Buying a House with Sea View in France
A sea view remains one of the most sought-after—and most misunderstood—criteria in luxury French real estate. Before giving in to impulse, a discerning buyer should be aware of regulations that have been quietly shaping the entire French coastline for forty years: the Coastal Law.
A law that has protected the coast since 1986
Adopted unanimously on January 3, 1986, the Coastal Law regulates urban development in more than 1,200 municipalities bordering the sea, large lakes, estuaries, and deltas. Its central principle: all new construction must be contiguous with existing urban development—an isolated plot of land, even if zoned for construction according to the local urban development plan, can be refused a building permit solely on the grounds of the Coastal Law.
The 100-meter zone, a rule you absolutely need to know
Outside of already urbanized areas, all construction is prohibited within 100 meters of the high-water mark. This rule explains why some seemingly ideal plots of land, with direct sea views, remain unbuildable despite being designated as buildable zones in the Local Urban Development Plan (PLU). Checking the operational urban planning certificate from the town hall before making any offer remains the best protection against a costly disappointment.
The risk of erosion, an increasingly decisive factor
Beyond the Coastal Law itself, Coastal Risk Prevention Plans (PPRL) sometimes reinforce restrictions in areas exposed to coastal erosion or marine submersion. Coastal retreat, accelerated in some places, makes certain plots of land currently zoned for construction potentially at risk in the coming decades—a point to consider in any long-term purchase decision, in addition to the usual property valuation.
What remains possible despite these constraints
These regulations don't prevent buying properties with sea views—they simply guide buyers toward prime locations: properties situated within existing urban areas, residences built before 1986 (often the best situated), or densely populated urban areas where the regulations are more flexible. The scarcity imposed by the Coastal Law is, in fact, one of the reasons why properties with sea views maintain a particularly stable property value in France.
