Note
Coastal erosion when buying a home in Spain
Quick answer
The ministry’s national plan for the coast focuses mainly on managing erosion risk and has regional strategies for seven stretches. Ask the coastal service whether the shoreline near the plot is retreating, what works are planned and where the legal protection line runs. We found no official retreat figure.
Applies toBuyers considering homes near the beach, cliffs or low-lying coast.

§ 1What the ministry says
The ministry in charge of the coast has a national strategic plan for its protection, which it presents as a coherent national approach that regional and local measures must complement. It says the plan focuses mainly on managing the risk of coastal erosion and that it incorporates adaptation to climate change. The ministry has also developed regional strategies for seven areas: Huelva, Maresme, southern Castellón, southern Valencia, Granada, Cádiz to Almería and the Balearic Islands. The page contains no figures on kilometres affected or rates of retreat. This page belongs to the chapter on natural risks explained.
§ 2What it means for a buyer
If the home is on one of the stretches with a regional strategy, there is a recognised erosion problem there. If it is elsewhere, the lack of a strategy does not prove that the coast is stable. Ask the coastal service of the ministry, through its provincial office, whether the stretch is eroding, what works exist or are planned and what the line of protection is. Ask for the answer in writing.
§ 3Look at the ground
Look at the beach in front of the plot in winter if you can. Narrow beaches, exposed foundations, rock armour, concrete walls and repeated repairs suggest a coast under pressure. On cliffs, look for cracks, landslips and water running over the edge. A cliff-top home has a risk that a sea-level home does not.
§ 4The legal frame
The coastal law protects the public coast, defines a protected strip and limits what can be built or kept there. Our legal checks section explains the part of the law we read and says where we could not read it. A home on the sea side of the line, or inside the protected strip, can carry limits on works and a different legal status. The ministry’s own plan is not a substitute for that check.
§ 5Storms
Sea storms can damage promenades, basements and garages near the shore, and they combine with heavy rain in autumn. The state compensation body pays for sea surge and other extraordinary events when the policy carries its surcharge, as Consorcio de compensacion de Seguros flood explains. Ask the insurer whether your policy does. DANA flash floods explained explains the rain pattern that often comes with them.
§ 6Public works
The ministry announces projects to regenerate beaches and adapt the coast, including some for the Valencian coast. A project can be delayed, changed or cancelled, and it does not change the legal status of your home. Do not pay a premium for a plot on the strength of a planned work.
§ 7Value and resale
A buyer will ask the same questions you ask. A home with a clear answer on erosion, the protected strip and works will sell more easily than one with doubts. Keep the written answers with the property papers.
§ 8What we could not verify
We found no official figures for retreat rates and we did not read the regional strategies in full.

FAQRelated questions
Is erosion a problem everywhere on the coast?
No. It is concentrated in certain stretches, and the ministry’s strategies target places where it has found the greatest problems so far. Beaches and cliffs behave differently, so ask about the exact stretch.
Can the state demolish a coastal home?
The coastal law sets protected zones and conditions for existing buildings. We read it only in part, so ask your lawyer how it applies to this plot. The coastal section of the legal checks explains the reading we completed.
Does the state repair beaches?
The ministry runs projects to regenerate beaches and strengthen the coast, and some are announced for the Valencian coast. These are public works that can change, so do not rely on a planned project as a reason to buy.
