Ibiza's property market is showing signs of a slowdown in parts of the development sector, with architects reporting weaker investor appetite for new residential projects, fewer new-build apartments and continued delays in licensing and construction.

At the same time, property prices remain exceptionally high, creating a market in which new housing supply is becoming more difficult to deliver even as demand remains strong.

The latest figures and comments do not point to a broad collapse of the Ibiza property market. Instead, they indicate a more specific slowdown affecting certain forms of residential development and investment.

Architects Report Lower Investor Appetite

Lluís Oliva, president of the Ibiza and Formentera delegation of the Official College of Architects of the Balearic Islands, has reported a reduction in investor interest behind some residential developments on the island.

Speaking to Radio Ibiza, Oliva attributed the change partly to the length of time required to obtain licences and complete construction.

Long administrative procedures can make projects less attractive to investors looking for quicker returns. Construction can also take longer because of difficulties finding specialised workers, particularly for multi-family developments.

Oliva's comments concern capital behind residential developments rather than foreign buyers as a whole.

That distinction matters because international buyers continue to represent a substantial share of the Balearic housing market. In the second quarter of 2026, foreign buyers accounted for 32.27% of residential purchases in the Balearic Islands, according to the College of Registrars, compared with 15.98% nationally.

The available data therefore does not support describing the situation as a general departure of foreign buyers from Ibiza.

New Multi-Family Housing Falls

The clearest slowdown appears in private multi-family residential construction.

COAIB data for the first half of 2026 shows 376 newly created free-market multi-family homes in Ibiza and Formentera, down 26.85% from the comparable period.

The decline is particularly notable because multi-family projects are an important source of new housing supply on an island where available land is limited and demand remains high.

COAIB's figures also show that the wider number of newly created homes was broadly stable year on year when measured through June, with 805 new homes compared with 811 in the previous period.

However, the headline total needs to be interpreted carefully because extraordinary legalisation procedures have had a significant effect on the construction statistics.

Legalisations Distort the Headline Construction Figures

The number of construction files handled by architects increased substantially, but this does not mean that new construction increased by the same amount.

COAIB recorded 1,080 works in the Ibiza and Formentera area in the first half of 2026, an increase of 42.67% compared with the previous year.

Much of this increase was linked to extraordinary legalisations of existing buildings rather than the construction of new homes.

COAIB's data shows 805 newly created homes during the period, broadly unchanged from the previous year's 811. The organisation also identifies a substantial impact from the extraordinary legalisation process, particularly in the single-family category.

This is why the number of total works should not be interpreted as a comparable increase in new housing construction.

Prices Remain Extremely High

The slowdown in some development activity has not yet translated into a broad fall in property prices.

The Balearic Government's Housing Observatory puts the average effective transaction price in Ibiza at €5,611 per square metre in 2025, compared with €3,782 per square metre across the Balearic Islands.

For the municipality of Eivissa, the Observatory recorded an average transaction price of €5,112 per square metre in 2025.

Asking prices have risen further in 2026.

Idealista's August 2026 data puts the advertised price of homes in the municipality of Eivissa at €7,537 per square metre, 10.3% higher than a year earlier. The August figure was 0.9% below the July record of €7,606 per square metre.

These figures should not be confused with actual completed transaction prices. The Balearic Government has specifically warned that advertised prices are substantially higher than recorded sale prices. Its Housing Observatory found that property advertised on portals was more than 38% above the average actual transaction price across the islands in 2025.

Ibiza's Market Shows a Supply Problem

The combination of reduced private multi-family development and high prices highlights one of the central problems facing Ibiza's housing market.

Demand remains strong, but increasing supply is difficult.

The Balearic Government's Housing Observatory identifies limited land availability, demographic growth and restricted housing supply as structural factors contributing to pressure on the market. It also points to the effect of tourist use and sales to non-residents on the availability of residential housing.

The Government estimates that the Balearic Islands have accumulated a housing deficit of around 17,000 homes over the past 25 years. It has also announced plans involving more than 10,000 affordable homes at different stages of planning or development across the islands.

Some New Affordable Housing Is Appearing

The construction slowdown is not uniform across every category.

COAIB's first-half figures include 129 protected or price-limited homes in Ibiza and Formentera, after the sector had seen very little activity in this category for several years.

The Balearic Government is also advancing residential projects intended specifically to increase affordable housing for residents.

Among the planned Ibiza projects are 84 homes at Can Cantó, Mercat Pagès and Hort de sa Fruita.

These developments form part of a broader regional strategy intended to increase the supply of housing available to residents.

Foreign Buyers Remain an Important Part of the Market

The current figures do not support a simple narrative that foreign buyers are leaving Ibiza.

Foreign purchasers represented almost one-third of all residential purchases in the Balearic Islands during the second quarter of 2026, according to the Registrars.

Their share was 32.27%, a record-high proportion for the region in the Registrars' quarterly data, while the national figure was 15.98%.

The more specific concern raised by the Ibiza architects is the level of foreign and other investment capital available for residential development projects, particularly when long licensing procedures and construction delays reduce the attractiveness of those investments.

That is different from saying that international demand for existing homes has disappeared.

A Market at a Crossroads

Ibiza's property market is therefore presenting two apparently contradictory signals.

On one side, private multi-family new-build activity has fallen significantly, and architects say some investors are becoming less willing to commit capital to projects that can take years to obtain permits and complete.

On the other, demand remains substantial and property prices remain at very high levels.

The result is a market where the cost of housing can continue rising even while the pipeline of some types of new housing weakens.

The next series of construction permits and housing transactions will be important in determining whether the decline in private multi-family development becomes a longer-term trend or represents an adjustment following several years of strong investment activity.

Ibiza One Stop Accuracy Note

The evidence supports describing parts of Ibiza's property development market as showing signs of cooling, particularly private multi-family new construction.

It does not support saying that Ibiza's entire property market is collapsing or that foreign buyers are broadly abandoning the island.

COAIB recorded 376 free-market multi-family homes in Ibiza and Formentera in the first half of 2026, down 26.85% year on year. At the same time, the Registrars reported that foreign buyers accounted for 32.27% of Balearic home purchases in Q2 2026, a record-high regional share in that dataset.

The €5,611 per-square-metre figure is the Balearic Government's 2025 average effective transaction price for Ibiza, while the €7,537 figure is an August 2026 advertised price for the municipality of Eivissa. They measure different things and should not be presented as directly equivalent.
