidable conflicts.
