The real estate market along the Castellón coastline is experiencing strong growth, with coastal municipalities accounting for half of all home purchases in the province during 2025. At the same time, new construction activity has increased significantly, highlighting the strength of demand in this area. Today, from Quinta Avenida Inmobiliaria, we explain how the property market on the Castellón coast is evolving, which locations stand out and what is driving this growth.
The Castellón coast concentrates 50% of home purchases
Coastal municipalities in Castellón, excluding the provincial capital, accounted for 50% of all home sales in the province during 2025.
A total of 7,648 transactions were recorded along the coast, representing a 2.6% increase compared with the previous year. Across the entire province, transactions reached 15,341, an 8% increase.
These figures demonstrate the growing importance of coastal areas within Castellón’s real estate market.
New development activity increases by 125.8%
One of the most significant figures is the sharp increase in new development activity.
New permits for new-build homes on the coastline increased by 125.8% in 2025, reaching 788 of the 1,738 permits issued across the province. Coastal areas therefore accounted for approximately 45% of all new permits.
According to the Tinsa report cited by Valencia Plaza, this represents historic highs in the post-2007 property bubble period and reflects an attempt by developers to respond to strong demand.
Almassora and Benicarló stand out in home sales
The evolution of transactions varies considerably between municipalities.
In the northern and central areas of the Costa de Azahar, Almassora and Benicarló recorded particularly strong growth, with home sales increasing by 22% and 33%, respectively.
In the south of the province, Burriana, Xilxes, Moncofa and Nules also recorded increases of more than 10%.
Meanwhile, transactions declined in municipalities including Benicàssim, Peñíscola, Oropesa del Mar, Torreblanca and Vinaròs.
Oropesa del Mar leads the number of property transactions
Despite experiencing a decline compared with the previous year, Oropesa del Mar recorded the highest number of transactions among the coastal municipalities, with 1,309 home sales.
It was followed by Burriana with 888 transactions, Moncofa with 720, Almassora with 702, Benicarló with 711, Vinaròs with 686 and Peñíscola with 665.
These figures highlight the significant volume of activity concentrated in several coastal towns.
Foreign buyers strengthen the real estate market
International buyers are another important factor behind the coastal market’s dynamism.
According to the report cited by Valencia Plaza, foreign buyers account for around 20% of purchases in some municipalities. Domestic demand mainly comes from central Spain, the Valencian Community, Aragón and the Madrid region.
International demand is predominantly made up of European residents.
This buyer profile contributes to maintaining strong interest in real estate properties along the coast.
Holiday homes are becoming more expensive
Growing demand is also reflected in property prices.
During the first quarter of 2026, the value of holiday homes along the Castellón coast was significantly above the provincial average.
Between Vinaròs and Castelló de la Plana, the average price was around €3,000 per square metre, while between Borriana and Playa de Almenara it stood at approximately €1,750 per square metre. Across coastal municipalities, the average reached €1,588 per square metre.
By comparison, the average home price across the province was €1,328 per square metre.
Benicàssim records the highest property prices
There are significant differences between coastal municipalities.
Benicàssim has the highest average price, at €2,517 per square metre, after increasing 2.2% in one year.
Peñíscola reached €2,021 per square metre following a 26.8% increase, while Alcalà de Xivert reached €1,986 per square metre after an 8% rise.
Torreblanca recorded the largest percentage increase, with prices rising by 53%, although its average price remained lower at €1,484 per square metre.
Demand drives new real estate developments
The significant increase in new-build permits shows that developers are responding to strong demand along the coast.
While new permits increased by 37.1% across the province, the provincial capital experienced a 37% contraction, with only 345 permits.
The coast is therefore becoming increasingly important for new residential supply and overall real estate activity.
Access to property is becoming more difficult
Rising prices are also affecting people looking to buy a home.
The purchase effort for an average household reaches 30% of disposable income in coastal municipalities, compared with 24% both across the province and in the provincial capital.
Although these levels remain within what the report considers reasonable parameters, the greatest difficulties for local residents are currently found in coastal areas.
Conclusion on the real estate boom on the Castellón coast
The Castellón coast is experiencing a period of strong real estate activity. Coastal municipalities accounted for 50% of the province’s home sales in 2025, while new building permits increased by 125.8%. Growing demand, the presence of international buyers and rising prices are turning locations such as Benicàssim, Peñíscola and Oropesa del Mar into increasingly important areas of the residential market.
