Law 8/2026

What happens if my property has asbestos?

Finding out your property has asbestos isn't the end of a sale or rental. The certificate documents where it is, what condition it's in and what risk it poses, and from there you have several options. Here's what each result means and how it usually plays out in practice.

What exactly does the certificate document when it finds asbestos?

After the visual inspection, the report records which elements show presence of visible asbestos (for example, a fibre cement roof, a drainpipe or a water tank), what condition they're in, and what level of risk they represent as they currently stand. It's not a laboratory analysis — it's a visual assessment by the professional who signs the certificate.

Does the certificate block the sale or rental of the property?

No. Finding asbestos doesn't block the transaction. What the law requires is that this information be recorded in a certificate and disclosed to the other party; the sale or rental can still go ahead with the buyer or tenant properly informed.

How does this usually affect negotiations with the buyer or tenant?

In practice, having the result in writing usually reassures both sides: the buyer or tenant knows exactly where they stand and can ask questions or assess the condition with more clarity. In some cases this can affect the price or the terms agreed, but that's negotiated case by case rather than set by the law.

Is well-preserved material the same as deteriorated material?

No. Asbestos-containing fibre cement that is intact, with no cracks or crumbling, and that won't be disturbed, generally poses a low risk and doesn't usually require any urgent action. The problem arises when the material is degraded, cracked or friable (crumbles easily), because that's when the risk of releasing fibres into the air increases.

If the material is deteriorated, what's recommended?

As a matter of general good practice, if the certificate flags material in poor condition, it's sensible to have a specialised asbestos company assess it to decide whether intervention or removal makes sense. This doesn't necessarily mean Law 8/2026 requires removal before selling or renting — the implementing regulation that should clarify these points is still under development.

If I have asbestos, what options do I have as an owner?

Essentially two: sell or rent with the certificate reflecting the situation as it stands, disclosing it to the other party, or consider removal beforehand if the material is deteriorated or you'd rather clear any doubt before putting the property on the market. Neither is mandatory in itself based on what we currently know about the law — it depends on your situation and priorities.

Does having asbestos lower the property's value?

There's no fixed rule: it depends on the material's condition, the property's location and how each buyer or tenant weighs it. What is certain is that hiding the information isn't a legal option, and having the certificate ready from the start usually makes for a more transparent negotiation with no last-minute surprises.

Can I rent or sell without having removed the asbestos?

Yes, generally you can if the material is in adequate condition and the certificate reflects that. What you need is the document certifying the property's actual situation; the decision to remove it is separate and can be made before, after, or never, depending on your case.
