Atmospheric illustration of Groisy, a municipality of hills between Annecy and Geneva, in Haute-Savoie.
The average price recorded in Groisy stands at 5 059 €/m². This average covers a stock dominated by houses, a little over 60 % of dwellings according to INSEE (France's national statistics institute), in a municipality of hills set between Annecy and Geneva. Houses and villas, very present here, trade on average at around 6 809 €/m², above the municipal price across all property types. Location, the view over the ranges, the plot and energy performance widen the gaps. These figures come from the DVF database (the French record of notarised property sales), which lists the transactions actually registered with notaries.

The Groisy market is driven by its position between Annecy and Geneva, two very dynamic employment areas. With around twenty sales a year, the municipality sees steady activity, fed by a population that has more than doubled since the 1980s to reach 4 082 inhabitants in 2023 according to INSEE. The service from Groisy-Thorens-La Caille station and from the Genevois motorway sustains strong demand from families and cross-border workers, whose purchasing power keeps lasting pressure on prices.
Groisy's values sit in the upper part of the area, close to those of Annecy and above municipalities such as La Roche-sur-Foron. The predominance of detached houses and the scarcity of buildable land explain high prices, particularly on houses and villas with a plot. New supply remains constrained by planning rules, which shifts part of the activity towards resale and renovation. Energy performance weighs more and more in negotiations, especially on the oldest detached homes.
On the corridor between Annecy and the Genevois, Groisy shows a high price level, close to that of Annecy, above its neighbour Cruseilles, and clearly higher than a municipality such as La Roche-sur-Foron.
The medieval past of Groisy can be read in its castles. The château de Soirié is mentioned as early as 1007, that of Boisy in 1314. The de Sales de Thorens family kept possession of the château de Boisy until the Revolution. It was there that, in 1552, Françoise de Sionnaz was born, the future mother of Saint Francis de Sales: she gave birth to the saintly bishop of Geneva while still a teenager, at fifteen. This lineage ties the history of Groisy to one of the great religious figures of Savoy, whose memory durably marks the country of Thorens and the Bornes.
Parish life is recorded far back. The building of a first church in 1410, dedicated to Saint Eucherius, confirms the antiquity of the community. The building went through several states: its bell tower, rebuilt in 1766, was destroyed by fire, and the church took its present form in 1923 with the raising of its tower. The municipality covers a wide territory of around 2 144 hectares of gentle hills, mixing orchards, meadows and forests, a rural geography that long underpinned a farming economy before the recent residential growth.
Groisy has changed scale in a single generation. The population, around 1 659 inhabitants at the start of the 1980s, has more than doubled to reach 4 082 inhabitants in 2023, driven by its position between the employment areas of Annecy and Geneva. The municipality is served by Groisy-Thorens-La Caille station, on the line linking Annecy to La Roche-sur-Foron, and by the Genevois motorway corridor. This growth translated into many detached-house builds, which explain the residential character of part of the territory today.
According to INSEE, Groisy has 4 082 inhabitants, a population that has more than doubled since the 1980s. The stock is dominated by houses, a little over 61 % of dwellings, against close to 39 % apartments, mostly recent. Main residences account for close to 92 % of the stock and second homes about 4 %, the municipality clearly being lived in year-round. More than seven households in ten are owner-occupiers according to INSEE. The market is aimed in large part at families and workers employed in Annecy, in the Geneva area or in neighbouring Switzerland, drawn by a setting of hills and by houses with a plot, whose prices reflect the strong pressure in the area.
The average price recorded is 5 059 €/m², calculated from transactions registered with notaries and published in the DVF database. Houses and villas, in the majority in the municipality, sit on average higher, at around 6 809 €/m². Location, view, plot size and energy performance explain most of the gaps. A reliable valuation rests on recent comparable sales, not on the municipal average alone.
Groisy is a municipality of hills where detached houses dominate the stock, at a little over 61 % of dwellings according to INSEE. Houses and villas, often with a plot and a view over the ranges, trade on average at around 6 809 €/m², above the municipal price across all property types, which also takes in apartments that are more affordable per square metre. The scarcity of buildable land in this tight area widens the gap.
Groisy lies about thirteen kilometres north of Annecy and on the corridor leading towards Geneva. The municipality has Groisy-Thorens-La Caille station, on the Annecy-La Roche-sur-Foron line, and the Genevois motorway quickly links the two employment areas. This twofold rail and motorway service explains much of the municipality's residential appeal to workers from both centres.
The market is aimed mainly at families and workers employed in Annecy, in the Geneva conurbation or in neighbouring Switzerland. Main residences account for close to 92 % of the stock according to INSEE, a sign of buyers settling for the long term rather than for leisure use. Demand focuses first on houses with a plot, rarer and dearer, which pulls the price level upwards for a municipality of this size.
As for any municipality, the natural hazard disclosure should be consulted before purchase, along with the local planning document and the easements specific to the plot. In an area where land is sought after, it is worth checking whether a plot can be built on and the local planning rules. For older houses, energy performance deserves particular attention, as it weighs more and more in negotiations.
