Buying a Beachfront Property in Spain: What You Need to Know

A sea view is one of the biggest draws of buying in Spain, but a beachfront address also means dealing with rules most inland purchases never meet. The Ley de Costas protects the shoreline as public domain, and it can limit what you may build, rebuild or extend on a plot close to the water — details that affect both the price you pay now and what a future buyer will be willing to pay for the same home.

If you live in the United Kingdom, buying in Spain also means organising an NIE number, a Spanish bank account, and — once you own the property — understanding how the double taxation agreement between Spain and the United Kingdom affects what you report to HMRC. Because you will be paying in euros from a sterling income, it is also worth planning for exchange-rate movements when you transfer funds for the purchase itself and for any renovation work.

Spain's Ley de Costas treats the shoreline itself as public domain, not something a private deed can override. Behind the beach sits a maritime-terrestrial public domain strip, and further inland runs a protection strip where construction, extensions and even some repairs are restricted by the regional Costas authority as well as the town hall.

For a buyer used to the UK's planning system, this extra layer of coastal law can be unfamiliar. Older homes built directly on or near the sand, sometimes decades before the current rules, may continue under what is called a temporary concession, but rebuilding after serious damage, or adding a floor, may simply not be allowed in the way it would be for a plot set further back from the water. This does not mean a beachfront purchase is a bad idea — many perfectly legal, well-documented homes sit inside these zones — but it does mean the legal check matters more here than for a typical inland property.

A plot affected by the protection strip is not automatically unsellable, but it is usually priced differently from a comparable home set back from the public domain, because its rebuilding and extension rights are narrower. Mortgage valuations, in particular, can come in lower than the asking price for a plot with restricted building rights, which is worth knowing before you agree a reservation fee.

Resale later follows the same logic: a future buyer's lawyer will run the same checks you should run now. A beachfront home with a clear, documented legal situation, inside or outside the protection strip, tends to move through a sale more smoothly than one with an unresolved Costas file. This is one more reason we check a property's coastal classification as part of our standard due diligence, whether you are buying to live in it, let it out, or as part of a managed renovation project.

Working in English, we search both on-market listings and properties that reach us through our network of roughly 1,000 collaborating agencies before they are advertised, arrange viewings in person or by video for buyers who cannot travel straight away, and check a beachfront property's coastal status alongside the usual legal, structural and ownership checks. We coordinate with your lawyer, the notary and your bank, and help with the NIE and account-opening steps described above.

If a sea-view plot needs work rather than a straight purchase, our managed-investment service lets you buy the property in your own name while our own renovation team carries out the refurbishment, after which we sell or let it on your behalf; fees are agreed in advance and we never pool investors' money. Since 2022 our group has bought, renovated and resold 19 homes this way, with a median renovation budget of 22 % of the purchase price — past results, not a promise of what any future project will return. Note too that Spain's property-investor Golden Visa ended on 3 April 2025 and is no longer an option for residence.

Spain is a relatively short flight away from most UK airports, making regular visits to a Spanish property straightforward for owners based in Britain. Many British buyers are drawn to Spain for its climate, coastal lifestyle and established expatriate communities. One practical point to bear in mind is that Spanish inheritance law differs from UK rules, so it is worth taking specific advice on how it may affect the property and one's estate. Currency movements between sterling and the euro can also affect the overall cost of purchase and ongoing expenses.

Spain and the United Kingdom have a double taxation agreement in place, and a local tax adviser should confirm how rental income or gains from Spanish property must be declared and reported to HMRC.

As the United Kingdom is no longer an EU member state, British citizens may stay in Spain for up to 90 days in any 180-day period without a visa, and must apply for a visa or residence permit for longer stays.

Since the United Kingdom uses the pound sterling (GBP) rather than the euro, buyers should factor in exchange-rate movements and currency conversion costs when paying for a property or transferring funds to Spain.
