Seine-Maritime is a French department located in the north of the Normandy region. It is defined by its extensive coastline along the English Channel and shares land borders with the departments of Somme, Oise, and Eure. The River Seine flows through the southern portion of the territory, carving a valley through the chalk plateau before reaching the sea.
The housing market is concentrated in the major urban centres, with Rouen holding the largest share of homes, followed by the coastal port city of Le Havre. Property prices across Seine-Maritime are generally lower than the French national average, though costs vary significantly between municipalities. The historic city of Rouen and the residential commune of Bois-Guillaume represent the more expensive areas for buyers. In contrast, the coastal town of Dieppe and the industrial communes of Elbeuf and Le Petit-Quevilly offer far more affordable housing options.
