The average price recorded in Franconville stands at 3 072 €/m². That average covers a mixed stock, where apartments account for a little over three quarters of dwellings and houses for the remaining quarter. The large estates of the 1960s, at l'Épine-Guyon or la Mare des Noues, do not trade at the same level as the houses on the wooded hillsides to the west or as the developments close to the station. Houses trade on average at 4 656 €/m². These amounts come from the DVF database, which records the transactions actually registered before notaries, and not the prices shown in advertisements.

The first driver of the market is demographic. According to INSEE, the population went from 33 196 inhabitants in 2012 to 37 754 in 2023, that is more than 4 500 additional inhabitants in eleven years, on a territory of 6,19 square kilometres that is already largely built up. That growth comes through urban renewal rather than through extension: refurbishment of the large estates, densification around the station and the rebuilt centre. With around 336 transactions a year, the market stays active, fed by the resale of the apartments built in the 1960s and 1970s.
The second driver is accessibility. Franconville lies some twenty kilometres north-west of Paris, linked to the gare du Nord by Line H and served by the RER C, with the A15 and the A115 immediately nearby. That position attracts households from Paris and the Hauts-de-Seine looking for a house or a large floor area at a price level out of reach in the inner suburbs. Retail and public services, the leading local employers, support that appeal, but the market also depends on credit conditions.
Franconville sits well below the neighbouring municipalities of the Hauts-de-Seine and the Yvelines, starting with Maisons-Laffitte and Colombes. The gap narrows with Argenteuil, its neighbour to the south, also in the Val-d'Oise.
The name of the municipality appears in 1137 in the form Francorum Villa, the estate of the Franks, in the will of Suger, abbot of Saint-Denis. In the early 13th century, Guillaume Bateste, a vassal of the barons of Montmorency, is the first identified lord: he had a modest castle built near the present rue de Cormeilles, along with the first church, built in 1210 and destroyed during the Hundred Years' War. Backing onto the wooded hillsides that border the forêt de Montmorency, some twenty kilometres north-west of Paris, Franconville remained until the 18th century a farming village of the valley.
In the 18th century, the municipality became a holiday place for the Parisian middle classes. The chemist Antoine-Alexis Cadet de Vaux settled there and received Benjamin Franklin; the château that carries his name still faces the church, in the centre of the town. The arrival of the railway in 1846, on the Paris to Pontoise line, shifted the centre of gravity of the municipality: a shopping district formed around the station, away from the old village. The rebuilding of the église Sainte-Madeleine stretched over half a century, from the laying of the first stone in 1903 to the completion of the bell tower in 1955.
Mass urbanisation came in the 1960s and 1970s. In 1956, the old centre, the Vieux Pays, was designated a renewal sector: demolition began in 1963 on the avenue de Paris and continued until 1975. At the same time the estates of l'Épine-Guyon, around 600 dwellings, and of la Mare des Noues, built in 1966 on the boundary with Ermont, came out of the ground. The population went from fewer than 12 000 inhabitants in 1962 to nearly 33 000 in 1982. That shift in twenty years explains the town of today: a rebuilt centre, districts of slab blocks and towers, and residential estates on the heights.
Franconville has 37 754 inhabitants over 6,19 square kilometres, which makes it the fifth largest municipality of the Val-d'Oise. According to INSEE, the French national statistics institute, the town has 17 461 dwellings, of which 93,2 % are main residences: the market is residential and second homes are negligible there. Apartments account for 77,7 % of the stock and houses for 22,1 %, a high proportion at this distance from Paris. Again according to INSEE, 57,3 % of households own their main residence and 41,3 % rent, including 18,3 % in the social housing stock. Buyers are mainly families and first-time buyers coming from Paris or the Hauts-de-Seine, looking for more floor space.
The average price recorded in Franconville is 3 072 €/m², across all apartment sales. It comes from the DVF database, which records the transactions signed before notaries, and not from the prices asked in advertisements. That level remains well below the level of the Hauts-de-Seine municipalities a few kilometres away. A given property may depart from it depending on its sector, its storey, its condition and its energy performance certificate.
The town is divided into nine districts: Hôtel de Ville, les Fontaines, Jean Monnet, l'Europe, le Vieux Marché, le Stade, les Noyers de Saint-Edme, l'Épine-Guyon and le Séquoia de la Gare. The large estates of the 1960s, at l'Épine-Guyon and la Mare des Noues, form the bottom of the range. The houses on the wooded hillsides to the west and the immediate surroundings of the station trade higher.
The station of Franconville - Le Plessis-Bouchard is served by Line H of the Transilien towards Paris Nord, every quarter of an hour at peak times and every half hour for the rest of the day, and by the RER C since 1988. The neighbouring station of Cernay, on the same line, serves the east of the territory. By car, the A15 towards Cergy and Gennevilliers and the A115 border the municipality, completed by the lines of the Val Parisis bus network.
Yes, and it is a local feature. According to INSEE, houses account for 22,1 % of the stock, a high proportion for a municipality with more than 6 000 inhabitants per square kilometre. They are concentrated on the wooded heights to the west and in the estates that predate the large blocks. The average price of houses comes out at 4 656 €/m², a marked gap with apartments that owes to the scarcity of land for individual housing.
Franconville belongs to the communauté d'agglomération Val Parisis. The municipality is classified as a tight housing zone: the notice period for a tenant leaving is cut to one month and dwellings left vacant are taxed. A rental permit, free of charge and processed by the conurbation authority, is required in several sectors before any letting. Its perimeter was extended to the Moulin district on 1 July 2025. The document must be attached to the lease.
