The title of architect is protected by the law of January 3, 1977, on architecture. Practicing under this title without registration on the Order’s roll constitutes a criminal offense. The boundary between authorized missions and illegal practice is based on specific criteria determined jointly by diploma, status, and type of project.
Registered architect, project manager, interior architect: what the law allows
The confusion between these three statuses fuels the majority of disciplinary disputes and criminal prosecutions. The table below summarizes the structural differences.
| Criterion | Registered architect | Non-architect project manager | Interior architect |
|---|---|---|---|
| Protected title | Yes (law of January 3, 1977) | No | No |
| Registration on the roll | Mandatory | Not required | Not required |
| Building permit signature | Yes | No | No |
| Specific professional insurance (MAF) | Mandatory | Not mandatory (classic ten-year insurance) | Variable depending on missions |
| Disciplinary control by the Order | Yes | No | No |
| Design and site supervision | Yes | Yes, within the legal threshold | Limited to interior design |
A project manager can design projects and supervise sites, but he cannot hold the title of architect or sign a building permit. The interior architect, for his part, intervenes in the arrangement of spaces without affecting the load-bearing structure of the building.
The philippon architect website details the concrete implications of this distinction for professionals not registered on the roll.
Threshold for mandatory recourse to a registered architect
The law on architecture requires the recourse to a registered architect for any building permit application beyond a certain surface threshold. Below this threshold, an individual can submit their application themselves or entrust the design to a non-registered project manager.
This threshold constitutes the pivot of the legal framework. Below it, project management remains open to non-registered professionals. Above it, only a registered architect can establish the architectural project attached to the building permit application.
Territorial officials benefit from a specific exemption. A public agent holding an architect diploma can develop architectural projects on behalf of their local authority without being registered on the roll, provided they do not practice liberally in parallel.
Criminal sanctions for illegal practice or usurpation of the title of architect
Illegal practice of the architect profession and usurpation of the title are two distinct offenses provided for by the penal code and the 1977 law. The disciplinary chamber of the Order deals with ethical breaches, while criminal courts judge criminal offenses.
- Usurpation of the title of architect: using the term “architect” on commercial documents, quotes, business cards, or websites without being registered on the roll exposes one to criminal prosecution.
- Illegal practice of the profession: performing missions falling under the architect’s monopoly (signature of building permits, architectural project beyond the threshold) without registration constitutes an offense.
- The client’s liability may also be engaged when they knowingly entrust a regulated mission to an unauthorized person, which can lead to the cancellation of the building permit.
The Order of Architects has direct referral power and actively monitors online advertisements and matchmaking platforms. Several recent disciplinary decisions concern professionals who presented themselves as architects on digital platforms without being registered on the roll.
Non-EU nationals: project-by-project authorization
An architect qualified outside the EU and EEA cannot register directly on the Order’s roll. The Ministry of Culture issues a specific authorization for the realization of a determined architectural project, without permanent registration.
This procedure is strictly regulated. The authorization is limited to a single project, defined in advance. The applicant must justify their qualifications, professional experience, and take out insurance covering their ten-year liability for the project concerned.
In contrast, nationals of the EU and EEA benefit from a regime of free provision of services. They can practice in France temporarily and occasionally after a simple prior declaration to the regional council of the Order, without registration on the roll. This declarative regime does not exempt them from mandatory professional insurance.
Liberal collaborator and accumulation of statuses: the limits of practice without proper registration
Liberal collaboration allows an architect to work with a registered colleague, without a subordinate relationship, while developing their own clientele. The liberal collaborator must themselves be registered on the roll and have their own professional insurance.
This status does not provide a way to circumvent the registration obligation. Any architect practicing in their own name, even under a collaboration contract, must be registered on the roll. The absence of registration exposes the collaborator to the same criminal sanctions as any other non-registered professional.
The accumulation of statuses (partner in an architecture firm and liberal in parallel) is permitted, but each mode of practice requires valid registration and distinct insurance coverage.
The distinction between protected title and design missions accessible to non-registered professionals remains the main point of friction. A competent professional in building design can legally practice under the status of project manager, provided they never claim the title of architect and respect the regulatory thresholds imposing recourse to a registered architect.
