Ibiza's rapid population growth has added substantial pressure to its housing market, while the island also faces a separate challenge in providing accommodation for thousands of seasonal workers who arrive each year.

The issue was highlighted by Ibiza Island Council's Territorial Councillor Mariano Juan during the presentation of the Balearic Islands Housing Observatory (OHIB), where new data showed that Ibiza's population grew by 82.74% between 2000 and 2025, while its housing stock increased by 39.56%.

The OHIB calculates a 43.18% housing deficit in relation to population growth over that period. This figure describes the gap between the growth of the population and the growth of the housing stock. It does not mean that 43.18% of Ibiza's homes are physically missing.

Population has grown much faster than the housing stock

The new OHIB figures provide a long-term picture of how Ibiza's residential pressure has developed.

Between 2000 and 2025:

• Population increased by 82.74%

• Housing stock increased by 39.56%

• OHIB's calculated deficit relative to population growth was 43.18%

Across the Balearic Islands as a whole, population increased by 46.34% during the same period, while the housing stock grew by 31.56%, producing a calculated housing deficit of 14.78%.

The difference is considerably larger on Ibiza and Formentera, where the OHIB calculates deficits of 43.18% and 54.36%, respectively. Mallorca's figure is 11.45% and Menorca's 8.39%.

The Observatory also records an 11% increase in the number of inhabitants per home in the Balearics between 2000 and 2025, another indicator of the pressure created when population growth outpaces housing growth.

The pressure is not only about residents

Mariano Juan argued that Ibiza's housing challenge needs to be considered in terms of different groups competing for accommodation.

During the OHIB presentation, he pointed specifically to seasonal workers as an additional challenge.

According to Juan, thousands of workers arrive on Ibiza each summer and require accommodation, creating demand at a time when the island's residential market is already under pressure.

He argued that seasonal workers need suitable accommodation without competing with residential housing intended for year-round residents.

The Consell has previously used an estimate of around 30,000 seasonal workers arriving on Ibiza each year. That figure is an institutional estimate cited by the Consell rather than a figure contained in the OHIB population and housing-stock indicator itself.

A changing seasonal-worker pattern

The issue is also more complicated than simply the number of people who arrive for the summer.

A draft diagnostic document for Ibiza's tourism intervention plan describes a change in the seasonal workforce, with a growing number of workers remaining on the island outside the traditional high season.

The document says the number of resident workers remaining during the fourth quarter increased by 25.9% between 2015 and 2024, equivalent to 4,353 additional resident affiliates. It also says foreign workers make up an increasing share of the resident workforce.

The document describes this as a shift from a strictly seasonal workforce towards a group that is increasingly present in Ibiza throughout the year.

That analysis is particularly relevant to housing because workers who remain on the island after the summer continue to require accommodation rather than leaving the residential market once the tourist season ends.

The Consell is looking at separate accommodation

The Consell has been developing proposals for accommodation specifically intended for seasonal workers.

Earlier this year, the institution said it wanted to identify specific areas through the Strategic PIAT where facilities for seasonal workers could be established.

The proposal is not for conventional residential apartments reserved for seasonal workers. The Consell has described the concept as accommodation with residential areas and shared facilities located close to tourist employment areas.

The objective is to provide workers with suitable accommodation while reducing the pressure placed on the ordinary residential rental market.

In July, the Consell said it was preparing a more concrete proposal and planned to discuss it with trade unions and business organisations.

The Consell also wants to increase permanent housing

Seasonal-worker accommodation is only one part of the Council's response to Ibiza's wider housing shortage.

During the OHIB presentation, Mariano Juan highlighted the Consell's role in making public land available even though the island institution does not have direct responsibility for housing policy.

One example is a site on Ibiza's seafront that has been transferred for the development of 25 homes intended for healthcare workers and teachers.

The project has a reported budget of €5.1 million.

Juan also said the Consell was negotiating the transfer of another site that could accommodate around 20 additional homes, although that second transfer had not yet been finalised at the time of his statement.

He also referred to efforts to address accommodation needs for other essential public-service workers, including Guardia Civil and National Police personnel.

More than 1,200 affordable homes are planned

The wider OHIB presentation also highlighted the Balearic Government's housing programme for Ibiza.

The Govern says more than 1,200 affordable homes are planned for residents on the island as part of its housing response. These are planned homes and should not be described as 1,200 homes already completed or available to move into.

This distinction is important given the difference between planning, construction and completed housing when assessing how quickly new supply can reach the market.

A housing challenge with several pressures

The latest data therefore points to several overlapping pressures rather than a single cause.

Ibiza's population has grown substantially faster than its housing stock over the past 25 years. At the same time, the island's tourism economy generates additional seasonal demand for accommodation, while a growing proportion of workers remain on the island beyond the traditional summer season.

The Consell's current response includes increasing the supply of permanent housing, making public land available for specific groups and developing separate accommodation models for seasonal workers.

The OHIB data provides the statistical picture, while the proposals from the Consell represent the policy response now being developed.

For Ibiza, the central challenge is not simply building more homes, but determining how much housing is needed, who needs it, what type of accommodation is appropriate and how additional supply can reach residents and workers at accessible prices.
