Summary written automatically from the figures on this page, comparing the municipality with the median of the municipalities in its département (or of France when the département has too few municipalities with data).

💶 Prices and rents: how they have changed

318 listings observed. These are advertised rents, service charges included: they are higher than the rents of existing leases. The estimation method was revised in 2022: only the 2022 and later editions, which are comparable with each other, are shown. The gross yield compares the annualised rent with the median sale price of flats; it takes no account of service charges, property tax or vacancy.

👥 Household incomes

Tax statistics from the DGFiP: income for 2024, declared the following year. The reference taxable income is an average: very sensitive to high incomes, it is not a substitute for a median income. The incomes are those of the tax households living in the municipality, not only those of co-owners.

🌡 Energy performance of homes (DPE)

Calculated on the DPEs issued for flats each year (56 in 2025), on sales or lettings: they do not cover the whole housing stock and reflect homes that change occupant. The years 2021 (second half only) and the current year, being incomplete, are not shown. The DPE calculation method changed (July 2021 reform), which limits comparison with earlier years. Under France’s Climate and Resilience Act, homes rated G have been banned from letting since 1 January 2025, followed by those rated F from 2028 and E from 2034.

🌊 Natural hazards

Hazards listed for the municipality:

A declaration recognises a state of natural disaster for a given event; it triggers the “natural disasters” cover of home insurance policies and of the building’s insurance. “Drought” declarations relate to the shrinking and swelling of clay soils, a frequent cause of cracks in buildings. A risk statement (état des risques) must in particular be attached to a sale or lease when the property lies in an area covered by a prevention plan, in seismic zone 2 to 5, or with a class 3 radon potential. This page presents municipal data: it does not replace the risk statement drawn up for the property’s address.

🧾 Property tax and local taxation

The overall rate adds the municipal share and the inter-municipal share. The tax due by an owner equals this rate applied to half of the home’s cadastral rental value, reduced where applicable by exemptions.
