Building or renovating a home in the Costa Blanca is a dream for many foreigners, but the process involves legal, cultural and technical aspects that are often very different from those in their home countries. Understanding these requirements from the beginning makes the experience much easier and ensures your investment is safe.
At La Quinta Fachada, we help international clients through every stage of the process, from choosing the right plot to handing over the keys to a tailor-made Mediterranean home.
Why the Costa Blanca attracts so many international buyers
The Costa Blanca is one of the most sought-after destinations in Spain, thanks to its climate, quality of life and international connections. Towns such as Jávea, Dénia, Altea, Moraira or Benissa attract buyers from the UK, France, the Netherlands, Germany and Scandinavia.
Foreign buyers not only want to enjoy the Mediterranean lifestyle, but also see real estate in the area as a long-term investment.
Key requirements for foreigners who want to build or renovate in the Costa Blanca
1. NIE (Número de Identificación de Extranjero)
This tax identification number is essential to buy property, sign contracts or pay taxes in Spain. Without it, no legal transaction is possible.
2. Building licences and planning permissions
Spanish regulations are strict and vary from one municipality to another. Before starting any project, it is vital to obtain the correct licence (obra mayor or obra menor). Failing to do so may result in fines or even demolition orders.
3. Local architects and technical team
Working with architects and engineers based in the Costa Blanca ensures compliance with local regulations and guarantees that the design is suited to the climate, topography and Mediterranean lifestyle.
4. Reliable builder
Choosing the right builder is one of the most decisive steps. It is important to check their previous work, request detailed budgets and make sure they have the right resources to complete the project.
5. Taxation and legal advice
Depending on your nationality and whether you are resident in Spain, the tax implications will differ. A lawyer specialising in real estate and international clients can prevent future problems.
