Read with caution. These sales are not comparable with one another: poorly rated dwellings are often old and well located, in town centres, which can make them more expensive per square metre than recent dwellings on the outskirts. The gap therefore measures the commune's housing stock, not the "premium" of a good EPC (DPE) for an otherwise identical property.
How to read these figures. The median price splits the market in two: half of sales were made below it, half above. It withstands the few extreme sales that distort a small commune better than the average does.
The data come from DVF, the file of sales actually recorded by notaries, not from advertised prices, which are asking prices rather than agreed ones. Only sales of a flat or a house with a known floor area are counted. DVF does not cover Alsace-Moselle, which is governed by the land register (livre foncier).

How to read this table. This is a predicted advertised rent, including service charges, per square metre per month — not the rent signed in the lease. The range brackets the estimate: most listings in the municipality fall within it. These estimates are recalculated every year with a new model, so two releases cannot be compared with each other.

Why this breakdown matters. A dwelling rated G can no longer be let under a new lease since 1st January 2025; F will follow in 2028 and E in 2034. A commune whose stock is largely rated F or G therefore faces a wall of renovation work, or an exit from the rental market.
Note: these figures cover surveyed homes, not the entire stock. A survey is only required on sale or letting, so homes occupied for a long time are under-represented.
The trend line starts in 2022: the assessment changed its calculation method in July 2021, and earlier labels cannot be compared with later ones. It describes the dwellings assessed during the year (those being sold, let or just renovated), not an annual census of the housing stock.
Housing stock
Nantes has 196,038 dwellings at the 2023 census, of which 89.4% are main residences; the rest is split between second homes and vacant dwellings.
What are dwellings used for?
Main residences89.0%
Second homes and occasional dwellings4.9%

Why vacancy of more than two years. A dwelling that stands empty for a few months is waiting for a buyer, a tenant or the end of building work: that is the normal breathing of the market. Empty for more than two years, it has left the market — a run-down property, a blocked inheritance, an owner who will neither let nor sell. We do not publish total vacancy from the same file: its national level varies by a third from one year to the next without the housing stock having changed, which rules out any comparison.

Why the number of people per household matters. A household is everyone who shares the same dwelling. The fewer people it has, the more demand shifts towards small homes — studios and one-bedroom flats, sought by people living alone, students and retirees; the more it has, the more demand shifts towards family homes with three or more rooms.
In Nantes, a household has 1.87 people on average, compared with 2.17 in France: more people living alone and couples without children, so demand leans more towards small units.

How to read these figures. The standard of living is a household's disposable income (salaries, pensions and benefits, after tax) divided by its number of consumption units: the first adult counts as 1, other people aged 14 or over as 0.5, and each child as 0.3. It allows a single person and a family to be compared.
The poverty rate is the share of residents whose standard of living is below 60% of the national median. INSEE does not publish it for small communes, for reasons of statistical confidentiality: its absence is not a zero.
The unemployment rate here is the census one: people who declare themselves without work and looking for it, among the economically active aged 15 to 64. It is higher than INSEE's quarterly rate, which follows a stricter international definition.

Worked example
A dwelling with a cadastral rental value of €3,000 has a tax base of €1,500: the law sets it at half the rental value. In Nantes, its property tax (taxe foncière) is €1,500 × 53.36% = €800 a year.
On top of this comes the household waste collection tax (TEOM), calculated on the same base: €1,500 × 7.95% = €119. A landlord can recover it from their tenant; the property tax (taxe foncière), by contrast, remains payable by the owner.
These amounts are before the collection charges retained by the State. Your property's rental value is shown on your property tax (taxe foncière) notice.

Between 2021 and 2024, the overall rate changed by +4.44 point.
How to read these rates. Property tax (taxe foncière) is calculated by multiplying the property's tax base by the overall rate: this is the figure to compare between communes, not the communal rate alone. Since 2021, départements no longer collect property tax on buildings; their former share is included in the communal rate.
A high rate does not mean a high tax. The cadastral rental value is not the market rent: it is an administrative estimate based on 1970 rents, revalued each year by a national coefficient. In a town with old, low rental values, a 50% rate can cost less than a 25% rate elsewhere.
Commune subject to the tax on vacant dwellings
Nantes is on the list of communes where the housing market is tight. A dwelling left empty for more than a year is subject to the tax on vacant dwellings there, and the municipal council may raise the housing tax on second homes by 5% to 60%.
The commune has voted a surcharge of 60.0% on the housing tax on second homes.

How to read this list. It shows the services for which at least one establishment is recorded in the commune. A service that does not appear is not necessarily absent: INSEE does not locate every facility with the same precision, and the list only includes the main ones.

What this figure does not say. Each stop is a bus, tram, metro or train stop. Their number shows where the network is dense, not how often services run: a stop served every five minutes counts the same as one served twice a day.

How to read these figures. The pass rate is that of the brevet for a collège and of the baccalauréat for a lycée. The index of social position summarises pupils' social background: the national average is close to 100, and a higher index indicates more advantaged families. Nursery and primary schools are not covered.

Dwellings and premises connectable to fibre95.4%
213,933 connectable out of 224,221
Connectable means that optical fibre reaches the building or the street and a subscription can be taken out, not that the dwelling is already subscribed.

Electric cars
Of the 4,845 passenger cars registered in the commune in 2024:
Electric cars17.2%
Plug-in hybrids6.9%
Why this share may look high. These are cars registered during the year, not all those on the road: electric vehicles weigh far more in recent purchases than in the overall fleet. Company and rental vehicles are also registered at the company's address, which inflates the share in communes that host head offices or rental firms.

Natural and technological risks
The risks identified by the State in the territory of Nantes, what they mean, and what they change for a property.
Seismicity
Moderatelevel 3 out of 5
France is divided into five seismicity zones, from 1 (very low) to 5 (high, in the Antilles).
For a property: From zone 3, new houses must comply with earthquake-resistant building rules. For an older property, no upgrading is required.
Radon potential
Significant potentiallevel 3 out of 3
Radon is a natural radioactive gas that rises from granitic and volcanic soils and can build up in poorly ventilated rooms, especially on ground floors and in basements.
For a property: At this level, the seller or landlord must inform the buyer or tenant. Good ventilation and a sealed ground floor are usually enough to reduce exposure.
Risk prevention plans
3in the commune
The commune is covered by a prevention plan for: flooding. This is a document issued by the prefect that delimits the exposed zones.
For a property: In the delimited zones, building or extending may be prohibited or subject to requirements. The plan does not necessarily cover the whole commune: only the risk statement provided before a sale or letting says whether the address is affected.
Classified installations (ICPE)
157in the commune
A classified installation is an activity that the law subjects to declaration or authorisation because it may cause nuisance: factory, warehouse, livestock farm, petrol station, waste recycling centre, boiler room.
For a property: Their number mainly reflects the commune's economic activity: most pose no danger to neighbours. What matters is their nature and their distance from the property.

A prevention plan is not a bad sign in itself. It shows that the risk is mapped and regulated; it is its absence for a known hazard that should raise questions.
This page describes the commune, not an address. Before a sale or a letting, the seller or landlord must provide a risk statement drawn up for the property. You can obtain one free of charge for any address at georisques.gouv.fr.
