Spain is facing a significant housing challenge, with an estimated shortage of 750,000 homes nationwide, according to the Bank of Spain's 2025 annual economic report. The warning highlights growing concerns over the country's ability to meet rising housing demand, particularly in major urban centers where population growth continues to outpace residential construction.
The report identifies Madrid, Barcelona, Alicante, Valencia, Murcia, and Málaga as the provinces most affected by the imbalance between housing supply and newly formed households. Together, these six provinces account for more than half of Spain's housing deficit, with their capital cities home to approximately 36% of the country's households.
According to the Bank of Spain, residential construction has failed to keep pace with demand in recent years, creating mounting pressure on housing affordability and availability. The institution estimates that around 750,000 additional homes would be required to bridge the gap between available housing stock and the number of households seeking accommodation.
The shortage varies considerably across regions. While some provinces retain significant unused housing capacity, major metropolitan areas face severe constraints. Madrid has one of the lowest levels of available residential stock that could be brought to market, significantly below the national average. Similar pressures are being experienced in Barcelona, Alicante, Valencia, Murcia, and Málaga, where housing demand remains particularly strong.
The report also points to the growing impact of tourist and short-term rental properties. Approximately 400,000 homes across Spain are currently used for tourism-related accommodation or as second residences for domestic and international owners. Between 2021 and 2025, non-resident buyers purchased an average of 50,000 homes annually, representing 7.4% of total residential transactions. The Mediterranean coast has been especially affected by this trend.
At the same time, Spain faces a contrasting challenge: nearly 450,000 vacant homes remain unused across the country. Many of these properties were built during the housing boom of the early 2000s but remain unoccupied due to unsuitable locations, deteriorating conditions, or limited access to essential services.
The Bank of Spain notes that the country's housing shortage is among the most pronounced in Europe. Spain and Portugal have experienced some of the largest gaps between housing construction and household growth, with Spain's deficit reaching 6.6% of its existing housing stock. Portugal faces a shortage of approximately 300,000 homes, while Italy's housing gap is estimated at around 400,000 units. Germany remains the only major eurozone economy to have reduced its housing deficit in recent years.
Industry experts attribute Spain's housing bottleneck to a combination of regulatory and structural challenges. Lengthy planning approvals, overlapping regulations across local, regional, and national authorities, labor shortages in the construction sector, and declining productivity have all contributed to slower housing development.
Despite these obstacles, the report suggests significant untapped construction potential. Across Spain's six largest urban areas, enough land and planning capacity exist for approximately 1.1 million homes. However, only around 320,000 planned housing units are currently concentrated within the capitals of those metropolitan regions, limiting the immediate impact on the areas experiencing the greatest demand.
As housing affordability continues to dominate public debate, policymakers face increasing pressure to accelerate construction, streamline regulations, and expand housing supply in order to address one of Spain's most pressing economic and social challenges.
