Buying Property in Castelldefels or Gavà Mar: Why a Building Inspection Matters

When you buy property in Spain, the condition of the building matters as much as the location.

This is especially true in Castelldefels, Gavà Mar and the Barcelona coastal area, where many homes are in established residential zones. Some buildings are modern. Others have been renovated, extended or used for many years by different owners.

Before buying, it is important to understand whether the building has passed the ITE, or Inspección Técnica del Edificio.

The ITE is a technical inspection of the building. It helps confirm whether the property is safe, well maintained and compliant with the rules that apply in Catalonia.

What is the ITE?

The ITE is a technical inspection for residential buildings.

It checks the general condition of the building. This can include the structure, façades, roof, common areas and other elements that may affect safety or habitability.

In Catalonia, residential buildings generally need to pass this inspection before they reach 45 years of age. The age of the building is usually based on the information in the cadastre.

After the inspection, the owner or community of owners applies for the Certificate of Aptitude, known in Spanish as the Certificado de Aptitud. This certificate confirms the result of the inspection and the administrative status of the building.

Why the ITE matters when buying a property

The ITE is important because it can affect the real cost of the property.

A home may look good during a viewing, but the building may still have technical issues. These can include façade problems, roof repairs, structural defects or maintenance works planned by the community of owners.

If the building has not passed the ITE, or if the report shows defects, the buyer should know this before signing.

This is not only a legal detail. It is also a financial question. Future repair works may lead to extra community fees or special payments from owners.

For apartments in Castelldefels or Gavà Mar, this can be very relevant. You are not only buying the private home. You are also becoming part of the building and its community.

Does the ITE apply to villas and houses?

Sometimes, yes.

The rules can depend on the type of property and its location. In Catalonia, residential buildings must generally undergo the inspection before reaching 45 years of age. Some single-family houses may be treated differently, especially if they are separated from public roads, public spaces or neighbouring plots.

This is why each property should be checked individually.

In areas such as Bellamar, Montemar, La Pineda, Castelldefels Playa and Gavà Mar, many buyers look at villas or semi-detached houses. These homes may have extensions, terraces, pools or older structural elements. A technical review can help avoid surprises.

What happens if the ITE has not been done?

If the building is old enough to require an ITE and the inspection has not been completed, this should be clarified before the purchase.

The issue may not always stop the sale, but it should never be ignored.

The buyer should understand why the ITE is missing, whether it is legally required, whether the community of owners is already dealing with it and whether future repair costs are expected.

In Catalonia, when a home is sold, the seller may be required to provide the ITE report and the Certificate of Aptitude if the building is subject to this obligation. In some cases, the buyer may formally waive the delivery of this document, but this should be considered very carefully.

A missing ITE can become a problem after the purchase. It can also affect negotiations, financing or future resale.

What if the ITE shows defects?

An ITE report can show different levels of defects.

Some may be minor and easy to solve. Others may require important repair works. Serious issues can affect safety and may require urgent action.

This does not always mean that you should not buy the property. But it does mean that you should understand the cost, timing and responsibility before signing.

If works are already planned by the community, you should check whether they have been approved, how much they will cost and who will pay. In many cases, the new owner may become responsible after completion.

This is one of the reasons why good due diligence is so important.

Why this is important in Castelldefels and Gavà Mar

Castelldefels and Gavà Mar are highly desirable areas. Buyers often focus on views, gardens, terraces, beach access and proximity to Barcelona.

These things are important. But the technical condition of the property is just as important.

A well-located apartment in an older building may still require façade works. A villa with a beautiful garden may have parts that were added years ago and need checking. A property close to the sea may also need more maintenance due to humidity, salt and weather exposure.

A good purchase is not only about choosing the right area. It is about knowing exactly what you are buying.
