Posting workers to France: requirements, obligations and accommodation (2026 guide)

Sending a team to a work site or project in France? Here, in plain words, are the steps to take before arrival and the rules for accommodating your posted workers. And a local partner who handles the housing with you, from day one until the end of the project.

1 · Before the first day in France

The posting formalities

They apply to any company based outside France that temporarily sends its employees to work in France. Nothing complicated if you plan ahead and have the right contact on site.

1

Posting declaration (SIPSI)

Mandatory

Mandatory for a provision of services in France, such as a work site, except for exemptions set by law (posting on the company's own account, certain short activities). In French, on the SIPSI online service: your company, each posted worker, the place and length of the assignment, working hours and accommodation. Your client in France must check that it has been filed.

When: before the posting startsWhere: sipsi.travail.gouv.fr
Good to know: without a declaration, the fine can reach €4,000 per worker.
2

Representative in France

Mandatory

A person in France, named in the SIPSI declaration, liaises with the labour inspectorate and keeps the documents available for the whole assignment. Exemptions exist, notably for posting on the company's own account.

When: in the SIPSI declarationWhere: sipsi.travail.gouv.fr
Good to know: it can be a team member or a service provider in France.
3

A1 form

Social security

Under EU social security coordination rules, it certifies that your workers remain covered by your country's social security. Request it from the competent institution before departure and keep a copy on site. It does not replace the SIPSI declaration.

When: before departureWhere: your social security institution
Good to know: without an A1, contributions may be claimed in France.
4

BTP card

Construction sites

Mandatory ID card for every worker on a building or civil engineering site in France, posted workers included. The employer orders it online.

When: before arriving on siteWhere: cartebtp.fr
Good to know: the card is checked on construction sites.
2 · Accommodating the team

Housing posted workers: the basic rules

When several workers share the same accommodation, French law calls it collective accommodation: depending on the situation, it must be declared and meet comfort rules. A good housing partner helps you see clearly and avoid needless fines.

French Labour Code standards for worker accommodation

They apply to premises used to accommodate workers. Whether they apply depends on the actual situation and on how the accommodation is provided.

6 m²minimum floor area per person
6 maxpeople per bedroom
Separatebedrooms for men and women
80 cmminimum between two beds
0bunk beds: a real bed for each person
18 °Cminimum, aired and heated rooms
Extracts from the French Labour Code (articles R. 4228-26 et seq.).

The collective accommodation declaration

A form (Cerfa no. 61-2091) sent to the prefecture and the labour inspectorate within 30 days of moving in. For posted workers, it comes in addition to the address given in the SIPSI declaration.

We prepare this file with you and give you all the information about the accommodation. We already help foreign companies with this step.
3 · Choosing where to house the team

Airbnb, Booking… or a partner dedicated to professionals?

Short-term rental platforms are designed for holidaymakers. For a team staying several weeks on a work site, a few differences really matter.

“We housed around thirty people near Amiens and in Troyes for several months on two different sites. SISAID LMP, through its Tinubia network, made housing easy for us and helped us with the declarations to the DREETS in both regions.”

Frequently asked questions

Posting and accommodation: your questions

Can we house a work crew in an Airbnb or through Booking?

For a few nights, yes, but it rarely suits a project lasting several weeks: the home may not be free when you need to extend, hosts don't know what professionals need, and the team sometimes has to move mid-assignment. A dedicated partner reserves the home for the whole project.

Must the accommodation address appear in the SIPSI declaration?

Yes, the posting declaration includes information about the workers' accommodation. We send you the address and details of the home as soon as you book, so you can file your declaration before arrival.

Do we have to declare the accommodation if we rent an apartment for our team?

Generally yes, if several workers share it: it is collective accommodation, to be declared to the prefecture and the labour inspectorate within 30 days (Cerfa no. 61-2091). We help you prepare the file.

How many workers can share a bedroom?

Six people at most per bedroom, with at least 6 m² per person, separate bedrooms for men and women and at least 80 cm between beds. Bunk beds are not allowed in collective accommodation.

Can you house us for the whole project, even if it changes?

Yes. The home is reserved for your team for the whole planned period, and we handle extensions without making you change homes.

Which languages do you work in?

We work in English and French, by email, phone or WhatsApp, 7 days a week. This guide is available in 11 languages for your teams and your administrative staff.
