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 We do not publish total vacancy from the same file: its national level varies by a third from one year to the next without the housing stock having changed, which rules out any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.

In 2024, the overall property tax rate on built properties is 10.20% in Acoua.
| Rate voted by the commune | 6.46% |
|---|---|
| Intercommunal body, syndicates and special taxes | 3.74% |
| Overall rate on built properties (total) | 10.20% |
| Household waste collection tax (TEOM) | 19.90% |
| Overall rate on undeveloped land | 3.41% |
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 Acoua, its property tax (taxe foncière) is €1,500 × 10.20% = €153 a year.
On top of this comes the household waste collection tax (TEOM), calculated on the same base: €1,500 × 19.90% = €298. 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.
| Year | Communal rate | Overall rate on built properties | Household waste |
|---|---|---|---|
| 2021 | 6.46% | 9.57% | 19.90% |
| 2022 | 6.46% | 9.54% | 19.90% |
| 2023 | 6.46% | 10.03% | 19.90% |
| 2024 | 6.46% | 10.20% | 19.90% |
Between 2021 and 2024, the overall rate changed by +0.63 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.

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.

Of the 43 passenger cars registered in the commune in 2024:
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.

The risks identified by the State in the territory of Acoua, what they mean, and what they change for a property.
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.

The commune is covered by a prevention plan for: flooding, ground movement. 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.

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.
