The roof terrace is usually the whole reason someone buys a penthouse — and it is exactly the part of the purchase most likely to have a registration problem the rest of the flat doesn’t.
The terrace has to be registered, not just enjoyed
Exclusive use of a roof terrace is only legally secure if it is explicitly recorded as a private-use element in the building’s division horizontal deed. Without that specific registration, the space can technically remain a communal element the whole building has rights over, whatever the sales listing implies.
Later additions are the highest-risk scenario
A terrace or rooftop extension added after the building’s original registration is a genuine red flag. Unregistered later additions can mean the space was never properly legalised — in the worst documented cases, this has led to community disputes or even demolition orders for unlicensed rooftop structures.
How to actually check
Request the nota simple and the building’s division horizontal deed, and confirm the terrace or solarium is explicitly listed as an exclusive-use annex to your specific unit — not simply described in the listing as part of the property.
Expect higher community fees
Penthouses commonly carry a higher ownership coefficient reflecting the additional private space, which generally translates into higher community fees than a standard flat in the same building.
What to check with the community itself
Review the community statutes and recent meeting minutes specifically for any dispute or claim relating to the roof, terrace or shared building elements near the penthouse — these are consistently the most common flashpoints in buildings that mix standard flats with penthouses.

Frequently Asked Questions
Does a penthouse’s roof terrace automatically belong to the buyer?
Not automatically — exclusive use of a roof terrace needs to be explicitly recorded as a private-use element (uso privativo) in the building’s division horizontal deed. Without that registration, the space can technically remain a shared, communal element.
What if the terrace or a rooftop extension was added after the building was originally registered?
That is a real risk area. An unregistered later addition can mean the space was never legalised, which in the worst cases has led to disputes with the community of owners or even demolition orders for unlicensed rooftop structures.
How do I check if the terrace is properly registered to my unit?
Request the nota simple and the building’s division horizontal deed, and confirm the terrace or solarium is explicitly listed as an exclusive-use annex to your specific unit, not just described informally in the sales listing.
Does a penthouse have a different ownership coefficient to other flats?
Often, yes — penthouses commonly carry a higher ownership coefficient reflecting additional private space like a terrace, which typically means higher community fees than a standard flat in the same building.
Is there anything specific to check with the community of owners?
Yes — check the community statutes and recent minutes for any dispute or claim specifically about the roof, terrace or shared building elements near the penthouse, since these are the most common flashpoints in buildings with a mix of standard flats and penthouses.
