The average price recorded in Clamart stands at 5 678 €/m². That average covers a highly contrasting stock: according to INSEE, the French national statistics institute, around 73 % of dwellings are apartments, the rest forming a dense fabric of detached houses inherited from the housing developments of the early 20th century. The gaps play out between the lower part of the commune, around the station and the old centre, and the plateau, closer to the bois de Clamart and the estates built after the war. The age of the buildings and transport links also weigh. These values come from the DVF database, which lists sales actually registered before notaries.

The first driver of the Clamart market is better transport. The commune has gained two tramway lines in less than ten years, the T6 towards Châtillon and Viroflay in 2014, then the T10 towards Antony in 2023, which opened up the upper part of the town. The announced arrival of line 15 South of the Grand Paris Express at Clamart station, at the end of 2026, places the commune on the automatic metro orbital linking the employment hubs of the southern Paris region. That timetable is closely watched by buyers and sellers alike.
The second driver is the output of new housing, still possible here while it is blocked in most neighbouring communes. Two sectors are being developed, the former EDF land at Le Panorama and the Canaux district along departmental road 906, with a programme mixing private housing, social housing, shops and public spaces. To this are added stable local employers, the Percy and Antoine-Béclère hospitals, and a quality of setting carried by the state forest of Meudon, which covers a large share of the commune's 877 hectares.
Clamart sits in the upper middle range of the southern Hauts-de-Seine, above Bourg-la-Reine but behind Sceaux. The gap stays very wide with Boulogne-Billancourt, whose levels belong to another market segment.
The name Clamart is thought to derive from the Gaulish Clunia-maros, the great meadow. The village took shape in the 11th century around the Saint-Pierre-Saint-Paul church, in an economy of ploughmen and winegrowers whose wine remained well regarded into the 19th century. The commune owes its fame above all to its garden peas, grown on its land and served at royal tables: the culinary term à la Clamart, for a garnish of fresh peas, still carries the trace. Clamart gained its status as a commune in 1790. In 1840, the opening of the Paris-Versailles left-bank railway line brought the village into the orbit of Paris.
From 1856, the mayor Jules Hunebelle modernised the commune, with gas lighting and a water supply, to the point of being nicknamed the Haussmann of Clamart. The population went from around 1 220 inhabitants in 1831 to more than 12 000 in 1915. Parisians came to take the air, middle-class villas rose on the woodland edge, and a second station was built in 1904. The Jardin Parisien development, begun in 1907, opened the long series of housing subdivisions that gave the upper part of the commune its grid of narrow streets and houses on small plots, still readable today.
After the two world wars, the commune took in new residents in the districts of Trivaux-Garenne, the cité de la Plaine and the Jardin Parisien. On 1 June 1961, the collapse of former chalk quarries in the Monts district killed 21 people and destroyed 23 buildings over more than six hectares: the subsoil has been a defining constraint on building ever since. On 22 August 1962, the failed attack on General de Gaulle gave Le Petit-Clamart national notoriety. In 1982, the first French test-tube baby was born at the Antoine-Béclère hospital. From this history in successive layers comes the scattered shape of the town, divided into seven districts and split by the relief between a lower Clamart and an upper Clamart, over 877 hectares largely covered by woodland.
Clamart has 58 576 inhabitants according to INSEE, for around 28 150 dwellings. Main residences account for more than 91 % of them, which describes a town lived in all year round, with no market for pieds-à-terre. The stock is mainly made up of flats, with around 73 % apartments, but the commune keeps close to 7 200 detached houses, the legacy of its successive developments. The split between owners and tenants is almost even, at around 51 % owner-occupiers, and social housing weighs around 23 % of main residences. Buyers are mainly working households employed in Paris or in the Vélizy business hub, looking for family floor space and quick access to the centre of the capital.
The average price per square metre in Clamart stands at 5 678 €/m². That figure is calculated from the DVF database, which lists sales actually registered before notaries, not listings. It is a town-wide average: a studio in a 1960s block on the plateau and a renovated house near the wood depart from it clearly. An online valuation places your property more precisely.
The town is divided into seven districts. Lower Clamart, around the old centre, the Saint-Pierre-Saint-Paul church and the station, concentrates demand, along with the streets of detached houses bordering it. The surroundings of the bois de Clamart and the forest of Meudon are also sought after for their setting. The sectors of La Plaine and Trivaux-Garenne, marked by the post-war estates, show lower values.
Clamart station is served by Transilien line N, with a direct link to Paris-Montparnasse. The T6 tramway, opened on 13 December 2014 between Châtillon and Viroflay, crosses the commune, and the T10 has linked it to Antony since 24 June 2023, with a terminus at the Jardin Parisien. Clamart station is due to take line 15 South of the Grand Paris Express, whose opening is announced for the end of 2026.
The two markets genuinely sit side by side, which is rare in the inner suburbs. According to INSEE, the commune counts around 73 % apartments but also close to 7 200 detached houses, born of the developments opened from 1907. These houses are concentrated in the upper part of the commune, often on small plots and in narrow streets. They change hands less often than apartments and trade above the town-wide average.
Part of the Clamart subsoil is taken up by former chalk quarries, whose collapse on 1 June 1961 was a reminder of the danger. These areas are recorded by the General Quarry Inspectorate and can govern foundations as much as building work. The statement of risks given to the buyer must mention them. For an apartment, the co-ownership documents, the statement of charges and the minutes of general meetings should be gathered early: they govern the timetable of the sale.
