Buying a mill for sale in Auvergne-Rhône-Alpes means choosing one of France's richest regions for hydraulic heritage: from the gorges of the Ardèche to the alpine valleys of the Arve and the Fier, via the volcanic rivers of Cantal and the torrents of Drôme, almost every department has its former watermills, flour mills and millers' houses. On this page, ma-propriete.fr brings together mills for sale across the region's twelve departments.
You will also find price benchmarks based on actual sales, an overview of the areas where these properties are concentrated, and the specific points to check before buying a mill in the mountains or in a valley, whether you are drawn to a lakeside setting near Annecy or a quieter hamlet in the Cantal. To prepare your project, our white paper on setting up a rural gîte covers the steps useful for restoring an old building.
There are no official statistics dedicated to mills: sales are too rare and too varied (a ruin to restore, a habitable mill, a flour mill with a turbine). The most reliable market benchmark remains the price of country houses, which a habitable mill resembles, with a premium for the water, the character and the water rights, and a discount for the work required.
How much does a country house cost in Auvergne-Rhône-Alpes? According to DVF data (notarised sales) analysed by the ma-propriete.fr observatory, the median price of a country house in Auvergne-Rhône-Alpes stood at €230,000 in 2025, with an average price of €246,927 and a median price of €2,200/m² of living space (16,528 house sales in rural municipalities over the year). 10% of houses sold for less than €98,000 (floor price, 1st decile) and 10% for more than €410,000 (ceiling price, 9th decile). The typical country house offers 109 m² of living space on an average plot of 3,243 m², i.e. around 0.3 ha.
The region is well above the national median (€189,200). Since the second half of 2020, the regional median price has risen from €200,000 to €230,000, i.e. +15.0%; over one year (2024-2025) the change is +3.1%.

A regional average also hides large gaps between municipalities. A smallholding to renovate, a restored longère with its outbuildings, a farmhouse on several hectares of land or a manor house with parkland do not sell at the same price, and the location matters as much as the building: coastline, tourist area, peri-urban countryside close to a job market or deep countryside. The table below shows the median price of country houses in Auvergne-Rhône-Alpes by type of municipality (cumulative sales from mid-2020 to 2025) and its change between 2021 and 2025.
| Type of municipality | Median price 2020-2025 | Median price per m² | Change 2021-2025 | Sales 2020-2025 |
|---|---|---|---|---|
| Tourist coastline | €140,000 | €1,515/m² | +9.5% | 269 |
| Residential coastline | €426,400 | €3,914/m² | +4.6% | 890 |
| Inland tourist areas (hinterland, mountains) | €183,000 | €1,911/m² | +9.0% | 12,653 |
| Peri-urban countryside (city catchment area) | €245,000 | €2,318/m² | +4.9% | 51,949 |
| Deep countryside (outside urban influence) | €195,000 | €1,893/m² | +9.0% | 34,988 |
Note: in Auvergne-Rhône-Alpes, the municipalities classified as "coastline" have no access to the sea. They are municipalities bordering lakes of more than 1,000 hectares (or, in Eure, the Seine estuary) covered by the 1986 Loi Littoral, which also applies to such inland lakes and estuaries.
These benchmarks help you assess a listing, estimate a property before putting it up for sale, or set your budget, whether you are looking for a holiday home, a permanent move to the French countryside or a property to turn into a rural gîte.

The region has an exceptional river network: the Allier and its tributaries in Haute-Loire and Cantal, the Loire rising on Mont Mézenc, the Rhône and the Ain with its gorges, the Isère and the Drac around Grenoble, the Drôme and the Ardèche with their steep valleys, and the Arve, the Arly and the Fier in Savoie and Haute-Savoie. This network powered generations of grain watermills, as well as textile mills in Ardèche and Drôme and hydraulic sawmills in mountain areas.
Windmills, by contrast, are almost absent from the regional landscape: only a few isolated examples exist on the windy plateaux of Puy-de-Dôme or Drôme provençale. Most of the supply therefore consists of watermills, across a wide range of altitudes and landscapes, from the Bourbonnais hedgerow country to the Savoyard mountain pastures. Some former oil mills, once used for walnut or hemp seed in the Dauphiné and Vivarais, add further variety to this hydraulic heritage.
In Ain (01), mills are spread along the Bresse plain and the Ain gorges, between Bourg-en-Bresse and Nantua. Allier (03) keeps rural buildings typical of the Bourbonnais around Moulins and Vichy. Ardèche (07) offers the most spectacular landscapes, between gorges and former silk mills near Aubenas and Vallon-Pont-d'Arc. Cantal (15) and Haute-Loire (43), on volcanic ground, keep basalt mills along the Alagnon and the young Loire. Drôme (26) combines cool valleys with a drier Drôme provençale. Isère (38) and Loire (42) hold significant textile-industry heritage. Puy-de-Dôme (63) and Rhône (69) offer properties close to Clermont-Ferrand and Lyon. Savoie (73) and Haute-Savoie (74) hold a handful of rare and sought-after alpine mills, in the Tarentaise, Maurienne and Chablais valleys.
Areas near Lyon, Grenoble or Annecy sell noticeably above the regional average, while Cantal, Haute-Loire and Allier remain more affordable territories for a mill to renovate. The Ardèche gorges and the Chartreuse foothills sit in between, combining strong scenic appeal with prices that still vary widely from one hamlet to the next.
A mill in Auvergne-Rhône-Alpes is bought together with its water: check the water rights (a mill fondé en titre or holding an authorisation), the condition of the millrace, sluice gates and weir, and the ecological-continuity obligations, closely monitored on classified rivers such as the Ardèche or the Drôme. A hydroelectric project using a turbine or micro-plant requires a prior technical and administrative study.
In the mountains, flash floods, flood zoning and exposure to avalanches or land movement are decisive factors, as is winter access. Outbuildings (barn, drying room, miller's house) often make it possible to plan a gîte, an activity for which this region, popular with tourists in both summer and winter, offers a favourable setting.
