Housing and tourism in Spain: what the data say

Two things are true at once: Spain lacks homes where people want to live, and tourism is one of the main engines of its economy. The public debate is often reduced to "tourists versus residents". This article takes no side: it gathers the data available as of 5 October 2026, explains how the pieces connect and is honest about what we still do not know.

The picture in one minute

• Housing shortfall: the Bank of Spain estimates that a shortfall of about 750,000 homes built up between 2021 and 2025. In 2025 alone, around 240,000 households were formed while about 92,000 homes were completed.
• Tourism: 2025 closed with 96.8 million international tourists (+3.2%) and spending of €134,712 million (+6.8%), according to INE.
• Tourist flats: in May 2026 there were 341,001 homes advertised on digital platforms, 10.7% fewer than a year earlier. That is roughly 1.3% of the 26.6 million homes counted in the 2021 Census.
• Weight of tourism: according to the OECD, it accounts for 13.4% of employment, 6.0% of GDP (direct effect) and 48.4% of services exports.
• Social housing: around 2.5–3% of the total stock, versus roughly 9% on average in the EU.

The underlying problem: not enough homes where they are needed

Think of musical chairs: eleven players, ten chairs. However the seats are shared out, someone is left standing. The rules only decide who; to leave nobody standing you have to add chairs.

Housing in Spain works a bit like that. In 2025 about 240,000 new households were formed and about 92,000 homes were completed. That gap, repeated year after year, is what the Bank of Spain sums up as an accumulated shortfall of around 750,000 homes, which could keep growing in the coming years.

The shortfall is not spread evenly. According to the Bank of Spain, half of it is concentrated in six provinces: Madrid, Barcelona, Alicante, Valencia, Murcia and Málaga. In other words, Spain does not simply have "too few homes" but too few where people want and are able to work and live.

The most frequently cited causes are a lack of developable land, rising construction costs, slow permitting and a small social housing stock (around 2.5–3% of the total, against roughly 9% on average in Europe).

What role do tourist flats play?

There are two opposite mistakes worth avoiding:

• "They are irrelevant." They are not, in many neighbourhoods and municipalities.
• "They explain the whole crisis." Nor that: at national level they are only one part of the problem.

One way to see it: a spoonful of salt is barely noticeable in a big pot, but in a glass of water it changes everything. The national 1.3% says little about what happens in a specific neighbourhood. INE's experimental statistics show where the advertised homes are concentrated (May 2026):

By municipality, the list is led by Madrid (10,836), Málaga (8,288), Barcelona (8,231), Marbella (6,987) and Seville (6,937).

What does the evidence say about the effect on prices?

• Fedea reviewed 429 international studies. Its conclusion: the clearest and best-documented effect is on housing, because the supply of long-term residential rentals shrinks and purchase and rental prices rise, especially where tourist pressure is highest. It also acknowledges that these rentals spread tourist spending to areas without hotels.
• Barcelona is the most studied case. A paper in the Journal of Urban Economics (García-López and others, 2020) estimated that, in the average neighbourhood, Airbnb activity raised rents by 1.9% and transaction prices by 4.6%. In the 10% of neighbourhoods with the most activity, by 7% and 17% respectively.

Simple reading: the effect exists, it is moderate on average and large in the most saturated areas. That is why the debate depends as much on "where" as on "how much".

The other side of the scale: tourism also supports the economy

Tourism is not a marginal activity. When a visitor rents accommodation, they also spend on restaurants, shops, transport, excursions and leisure, which translates into jobs, social-security contributions and taxes. The data help size it:

• A little over 13% of the country's employment depends directly on tourism (around three million people).
• Travel accounts for almost half of services exports: when a foreign visitor spends money in Spain, the country "exports" tourism services.
• International tourist spending exceeded €134,000 million in 2025 and kept growing in the first half of 2026 (€63,800 million, 7% more).

One important nuance: more tourism does not automatically mean more public housing. The taxes it generates go into the general budget, and where they go is decided by public budgets: pensions, healthcare, education, infrastructure, housing… The link is indirect.

Tourism also has local costs that do not show up in GDP: noise, congestion, neighbourhood shops replaced by businesses aimed at visitors, higher turnover of residents. The studies reviewed by Fedea describe them. There are costs and benefits on both sides.

If tourist flats are restricted: three open questions

Regulating an activity that imposes costs on third parties (for example, neighbours who cannot find a home) has a well-known economic logic, and regulating is not the same as eliminating a sector. The real discussion is how and with what side effects. There are three questions on which the data do not yet give a closed answer.

1. Where do the homes that stop being tourist rentals go?

A home leaving the tourist market can end up in several places:

• Long-term residential rental: the outcome that restrictions aim for.
• Seasonal rental: does little for the underlying problem.
• Sale: to a resident, an investor or a company.
• Other uses, or left empty.
• Hotel or aparthotel, if viable.

The Bank of Spain has already noted that alternative uses (tourist, room rentals and seasonal lets) limit the growth of residential rental supply. So counting how many tourist flats disappear is not enough: what matters is how many homes actually end up as residential rentals.

New York, which tightened its rules in 2023, is a warning that design matters. According to the available analyses — some commissioned by the industry itself, so they should be read with caution — listings fell by around 90%, but rents kept rising and hotels became more expensive. Barcelona will run its own experiment: it will not renew its roughly 10,000 licences from November 2028. There are no results yet.

2. Do tourists leave if accommodation gets more expensive?

A simple example: a British family has €2,500 for its holiday and compares Spain, Greece, Türkiye and Portugal. If Spain's total cost rises sharply while the others stay the same, some families will choose another destination.

CaixaBank Research has tried to measure this. It estimates that international tourist demand for Spain has a price elasticity of roughly −1.87: a 1% rise in prices is associated with an approximately 1.87% fall in arrivals. And a cross-elasticity of 1.14: if competing destinations become 1% more expensive, arrivals in Spain rise by 1.14%.

Two caveats. It is an average estimate, based on prices in general, not on the price of accommodation or of any specific type of offer. And what happens in practice depends on how much prices really rise and how much hotels can absorb.

Recent data show no drop so far:

• In 2025, tourists staying in rented homes fell by 9.3% and those staying in hotels rose by 7.3%, while the total grew by 3.2%.
• In the first eight months of 2026 about 70.4 million tourists arrived (+5.4%), and 12.3 million in August (+9.2%).

This can be read two ways. One: hotels are absorbing the demand leaving tourist rentals. The other: the strongest restrictions are only just starting and their effect on prices may take time to show. Current data are not enough to rule either out.

3. What happens to investment and construction?

A developer decides whether to build based on the cost of land and materials, financing, timelines and the price they expect to get. Rules that change quickly add uncertainty, and uncertainty is a cost.

• Argument of those who fear restrictions: if expected returns fall or risk rises, some projects do not go ahead and, years later, the result is fewer new homes.
• Argument of those who defend them: clear, stable rules also provide certainty, and the effects they seek (recovering existing housing) arrive sooner than those of building.

Both hypotheses are reasonable. We have not found a conclusive estimate for Spain, which is why effects need to be looked at over 5–10 years, not only 12 months: a measure can help in 2027 and weigh in 2032, or the other way round.

This week's news: the decree that did not survive

On 29 September, Royal Decree-Law 26/2026 (urgent measures for the social function of housing) was approved. Among other things, it set a 10% VAT for certain tourist homes and allowed town councils to apply IBI property-tax surcharges of 50%, 100% or 150% in stressed housing areas, depending on the number of tourist homes the owner holds.

On 2 October the Congress voted on whether to validate it: it received 172 votes in favour and 178 against, so the decree was repealed after being in force for little more than a day. A second decree, on rental contracts, met the same fate (166 in favour, 184 against).

What does that mean in practice? That those specific state measures do not apply. The rest of the framework does not disappear:

• The single rental registry, mandatory since 1 July 2025. In 2025, the Ministry of Consumer Affairs got Airbnb to remove more than 65,000 listings deemed illegal.
• Regional and local rules: Barcelona's plan not to renew its licences in 2028 (backed by the Constitutional Court in 2025), or the Catalan tourist-tax increase from April 2026, with 25% of the revenue earmarked for housing policies.

We do not judge whether the outcome is good or bad. We record it because it changes the starting point, and because the underlying debate remains open.

A map of tools (recommending none)

These are the most debated measures, with their possible advantages and drawbacks. It is not a recommendation: which combination to choose and at what pace is a political decision.

Alicante: why one recipe does not fit everywhere

In the province of Alicante almost all the pieces come together: population growth, a strong presence of foreign residents, second homes, international tourism and tourist rentals. The Bank of Spain includes it among the six provinces that concentrate half of the shortfall, and the Valencian Community had 51,268 tourist homes advertised in May 2026.

A highly stressed coastal city and an inland village with little demand do not have the same problem. That is why one of the most debated ideas is to tailor measures by zone rather than apply them identically everywhere. Which zones and by what criteria is, once again, the hard part.

What we know and what we do not

What the data support

• The housing shortage is structural: far fewer homes are built than households are formed, especially in a few provinces.
• Tourist flats are a small part of the national stock but highly concentrated, and in those areas there is evidence that they put pressure on prices.
• Tourism is a first-order economic pillar in jobs, exports and tax revenue.
• The social housing stock is small compared with the European one.

What we still do not know

• How many homes leaving tourist rental actually end up as residential rentals.
• How much tourist demand would be lost (if any) because of more expensive accommodation, and how much hotels would absorb.
• How rule changes affect construction in the medium term.
• What the net balance in jobs, tax revenue and access to housing is for each combination of measures.

How to tell in 2030 whether a policy has worked

Counting the tourist flats removed is not enough. To really assess any combination of measures you would need to look at all of these at once:

1. How many new homes have been completed.
2. How many residential rental homes exist and how much rents have risen.
3. How much the price of tourist accommodation has changed.
4. How many tourists arrive and how much each one spends.
5. How much tourism employment there is.
6. How much real estate investment and construction there is.
7. How much the public housing stock has really grown.

Only with all these indicators together can we tell whether a policy has improved the whole picture and not just one piece.

If you own (or plan to buy) a home in Spain

Whatever your view of the debate, there are three practical points:

• Rules change fast and vary by region and municipality: this very week has shown it. Before renting out your home, check the regional and local rules currently in force.
• Tourist and seasonal rentals need the single-registry number, in addition to any licences each territory requires.
• If you do not live in Spain and rent out your home, that income is taxed in Spain and declared with Modelo 210; there is also imputed income for homes that are not rented out. You can read more in our guides on rental income tax and what Modelo 210 is.
