"Near the sea" is the most used and least defined phrase in Spanish property listings. It covers a flat with the promenade outside the window and a villa on a hill fifteen minutes' drive from the sand. Before you pay a premium for the word, it helps to know what the three coastal zones really are, what the coastal law allows on each of them, what the sea does to a building, and what the distance is actually worth in euros.
This guide is written for a buyer choosing between a front-line home and one a few streets back on the Costa Blanca, the Costa del Sol, the Costa Cálida or Mallorca. The rules are the same on every Spanish coast; the prices and the stock are not, and we say where they differ.
How we measure. Every listing on this site carries a distance to the sea measured in a straight line from the building to the nearest shoreline, not walking distance to a named beach. A home 600 m from the water can still be a ten-minute walk to the sand if a road, a cliff or a marina sits in between. The near-the-beach catalogue lists everything within 1 km, closest first.

Three zones from the water
Agents and portals use "first line", "second line" and "near the sea" loosely. In practice the coast divides into three bands that behave differently in price, in law and in upkeep.
| Zone | What it means | What you get |
|---|---|---|
| First line (primera línea) | Nothing but the promenade, a road or the beach itself between the building and the water | Sea view from most rooms, direct access, the strongest resale demand and the highest exposure to salt and wind |
| Near the sea (up to about 1 km) | A short walk to the beach; the sea may or may not be visible | Most of the coastal stock, a quieter street, a lower price per square metre than the front line |
| Coastal, inland (beyond 1 km) | Hillside and golf communities, older towns behind the coast | Bigger plots, views over the bay from elevation, a car to reach the beach |
The first two bands are what this guide is about. On our own catalogue the first line is almost entirely apartments: villas on the sand are rare on every Spanish coast because the front-line plots were built on decades ago, and today's villas near the sea sit on cliffs and hillsides with the view rather than the beach at the door.
The coastal law, in plain words
Spain's Ley de Costas draws lines inland from the shore, and each line changes what an owner may do. The lines matter most for older front-line homes, so it is worth reading them once.
- Public maritime domain (art. 3): the beach itself and the shore up to the reach of the biggest storm waves belong to the State. Nobody owns a beach in Spain.
- Right of way, 6 m (art. 27): a strip of at least 6 m behind the public domain line, extendable to 20 m where passage is difficult or dangerous, must stay open for pedestrians. In practice this is where the promenade or the path along the rocks runs.
- Protection zone, 100 m (art. 23), measured from the inner edge of the public domain; inside it new homes are prohibited (art. 25). Where land was already classified as urban when the law came into force in 1988, the zone is 20 m instead, which is why the old seafront blocks of Benidorm, Calpe or Fuengirola stand where a new building could not.
- Influence zone, 500 m (art. 30): planning rules within half a kilometre must avoid architectural screens along the shore and keep building density to the average of the town's existing built-up land.
For a buyer the practical consequences are these. A new-build on the first line is legal because it stands behind the protection line, usually on the last plots of an urban seafront or on the site of a demolished older building. An older home inside the 20 m or 100 m band is not illegal: the 2013 reform expressly allows repair, improvement, consolidation and modernisation works, provided they do not increase the volume, height or footprint, and provided the works improve the building's energy rating. The owner files a declaración responsable with the regional administration instead of applying for a permit, and works that touch the 6 m strip still need state consent. A home that stands on the public domain itself, which happens on a few old seafronts, is held under a concession rather than freehold, and since 2013 such concessions can be extended to a combined maximum of 75 years.
Before you reserve a front-line resale: ask your lawyer for the deslinde, the official demarcation of the coastal lines for that stretch, and check which band the building falls in. It decides what you can rebuild, how far you can extend, and whether you are buying freehold or a concession. The buying process guide covers the rest of the legal checks.
What the distance is worth
The premium for the sea is real, and it steepens sharply in the last few hundred metres. On our catalogue in September 2026, the median asking price per square metre was:
| Distance to the shoreline | Median asking price, €/m² | Against homes beyond 1 km |
|---|---|---|
| Up to 200 m (the front line and the street behind it) | €5,650 | about +44% |
| 200 m to 1 km | €4,300 | about +9% |
| Beyond 1 km | €3,930 | – |
Two things sit behind those figures. The first line is scarcer than anything else on the coast: the land is finite, the law forbids building closer, and owners of seafront homes sell rarely, so resale supply is thin and buyers compete for it. And the front-line stock is skewed towards newer apartments in the resort towns, which are dearer per square metre than the villas and townhouses that dominate further inland. The gap between 200 m and 1 km, on the other hand, is modest: a five-minute walk costs surprisingly little.
The coasts are not equal. The Mar Menor and the southern Costa Blanca around Torrevieja are the cheaper shores; the northern Costa Blanca from Calpe to Jávea and the Marbella–Estepona stretch of the Costa del Sol are the dearest. The Costa Blanca, Costa del Sol and Costa Cálida lists show the current stock within 1 km on each.
What the sea does to a building
Salt air is the price of the view. Within the first few hundred metres of the shore it settles on everything, and the difference between a front-line home that ages well and one that does not is mostly in the specification and the maintenance budget.
- Metal. Railings, hinges, window frames and outdoor fittings corrode fast unless they are marine-grade stainless steel or coated aluminium. On a viewing, look at the balcony railings and the air-conditioning units: rust streaks on a building under ten years old tell you how the community maintains it.
- Glazing and blinds. Sealed double glazing and aluminium or PVC frames with good seals keep the salt and the wind out; old wooden frames and exterior blinds need repainting or replacing every few years.
- Facades and terraces. Seafront buildings repaint and re-seal more often than inland ones, and the cost lands in the community fees. Expect the comunidad of a front-line block with lifts, pools and a large facade to charge more than a similar block three streets back.
- Humidity. Ground-floor and north-facing units near the water are the dampest. Cross-ventilation, a dehumidifier in the closed months and a heating source matter more here than anywhere else on the coast.
Insurance is simpler than most buyers expect. Every home policy in Spain carries a compulsory surcharge for the Consorcio de Compensación de Seguros, the state pool that pays for extraordinary events: floods from rivers, torrential rain and storm surge, and atypical cyclonic storms. That is where a seafront claim after a big winter storm goes. What the Consorcio does not cover is rain that comes in through your own roof or terrace, which is ordinary home insurance, so check that the policy's water-damage cover is not capped too low for a home that faces the weather.
New-build near the sea
The idea that nothing new is built by the water is out of date. On our catalogue most homes within 1 km of the sea are new-build, and the first line itself has new projects in a handful of places: Estepona's western beaches, Villajoyosa, Benidorm's Poniente, Calpe and La Manga in our current selection. They stand on the last free plots of an urban seafront or replace an older building, which is why they are few and why phases sell early.
Buying new near the sea follows the usual staged plan: reservation, contract, instalments during construction, balance at completion, with bank guarantees on the money paid before delivery. Two checks are specific to the coast. First, the building must stand outside the protection zone; your lawyer reads this off the deslinde and the planning file behind the licence. Second, the specification should name the corrosion-resistant materials for the exterior, because a seafront project built to an inland spec will look tired within five years. The energy certificate is worth reading too: a front-line apartment with a poor rating is expensive to keep comfortable in a wind-facing position.
Finding it on this site
The near-the-beach catalogue shows every home within 1 km of the shoreline, sorted by distance, so the first line comes first. The same list exists by type, apartments and villas, by region and by town where there is enough stock. In the catalogue's advanced search the "near the beach" feature takes you to the same pages, and each listing shows its measured distance to the shoreline.
If you are weighing a front-line resale against a new-build a few streets back, the honest comparison is total cost over ten years, not price per square metre on day one: the view is permanent, but so are the maintenance and the community fees that come with it.
