Property tax in Chambéry in 2026: the most heavily taxed town in its conurbation

1. What is the property tax rate in Chambéry in 2026 ?

A Chambéry notice reads in four lines, only one of which really weighs.

The calculation fits in one line. Your property tax on built property equals the cadastral rental value of your home divided by two, multiplied by the overall rate of 46,48 %. The waste collection line applies to the same base, at a rate of 8,28 %.

The cadastral rental value is not the rent you could ask today. It is an administrative value inherited from a 1970 classification, revalued every year by a national coefficient. It reflects neither the market price of your home nor the gap between Les Hauts de Chambéry and Chambéry-le-Vieux.

2. Why does Chambéry tax more than its neighbours ?

The table below compares the main municipalities of the conurbation. Only the first column really changes : the rest is identical everywhere.

That gap is in no way a Chambéry anomaly. It comes from the fact that a central town carries, for a whole catchment area, facilities that its own residents are not alone in using : theatre, music school, museums, swimming pools, main roads, street cleaning, municipal police. Those so-called centrality costs fall on a body of municipal taxpayers that is smaller, proportionally, than the population served.

The structure of the housing stock in Chambéry sharpens the effect. Only 39,7 % of households are owner-occupiers, against 58,4 % tenants, of whom 25,5 % in social housing (INSEE, the French national statistics institute, 2023 census). The base of property tax payers is therefore narrow compared with the costs carried.

3. Has the rate risen in recent years ?

On top of those rate rises comes the national mechanism, which works every year without any local councillor voting anything. The flat-rate revaluation coefficient for cadastral rental values is indexed to the November harmonised index of consumer prices : +7,1 % in 2023, +3,9 % in 2024, +1,7 % in 2025 and +0,8 % in 2026. Taken together, that indexation alone represents close to 14 % growth in the bases over four years.

Politically, the line should hold. Thierry Repentin was re-elected mayor in the second round on 22 March 2026 with 45,22 % of the votes cast, ahead of Vincent Patey (43,83 %) and Brice Bernard (10,95 %), a gap of only 259 votes. The majority holds 33 seats, the right-wing opposition ten and the Rassemblement national two, on a turnout of 52,69 %.

4. How much do you pay depending on your district ?

The four profiles below are reconstructed from real districts of Chambéry and from order-of-magnitude rental values. They do not replace your notice, which alone is authoritative. The last column sets the annual charge against the market value of the home, calculated with the prices per m² from actually recorded transactions.

Four typical profiles in Chambéry

These profiles rest on districts with contrasting prices : 2 124 €/m² at Les Hauts de Chambéry, 2 790 €/m² at Le Biollay, 3 130 €/m² in the town centre, 3 466 €/m² at Chantemerle and up to 3 657 €/m² at Chambéry-le-Vieux, for a town-wide average of 2 981 €/m² for an apartment and 3 931 €/m² for a house in 2026 (DVF data, the French notarised sales database, processed by Immover, 2024-2025 transactions). The detail is on our page on property prices in Chambéry.

6. And if your home is a second home ?

The decision is in no way automatic : the surcharge is voted each year by resolution of the town council, between 5 % and 60 %, before 1 October for application the following year. Chambéry has chosen the ceiling, like Annecy, Lyon and Grenoble. Conversely, Aix-les-Bains, though also in a tight area and far richer in second homes, applies no surcharge.

The Chambéry paradox is worth stating : the town taxes at the maximum a category of housing that accounts for only 1 229 units, that is 3,6 % of its stock of 33 867 homes. The budgetary yield is therefore limited. The measure is more a signal about how the housing stock is used than a structural source of revenue, in a town that also counts 3 057 vacant homes, that is 9,0 % of the total.

7. Chambéry against the other towns of the alpine corridor

That reversal is explained by the base rather than by management. A municipality whose housing stock is recent, large and well classified in the land register has higher revenue at an equal rate : it can therefore show a lower rate for the same yield. Annecy, a new municipality formed from six mergers and driven by strong construction activity, is the illustration ; Grenoble, at the other extreme, offsets an older stock and a constrained base with a record rate.

A high rate applied to modest rental values does not necessarily produce a bigger bill than a town with a low rate and high values. The final amount comes down to the product of the two, and that is exactly why the table of profiles above says more than the ranking of rates.

8. What impact on the value of your property ?

Three observations to place the real effect of taxation on your property.

1. The Chambéry market has picked up again. After a fall to 2 933 €/m² in 2024, prices rose to 3 024 €/m² in 2025 then settled at around 2 981 €/m². On a volume of around 716 apartment transactions a year, it is a liquid market, where the order of magnitude is reliable.

2. The property tax is a cost of ownership, not a discount on the price. It does not cut the advertised value : it reduces an investor's net yield and the purchasing power of a buyer who thinks in terms of a total monthly payment. On a 3-room flat in the centre, it represents the equivalent of about a month and a half of rent a year, a contained level.

3. The energy performance rating weighs more than the rate. In Chambéry, 5,9 % of the homes assessed are rated F or G, and 13,4 % E (ADEME database, 20 157 assessments). In a mountain town where heating is a real expense, the energy label is now negotiated harder than the aspect or the storey. That is where the difference lies between a property that sells and one that sits, far more than eleven points of municipal rate.
