The average price recorded in Châtillon stands at 5 896 €/m² for an apartment. That average covers a stock made up overwhelmingly of flats, where blocks of the 1960s and 1970s along the avenue de la Division Leclerc sit alongside recent developments from the schemes in the north-east of the commune, and an older fabric of millstone houses inherited from the 1930s. Houses and villas, far fewer, come out around 7 793 €/m². The distance to the terminus of metro line 13 explains much of the gaps from one sector to another. These amounts come from the DVF database, which lists sales actually registered before notaries.

The market in Châtillon is driven first of all by its terminus position. Since 1976, line 13 has put the commune a few minutes from Montparnasse, and the T6 tramway widened the catchment in 2014 towards the western Hauts-de-Seine and the Yvelines. That accessibility draws households looking for closeness to Paris without paying its price level. The population, steady at 36 705 inhabitants, is slightly down on 2017, a sign that growth now depends on new schemes more than on the densification of the existing fabric.
The second force at work is the conversion of the north-east of the commune. The former area of offices and workshops is giving way to a mixed district, the ZAC des Arues, combining housing, offices and public facilities, within the perimeter of the future line 15 station. These deliveries bring into the stock recent homes whose price levels differ markedly from those of the 1960s blocks. Conversely, the stock of detached houses is not growing: their scarcity keeps the gap with flats wide.
Châtillon sits in the upper middle range of the south of the department, above Bourg-la-Reine but behind Sceaux. The gap becomes clear against Boulogne-Billancourt, which plays in another price category.
The name Châtillon comes from the Latin castellum, a small stronghold, and appears in the records in 1192 under the reign of Philip Augustus. The lordship then belonged to the abbey of Saint-Germain-des-Prés, which kept it until 1600. The village formed around an old centre where buildings of the 18th and 19th centuries survive, notably around rue de Fontenay and rue Gambetta. In 1815, after crossing the Seine at Sèvres, English troops occupied the heights overlooking the valley and plundered the town. This plateau relief, commanding the southern approach to Paris, was to shape the commune's military and then urban fate for a long time.
The war of 1870 put Châtillon at the centre of the fighting: the plateau was contested from 17 to 19 September, then again on 13 October. The lesson was drawn in the following decade with the building, from 1874, of a fort forming part of the fortified belt of Paris, straddling Châtillon and Fontenay-aux-Roses. On 5 October 1944, a V2 rocket crashed on the commune. In July 1946, the fort became the first research centre of the Atomic Energy Commission, headed by Frédéric Joliot-Curie: the Zoé pile, the first French atomic pile, was inaugurated there on 15 December 1948. The site was renamed the Fontenay-aux-Roses nuclear research centre in 1957.
Long called Châtillon-sous-Bagneux, the commune took back its plain name in 1983. It was attached to the Hauts-de-Seine in 1968, following the administrative reorganisation of the Paris region decided in 1964. The decisive turning point was the extension of the metro: on 9 November 1976, line 13 reached the Châtillon-Montrouge station, which became its southern terminus and fixed the town's centre of gravity for forty years. The T6 tramway, opened on 13 December 2014, connects there and runs to Viroflay. The former business area in the north-east is now the subject of a mixed development scheme, the ZAC des Arues, combining housing, offices and public facilities.
Châtillon has 36 705 inhabitants according to INSEE, the French national statistics institute, spread across around 17 600 households, for a density close to 12 500 inhabitants per square kilometre. The stock counts 18 866 dwellings, of which 92,1 % are main residences and 5,1 % vacant homes: people buy here to live, not to spend the summer. Apartments account for 85 % of dwellings and houses 12,8 %. The split between owners (48,2 %) and tenants (49,2 %) is almost even, which reflects a market open as much to first-time buyers as to long-term investors. The average household size, 2,08 people, steers demand towards one- and two-bedroom flats.
The average price of apartments in Châtillon comes out at 5 896 €/m², calculated on sales actually registered before notaries and published in the DVF database. It is a town-wide average: a studio in a 1970s block and a new apartment delivered near the terminus of line 13 do not sit at the same level. For your property, only a valuation taking account of the address, the floor level and the condition can approach the real value.
Three logics sit side by side. The old town centre, around rue de Fontenay and rue Gambetta, keeps a low-rise older fabric valued for its scale. The surroundings of the Châtillon-Montrouge terminus concentrate the demand tied to journey time into Paris. Finally, the fabric of 1930s detached homes, with its millstone houses, forms a market of its own, rarer and hotly contested, where sales are few each year.
Châtillon-Montrouge has been the southern terminus of metro line 13 since 9 November 1976, giving direct access to Montparnasse and then Saint-Lazare. The T6 tramway, opened on 13 December 2014, leaves from the same hub and serves the west as far as Viroflay. Several bus routes complete the service towards Vanves, Malakoff and Bagneux. This terminus position is a constant selling point in the commune's listings.
The question hardly arises in practice: apartments account for 85 % of the stock according to INSEE, against 12,8 % houses. The supply of houses is therefore structurally scarce, concentrated in the developments of the 1930s and 1950s, and trades around 7 793 €/m². A buyer aiming for a house has to accept long search times and strong competition. For a tight budget, the apartment remains the realistic way into the commune.
Châtillon-Montrouge is among the stations of line 15 South of the Grand Paris Express, which is to link the inner-suburb communes to one another without going through Paris. The current hub, already served by the metro and the tramway, therefore becomes an interchange node. The development schemes under way nearby, including the ZAC des Arues, fit into that perspective. The effect on prices cannot yet be read separately in the sales data, however.
