France Property Risk Scraper — Flood, Seismic, Radon, ICPE (Géorisques API)

Turn a list of French addresses into a full natural + industrial risk dataset. For each address this scraper geocodes to GPS + INSEE, then pulls flood zone, seismic zone (1-5), radon potential (1-3), clay shrink-swell (retrait-gonflement des argiles), nearby ICPE / Seveso sites, polluted soils (CASIAS), underground cavities, ground movements, the full GASPAR risk catalog and the CatNat disaster history. Built on the official Géorisques (BRGM / Ministère) open data. HTTP-only, $0.005 per address.

What is the France Property Risk Scraper?

The France Property Risk Scraper is an Apify actor that builds a per-address risk report from the official Géorisques API, the French government's authoritative natural- and technological-risk service run by BRGM for the Ministère de la Transition écologique. Feed it a list of free-text French addresses (or INSEE commune codes) and it returns one structured row per address with every regulated risk a buyer, notaire, insurer or lender needs for due diligence.

It is the same data behind the mandatory ERRIAL / État des Risques form attached to every French property sale or lease — now scriptable, exportable and queryable in bulk. No authentication, no API key, no rate limits to fight: the Géorisques and Base Adresse Nationale APIs are free public open data.

This scraper attaches directly to the French real-estate data family: pair it with DVF transactions, multi-source property listings and ADEME DPE diagnostics to enrich any address with price, energy and risk in one pipeline.

Which risks does it return?

For every address the scraper aggregates ten official sources:

• Flood — flood-zone flag derived from the GASPAR catalog plus the Atlas des Zones Inondables (AZI) programmes covering the commune.
• Seismic zone — the regulatory zonage sismique class from 1 (very low) to 5 (strong).
• Radon potential — commune radon class 1 to 3 (3 = significant potential).
• Clay shrink-swell (RGA) — retrait-gonflement des argiles exposure, the leading cause of crack damage to French houses.
• ICPE industrial sites — count and sample of classified installations nearby, with Seveso status.
• Polluted / former-industrial soils — count and sample of CASIAS / sites pollués within the radius.
• Underground cavities — count of recorded cavités souterraines (quarries, sinkholes).
• Ground movements — count of recorded mouvements de terrain (landslides, subsidence).
• GASPAR risk catalog — the full list of declared natural and technological risks for the commune.
• CatNat history — number of natural-disaster declarations (arrêtés de catastrophe naturelle) on record.

Use cases

• Real-estate due diligence — pre-screen a portfolio of addresses before purchase or lending; flag passoires de risque the same way DPE flags passoires thermiques.
• Notaires & ERRIAL automation — auto-generate the risk inputs of the État des Risques for every sale file.
• Insurance underwriting — score flood, clay and CatNat exposure across a book of properties for pricing.
• Marchands de biens / promoteurs — rule out ICPE, polluted-soil and cavity hazards before a deal.
• Proptech & CRM enrichment — add a risk layer to any address-keyed database, alongside price and energy data.

Input

{
  "addresses": [
    "8 boulevard du Port, 80000 Amiens",
    "1 place de la Comédie, 34000 Montpellier"
  ],
  "radius_m": 500,
  "maxResults": 50
}

You can pass insee_codes (e.g. ["80021", "75056"]) instead of addresses for commune-wide lookups. radius_m controls the search radius for nearby-site risks (ICPE, polluted soils, cavities, ground movements).

Pricing

PAY_PER_EVENT — $0.005 per address analyzed (= $5 per 1,000 addresses). Each successfully geocoded and analyzed address is one charge. Addresses that cannot be geocoded are returned as a not_found record and are not charged.

FAQ — France property risk data

Where does the data come from? The official Géorisques API (BRGM / Ministère de la Transition écologique) for risks, and the Base Adresse Nationale (api-adresse.data.gouv.fr) plus geo.api.gouv.fr for geocoding. All free public open data.

Is this the same as the ERRIAL / État des Risques? It uses the same underlying Géorisques sources that feed the regulatory État des Risques form, returned as structured data for bulk use. Always confirm the official ERRIAL for a binding legal document.

Can I run it on thousands of addresses? Yes — set maxResults and pass a long addresses list. The actor throttles politely and returns one row per address.

Do I need a proxy or API key? No. The Géorisques API has no anti-bot and no key requirement.
