Putting rental accommodation on your land: the French rules

The short answer first. On ordinary private land in France, you cannot freely place a unit intended for rental. Three routes exist. Installation of under three months, exempt from planning formalities. A prior declaration, for a lasting installation of small floor area. And land already classified as a campsite, holiday village or leisure residential park, the only place where a mobile home may legally sit.

That is the summary. Here is why it gets subtler.

The first thing the law looks at: can it still be towed?

French planning law sorts these objects by mobility, not by appearance. A caravan, under article R.111-47, keeps its means of mobility and complies with road traffic rules. It may sit on private land without formalities as long as occupation stays under three months a year. Take the wheels off, pour a slab, and you fall into another category entirely.

The résidence mobile de loisirs, the mobile home in everyday language, falls under article R.111-41. It keeps its means of mobility but may only be installed on the sites listed in article R.111-42: properly created campsites, leisure residential parks, and holiday villages classified for light accommodation. Anywhere else, it is prohibited. Plenty of project owners discover this after signing a purchase order.

The habitation légère de loisirs is demountable and transportable without being road legal. Outside dedicated sites, it falls back under ordinary building law.

The three-month rule, the real window

Article R.421-5 exempts from formalities any structure installed for a period not exceeding three months. That stretches to one year when the installation supports a cultural, commercial, tourist or sporting event. This is the regime that makes festival accommodation, ski seasons and summer deployments possible.

Two limits. The exemption does not apply in classified sites, remarkable heritage areas or the surroundings of historic monuments. And administrative courts look at actual use, not just whether something can be dismantled: an installation returning to the same spot every year eventually looks like disguised permanence.

Farmland is more closed than people assume

French administrative case law refuses to treat tourist accommodation as a structure necessary for farming. Declared farm camping is capped at six pitches or twenty people, and permits neither mobile homes nor light leisure dwellings. In coastal zones, the continuity of urbanisation principle closes the door further.

A derogation has existed since the law of 16 June 2025 for converting farm buildings disused for over twenty years. It targets existing buildings, not placed modules.

The threshold that changes everything: fifteen people

Accommodation with sleeping quarters becomes a type O public building as soon as fifteen people are hosted. Below that, you stay outside the heavier safety regime, with minimum fire safety obligations. Five two-person units keep you under. A sixth tips you over, safety commission included. Worth building into the operating plan from the first box rather than at expansion time.

On tax, unclassified accommodation attracts a proportional tourist tax, between 1 and 5 % of the nightly rate per person depending on the local authority. Classification as a meublé de tourisme switches you to a fixed rate, often more favourable.

Where to start

Before any quote, before any purchase: your municipality's local plan, then a meeting at the town hall with your plot map. It is free, it takes an hour, and it saves you from buying a unit you cannot place. The departmental land authority settles borderline cases, and its reading varies from one department to the next. Better to know beforehand.

At Hotel Inbox, land feasibility always comes before the commercial proposal. A box sold for a spot where it cannot stay serves nobody, us included.
