The guide uses clear language so you can make informed decisions without being a legal expert. It includes action templates, safety tips and references to the rules that regulate habitability in Spain. We also indicate how to file a complaint with the court if appropriate.

What causes leaks and damp?

Leaks usually come from pipes, downspouts, roofs or deteriorated seals, while condensation-related damp is linked to insufficient ventilation or temperature changes. In any case, the presence of damp can affect the habitability of the dwelling and the tenant's rights under applicable law.[1]

In most cases, damp caused by the building structure should not be the tenant's direct responsibility.

What can the tenant do

Acting quickly and orderly increases the chances of a solution. Start by documenting and communicating the problem clearly and in writing.

  • Document the damage with photos and dates, and keep related receipts or communications.
  • Inform the landlord in writing and request a deadline for repair.
  • Request urgent repairs when there is a health or safety risk.
  • Contact emergency services or technical assistance if there is an imminent risk (e.g., electrical shorts due to water).
  • Keep a written record of all dealings and the landlord's responses.
Keep printed and digital copies of all communications and dated photos.

If the landlord does not act

If the landlord does not repair within a reasonable time you can demand formal intervention: certified notice, administrative claim or a lawsuit before the Court of First Instance as appropriate.[2]

Respond to any court notification within the deadlines to avoid harming your defense.

Useful evidence and documentation

The quality of your evidence is key. Include dated photos, technical reports if possible, and written communications with the landlord.

  • Photos and videos showing the evolution and extent of the damage.
  • Emails, certified mail or messages informing the landlord.
  • Estimates or invoices from technicians if you had to arrange urgent repairs.

Depende del origen: si la avería proviene de la estructura o instalaciones generales suele ser responsabilidad del propietario; si es por mal uso, del inquilino.
¿Puedo descontar el coste de la reparación del alquiler?
No es recomendable descontar sin acuerdo o resolución previa; lo adecuado es documentar y reclamar por escrito o acudir a vías legales.
