ERP Fire Safety Verification in France: How It Actually Works (2026)

Fire safety verification for an ERP — an établissement recevant du public — runs on two distinct gates. The first is a plan-stage review of the design documents against the règlement de sécurité contre les risques d'incendie et de panique, the regulatory framework approved by the arrêté of 25 June 1980 and amended dozens of times since. The second is an on-site reception visit before the building is opened to the public. Both gates are administered by the commission consultative départementale de sécurité et d'accessibilité (CCDSA) or its competent sub-commission, and both feed into the maire's decision to authorise opening. Get the plan-stage review wrong, and the project carries unresolved non-conformities into construction, where they cost months to fix instead of hours.

This piece walks through how the verification actually works: the ERP classification logic, the documents that get reviewed, what the commission examines at the plan stage versus on site, and where the most common errors hide. It is written for the people who carry the financial risk of getting it wrong — owners, developers, operators, and the technical directors who advise them — not for the bureaux de contrôle who already know it.

What an ERP is, and why the classification matters

An ERP is any building, premises, or enclosure where outside members of the public are admitted, whether or not they pay to enter. The regulatory framework lives in the Code de la construction et de l'habitation (CCH), articles R143-1 and following — the chapter renumbered from the former R123 series by the décret of 30 June 2021. The technical rules sit in the arrêté of 25 June 1980 and its many amending arrêtés.

Every ERP carries two simultaneous classifications. The type identifies the activity (a single letter or short code). The category identifies the maximum admissible occupancy, calculated according to rules specific to each type. The two classifications together determine which articles of the règlement de sécurité apply, what documents the project owes, and which administrative procedure governs authorisation.

The types — defined in article GN 1 of the arrêté of 25 June 1980 — split into fourteen établissements installés dans un bâtiment and eight établissements spéciaux:

The categories are defined by CCH article R143-19 and turn on the total admissible occupancy — public plus, for categories 1 through 4, the personnel who do not benefit from independent évacuation routes:

The split between the premier groupe (categories 1 to 4) and the deuxième groupe (category 5) is where the procedure diverges sharply. Categories 1 to 4 are subject to the full règlement de sécurité, the full commission consultation, the full reception visit, and the full periodic visit regime. Category 5 sits under a lighter regime, defined in the Livre III of the arrêté of 25 June 1980, and was further alleviated by décret 2025-1100, which removed the a priori control for category 5 establishments without locaux à sommeil. The technical obligations remain; only the administrative procedure simplifies.

The types of risk the regulation captures

The règlement de sécurité is built around a coherent risk model, even if its scale and amendments obscure it. The model has three pillars.

First, the structure must resist fire long enough to allow evacuation and intervention. The behaviour of the structure under fire is graded — stable au feu (SF), pare-flammes (PF), coupe-feu (CF) — and the duration required for each grade depends on the category. A category 1 ERP carries different structural fire-resistance requirements than a category 4 in the same type.

Second, the building must allow the occupants to evacuate without being trapped by smoke or flame. This is the largest body of the regulation by volume — dégagements, sorties, escaliers, désenfumage, distances to be travelled, widths to be respected, number of paths to be available — and it is also where verification catches the largest share of non-conformities. The number and width of dégagements scale with the admissible occupancy; smoke extraction (désenfumage) is required in defined volumes; evacuation distances are capped.

Third, the building must support the intervention of the secours — the Service Départemental d'Incendie et de Secours (SDIS). This includes accès des secours (a voie engin within a defined distance of the entrance, manoeuvring space, baies accessibles), the moyens d'extinction available inside the building (extincteurs, RIA, sprinkler when required, colonnes sèches in IGH-adjacent cases), and the systèmes de sécurité incendie (SSI) that detect and signal incidents.

Each pillar applies differently across the types. A type J — a structure housing elderly or disabled persons — is constrained on evacuation in a way a type W office is not, because the occupants cannot self-evacuate at the same speed. A type O hotel with locaux à sommeil carries night-evacuation constraints absent from a type M retail floor. A type U healthcare facility carries operational continuity constraints (a hospital cannot evacuate every patient instantly) that produce specific compartmentation requirements. The règlement de sécurité contains a Livre II with général dispositions for categories 1 to 4, followed by chapters specific to each type — and the type-specific chapter is where the operational reality of the asset is reflected.

What gets verified on the plan, and what on site

The plan-stage verification answers a different question from the on-site verification. The plan-stage question is: do the design documents demonstrate that the building, once built as drawn, will satisfy the règlement de sécurité? The on-site question is: has the building been built as drawn, and do its installations function as the design declared they would?

The documents required at the plan stage are detailed in the Cerfa form applicable to the project (Cerfa 13824 for an autorisation de travaux, Cerfa 14570 or its PC39 annex for a permis de construire). At minimum, the dossier includes:

• A notice descriptive covering the materials used in the gros œuvre and the interior fittings, with their fire-reaction and fire-resistance classifications
• A notice de sécurité setting out, point by point, how the project complies with the applicable articles of the règlement de sécurité — implantation, dégagements, désenfumage, moyens de secours, SSI, accessibility for the secours
• Plans — masse, niveaux, coupes, façades, toiture — with the widths of every dégagement, escalier, and sortie annotated, with the évacuation routes for each level shown, with the access conditions for the secours drawn
• Specific calculations where the design relies on them — effectif, désenfumage, défense extérieure contre l'incendie

The commission examines these documents against the règlement and produces an avis. The avis is consultatif in principle, but binding in two cases: a permis de construire cannot be issued where the commission has given an avis défavorable, and a dérogation to the règlement de sécurité cannot be granted without an avis favorable. The commission has two months to render its opinion; absent a response, the avis is réputé favorable. The plan-stage review is therefore the gate at which non-conformities are catchable at low cost — a corrected dimension on a plan costs nothing to redraw; the same corridor built 12 centimetres too narrow costs months and structural work.

Common errors caught at the plan stage in our experience verifying retail, hospitality, and mixed-use projects: dégagement widths under the minimum unité de passage requirement for the admissible occupancy; insufficient number of sorties for the calculated effectif; évacuation distances exceeding the cap for the type and category; absent or undersized désenfumage for the volumes that require it; voie engin access not respecting the maximum distance to the entrance; defective fire-reaction classification of materials specified in the notice descriptive.

The on-site verification — the visite de réception — comes after construction and before the maire authorises ouverture au public. The commission visits the completed building and checks that what was approved on plan has been built as approved, and that the equipment specified in the notice de sécurité is installed and functional. The on-site check covers items that cannot be verified on the plan: the actual functioning of the SSI, the presence and operability of fire extinguishers and RIA, the legibility of evacuation signage and the operability of safety lighting, the actual fire-reaction classification of the materials installed (which sometimes diverges from what was specified), the condition of compartmentation between zones. Where the visit identifies non-conformities, the commission gives an avis défavorable and the ouverture is blocked until they are resolved.

The administrative timeline

The instruction timeline is itself a verification constraint. For an autorisation de travaux on an ERP (no permis de construire required), the maximum statutory delay is four months from the date the file is recorded as complete. Where the project requires a permis de construire — that is, the PC39 annex is part of the dossier — the delay extends to five months. The mairie has one month from deposit to request missing pieces; while pieces are awaited, the instruction clock is suspended.

Inside that envelope, the commission has two months from receipt of the dossier to issue its avis. A practical implication: the time available to redraft a non-conformity caught by the commission is measured in days to weeks, not months. Projects that arrive at the commission with multiple substantive non-conformities either accept significant timeline slippage or absorb conditional avis favorables loaded with prescriptions to be verified on site — and prescriptions left unresolved on the day of the visite de réception block ouverture.

Where full-coverage plan verification changes the picture

The traditional verification model in France relies on the bureau de contrôle conducting a sampling-based review of the dossier. Sampling works for the largest items — the framework of the structural fire resistance, the principal dégagements, the headline desenfumage requirements. It struggles for the items that produce most of the non-conformities found at the commission stage: a dégagement that meets the minimum on the ground floor but drops below it on the second; a sortie correctly sized on the plan but feeding into a circulation that no longer meets the cumulative width requirement; a notice de sécurité that cites the right articles but specifies a material whose classement de réaction au feu does not match the application; a type-specific chapter requirement (type J night-evacuation, type O sleeping-room separation, type U compartmentation) that the general chapters do not cover.

Our team works with developers, operators, and bureaux de contrôle on full-coverage plan verification: every plan in the dossier is read, every applicable article of the règlement is checked against it, every non-conformity is located on the plan, ranked by impact, and accompanied by a remediation step. The structured report comes back in 48 hours. For an ERP project, the value is concentrated at the plan stage — the cost asymmetry between catching a non-conformity in the dossier and catching it after the visite de réception is genuinely large.

"In construction, every mistake in the plans costs months. Freeda eliminates them from day one."

ERP fire safety verification is one of the densest regulatory domains in French construction. The regulation is layered, the type-specific dispositions are detailed, and the commission's two-month window leaves limited room for iteration. Whether the verification is conducted in-house, by a bureau de contrôle, or by a service like Freeda, the operative point is that it has to happen on the plans, before the dossier reaches the commission — not after.
