La Plaine was born of the industrial growth of Oyonnax after the war. From the mid-1950s the town built the La Plaine and La Forge housing estates to the west of the centre to house the workers of its factories, a new town set alongside the old one.
The area is today the priority urban neighbourhood "La Plaine - La Forge - Guynemer", which has 5 167 inhabitants since its boundary was extended to the Guynemer sector in 2024. An urban renewal agreement was signed in April 2020 with ANRU, the national urban renewal agency, and the social landlords, for a programme of around 86 million euros according to the town.
The district is organised around the rue Courteline, the rue Beaumarchais, the rue Corneille, the rue Normandie-Niémen and, on the Forge side, the route de la Forge and the avenue Jean-Moulin.
La Plaine sits at 1 086 €/m², the most affordable price in Oyonnax, 23 % below the town-wide average, with seventeen apartment sales a year. It gains 15 % over five years and 3,6 % over twelve months.

Three points to examine. The urban renewal programme is transforming the district through refurbishments and demolitions: it is useful to know what is planned around the target address. The condition of the building, its service charges and the works already voted are decisive. Finally, the energy performance of buildings of this generation determines whether a flat can be let and what it will fetch on resale.
