In Saint-Grégoire, in Ille-et-Vilaine, the average price stands at 3 566 €/m². This residential municipality north of Rennes has a more mixed housing stock than its neighbours: according to INSEE, the French national statistics institute, detached houses sit alongside a large share of apartments, particularly around the recent areas and the business park. The average therefore covers both family houses and apartments, with differences linked to closeness to Rennes and to public transport. This figure comes from DVF data, which records sales actually registered with notaries. It gives a market benchmark and not a valuation specific to your property.

The Saint-Grégoire market is driven by its position as a municipality bordering Rennes, north of the city. The demographic and economic growth of the Rennes metropolitan area, one of the most dynamic in western France, feeds strong demand in the inner-ring municipalities. Saint-Grégoire benefits all the more because its adjacency with Rennes cuts journey times. The scarcity of land close to the centre keeps prices under pressure, while the double supply of houses and apartments widens the pool of buyers. Together this supports an active market that is relatively expensive for the Rennes ring.
The second driver lies in the balanced and well-equipped profile of the municipality. With a large share of apartment buildings, a developed business park and a preserved setting along the canal, Saint-Grégoire attracts varied profiles, from the first-time buyer to the family. This variety makes the market less dependent on a single segment than in purely estate-based municipalities. In return, the high price level for the Rennes ring and the sensitivity of home buying to lending conditions may weigh on sales volume. Precise location, between residential areas and closeness to Rennes, remains decisive.
Saint-Grégoire is among the most highly valued municipalities of the Rennes ring, at a level close to the central city and above several municipalities in the west of the conurbation. The comparison with Rennes, Saint-Jacques-de-la-Lande and Le Rheu sharpens that positioning, without quoting an amount.
Saint-Grégoire, in Ille-et-Vilaine, adjoins the northern edge of the municipality of Rennes, and should not be confused with the municipality of the same name in the Tarn. Its name points to an old religious dedication, a frequent tradition in rural Brittany. Long a farming municipality on the edge of Rennes, it kept an old core before being caught up by the expansion of its neighbouring city. The municipality is bordered by the Ille-et-Rance canal and neighbours Betton, La Chapelle-des-Fougeretz, Melesse and Montgermont. This position as the northern gateway to Rennes, on the roads towards Saint-Malo, shaped its modern growth.
The growth of Saint-Grégoire is closely tied to that of Rennes. Part of Rennes Métropole, the municipality is today among the most populated of that authority, eighth of the forty-three municipalities that make it up. Urban growth sped up from the second half of the 20th century, with estates, apartment developments and the laying out of a large business and retail park to the south, close to Rennes. This double role, residential and economic, sets Saint-Grégoire apart from more strictly estate-based municipalities. The housing stock has grown considerably over recent decades, as shown by the steady rise in the number of homes.
Despite being part of the conurbation, Saint-Grégoire has kept natural spaces, particularly along the Ille-et-Rance canal that borders its territory. The canal, opened in 1832 to link Rennes to the Rance, offers towpaths and walking areas valued by residents. The built heritage mixes older elements of the village with recent construction from residential expansion. This combination of a green setting, immediate closeness to Rennes and well-developed amenities explains the lasting appeal of the municipality and the pressure seen on its property market.
Saint-Grégoire has close to 10 000 inhabitants, according to INSEE, and ranks among the most populated municipalities of Rennes Métropole. Its stock is clearly residential: main residences account for close to 93 % of the homes, against less than 2 % of second homes, again according to INSEE. The municipality stands out for a balanced stock, with around 59 % detached houses and 41 % apartments, a share of apartment buildings higher than in many neighbouring municipalities. This profile attracts both families looking for a house and working households and first-time buyers seeking an apartment close to Rennes.
The average price in Saint-Grégoire, in Ille-et-Vilaine, is 3 566 €/m², according to DVF data drawn from transactions registered with notaries. This average mixes houses and apartments, across all areas. It serves as a general benchmark: the price of a given property depends on its location, its floor area, its condition and its closeness to Rennes. An online valuation lets you refine that figure for your own home.
The Saint-Grégoire stock is fairly balanced: according to INSEE, it counts around 59 % detached houses and 41 % apartments, a share of apartment buildings above that of many suburban municipalities. In practice, a buyer finds here both family houses with gardens and recent apartments, particularly near the business areas and the roads towards Rennes. This double market widens the range of projects, from the first-time buyer to the family looking for space.
Saint-Grégoire directly borders the north of Rennes, which makes it one of the best-connected municipalities of the metropolitan area. The bus network serves the centre of Rennes and the interchanges, and the closeness of the ring road makes car journeys easier. This adjacency with the central city cuts journey times and is a direct driver of demand. The precise location of a property, by its distance from stops and main roads, affects its price.
Saint-Grégoire combines a residential role with a large business and retail park, developed to the south, on the edge of Rennes. This economic presence, with shops, offices and services, provides local jobs and brings life to the municipality beyond housing alone. It sets it apart from the more strictly estate-based municipalities of the area. For a buyer, this means a well-equipped environment, with care to be taken over the choice of area depending on the balance sought between residential quiet and the business hubs.
