Property in Collex-Bossy: a rural municipality with listed heritage

The property market in Collex-Bossy.

Collex-Bossy borders Versoix, Bellevue and the French municipality of Ferney-Voltaire, on the right bank of Lake Geneva. A rural municipality with a strong agricultural character, it covers 6.89 km², with one of the lowest densities in the canton, at 242 to 248 inhabitants per km².

The recorded sale price is 12’997 CHF/m², with rents at 30 CHF/m² per month. Over the recent period, 44 properties were marketed, split equally between sales and rentals, with 22 transactions in each category.

This balanced split, on a limited volume of transactions, reflects a niche market typical of a sparsely populated rural municipality, where the supply of available properties remains limited by nature.

Living in Collex-Bossy

The territory came under Savoy rule in 1353, then under Geneva in 1589, before being annexed to France by the Treaty of Lyon in 1601. Ceded to Geneva by the Treaty of Paris of 1815, the municipality split into two separate entities, Bellevue and Collex-Bossy, in 1855, following socio-economic and religious rivalries. The villages of Collex, Bossy, Vireloup and Crest-d’El are today recognised by the ISOS inventory as characteristic built settlements.

A historic village dating back to the early Middle Ages, Bossy is home to the Chapelle de la Persécution and the municipal water tower, built in 1966.

Sales market dynamics

The balance between properties sold and properties let, on a limited volume of transactions, points to a niche market where each transaction remains significant. This structural scarcity, typical of a rural and sparsely populated municipality, tends to support prices in the sales segment.

Municipal taxation

The municipal additional tax rate (centimes additionnels) is 39 centimes for 2026, unchanged since 2025. This rate places Collex-Bossy among the least taxed municipalities in the canton, in 14th place, below the cantonal average of 41.4 centimes.

The stages of a sale

The high-end segment remains particularly active in the municipality. A property priced correctly from the moment it goes on the market generally finds a buyer more quickly than one repriced after several weeks.
