Tenant Self-Disclosure: What Landlords May Ask – and What They May Not

What the tenant self-disclosure is – and that it remains voluntary

The tenant self-disclosure is a questionnaire with which the landlord, before the tenancy agreement, gathers information on a prospective tenant's suitability – their identity, their ability to pay and the intended use of the dwelling. It is not required by law and is in principle voluntary for the prospective tenant: there is no obligation to provide it.

In practice, however, the disclosure is nonetheless the norm, because the landlord may make their decision dependent on a meaningful self-disclosure. The legal guardrail is provided by the General Data Protection Regulation (GDPR – the EU's data protection law, known in German as the DSGVO): personal data may only be collected for specified, legitimate purposes and only to the extent necessary – the principle of data minimisation (Art. 5 GDPR). Translated, this means: what may be asked is what is genuinely needed for the specific tenancy – nothing more.

These questions are permissible

The information needed depends on the application stage. Necessary contact and organisational details come first for a viewing. Only after concrete rental interest may further details about the proposed contracting parties, number of occupants and ability to pay be needed.

The Data Protection Conference’s January 2026 guidance allows consideration of relevant employment and employer information, net income or a sufficient income threshold at the appropriate stage. Length of current employment and former landlords’ contact details do not belong in the standard questionnaire. Where a public body pays the rent fully and directly, additional questions about personal income are unnecessary. Each question must be needed for the actual purpose; blanket consent does not replace that assessment.

These questions are impermissible – and why

Impermissible are questions with no relation to the tenancy as well as those that intrude into specially protected data or into characteristics giving rise to discrimination. The yardsticks are the General Equal Treatment Act (AGG – Germany's anti-discrimination law) and the protection of special categories of personal data under the GDPR. Off-limits are in particular:

• Pregnancy, the desire to have children and family planning.
• Religion and philosophical beliefs.
• Party membership and political orientation.
• Ethnic origin, nationality or citizenship.
• Intention to marry and relationship status.
• Sexual orientation.
• Membership of a trade union, tenants' association or clubs.
• Health and disabilities.
• Previous convictions – as a rule, since they are immaterial to a tenancy in the absence of a specific connection.

The reason is twofold: the AGG protects against disadvantage on grounds such as ethnic origin, religion, sex, disability, age or sexual identity; and the GDPR prohibits the collection of sensitive data without a sound legal basis. Such questions therefore have no place in a self-disclosure.

The right to lie in response to impermissible questions

What happens if a landlord nevertheless asks an impermissible question? Here the so-called right to lie applies in practice: a prospective tenant need not answer an impermissible question truthfully, and a deliberately false answer remains without consequences. The landlord cannot later, for instance, rescind or terminate the tenancy agreement because a tenant gave a false answer to the – impermissible – question about a pregnancy. The rationale is compelling: anyone who was not even allowed to collect a piece of information may derive no rights from an incorrect answer.

Conversely, the following applies: permissible questions must be answered truthfully. Anyone who deceives here – for example regarding income or an ongoing insolvency proceeding – must reckon with consequences (see the final section). For landlords, a simple conclusion follows from this: a cleanly designed form confined to permissible questions is not only compliant with data protection law but also the more robust basis for a decision.

Which data, and when? The tiered model of the Data Protection Conference

The Data Protection Conference’s version 2.0 guidance, January 2026, distinguishes three phases:

• Viewing: Necessary contact and organisational data, without a standard financial investigation or identity-document copy.
• Concrete rental interest: Necessary information about intended occupation and ability to pay, initially as self-disclosure.
• Selection for the contract: Necessary evidence is checked for the selected, first-ranked applicant. A broad shortlist is not yet this final phase.

Access and deletion form part of the process. Delete information no longer needed when its purpose ends. Limited retention for legal defence requires a concrete basis; a blanket six-month period for every document and participant is not a general permission. Indefinite applicant archives or lists for later offers require their own appropriate foundation.

SCHUFA, proof of income and freedom from rent debt

Necessary income evidence may be examined for the applicant selected for the agreement. Irrelevant details can be redacted. Different income sources can require different suitable documents; a complete employment agreement is not a standard requirement.

A full credit-agency data copy under Article 15 GDPR contains excessive information and should not be required as a general proof. A focused creditworthiness document, where necessary, is different. Adequate existing evidence does not automatically justify an additional comprehensive investigation.

The current guidance says a certificate of no rent arrears must not be made compulsory, since the previous landlord has no general duty to issue it. Where proof is needed, suitable payment evidence limited to relevant transactions and appropriately redacted may be considered. Former landlords’ contact details do not belong in the enquiry.

False statements in response to permissible questions: the consequences

If a tenant deliberately gives a false answer to a permissible question and this information is material to the letting decision, serious consequences may follow. Two avenues are open to the landlord:

• Rescission for fraudulent misrepresentation (§ 123 BGB – section 123 of the German Civil Code): If the landlord would not have concluded the contract had they known the truth – for instance because of a concealed insolvency proceeding or invented income figures – they may rescind the contract and unwind it.
• Extraordinary termination (§ 543 BGB – section 543 of the German Civil Code): If the deception is so grave that the landlord cannot reasonably be expected to continue the tenancy, termination without notice may come into consideration.

What is always decisive is that the falsely answered question was permissible and genuinely carried weight for the decision. Trifling matters support neither rescission nor termination. This clear distinction – a permissible question with a duty of truthfulness on the one hand, an impermissible question with the right to lie on the other – is the core of a legally sound tenant selection. For the concrete enforcement in an individual case, legal advice is part of the process.
