L'accession à la propriété souvent impossible dans la Métropole de Lyon, en Haute-Savoie et dans le Genevois français

The report titled « L’accession à la propriété souvent impossible dans la Métropole de Lyon, en Haute‑Savoie et dans le Genevois français » is an Insee analysis authored by Timothée Barnouin, Sandrine Chaumeron, Aline Labosse and Florence Léger. Insee, France’s national statistics institute, produces authoritative demographic and housing data, and the authors are senior researchers specialised in regional housing markets. The study offers a pre‑COVID‑19 snapshot (2019) of households’ capacity to purchase a home across Auvergne‑Rhône‑Alpes, with a focus on the most price‑constrained zones.

In 2019, two‑thirds of tenant households (≈ 66 %) could theoretically afford a home in the area where they lived, provided they met income and savings criteria. The ability to buy varies sharply by household type: eight‑in‑ten childless couples could purchase, whereas only 63 % of single persons and 50 % of couples with one child could do so. Families with two or three children face the greatest barriers, with less than half able to buy in many parts of the region.

The analysis identifies property price as the dominant obstacle to home ownership, outweighing disposable income. Median prices reach €4 300 / m² for houses in the Lyon metropolitan area, compared with €2 300 / m² for the wider region. In the Genevois, Grand Annecy and the Pays de Gex, median prices range from €3 800 to €4 100 / m², rendering purchase impossible for most households except childless couples. In contrast, more affordable zones such as the Vercors, Ardèche gorges and parts of the Dombes show lower price pressures.

Within the Lyon metropolis, intra‑urban variation is stark: over half of households cannot buy in the city centre, while the eastern and southern suburbs present slightly better affordability. The study notes that in the north‑west Lyon area and the affluent suburbs of Monts d’Or, only one‑third of families could afford a home. Peripheral zones such as Villeurbanne and the Grand Annecy area are marginally more accessible, with roughly half of families able to purchase.

Alpine districts, including the High‑Alps, parts of Ardèche and the Drôme, as well as tourist‑driven communes like Chamonix‑Mont‑Blanc and the Tarentaise valley, exhibit high price‑to‑income ratios. In the Haute‑Savoie, 21 % of secondary residences are owned by foreign residents, further tightening supply. In the CC du Haut‑Chablais, median prices hit €4 900 / m², and in many ski resorts, more than half of new apartments sell above €5 800 / m².

The report highlights that apartments are generally more affordable than houses. While the median price for a house is €205 000, an apartment averages €140 000. For new construction, about 50 % of apartments sell above €4 000 / m², with the Lyon metropolis reaching €4 700 / m². In less pressured markets such as Saint‑Étienne, new apartments are priced around €2 900 / m².

The findings underscore the challenge of achieving sustainable, inclusive housing in high‑price zones. Limited affordability restricts the ability of families, particularly larger ones, to transition from renting to owning, potentially increasing reliance on the rental market and affecting long‑term housing stability. Policymakers aiming to promote sustainable neighbourhoods must consider price‑moderating measures—such as increasing affordable housing supply, regulating secondary‑home ownership, and supporting targeted financing for families with children—to bridge the gap identified by the Insee study.
