Why opt for renovation in Spain?
- Real estate renovation in Spain offers many significant advantages, including a substantial increase in the property value, with an average increase in the sale price of more than 30% for renovated apartments.
- It also allows to preserve the unique character and charm of old Spanish properties while modernizing them.
- But also to improve the energy efficiency of the property, a key aspect in Spain where the construction sector represents 31.6% of the country's final energy consumption. We will come back to this.
- Renovated apartments sell faster than others. Buyers prefer turnkey properties. Some seasoned investors, aware of the opportunities in the Spanish market, are even turning to express buy-sell to maximize the return on their investment in record time.
- Last advantage: it is cheaper than in France.
What is the cost of labor for a real estate renovation in Spain?
One of the main advantages of real estate renovation in Spain lies in the cost of labor, which is significantly lower than that in France. On average, the hourly cost of labor in Spain is €25 excluding VAT, compared to a range of €35 to €65 excluding VAT in France. This difference allows for substantial savings on the overall project budget.
What is the price of construction work in Spain?
- The average cost of a renovation in Spain is around €28,000, a figure which is also lower than the French average (€60,000 for a standard renovation).
- For a property with a surface area of 100 m², the renovation budget is generally between €30,000 and €50,000, a boon for investors.
- The price per square meter generally ranges from €400 to €900 per square meter, depending on the scale and nature of the project.
- Please note that in recent years, quotes have increased by more than 20%.
What is the price of construction materials in Spain?
Recently, in Spain, the prices of materials have increased, due to the pandemic and inflation. In February 2024, the construction cost index reached a record level, the highest since records began in 2005. Although the upward trend stabilized somewhat in 2023, prices remain significantly higher than pre-pandemic levels.
The materials most impacted are:
- Ceramics (+52% in the last 10 years)
- Cement (+49%)
- Aluminum (+48%)
- Wood (+32%)
- Glass (+31%)
Despite these increases, materials remain cheaper on the other side of the border.
Real estate renovation increases the rental potential of a property
In Spain, a country where the seasonal rental market and student co-living are particularly dynamic, a renovated property can see its rental potential and return significantly improved.
A tenant will, in fact, be quite willing to pay a higher rent if the quality of services and comfort are up to par. Furthermore, tenants willing to pay a rent slightly higher than the average are generally reliable tenants who take care of their accommodation. An advantage for the owner and guaranteed savings.

The context of the real estate renovation market in Spain
Renovation in Spain, a booming sector
Since the 2020 pandemic, the real estate renovation sector in Spain has been booming. Why?
- Because successive lockdowns have made us realize that it is important to feel good at home.
- Because improving the energy efficiency of homes has become necessary and unavoidable.
- Because foreigners, whose purchasing power is often greater than that of Spanish buyers, bought more than 15% of the available properties in 2023 and did not hesitate to carry out work.
- Because tourist rentals have exploded, and with them, the need to carry out work to satisfy travelers.
The most common types of real estate renovation in Spain
Real estate renovation projects in Spain cover a wide range of works, including:
- The modernization of kitchens and bathrooms, which is very popular for increasing the rental value of properties.
- That of the bedrooms, when the apartment is intended for student co-living.

Regulations, licenses and building permits in Spain
An essential point to keep in mind: never embark on a real estate renovation project in Spain without consulting your co-ownership and without contacting an architect. You would be taking a big risk.
What are the local regulations for real estate renovations in Spain?
In Spain, each locality and municipality has its own regulations regarding renovation work. For example:
- Catalonia: in Barcelona, strict rules govern the conservation of architectural heritage. Renovations often require specific permits, and technical inspections are mandatory for old buildings. The regulations aim to preserve the historical architecture and guarantee the sustainability of constructions.
- Andalusia: on the other hand, in Andalusia, the rules may be more flexible. Minor renovations may require fewer administrative formalities, and the deadlines for obtaining permits are often shorter, which promotes a faster renovation process.
Before embarking on a renovation project, our experts inquire about the specific regulations of the autonomous community concerned. Get in touch with them.
What are the different building permits in Spain?
Two main types of permits are required for renovation work in Spain:
- Licencia de Obra Menor: for minor works that do not modify the structure of the building. Please note that once issued, this permit is only valid for 3 months;
- Licencia de Obra Mayor: for major renovations affecting the structure or exterior appearance of the building and which require the presentation of detailed plans drawn up by an approved architect.
How much do building permits cost in Spain?
- It is generally estimated that the price of a building permit in Spain is less than 300 euros, i.e. 3 to 3.5% of the estimated amount of the work.
- File processing fees are added, varying according to the municipalities.
What are the procedures for obtaining building permits in Spain?
- The permit application is made to the town hall (ayuntamiento) and upon presentation of a Proyecto de Reforma (the renovation project) signed by an architect for significant renovations.
- The time to obtain a permit varies from 1 to 3 months for the Licencia de Obra Menor and can extend to 6-8 months for the Licencia de Obra Mayor. However, this depends on the complexity of the project and the municipality.
What are the risks of carrying out renovation work without a permit?
If you do not follow the procedures, you risk paying a fine (from 600 to 1000 euros for small jobs) or forced demolition.
Furthermore, it is important to note that undeclared work can lead to difficulties when reselling the property (complicated transaction, drop in property value). In other words: do not try to circumvent the rules. You will pay dearly for it.

Energy renovation in Spain
Where does Spain stand on energy renovation?
Did you know that 80% of homes in Spain do not meet the European Union's strict energy standards? Following the new legislation in force, by 2033, all homes sold or rented must achieve a minimum energy certificate of class D. Faced with this challenge, energy renovation is not only becoming a necessity, but also a promising investment opportunity.
When planning your renovation, make sure your project complies with the new regulations. This may include:
- Thermal insulation of walls, roofs and windows
- The installation of energy-efficient heating and air conditioning systems.
- The use of sustainable and ecological materials.

- An average property revaluation of around 30%, as we said above.
