You have decided to buy in Spain, to live there, build your family home or let out a profitable flat? As the Spanish housing stock is ageing, you are probably thinking about renovation work without knowing where to start. This complete guide to renovating in Spain answers all the questions foreign buyers ask when they want a clear idea of what lies ahead: licences and permits, energy criteria, the budget to plan depending on the materials you choose, tax deductions and more. You will know everything about renovating property in Spain.
Even though it has slowed slightly in recent months, the Spanish property market remains very attractive, especially for foreign buyers. Local buyers, who often have less purchasing power than foreign investors, find it harder to cope with higher mortgage rates and stricter lending conditions. In this economic climate, foreigners come out ahead. They can absorb these increases more easily. Unsurprisingly, mortgage lending fell by more than 22% between 2022 and 2023, according to the latest official data from the National Statistics Institute (INE), and, again according to the INE, property purchases without a mortgage tripled in five years. This is linked to the boom in purchases by foreigners. They bought 15% of the homes on the market in 2023.
As regular readers of the Alveo Search blog know, buying property in Spain has many advantages for a foreign buyer.

Since the COVID-19 pandemic, a renovation fever has gripped homeowners, in Spain as elsewhere. Modernising, adding comfort and feeling good at home have become essential. In Spain, after growth of 3.2% in 2022, home renovation activity was expected to dip slightly in 2023, according to the National Association of Ceramics and Building Materials Distributors (Andimac). This dip is put down to an overall fall in consumption and higher interest rates, which slow home buying. Even so, once people take the step of buying a property, they always think about renovating it. As for tenants, they prefer homes they can picture themselves in, with a comfortable daily life. Landlords have understood this. The good news is that renovation work in Spain is not that expensive and that 25% of Spanish homes are over 40 years old. So it would be a shame to miss out. Here is our analysis.
In case you had any doubts, we can confirm it: renovation work in Spain is affordable. So if you are planning to renovate your new seaside home on the Costa Blanca, or your future flat-share investment in central Alicante, keep the following in mind:
One caveat: the COVID-19 pandemic, the war in Ukraine and inflation have hurt the renovation sector in Spain, as in the rest of Europe. Before the war with Russia, many building and renovation materials came from Ukraine (copper, aluminium, glass, etc.). When exports stopped, new suppliers had to be found, who were less competitive or raised their prices. Higher energy costs also feed through to the renovation market. Prices are therefore quite volatile today. That said, rest assured: buying materials in Spain is still cheaper, especially tiles and ceramics, which are made locally. The economic situation in Spain (with inflation at 3.5%) also keeps prices very competitive compared with other European countries. Finally, and this is good news, prices should fall as inflation slows.

Besides lower purchase and renovation prices, renovating in Spain has other benefits.
A full renovation is an investment. It always increases the value of the property. It is simple mechanics. The money you put in will come back to you and increase your capital gain when you sell. In Spanish it is called ganancia patrimonial, and we have written a practical guide on it, which you can read here. Also, renovated flats sell faster than those that need work. The idea of renovation can put off some buyers, who prefer to pay more for a home that is ready to move into.
Again, it is logical: when you renovate, you inevitably increase the rental potential of your property investment in Spain. It is even a key step to maximise rental returns.
Renovating in Spain is therefore a smart investment. For more advice or to discuss your project in detail, contact us: that is what we are here for.

For a few months now, a new trend has been sweeping through the Spanish property sector: house flipping or flipping inmobiliario (literally “turning a house over”). Alveo Search explains what it is and why this trend appeals to more and more buyers. The idea of house flipping is simple and already quite common in the United States: you buy a property in poor condition, renovate it and sell it again very quickly. The goal: maximise profits in record time. The trend has reached Spain because of the growing number of foreign buyers and strong demand for homes in city centres, where the housing stock is often outdated. But for the strategy to pay off, you need to choose the right property. On this point, you can rely on Alveo Search. It is our job. Our offices are on the ground and our advisers know the market inside out. They can pick properties and neighbourhoods with strong potential and negotiate good terms for you.

Renovating a property from top to bottom is generally cheaper (and much quicker, which helps) than taking on a building project. However, if the property needs major structural changes, it may be cheaper to knock it down and rebuild. To decide, it is important to consider, beyond the obvious costs, factors such as the property's sentimental value, its potential, the time you have for the project and so on. Every case is unique and must be assessed.
Since late 2021, some renovation work in Spain has qualified for support. As in other European countries, it is mainly projects that improve energy efficiency that are rewarded, chiefly under the Recovery, Transformation and Resilience Plan (PRTR). It is funded by NextGenerationEU, the EU's post-COVID-19 recovery plan, which focuses on investing in projects that support the green transition of member states. Here is what you need to know about the tax measures for IRPF (personal income tax) in Spain, which applies to Spanish tax residents. They cover work carried out until 31 December 2026 (31 December 2027 for the 60% deduction):
Obviously, there is no renovation without a clear and honest assessment of your budget. It is the key to a stress-free project.
As with buying property in Spain, owners have two options to pay for their works: from their own funds or with a loan. To answer a question our clients often ask: yes, mortgages from Spanish banks can include the cost of the works for renovating or improving a property. To include the cost of the works in a mortgage, the bank will usually assess the renovation project and the value of the property once the works are done. This may involve inspecting the property and a detailed estimate of the renovation costs. Keep in mind that:
One point to note: if you are not a Spanish tax resident, Spanish banks will be less generous with you. To find out more, see our article on mortgages: “How to get a mortgage in Spain: the complete guide”.

Elsewhere in Europe, the energy efficiency of homes has been hotly debated in recent months.
Before starting renovation work, it is important to understand what it involves in terms of regulations and to comply with local law. These rules vary in each of Spain's 17 autonomous communities, which makes the process a little complicated. But with the right support, there is no major problem ahead. The starting point is this: any change that affects the load-bearing structure of the building requires a licence or works permit. These authorisations are needed for extensions or additions, such as enlarging the building, including adding a room, a terrace or an extra floor.
We can only advise you to check with the local authorities and an architect for precise information on your specific case.
Prices vary depending on the licence you need and the municipality where the work, and therefore your application, takes place. The general rule is as follows: the cost of licences is between 3 and 4% of the overall budget. According to Idealista, the leading property portal in Spain and southern Europe, you should budget between €250 and €300 for most licences in Spain.
We will cover this briefly, but if you want to build a house, you should know that getting a permit takes a long time. Our guide “From buying the land to getting the keys: how to build a house in Spain” is available online and explains the whole process of building a property in Spain. In short, the municipality where your land is located will issue a building licence and oversee the whole project from a legal point of view. It sets the rules and limits on what you can and cannot do.
No renovation without careful planning. Improvising often leads to unexpected costs. Do not rush in, and do not take on a project out of proportion.
Before buying a property to renovate in Spain, it is crucial to assess it thoroughly.
Here are the priority works to consider to improve your property and increase its value, whether for your own use, for resale or for letting:

Timing matters, but it can vary greatly from one project to another. Allow a few weeks for minor work and up to six months for a large-scale project. As a rough guide, renovating a home of about 100 m² should take 3 to 4 months if the project runs without major setbacks.
If you plan to buy a seaside house to renovate and choose the wrong architect, the dream can quickly turn into a nightmare. This is even more true if you are buying from abroad and cannot visit the site regularly. In other words, caution is the watchword. Our tips for finding the right professional for your property:
Every renovation and every job, however small, needs to be monitored. Here, prevention is better than cure, as any mistake will cost you more. If you are abroad, hold regular check-ins with your architect. Do not hesitate to ask regularly for videos and photos of the work.

Renovating in Spain offers considerable advantages in terms of cost and ease of execution. It is also an effective option for foreign investors looking to maximise the return on their investment.
Yes, renovating in Spain may require different types of permit, including a building permit for structural changes or a minor works permit for simpler renovations. It is crucial to check the specific requirements with the local town hall before starting work.
To get a building permit, it is best to consult a local architect who can help you submit the plans and documents required to your local town hall.
Renovating without a permit can lead to heavy fines, an order to restore the property to its original state, or even legal action.
Tax deductions are available to Spanish tax residents for projects that improve energy efficiency.
Renovation costs in Spain vary widely depending on the region, the type of work and the quality of the materials chosen. On average, expect between €30,000 and €50,000 for a 100 m² property.
How long a renovation takes depends on the scale of the work. Minor projects can take a few weeks, while full renovations can last several months. In general, allow 3 to 4 months for a 100 m² home.
