Buying a mill for sale in Yonne (89) means searching between Burgundy and the Puisaye, along calm rivers such as the Yonne, the Serein, the Armançon and the Cure, which powered a large number of watermills for flour, as well as stone grinding and tanning. On this page, ma-propriete.fr brings together the mills for sale in Yonne: a Burgundy limestone watermill to renovate, a former mill on the Serein with its millrace, or a mill house with outbuildings. Some of these mills still keep their mechanism or their limestone millstone, evidence of a milling activity that shaped the rural economy of the Yonne until the 20th century.
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. To prepare your project, read our white paper on setting up a rural gîte, whose advice on outbuildings and financing applies fully to a mill. These varied past uses explain very different states of preservation, some mills having been maintained continuously while others were left derelict.
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.

A departmental average hides large gaps. 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 Yonne (89) by type of municipality (cumulative sales from mid-2020 to 2025) and its change between 2021 and 2025.

|---|---|---|---|---|
| Inland tourist areas (hinterland, mountains) | €115,000 | €1,176/m² | +3.7% | 1,039 |
| Peri-urban countryside (city catchment area) | €147,500 | €1,477/m² | +0.0% | 6,218 |
| Deep countryside (outside urban influence) | €120,000 | €1,250/m² | +3.4% | 4,897 |

The Yonne, between Auxerre and Joigny, and its tributaries the Serein near Chablis and Noyers-sur-Serein, the Armançon near Tonnerre and Aisy, and the Cure near Vézelay and Avallon, once powered many watermills, built in local limestone, some still keeping their wheel or mechanism. Many have been converted into homes while keeping the charm of their millrace.
On the drier plateaus of the Puisaye, west of the department, and the pays d'Othe to the north, watercourses are more discreet and mills scarcer; a few isolated windmills can be found instead, once needed where water was lacking to grind grain. The proximity of Burgundy's wine country adds further appeal to these mills, often sought as a complement to a wine-tourism project. A local architect familiar with Burgundy limestone construction can be a valuable ally throughout this kind of restoration project.
Around Auxerre, the préfecture well connected to Paris via the A6 motorway, mills in the Yonne valley enjoy a reputed wine-growing setting on the doorstep of Chablis. The Vézelay and Avallon area, on the Cure, attracts buyers seeking heritage and cultural tourism. Near Tonnerre and the Armançon, mills benefit from direct access to the Paris-Dijon railway line. The Joigny and Villeneuve-sur-Yonne area, closer to the Paris region, completes this picture with mills well served by the N6 road.
Mills close to Auxerre, Chablis and Vézelay sell well above the departmental average, driven by the area's tourist and wine-growing reputation. The Puisaye, around Saint-Fargeau and Saint-Sauveur-en-Puisaye, and the pays d'Othe remain the most affordable areas for a mill in need of renovation. These price differences mainly reflect proximity to Chablis and the Cure valley rather than the size of the mill itself.
Check the water rights attached to the property (a mill fondé en titre or holding an authorisation), the condition of the millrace, weir and sluice gates, and the ecological-continuity obligations on the Serein and the Armançon, both classified over several stretches. A small hydroelectric turbine project remains possible but requires a thorough prior study. Have the foundations and retaining walls checked where the mill is built directly on the riverbed. Buyers should also allow extra time for technical surveys, given how much these mills can differ from one valley to another. Water-related risks deserve particular attention on this stretch of Burgundy rivers.
The buildings, in Burgundy limestone often under flat tile roofs, deserve a careful check for damp and flood zoning, as the Yonne and its tributaries can rise quickly during winter floods. Outbuildings (barn, shed, miller's house) lend themselves well to a gîte project, a growing activity in this rural department close to Paris. Budget for redoing the rendering and joinery, often needed on these older limestone buildings.
