Recent foreign immigration has become the most important sociodemographic process in Spain. It impinges on many different social aspects, among them, the interrelationship between housing and population. More than 5 million immigrants have arrived during the last 10 years, responsible for about half of new households created since 2001. The size of Spanish demographic change due to immigration, as well as the predominance of a housing model based on home ownership, justifies the interest of the study. Attention will be focused on access to home ownership by long‐standing immigrants, who arrived between 1981 and 1991, observed in the 1991 and 2001 censuses, and compared with Spaniards. Their residential patterns can help us to predict the impact of the current immigration on the Spanish housing system. The conclusions point towards the beginning of a new heterogeneity in the Spanish housing system caused by a deficit of assimilation of the households with immigratory antecedents.
