A paused housing stock
The urban and rural landscape of Alentejo is marked by a silent contrast: the number of housing units exceeds, in many municipalities, the actual demand of resident families, yet the housing crisis worsens. According to the 2021 Census by Statistics Portugal (INE), Portugal recorded 723,215 vacant or unoccupied housing units, representing 12.1% of the national housing stock. In Alentejo, this phenomenon is not new, but its persistence in municipalities with severe social needs paints a picture of structural inefficiency.
Historically, Alentejo has already demonstrated this misalignment. INE data from 2001 reveals that, in the 1990s and 2001, the region recorded growth in housing units between 5% and 10%, clearly out of step with demographic decline and the decrease in the number of families, particularly in Alto Alentejo. This trend, which has dragged on for over two decades, has consolidated a housing stock that, although numerically vast, does not meet the contemporary needs of those looking for a home.
Today, the situation is exacerbated by an imbalance between supply and demographics. According to a Bank of Portugal study released in late 2025, the deficit in the creation of new housing supply went from an average of four thousand families per year between 2011 and 2021 to about 14 thousand families per year after 2021. This growing gap puts unprecedented pressure on a regional market that, despite having houses, fails to make them available at affordable prices.
Age and deterioration as a barrier
The quality of the built environment is the first major obstacle to occupation. Alto Alentejo stands out, according to the final data from the 2001/2021 INE Census, as the sub-region (NUTS III) with the oldest housing stock in the country, registering a building aging index of 2,571. This value, which reflects the age and degradation of the structures, is accompanied by Baixo Alentejo, with 2,213, and Central Alentejo, with 2,200, highlighting the structural obsolescence that characterizes the region.
This degradation is not just aesthetic; it is functional. In a report by Correio Alentejo from 2026, it was emphasized that hundreds of homes, in both rural and urban areas, lack elementary thermal conditions, featuring damaged roofs and degraded window frames. These deficiencies inhibit permanent occupation, turning houses that could be homes into structures that require rehabilitation investments which often exceed the financial capacity of owners or potential tenants.
The impact of this degradation is visible in the difficulty of placing these homes on the market. While Observador, in a 2023 analysis, noted that the lack of supply coexists with the severe degradation of urban centers, IHRU, based on the 2021 Census, found that out of the 485,461 empty houses in good habitable conditions in Portugal, only 236,927 were actually on the market for sale or rent. In Alentejo, the proportion of houses that do not meet minimum habitability requirements is a determining factor for the scarcity of real supply.
The myth of excess supply
The most obvious reading given high numbers of empty houses would be that Alentejo has a supply surplus that should, theoretically, lower prices. However, the reality of the real estate market in 2026 disproves this perspective. According to Rádio Pax, citing idealista data, housing prices in the region registered a year-on-year increase of 19.2%, the second highest growth rate nationwide, proving that the physical existence of buildings does not translate into economic availability.
What explains this mismatch? Most empty houses are off the market due to a tangle of factors: undivided inheritances, legal disputes, prolonged abandonment, or advanced ruin. This is not a choice of withholding supply, but a legal and financial inability to put these properties at the service of the population. While Beja's real estate market, for example, appreciates by 21.9% per year, many of these houses remain closed, incapable of easing pressure on prices.
Even in municipalities where the market is not boiling, supply is not affordable. Data from early 2026 indicates that municipalities like Borba and Portel registered year-on-year drops of -5.3% in median transaction values, settling at €875/m² and €758/m² respectively. Even so, these drops do not solve the problem of families with severe resettlement needs, which, according to IHRU data from 2020 released by Diário do Alentejo, amounted to 1,028 families in the region, with critical situations concentrated in Beja, Moura, and Sines.
The role of the State and the future
The scarcity of public housing is another factor aggravating the crisis. According to the balance sheet of the European Parliament's Housing Committee (HOUS) following an official visit to Portugal in 2026, the proportion of public housing stock hovers around just 2% of the total, ranking among the lowest in the European Union. This fragility limits the State's response capacity to the needs of the most vulnerable families, who depend on an increasingly inaccessible private market.
To try to reverse this scenario, the Alentejo Coordination and Regional Development Commission (CCDR) launched the 'Alentejo 2030' program. With an allocation of 15.4 million euros in European funds (ERDF and Just Transition Fund), the program aims to support the construction and rehabilitation of social housing through Local Housing Strategies, as announced in 2026. The objective is clear: to try to recover degraded buildings and create new solutions where the private market fails.
The effectiveness of these measures will depend on the speed with which these funds reach the ground and the ability of local authorities to manage complex rehabilitation processes. With the average household size decreasing, as Pordata points out in 2026, the need for smaller, more efficient homes becomes pressing. The challenge for the coming years will therefore be to transform existing built heritage, often in ruins, into dignified and affordable housing for a population that, although smaller in number, has more fragmented and urgent housing needs.
The impact on family life
For those living in one of Alentejo's 47 municipalities, these numbers translate into a daily routine of uncertainty. The coexistence of closed houses with the difficulty of finding fairly priced rentals creates palpable social frustration. When a young person in Beja or a family in Moura looks for a home, they face not only a lack of new construction, but a structural roadblock where existing buildings are, in practice, unavailable or uninhabitable.
Reliance on funds like those from 'Alentejo 2030', with its 15.4 million euros, underlines that the solution to housing in Alentejo will not come solely from the market, but from direct public intervention in rehabilitation. Without this capital injection and without a strategy that resolves the legal hurdles of inheritances and degradation, the housing stock will continue to be a museum of empty houses, while families continue to face the housing crisis.
The future of housing in the region will be defined by the ability to convert what is idle into something useful. If, in 2026, the gap between family growth and housing supply remains a structural problem, the response will have to be as complex as the problem itself. Alentejo does not just need more houses; it needs to unlock the ones that already exist, ensuring that the aging of buildings does not condemn future generations to an access crisis that has dragged on since the beginning of the century.
