Living Next to Monaco: Beausoleil, Cap-d'Ail and Roquebrune-Cap-Martin Compared

Homes in Monaco averaged an estimated €57,569 per square meter in 2025, according to IMSEE, the Principality's statistics institute, in an estimate that excludes villas and Monaco-Ville. A few streets away, in the French communes that border it, apartments averaged between about €6,800 and €7,600 per square meter in 2026. For buyers who want to be close to Monaco, that difference explains why Beausoleil, Cap-d'Ail and Roquebrune-Cap-Martin are so often on the shortlist.

The trade-off is not only price. Living across the border means French law, French costs and French taxes, and owning there does not provide Monaco residency. This guide compares the three communes and explains what changes.

The price gap at a glance

The figures come from different sources and dates, so read them as orders of magnitude rather than precise comparisons. The conclusion is clear all the same: for the price of a modest Monaco apartment, a buyer can often find a large apartment, or a house, a few minutes away in France. Our Monaco market report explains how Monaco's own prices vary by district.

The three communes compared

Beausoleil

Beausoleil rises directly above Monte-Carlo, so close that some of its streets continue into Monaco's. It is the most urban of the three, with apartments in Belle Époque and modern buildings, many with views over the Principality and the sea. Daily life is closely tied to Monaco: shops, restaurants and the Casino district are a walk away, though the streets are steep.

It suits buyers who want to be in Monaco every day, on foot, and value an apartment over a garden.

Cap-d'Ail

Cap-d'Ail sits on the western side of Monaco, next to Fontvieille, on a green headland with a coastal path, small beaches and villas among the pines. It combines a residential, seaside feel with immediate access to the Principality, and is the most expensive of the three per square meter in recent data.

It suits buyers who want the sea, a quieter setting and Monaco at the edge of town.

Roquebrune-Cap-Martin

East of Monaco, Roquebrune-Cap-Martin includes a medieval hill village, the Cap Martin peninsula of villas and gardens, and seafront districts such as Carnolès toward Menton. Prices vary widely inside the commune: SeLoger's January 2026 estimates put houses on Cap Martin at €12,677 per square meter and apartments in Cabbé–Saint-Roman at €8,373.

It suits buyers who want more space and a choice between village, peninsula and seafront, a short drive from Monaco.

What changes when you live in France

• French law and process. Purchases follow the French process, with a notaire, a preliminary contract and a 10-day withdrawal period for a non-professional buyer of a home. Our guide to buying property in France as an American explains each step.

• French costs. All three communes are in the Alpes-Maritimes, where transfer taxes on an existing home come to about 5.81% of the price; total acquisition costs commonly reach around 7% to 8%. Monaco has its own, different duties.

• French taxes. Owners pay the taxe foncière and, for a second home, the taxe d'habitation. If you live in the home, French tax-residence rules apply: you are considered resident for tax purposes if your home or main place of stay is in France, among other tests.

• No Monaco residency. Owning or renting a home in Beausoleil, Cap-d'Ail or Roquebrune-Cap-Martin does not give the right to live in Monaco. Monaco residency requires accommodation in the Principality and its own application. Our Monaco residency guide explains the requirements.

These differences make cross-border tax advice essential before you choose where to live, particularly if you plan to work in Monaco or move your tax residence.

How to choose

• Walk or drive? Beausoleil puts Monaco on foot; Cap-d'Ail and Roquebrune-Cap-Martin generally mean a short drive, train or bus, and Monaco's traffic at peak hours.

• Apartment or house? Beausoleil is mostly apartments; Cap-d'Ail and Roquebrune-Cap-Martin offer more villas and gardens.

• Where will you be resident? If tax residence matters to your plans, take advice before choosing between a home in France and one in Monaco.

• Rent or buy first? Renting for a season can show how a commune works day to day before committing.
