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.

Energy performance of the housing stock

Breakdown of homes in Sardieu by energy performance certificate (EPC) band. Since the loi Climat & Résilience (Climate and Resilience Act), it is this band that determines whether a home may be let.

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

Sardieu has 510 dwellings at the 2023 census, of which 91.3% are main residences; the rest is split between second homes and vacant dwellings.

Between 2012 and 2023, the housing stock grew by +19.0% while the population changed by +13.6%: homes are being built faster than the commune gains residents, a sign of smaller households, second homes or rising vacancy.

Long-term empty dwellings

Private dwellings vacant for more than two years (2025)17
Share of private housing stock3.4%

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 Sardieu, a household has 2.56 people on average, compared with 2.17 in France: more families, so demand leans more towards larger homes.

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.

Local taxation

In 2024, the overall property tax rate on built properties is 35.07% in Sardieu.

Rate voted by the commune33.85%
Intercommunal body, syndicates and special taxes1.22%
Overall rate on built properties (total)35.07%
Household waste collection tax (TEOM)14.96%
Overall rate on undeveloped land99.66%
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 Sardieu, its property tax (taxe foncière) is €1,500 × 35.07% = €526 a year.

On top of this comes the household waste collection tax (TEOM), calculated on the same base: €1,500 × 14.96% = €224. 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.

202333.52%34.41%14.96%
202433.85%35.07%14.96%

Between 2021 and 2024, the overall rate changed by +0.99 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.

Natural and technological risks

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

Clay shrink-swell

Low exposurelevel 1 out of 3

Clay soil swells when wet and shrinks when it dries. These movements crack houses with shallow foundations, especially after a drought.

For a property: At this level, no soil survey is required by law.

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

Low potentiallevel 1 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, no particular information is required when selling or letting.

Classified installations (ICPE)

2in 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.
