This article explains, in clear language, when conduct may amount to discrimination, what evidence to collect, deadlines to meet and steps to file a complaint or request measures with competent authorities. We include practical examples, guidance on official forms and tips for communicating with the landlord without harming your position. The goal is to help tenants in Portugal act confidently and preserve their right to fair treatment.

What is discrimination in renting?

Discrimination in renting happens when a landlord treats an applicant or tenant unequally for prohibited reasons (such as origin, sex, marital status, age or family). Not every difference in treatment is illegal, but Portuguese law sets limits and protects access to housing.[1]

In many cases, documentary evidence is decisive to support a complaint.

Common mistakes that harm tenants

  • Selective rent increases applied without written justification.
  • Refusing to rent for personal reasons that amount to discrimination.
  • Carrying out inspections or entries without prior notice or consent.
  • Retaliation after the tenant complains about habitability conditions.
  • Failing to keep records of communications, receipts and relevant messages.
Always request written confirmation of landlord decisions and keep copies.

How to act step by step

If you believe you were discriminated against, follow clear steps to protect your rights and build a solid case.

  1. Note dates, people involved and collect evidence (messages, photos, receipts).
  2. Contact the landlord in writing and request clarification, keeping a formal and objective tone.
  3. Consult applicable legislation and fill in official forms when necessary.[1]
  4. If there is no solution, submit a complaint to the Balcão do Arrendatário e do Senhorio (BAS/BNA) or proceed to court following official guidance.[2]
  5. Consider legal support to assess urgency, deadlines and precautionary measures.
Respond to formal notices within deadlines so you do not lose procedural rights.
