Buying a penthouse in Spain: terraces, roofs and rules
Quick answer
A penthouse often has a large terrace, and the key question is who owns it and who pays for the roof. The title and statutes decide, not the advert. Check the quota, the roof condition, the terrace rights and any planned works with your lawyer.
Applies toBuyers looking at a top-floor flat with a terrace or roof access.

§ 1Why a penthouse differs
A penthouse is the top-floor flat, often with terraces and sometimes with roof access. It is bought like any other apartment, but three questions weigh more: who owns the terrace, who pays for the roof, and what changes are allowed. This page belongs to the chapter in apartments, which explains the community and the usual checks.
§ 2The terrace
Advertisements often present a terrace as part of the flat. The legal position can be different. A terrace may be a private part of the unit, with its own surface in the registry description, or a common part that the title or statutes reserve for the use of the top-floor owner. The difference affects who may build, who pays for waterproofing and what happens at a sale. Compare the registry description, the cadastral record and the statutes.
§ 3The roof
The roof protects the building, and a leak is a source of disputes. Ask for the inspection reports, the history of repairs and any works voted or discussed. Ask who pays for the roof and the terrace floor, and whether the statutes allocate the cost. A penthouse can have more exposure to weather and more waterproofing needs than other floors.
§ 4Quota and fees
The quota in the title sets the share of common costs. A penthouse can carry a higher quota because of its size, though not always. Ask for the community budget and the last accounts. The reserve fund the law requires is a sign of how the building plans for repairs.
§ 5Changes and extensions
Do not rely on what the previous owner did. Enclosing a terrace, adding a pergola or building a room on the roof can need the agreement of the owners and municipal permission. The legal process section explains illegal works and what happens when they are discovered. If the flat already has an extension, ask for the permit, the community’s consent and the registry entry.
§ 6Lets and neighbours
Top-floor terraces attract holiday lets. The owners can limit or ban tourist rental by a qualified majority, and regional rules apply. Read the statutes and the minutes if you plan rental income, and read what neighbours say about noise.
§ 7Insurance
Ask the insurer whether the policy covers water damage from the roof and the terrace, and who is responsible. Keep the claims history with your file.
§ 8Before you commit
Visit on a rainy day if you can. Ask the administrator about leaks. Ask your lawyer to read the title and the statutes, and the registry extract, and to confirm in writing who owns what.
§ 9Views and light
A view is not a legal right. A neighbouring plot can be built on, and a new building can take the light that a penthouse has today. Ask the town hall what the plan allows nearby, and ask whether any project has been approved. This matters most for a flat that is priced for its outlook.
FAQRelated questions
Do I own the terrace?
It depends on the title and the statutes. A terrace may be private, or a common part reserved for your use. The registry description and the community papers show which, so ask your lawyer to read both before you pay.
Who pays for roof repairs?
Usually the community, as the roof protects the whole building, though statutes can assign some costs to the top-floor owner. Ask what the statutes say and whether the roof has leaks or a repair planned.
Can I build on or enclose the terrace?
Only with the right permissions. Changes to common parts need the community’s agreement and municipal permission. An unauthorised enclosure can be challenged later, so ask before you buy a home that already has one.
