Prohibited requests

Anti-discrimination limits

You cannot request or consider: medical history, disability status, criminal record, ethnic origin, religion, sexual orientation, family status (married/single/pregnant), political affiliation, or union membership. Requesting these documents exposes you to discrimination complaints.

Common violations to avoid:

  • Asking if the candidate plans to have children
  • Requesting a certificate of good conduct (criminal record extract)
  • Asking about health conditions or disabilities
  • Requesting information about religion or philosophical beliefs
  • Asking about welfare benefits as a disqualifying factor

If a refused candidate believes you discriminated against them, they can file a complaint with Unia or the regional equal opportunities body. Situation testing is regularly conducted.

Warning

Keep candidate files secure and destroy them after the selection process is complete. Under the GDPR, you cannot retain personal data longer than necessary for the purpose for which it was collected.

GDPR and data protection

The General Data Protection Regulation (GDPR) applies to tenant selection:

  • Data minimisation: collect only the data strictly necessary for assessing the candidate’s suitability
  • Purpose limitation: use the data only for tenant selection, not for other purposes
  • Storage limitation: destroy candidate files after the selection is complete (keep only the selected tenant’s file)
  • Transparency: inform candidates of what data you collect and why
  • Security: store candidate data securely (locked cabinet or encrypted digital files)

For landlords using a property management agency, ensure the agency complies with GDPR requirements.
