urban morphology has adapted. It had to take into account living space for services (racecourse, casino, thermal baths, deluxe hotels, station, hospital and golf, for instance) and the surrounding geography. Aix-les-Bains includes grand boulevards which are the Robert Barrier Boulevard, Boulevard Lepic, Russia Boulevard/President Wilson Boulevard, the Boulevard of Dr. Jean Charcot/Boulevard Maréchal de Lattre de Tassigny and President Franklin Delano Roosevelt Boulevard. These boulevards are wide and open unlike the streets of downtown, which are narrower, and the other axes, which can be more constrained because of the proximity of the Massif des Bauges and its winding climbs, meeting the more anarchic requirements of the moment without taking the urban fabric into overall account. The town includes various neighborhoods such as Chantemerle, Boncelin, around the railway station, the Sierroz, la liberté, the lakeside, Marlioz, Lepic, Franklin Roosevelt and many others. With urban expansion and population growth Aix-les-Bains constantly extends, similarly to the neighbouring communes. Little by little, one speaks beyond a city of Aix-les-Bains as such, but the Aix area encompassing an urban plan, with the nearby communes such as Tresserve, Grésy-sur-Aix, Mouxy, Méry, Drumettaz-Clarafond, Sonnaz, as well as other communes. This phenomenon also applies to Chambéry, which is located south of Aix-les-Bains and is considered as the Chambéry area. The urban morphology of these two local watersheds tends to draw them inexorably closer together. In order to reconcile the urban development of the Aix and Chambéry areas, the joint association of the has been implemented. The mission is to follow the pattern of territorial coherence (SCOT) of the Combe de Savoie, Chambéry and the Lac du Bourget. Housing Aix-les-Bains had 20,317 homes in 2017, of which 15,491 (76.2%) were main residences. 18% of the main residences were built before 1945, and 30% were built after 1990. 22.4% of all houses are detached houses and 76.4% are apartments. 52.7% of the main residences are owned by their occupants, 45.2% are occupied by tenants. 1,837 are HLM rent-controlled housing, or 15.7% of the area in 1999, the city did not meet the provisions of article 55 of the of December 2000, which laid down a 20% minimum rate of social housing in the most important municipalities. It further noted that the number of vacant dwellings was quite high in 1999, accounting for 11.4% of the area. The of the Savoie, with more than 1,657 social homes in the commune, manages
