Tenants in France: unsanitary risks from DPE

Energy performance (DPE) 2 min read · published September 11, 2025

Tenants in France may face unsanitary risks when a dwelling's energy performance is very poor (energy sieves) and defects promote mold, damp or lack of heating. Knowing your rights and the landlord's obligations allows you to act: gather evidence (photos, letters), request repairs, contact the departmental conciliation commission or bring the case before the judicial court[1] if necessary. Keep all documents, send requests by registered mail with acknowledgement of receipt, note dates and ask for an expert opinion if needed. Local assistance may exist depending on your municipality; check with the town hall or on Service-public[2].

Keep all documents and send requests by registered mail with AR.

What to do in practice

Act in clear steps: inform the landlord, document the problems, request repairs and, if needed, initiate an amicable or judicial procedure.

Gather evidence

  • Photos and videos of affected areas (photo)
  • Medical reports or attestations if health is affected
  • Copies of the energy performance diagnosis (DPE)
  • Heating bills and consumption records
Dated and varied evidence strengthens your case.

Request repairs from the landlord

  • Send a written request by registered mail with AR (file)
  • Set a reasonable deadline for repairs (days)
  • Request a joint visit or an independent expert assessment if disputed (repair)
Respect deadlines to preserve your legal rights.

Possible remedies

  • Refer the case to the departmental conciliation commission to seek an amicable solution
  • Bring the matter before the judicial court if conciliation fails or in urgent cases
  • Request protective measures if there is a health danger
Amicable procedures are often faster and less costly than trials.

FAQ

How can I prove that unsanitary conditions are linked to a poor DPE?
Gather the DPE, photos, bills, attestations and, if possible, a health assessment to establish the connection between energy performance and issues like damp or heating failures.
Can the landlord be forced to carry out repairs?
Yes, the landlord must ensure the dwelling meets habitability and safety standards and can be ordered by conciliation or court decision to perform necessary repairs.
What deadlines apply?
Act as soon as the problem appears: send a formal notice by registered mail and follow the deadlines set by authorities or the court for each step.

How-To

  1. Record facts and dates precisely and gather evidence (photos, videos, bills, DPE).
  2. Send a formal notice to the landlord by registered mail with acknowledgment of receipt.
  3. Request an independent expert assessment if the landlord disputes the condition.
  4. Refer to the departmental conciliation commission and, if necessary, bring the case before the judicial court.
