In Spain, the word “okupa” refers to the illegal occupation of a home by a third party. Owners are wary of it for several reasons: okupas can disturb the neighbours, damage the property and, worse still, create complex legal problems. Faced with this threat, it is essential to take preventive measures and find ways to protect your property.
In this complete guide, Alveo Search shows you the most effective ways to secure your house or flat against okupas. We also share our expert advice on preventing the illegal occupation of your property, whether you are a resident or a non-resident. In this article, you will see the areas of Spain most affected, the types of property most at risk, and the costs to plan for when putting security measures in place.
An “okupa” is anyone who deliberately moves into a property illegally. The property may be a lived-in home or an abandoned building. Squatters count as okupas as soon as they occupy the premises without the owner's consent. Although the phenomenon has existed for decades, it is becoming more and more common in Spain. In 2017, the Institut Cerdà reported 87,000 okupas in Spain. The most common causes are the economic crisis, the lack of affordable housing and the growing number of empty buildings.
Okupas can get into a property by forcing doors or exploiting security weaknesses. Some owners even call them “home snatchers”. Once inside, they often change the fittings and live there without paying rent, which can have serious legal and financial consequences for owners.

Owners are wary of okupas because the consequences can be serious. First, they lose control of their property, and it is often impossible to put things right without going through more or less complex legal steps. Very often, okupas refuse to leave, which makes it hard to recover the property.
Yet in Spain, legal fees are high and it can take several months to obtain a favourable ruling. Okupas also do not look after the property, so it can suffer physical damage. And if the owner plans to sell, this damage can lower its market value.
Spanish law above all protects the occupants of a property, at least for a limited time. This makes evicting okupas harder: once settled, they are treated like ordinary residents, with legal protections that let them stay in the home for several months, or even several years.
This is why some owners hit by okupas end up in a difficult situation, waiting months before they can recover their property and carry out their own plans. In general, they have to turn to the competent authorities or to specialist services.

In 2024, Spain is one of the countries most affected by the illegal occupation of homes. According to the latest statistics, nearly 10,000 cases of illegal occupation were recorded last year, with an upward trend in some regions, especially in large cities such as Barcelona, Madrid and Valencia.
Faced with this situation, the Spanish government has introduced several laws to make evicting okupas easier. Even so, owners are left waiting, because the process remains slow and complex: they have to wait about 2 years or more for an outcome. Fortunately for them, autonomous communities such as Madrid have taken the initiative to tackle the problem with their own means. However, only national law can make the final decisions.
The main victims of okupas in Spain are private owners with empty homes. However, banks and some financial institutions suffer the same fate, as they generally hold a large number of properties. For banks and private owners alike, the impact can be devastating, both financially and personally.
Okupas mainly target Spain's urban areas, notably Madrid, Barcelona, Valencia, and Seville. These cities attract okupas because of a number of features:
The most vulnerable districts are in Madrid and Barcelona, including Eixample, Gràcia, Lavapiés and Tetuán. These are very dense areas where many buildings are old, which makes them an obvious opportunity for okupas. They also know that this type of property is easier to break into.
Outlying districts, for their part, are less closely watched and have empty homes almost everywhere. For example, the Spanish capital has seen a rise in illegal occupation in its suburbs. There are also districts where property is cheaper, both to buy and to rent.

Okupas looking for temporary housing are very interested in regions with many tourists. The areas concerned are mainly the Canary Islands, the Balearic Islands and Mediterranean coastal areas such as the Costa Brava and the Costa del Sol. Empty properties there are often second homes, and some owners prefer to let them as holiday rentals.
Holiday homes and flats for rent are therefore particularly vulnerable, as they often stay empty for long periods. Okupas take advantage above all of the off-season.
Some okupas take advantage of abandoned or rarely used properties in rural areas. Inland regions such as Castilla-La Mancha or Andalusia, although less populated, often face illegal occupation. These areas have fewer people, but the risk is real when properties are left abandoned or poorly secured.
Okupas prefer empty flats, especially those waiting to be sold or let. This type of property is common in Spain, where some homes stay empty for months or even years. They also target the least secure homes in outlying districts, which are easy to get into: sometimes windows are broken or doors are simply not locked.
Second homes are also common targets. These properties are used now and then, rarely watched, and therefore easier to break into. Very often, the owners do not live in Spain and only come for holidays. When a house is left empty for a long time, it is an easy opportunity for okupas, especially in a tourist area.
Abandoned commercial or industrial buildings are also often in areas that are poorly watched, or not watched at all, and local authorities take little interest in them. This makes them prime targets for okupas. These properties are usually quite large and easy to turn into temporary housing. For example, factories or shops closed for a long time are easy to occupy discreetly.
Banks hold properties recovered through repossessions. These homes are empty and often stay that way for a long time. People without housing see an opportunity to live there until the bank decides to sell or renovate. Banks are also slower to act because of complex administrative procedures, and okupas know how to take advantage of this.

To prevent illegal occupation effectively, the first step is to secure your property properly, with measures that range from simple to more involved.
Alarm systems and video surveillance have become essential tools to protect a property against any kind of intrusion. There are many types of alarm, and the most modern can be connected to monitoring centres that react immediately to any attempt.
If you choose CCTV cameras, install them at the main access points of the property so that you can keep the home under constant watch.
If you own a home in Spain, it is strongly advised to use it regularly or to make sure a trusted person visits it as often as possible. This way you avoid attracting okupas. If you do not live in the country, consider hiring a caretaker and setting up a concierge service.

Recovering an illegally occupied property can be very complicated. To avoid getting caught out, prepare your documents in advance and keep them close to hand. They are essential to prove that you own the property and to make any legal procedure easier if okupas move in.
As soon as you find that someone has taken over your property without your consent, act quickly. Here are the key steps to follow in an emergency:
Fortunately for owners in Spain, there are now specific contracts and insurance policies designed to protect against okupas.
In most cases, private security companies are the most effective way to keep a property safe. They can provide a range of services, including:
Concierge services include regular checks on your property, upkeep and repairs, and sometimes measures to prevent illegal occupation. The aim is to maintain and check your property regularly, which keeps okupas away.
If you own a home in Spain but cannot be there, you will need remote surveillance. Popular devices such as connected cameras let you watch your property in real time from anywhere in the world through a mobile app. As soon as the camera detects suspicious movement or unauthorised access, it sends an alert to your phone.
If you own a house or flat in Spain but do not live there, managing it can be a heavy task. And if the property is rarely used, okupas are more likely to take advantage of it. Our experts recommend these effective strategies to reduce the risk:
To secure your property in Spain effectively, you can also join local neighbourhood watch networks or residents' committees. Nearby owners can then support each other in keeping an eye on their properties, especially when they are away. In Spain, groups of neighbours get together to report any suspicious activity and keep each other informed of break-in risks in the area.
These networks may, for example, organise joint security patrols or recommend security providers. Members share information through private channels. Non-resident owners can join these networks by signing up on local online platforms.
As technology advances, surveillance systems are getting better too. Many new solutions can be used to protect a property against okupas. Here are some of the most effective options:
When you are away, monitoring apps help you manage the security of your property remotely. For example, some platforms let you connect all your security systems (cameras, alarms, sensors) to a single app.
Cost is always a major concern for owners. You can choose between different levels of protection, and prices vary with their scope and effectiveness.
Here is an estimate of the main investments:

Even if these solutions are a significant investment, they pay off in the long run. Protecting a property against okupas can avoid much higher costs. When you compare the cost of security systems, insurance and professional services with the risks of illegal occupation, the balance is clearly favourable.
Several owners' associations in Spain offer advice, resources and support in cases of illegal occupation. They defend owners' rights and can provide useful information on legal procedures. Search online to see whether there is one in your area.
Many lawyers specialising in Spanish property law can guide you through the legal procedures linked to illegal occupation. Contact a lawyer as soon as possible to assess your options and put an effective strategy in place.
Here are some of these services (the UK government's “Find a lawyer abroad” service also lists English-speaking lawyers in Spain):
Local authorities, such as the National Police or the Guardia Civil, are the first to respond to an illegal intrusion.
Here are some emergency numbers to know:
National Police (Policía Nacional): 091
Guardia Civil and emergencies: 062, 112
Guardia Civil headquarters: Calle Guzmán el Bueno 110, 28003 Madrid
Phone: +34 915 146 000
Email: dg-registrocentral@guardiacivil.org
Important: It is advisable to call 091 for the National Police or 062 for the Guardia Civil in case of illegal intrusion. For situations that need immediate assistance or other emergency services, 112 is also available.
If you own property in Spain, protecting it against okupas is essential. This takes a proactive approach that combines legal, technical and security solutions. By putting the right security measures in place, surrounding yourself with qualified professionals and knowing your rights, you can minimise the risk of illegal occupation. Prevention is essential, and if okupas do get in, act quickly.
