SCI Domiciliation: Which Registered Office Address to Choose in 2026?

A French real estate holding company (SCI) cannot legally exist without an address: the registered office determines how the company is incorporated, which local business tax applies, and the image it projects to banks and partners. Yet this choice is often made lightly at the time of creation, even though it shapes the company for years afterward. More than 1.05 million businesses were created in France in 2024 according to Insee, a large share of them without dedicated commercial premises, which makes the registered office decision unavoidable for most SCI managers.

This guide details the three legal options for registering an SCI's office, their real commitment periods, their costs, and the pitfalls that can block an incorporation or turn out to be expensive at the time of a registered office transfer.

Why registering an SCI's office is a legal obligation

Under Articles L123-10 and following of the French Commercial Code, every company, including a real estate holding company, must declare a registered office address to be listed on the National Business Register. This address appears in the bylaws, on the company's official registration certificate (Kbis) and on every commercial document: invoices, quotes, contracts. Without valid proof of registration (lease, property deed, or domiciliation agreement), the incorporation file submitted through the Guichet unique is simply rejected.

The chosen address is not neutral: it also determines the municipality of reference for the local business property tax (CFE), whose rate varies from one municipality to another. A change of address during the company's life can therefore have a tax impact that needs to be anticipated.

The three options for registering an SCI's office

The manager's or a partner's home

This is the most common solution at the time of creation, for a simple reason: it is free of charge. The manager can register the SCI at their personal address, with no time limit in most cases. Two caveats apply, though: it is necessary to check that the residential lease or the co-ownership rules do not prohibit professional use of the home, and if such a clause exists, the law caps home-based domiciliation for the manager at a maximum of 5 years, giving time to find an alternative solution.

The main drawback is confidentiality: the manager's personal address becomes public, visible to anyone on a Kbis extract.

Business premises or a commercial lease

Registering the SCI in dedicated premises is rarely justified economically for a company whose only purpose is holding real estate, unless it manages a substantial rental portfolio. A standard commercial lease runs for 9 years, with the possibility of exiting every three years; for a family SCI, the term can be reduced to 3 years. This is a heavy commitment, best reserved for structures that genuinely need physical premises.

An approved domiciliation company

The third option is to entrust registration to a specialized company approved by the local prefecture. This approval, valid for 6 years, requires the domiciliation provider to have its own premises, to offer a confidential meeting space, and to report companies that have been inactive for more than three months. The domiciliation contract is regulated by law: a minimum term of 3 months, renewable by tacit agreement. This is the option that offers the best balance between controlled cost, professional image, and protection of the manager's privacy, with market rates most often ranging between €15 and €60 excluding tax per month depending on the provider and the services included (mail handling, meeting room, phone answering), according to a 2026 comparison of domiciliation offers.

Choosing an approved domiciliation company avoids the restrictive clauses of a lease or co-ownership rules, and protects the SCI against a forced change of address in the years following its creation.

What the choice of address really changes

Beyond cost, three criteria should guide the decision:

• Confidentiality: a domiciliation company protects the manager's personal address, unlike home-based registration.
• Stability: a professional domiciliation contract avoids the uncertainties of a residential lease or a co-ownership whose rules could change.
• Image: for an SCI that rents to professional tenants or deals with banks, a recognized business address makes procedures easier.

If your SCI also needs an online presence, particularly to showcase its property portfolio or its managed rental units, consistency between the official address and the company's digital image also matters: a well-built professional website, through a website creation project designed for the activity, strengthens the company's credibility with financial partners.

Transferring the registered office: the procedure and its cost in 2026

Changing an SCI's registered office address involves several mandatory steps: a joint decision by the partners approving the transfer, an amendment to the bylaws, publication of a legal notice, and then filing the amendment through the Guichet unique to update the National Business Register. In 2026, the legal notice for a civil company's registered office transfer follows a flat rate set by ministerial order of November 19, 2025: €199 excluding tax in mainland France, and €229 excluding tax in Réunion and Mayotte. Registry fees related to the incorporation file amendment come on top of this amount.

It is therefore better to plan ahead: choosing the right address from the outset avoids a costly and time-consuming transfer a few months later, as illustrated by the Marseille-based SCI whose initial choice is detailed in our article on business domiciliation in Marseille.

The mistakes that block a filing or expose an SCI

The main mistake remains fictitious domiciliation: declaring an address at which the company has, in reality, no activity or presence. The Commercial Code severely sanctions this practice, as well as operating a domiciliation business without prefectural approval: up to 6 months' imprisonment and a €7,500 fine (Article L123-11-8 of the Commercial Code). Beyond the criminal risk, a fictitious address exposes the company to a rejected incorporation, automatic deregistration, and the loss of any public aid it might otherwise claim.

Another point often overlooked: the SCI must provide proper proof of domiciliation at the time of incorporation, whether a lease, a property deed, or a signed domiciliation contract. An incomplete or poorly drafted document is one of the leading causes of filing rejection on the Guichet unique.

Our method for deciding in 3 questions

Before making a decision, it helps to answer these three questions in order:

1. Is the manager willing to make their personal address public? If not, home-based domiciliation should be ruled out immediately.
2. Does the home lease or co-ownership rules allow professional use with no time limit? If the answer is unclear, it is safer to secure the situation with an approved company rather than risk a forced transfer in 5 years.
3. Is the SCI likely to evolve (additional partners, a larger property portfolio, a more professional rental management activity)? If so, a stable professional address from the start avoids a costly change of status later on.

In most cases, for an SCI starting out with a limited property portfolio but wanting to protect its manager's privacy, an approved domiciliation company remains the most balanced choice. For structures that prefer to fully outsource these steps, dedicated support for business domiciliation helps secure the address decision from the moment the file is put together. Our team can be contacted directly to review an SCI's specific situation and project.

This administrative structuring work often ties into a broader reflection on launching the activity: our guide to launching a business in Marseille covers the other formalities not to overlook at creation, and our article on building a website for a sole trader details how to set up a consistent online presence in the first few months.

Finally, SCI managers working with an accountant should check that their firm masters the specific tax rules of a real estate holding company: our article on digital accounting expertise explains how these firms are modernizing their support for this type of structure.

Frequently Asked Questions

Can an SCI be registered at home if the manager is a tenant?

Yes, provided the residential lease does not explicitly prohibit professional use of the home. If such a clause exists, domiciliation is still possible but limited to a maximum of 5 years, giving the SCI time to find an alternative address.

What is the difference between domiciliation and a commercial lease for an SCI?

Domiciliation through an approved company relies on a flexible contract, with a minimum commitment of 3 months, renewable, while a standard commercial lease commits the company for 9 years. Domiciliation is therefore the solution best suited to an SCI that does not need physical premises to carry out its activity.

Must a change of an SCI's registered office address be officially declared?

Yes, any change of address must be the subject of a partners' decision, the publication of a legal notice, and an update of the file through the Guichet unique. In 2026, the legal notice for a civil company costs €199 excluding tax in mainland France.

What are the risks for an SCI registered at a fictitious address?

The Commercial Code provides for severe penalties: up to 6 months' imprisonment and a €7,500 fine for irregular domiciliation, on top of the risk of a rejected incorporation or automatic deregistration of the company.

Must a domiciliation company always be approved?

Yes. Only companies holding a prefectural approval, valid for 6 years, are authorized to register businesses. This approval guarantees that the provider has real premises and complies with traceability obligations, particularly regarding anti-money laundering rules.
