The districts move in contrasting ways. Tresin gains 23 % over five years and La Plaine 15 %, starting from the lowest price in the town. Le Braconnais and Gouilloux are stable, and the town centre falls back 5 %. For a seller, this means that the quality of the property and of the building makes the difference in a market where supply is plentiful, with 13,4 % of homes vacant. For a buyer, it means that low prices leave room to finance a renovation, provided its cost is assessed precisely.
Oyonnax compared with the major French cities, on the average price per m² for an apartment.
Oyonnax is the second town of the Ain department, in a valley of the Jura, at an altitude of around 500 metres. Its history is that of an industry that has reinvented itself several times. From the end of the eighteenth century the town made combs, first in wood and then in horn; celluloid arrived in 1880, and in 1889 a workers' cooperative founded the Oyonnaxienne factory.
When the fashion for short hair pushed combs into decline after 1918, some of the manufacturers turned to eyewear, specialising in acetate frames. The materials changed with the century, from galalith to polystyrene, and Oyonnax became the capital of what is now called the Plastics Vallée, with a European plastics centre, the Pôle européen de plasturgie, created in 1989.
The town also keeps the memory of the parade of the Resistance fighters of the Ain, the maquisards, through its streets on 11 November 1943. After the war, to house the workers of its industry, it built from the mid-1950s the La Plaine and La Forge housing estates, to the west of the centre. Today 71 % of homes in the municipality are apartments and 40,5 % of households rent social housing.
In 1973 Oyonnax joined with the villages of Veyziat and Bouvent, on the ridge overlooking the town, before a full merger in 2015. Since the agreement signed in April 2020, the La Plaine district has been the subject of an urban renewal programme.
Oyonnax sells at 1 408 €/m² for an apartment, a level that makes home ownership possible on modest budgets, in a town where 60,7 % of households rent. The buyer profile is that of first-time buyers and families linked to industrial employment in the Plastics Vallée, investors drawn by rental yield, and cross-border workers looking for a lower price than in the Pays de Gex, with Genève (Geneva) some sixty kilometres away. Three points are worth knowing before buying. The first is the geography of prices: the town centre is 13 % below the average, while the northern and eastern areas, Tresin, Gouilloux and Le Braconnais, are above it. The second is the gap with houses, 45 %: in a town of apartment blocks, the house is the rare product. The third is vacancy, 13,4 % of homes in the municipality: the condition of the building, the service charges and the energy performance decide the real value of an apartment far more than its address.
The average price in Oyonnax is 1 408 €/m² for an apartment (actual DVF transactions, notarised sales), within a range of 1 075 to 1 683 €/m² depending on the district. Property portals show asking prices, 10 to 20 % above the prices actually recorded.
Tresin, in the north of the town, at 1 664 €/m², 18 % above the town-wide average. Gouilloux, to the east, follows at 1 532 €/m², then Le Braconnais at 1 514 €/m². All three areas are above the town centre.
At 1 227 €/m², it is 13 % below the town-wide average. The centre concentrates old buildings of an industrial town, often without a lift and in need of renovation, in a municipality where 13,4 % of homes are vacant. The residential areas of the north and east draw more buyers.
No, that is Morez, in the Jura. Oyonnax is the town of the comb and then of plastics processing, the capital of the Plastics Vallée. Some of its comb manufacturers turned to eyewear after 1918, specialising in acetate frames.
Yes: the average apartment price went from 1 309 €/m² in 2021 to 1 408 in 2026, around 8 %, with a rise of 7,1 % over twelve months. Tresin rises the most, by 23 % over five years, while the town centre falls back 5 %.
It is large: houses trade at 2 045 €/m², 45 % more than apartments at 1 408 €/m². In a town where 71 % of homes are apartments, houses are rare, and a large share of them are on the heights and in the associated villages of Veyziat and Bouvent.
