The average price recorded in Thiais stands at 3 759 €/m². That average covers a stock where flats largely dominate, between the developments of the Grands Champs, the buildings of the old centre around the church of Saint-Leu-Saint-Gilles and the recent schemes delivered near the future stations. The low-rise detached sectors, still well present, trade at another level but weigh less in sales volumes. The Paris cemetery and the business zones also take up a large share of the territory, which concentrates housing on a few clearly identified sectors. The amounts come from the DVF database, which records the transactions actually registered before notaries.

The first driver of the Thiais market is demographic. The municipality has gained inhabitants in recent years to reach 32 918 residents, on a territory only part of which is buildable, the Paris cemetery and the business zones taking up a large share of it. That land constraint mechanically limits the volume of new dwellings available each year and keeps up the pressure on the existing stock. The high share of owner-occupiers noted by INSEE also slows the turnover of properties, which explains an annual number of transactions that is modest given the size of the town.
The second driver is the improvement in transport. The opening of the Thiais - Orly station on Line 14 in June 2024 puts the municipality a few minutes from the south of Paris and from the airport, whereas it previously had only the RER C and the tramway T7. That new access goes with the development of the Thiais-Orly sector, straddling the Senia zone, where housing, offices and facilities are planned. The urban renewal of the Grands Champs works in the same direction. The effect of these operations is measured sector by sector, not across the whole municipality.
Thiais sits slightly above Choisy-le-Roi and Créteil, but clearly behind Villejuif, closer to Paris and served by the metro for a long time. The municipality holds an intermediate position in this part of the department.
The name Thiais derives from Theodaxium, a Latinised form built on a Germanic personal name. The place appears in the form Theodaxio in the polyptych of Irminon, the inventory of the lands of the abbey of Saint-Germain-des-Prés drawn up at the beginning of the 9th century. The village depended on that abbey and gained its autonomy only in the 13th century. From that long period the church of Saint-Leu-Saint-Gilles survives, whose oldest parts go back to the 12th century, completed in the 15th century, and which is protected as a historic monument. Until the 18th century, Thiais remained a farming village of the plain lying south of Paris, away from the great royal roads.
The village was burned in 1652 during the Fronde. In 1764, Louis XV bought back the lordship from the abbey of Saint-Germain-des-Prés, which had held it since the early Middle Ages. A century later, the municipality found itself on the front line: on 29 and 30 November 1870, during the siege of Paris, Thiais was the scene of violent fighting. The turn of the 20th century was marked by a decision taken in the capital: in 1929, the City of Paris opened a vast Paris cemetery in Thiais, which today covers about 103 hectares, close to 16 % of the municipal territory. That footprint still weighs on the geography of the town.
The second half of the 20th century transformed the municipality in depth. Post-war housing estates rose from the ground, notably at the Grands Champs, a district now engaged in an urban renewal programme. In 1969, the marché d'intérêt national, the national wholesale market, left the Halles de Paris for Rungis and Chevilly-Larue, on the immediate edge of Thiais, one of whose access gates bears the name. In 1971 the Belle Épine shopping centre opened, completed in 2007 by Thiais Village. The Senia business zone and the closeness of Orly airport set the economic vocation of the south of the territory. This juxtaposition of an old village centre, of post-war housing estates, of a cemetery of 103 hectares and of vast business land explains the fragmented shape of the town today.
Thiais has 32 918 inhabitants for 6,43 km², a density close to 5 100 inhabitants per square kilometre, contained by the footprints of the Paris cemetery and of the business zones. According to INSEE, the French national statistics institute, the municipality totals 15 272 dwellings, of which 94,3 % are main residences and 1,8 % second homes: the local market is a market of use. Again according to INSEE, 75,5 % of dwellings are apartments and 19,8 % houses, and 49,5 % of occupying households own their main residence, against 47,8 % tenants. This balance between ownership and renting, uncommon in the inner suburbs of Paris, attracts families who settle for the long term, first-time buyers pushed out of more expensive municipalities and working people employed at Orly or Rungis.
The average price recorded in Thiais is 3 759 €/m², across all sales. That figure comes from the DVF database, which records the transfers actually registered before notaries, and not from online listings. It is a municipal average: depending on the sector, the storey, the condition of the property and the distance to transport, the gap between two dwellings in the town can be marked. A valuation address by address remains necessary before setting a sale price.
The old centre, around the town hall and the church of Saint-Leu-Saint-Gilles, concentrates the shops and a small-scale built fabric that is sought after. The low-rise streets around it form a second sector in demand, with limited supply. The districts of post-war housing estates, including the Grands Champs engaged in urban renewal, show lower values that are also more uneven from one development to another. The south of the municipality, taken up by the Senia, Belle Épine and the Paris cemetery, has few dwellings.
Since 24 June 2024, the Thiais - Orly station, subtitled Pont de Rungis, has linked the municipality to the centre of Paris by Line 14 of the metro. The Pont de Rungis - Aéroport d'Orly station, served by the RER C, lies in the same sector. The tramway T7 runs along the municipality with the stops Porte de Thiais - Marché International, Auguste Perret - Cimetière Parisien and La Belle Épine, and the T9, brought into service in April 2021, serves the northern edge at the Trois Communes stop.
The apartment dominates the market, since INSEE records 75,5 % of dwellings as flats against 19,8 % houses. The share of houses nevertheless remains higher than in most neighbouring municipalities of the inner suburbs, a legacy of the low-rise fabric that surrounds the old village centre. These houses rarely come onto the market and sell above the municipal average, because of the scarcity of the product and the value of the land. For most projects, the useful comparison is with the apartments of the same sector.
It works in both directions. The neighbouring marché d'intérêt national, Orly airport and the Senia zone form a very close employment area, which supports demand for housing from working people who want to limit their commuting. Conversely, road traffic, the noise linked to airport activity and the vast logistics footprints cap the residential appeal of the southern part of the municipality. That duality explains a good part of the price gap between sectors.
