Certificate of Presence or Absence of Asbestos
Identify the presence or absence of visible asbestos in your property and have the necessary documentation to sell or rent with peace of mind.
The Certificate of Presence or Absence of Asbestos is the technical document that confirms the possible presence or absence of materials with visible asbestos in a building at the time of the inspection.
Law 8/2026, of 2 July, on the eradication of asbestos in Catalonia, provides for the issuance of this certificate when a property is sold or rented. Furthermore, in the case of property sales, the certificate must be recorded in the Land Registry.
Until the regulatory development of the Law is approved, the Agència de Residus de Catalunya establishes that the scope of application covers properties built before 2002.
If materials with visible asbestos are detected, the certificate must indicate, at a minimum:
- Its presence and location.
- Its observable state of conservation.
- The potential risk posed to people.

Inspection scope
The inspection is purely visual and is limited to the property in question. It does not include excavations, dismantling, handling of materials, sampling or laboratory tests.
For this reason, the certificate does not rule out the presence of asbestos in hidden elements or in areas that are not accessible during the visit.
When you might need it
You should take this certificate into account when the following conditions apply:
Sale or rental + property built before 2002 + Catalonia
The final content and scope of the certificate are pending the regulatory development provided for in the Law. Until then, the case will be handled in accordance with the regulations and interpretative criteria currently in force.
