Selling a mill in southern Finistère
The rivers and estuaries of southern Finistère are lined with mills that have become homes. Their charm comes from the water; so does their sale: water rights, obligations on the structures, flood risk. This page brings together what an owner must check before selling, and the market figures for large houses in the inland towns.
Water rights
A mill predating 1789, or authorised since, in principle holds a right to use the water, either historic or regulated. This right has value, in particular for a small hydro-electric project, but it must be proven: old deeds, maps, water regulations. Gather these documents before the sale; the informed buyer will ask for them.
Ecological continuity and structures
On classified watercourses, the owner of a weir or dam may be required to ensure the passage of fish and sediment: fish pass, sluice management, sometimes removal. These obligations, their cost and the available aid must be known before setting the price. Enquire with the French biodiversity office and the river-basin authority.
Flooding and risk statement
A mill is by nature in a flood zone. The risk statement handed to the buyer mentions any prevention plan and compensated claims. Past floods, levels reached and protection works carried out are part of the file; concealing them exposes the seller.
Who buys a mill
Lovers of singular places, often from cities, people with holiday-let or guest-house projects, a few hydro-electric enthusiasts, foreign buyers. A preserved mechanism, a maintained millrace and land on both sides of the water are arguments; a dry, well-heated house even more so.

Questions
How much is a renovated mill worth in Brittany?
It compares with sales of large houses in its town, published above, adjusted for its particular features: proven water rights, condition of the structures, flood exposure, quality of the renovation. The precise value is established after a visit.
Do water rights pass with the mill?
Yes, they attach to the mill and pass with it, provided they still exist: a historic right is lost if the structures have been ruined or the use abandoned. Hence the importance of documenting it.
Must past floods be declared?
Yes. Claims compensated under the natural-disaster scheme must be declared in the risk statement, and any known flood falls under the seller’s duty to inform.
