Buying a seaside property in France: the buyer’s guide

How much does a house by the sea cost in France?

The price of a house by the sea depends first of all on its relationship to the water: the view, the frontline position, direct access to the shore. The sales published by the tax authority (the DVF register) put a figure on it: in Saint-Tropez, the median for houses reaches €18,600/m², against €5,100/m² across the Var as a whole (DVF / DGFiP via data.gouv.fr, April 2026 release, 2025 sales).

Within a single market the range remains wide: in the commune of Lège-Cap-Ferret, a tenth of houses sold for less than €3,500/m² and a tenth for more than €18,800/m², without DVF saying which of them had the view. For a house, the DVF price per square metre divides the total price, land included, by the built floor area: a large garden facing the sea pushes the figure up.

Beachfront, seafront, sea view: what the listings say

No general right protects a view: it rests only on the planning rules for the plots in front, which can change, and sometimes on an easement recorded in the deeds that prohibits building there or exceeding a certain height. When you pay for a view, this is the first check to make.

What are the main coastal property markets in France?

The main coastal markets stretch from the Côte d’Azur to Normandy, and seaside property for sale in France differs from one to the next, in price and in type of property: in the table, the top decile marks the upper end of the market, and the number of sales its depth, useful for comparing and, later, for reselling.

• Côte d’Azur, the French Riviera: seafront apartments in Nice, Cannes or Antibes, villas on the capes as far as Saint-Jean-Cap-Ferrat, where most large properties change hands without being advertised.
• Provence: from Cassis to Sanary-sur-Mer, via La Ciotat, Saint-Cyr-sur-Mer and Bandol, a coast of calanques (rocky inlets), harbours and vineyards.
• Basque Country: neo-Basque villas and apartments facing the ocean, from Biarritz to Saint-Jean-de-Luz, where frontline properties remain rare; see buying a villa in Biarritz.
• Atlantic Coast: villas under the pines of Cap Ferret, village houses on the Île de Ré, where many change hands within families.
• Brittany and Normandy: Belle Époque villas in Dinard, the Gulf of Morbihan around Vannes, half-timbered houses in Honfleur, villas in Deauville.

What does the Loi Littoral (coastal law) change when you buy a house?

The Loi Littoral of 3 January 1986 does not limit the right to buy: it limits what you will be able to build, extend or add afterwards. It applies in coastal communes, including those that border a lake of more than 1,000 hectares.

• The 100-metre coastal strip: counted from the upper limit of the shore, it is unbuildable outside urbanised areas, and the local urban plan (plan local d’urbanisme, PLU) may widen it where erosion or the sensitivity of the environment justify it.
• Continuity: urbanisation extends in continuity with existing towns and villages; an isolated plot among a few scattered houses is in principle not buildable.
• Areas close to the shore (espaces proches du rivage): the extension of urbanisation is allowed there only to a limited degree.
• Protected outstanding natural areas (espaces remarquables): certain dunes, cliffs, coastal heathland or wetlands allow in principle only light developments.

On an urban seafront that is already built up, the 100-metre coastal strip therefore does not freeze everything. The rule that surprises most people lies elsewhere: the Loi Littoral applies directly to planning authorisations. On a plot classed as buildable by the local urban plan, a building permit can thus be refused, or annulled on a third party’s appeal.

Extending, adding a swimming pool: check before making an offer

If your project rests on an extension, a swimming pool or an outbuilding, have it reviewed by an architect or a planning lawyer before signing, and provide in the preliminary sale agreement (avant-contrat) for a condition precedent of obtaining the planning authorisation (a building permit, or non-opposition to a déclaration préalable, the prior declaration of works), free of any appeal. An existing extension built without authorisation can also block your own works.

Marine flooding, erosion, coastline retreat: how do you assess the risks?

Coastal risks are checked from the documents, before the offer: the risk report (état des risques), which the seller hands over from the first viewing, the commune’s risk prevention plan if there is one and, where the law requires it, the coastal erosion map (recul du trait de côte).

Marine flooding is an event: a storm and a high tide combine, and the sea breaches the defences, as with Storm Xynthia in February 2010 on the Atlantic coast. Erosion is a process: the coast retreats, slowly or in sudden bursts. Since the Loi Climat et Résilience (Climate and Resilience law) of 2021, communes listed by decree must map the zones exposed to coastal erosion within thirty years and between thirty and one hundred years, where building is very tightly regulated.

• Is the property within the perimeter of a risk prevention plan, and in which zone?
• Is the plot in a zone exposed to coastal erosion?
• Which claims have been paid out for a natural disaster? The seller must declare in writing those they know of.
• What structures protect the plot (sea wall, rock armour, wall), and who maintains them?
• What does the insurance cover? Flooding during a storm and the gradual retreat of the coast are not treated in the same way.

The public Géorisques website gives a first reading for the address; the height of the plot above the sea, the dune or cliff and the condition of a retaining wall are observed on site.

What should you inspect on a building exposed to the sea?

A building by the sea ages faster than one inland: salt spray attacks metals and façades, wind tests roofs, windows and doors, damp creeps into houses closed for part of the year. All of this can be checked, and costed, before the offer.

• Metals: railings, ironwork, fixings; marine-grade stainless steel (316) and aluminium powder-coated for seaside use resist better than ordinary steel.
• Reinforced concrete: cracks, spalling and exposed reinforcing bars on balconies betray corrosion that is costly to treat.
• Windows, doors and roof: watertightness of the openings facing the prevailing wind, fixing of tiles or slates, ridges, flashings.
• Damp: ventilation, condensation, mould, saltpetre (salt efflorescence) at the foot of walls; a house closed in winter is also judged by its smell.
• Equipment: a heat pump exposed to sea spray, the pool’s plant room, the electrical panel.

In a seafront co-ownership, the question becomes collective: read the minutes of the general meetings of co-owners for the last three years, the multi-year works plan if there is one and the amount of the works fund. Façade renovation, balconies and railings recur more often facing the sea, and each co-owner pays their share.

Depending on the commune, further items are added: the termite report, in zones delimited by prefectoral order (numerous along part of the Atlantic seaboard), and the information on the risk of dry rot (mérule), where an order requires it (information, not a diagnostic report). Where there is no mains drainage, the inspection of the septic / non-mains drainage system must be less than three years old, and a non-compliant installation requires works within the year following the sale.

Can the shore be bought?

No: the shore belongs to the public maritime domain (domaine public maritime), which cannot be bought. A beachfront property stops where the shore begins, and anything installed beyond it requires an authorisation.

The shore extends up to the limit of the highest tides, in the absence of exceptional weather disturbances. It is inalienable: no title deed can include it, even when a garden seems to extend into it. And its boundary follows the sea: the part of a plot that the highest tides come to cover falls within the public domain.

• Pedestrian access: properties bordering the sea are subject to a public pedestrian right of way over a strip 3 metres wide, with the exceptions provided for by law, notably in the vicinity of houses built before 1976.
• The beach: unrestricted, free-of-charge public use is the rule; a house facing the beach has no exclusive right to it.
• The jetty, the slipway, the steps down to the sea: on the public domain, they are lawful only under a temporary occupation permit (AOT, autorisation d’occupation temporaire), which is personal, precarious and revocable and does not automatically transfer with the sale.
• The mooring: a buoy in front of the house is also subject to authorisation, either an individual one or one within an organised mooring zone.
• The harbour berth: as a general rule it depends on the port operator and its waiting list, not on the seller.

Living by the sea all year round or for the season: what changes?

You do not choose the same house by the sea to live in all year round as for a few weeks: out of season, many resorts slow down, and neighbourhood life, services and access then matter more than the view.

Before buying to live there, judge the commune in November, not just in August: shops, doctors, schools, railway station, airport. La Rochelle, Vannes, Saint-Malo, Nice or Biarritz are lived in all year round, as is Sanary-sur-Mer with its village life; other, very residential markets empty out of season.

Seasonal letting: a stricter framework

The law of 19 November 2024 extended registration to all furnished holiday lets (meublés de tourisme), strengthened the tools available to communes and made taxation less favourable. Some coastal communes already regulate such lettings, as Saint-Malo does (see the property finder in Saint-Malo page), and the co-ownership rules (règlement de copropriété) may restrict them: check both before the offer if the letting finances part of the project.

A second home is also subject to the residence tax (taxe d’habitation), which communes in high-demand areas (zones tendues), many of them on the coast, may increase by 5 to 60%. Between your stays, the Home Select concierge service looks after the property, billed for time spent and by quotation, from seasonal openings to the coordination of works.

How do you negotiate a property by the sea?

By the sea, negotiation is won on timing and on proof: the most favourable windows often open out of season, and only precise comparables make it possible to challenge a price that the view appears to justify.

• Timing: buyers crowd in during spring and summer; autumn and winter leave less competition, and a property advertised for several seasons has not found its price.
• Comparables: a commune’s median says little about a frontline villa; only DVF sales on the same street and of the same type, read alongside the exposure of each address, make an argument.
• Works and constraints: a roof, metalwork or drainage to be redone is costed by quotation; a risk zone, an extension that cannot be built or a right of way weigh on the value.
• Scarcity: on the most contested properties, the terms (timescales, the date you take possession) matter as much as the price.

On average, Home Select negotiates 6% off the asking price. That is not a promise property by property: a rare, coveted villa leaves little room for negotiation, an overpriced house or one needing renovation more.

How does Home Select search for a property by the sea?

Home Select runs the coastal search remotely, under the direction of its management, and draws on a network of 15,000 professional partners (agents, notaires, managing agents), which brings it at least 100 off-market properties a day, as well as on automated monitoring of 1,700 listing sites.

• A first conversation by video call or phone, then a written brief: use, stretch of coast, budget, constraints.
• The hunt, and the vetting of each property on documents: planning, the Loi Littoral, the risk report, co-ownership.
• A commented video pre-viewing and an analysis sheet for every shortlisted property, the sea-facing façade included; you come only for the decisive viewing.
• The price analysed address by address against DVF sales, the negotiation and the securing of the preliminary sale agreement.
• Coordination of the notaire, the mortgage broker and the diagnostic surveyors up to the deed, which can be signed remotely, as the guide to buying remotely details.

Two offers, the same full service: the Exclusive offer (exclusive mandate, 2.5% incl. VAT of the net purchase price, minimum €10,000 incl. VAT) covers the whole market, listings and off-market; the Confidential offer (simple mandate, 1.5% incl. VAT, projects of €2m and above) presents off-market properties only. In both cases, 100% on success: nothing is due before the signing of the authentic deed. The detail is on the fees and method pages.

Each market has its own page, with its neighbourhoods, its prices and its points of vigilance: property finder in Biarritz, property finder in Arcachon or property finder in Deauville.
