The information exists, but it is scattered
To underwrite a building or a specialty risk, underwriters have to cross-check sources that do not talk to each other.
- Dangerous building and safety orders are published town by town, often as PDFs
- Natural catastrophe decrees, hazards and land registry data sit in separate databases
- A building under an order can be underwritten, or stay in the portfolio, without anyone knowing
Dangerous building and safety orders, and police measures
This is the hardest data to get, and the most decisive. We have done the work of covering the whole of France: Sonar collects the orders published by French towns, reads them, structures them and links them to the address concerned. Thanks to that coverage, the data is easy to refresh.
- Dangerous building (péril), safety and unfit housing orders
- Police measures: occupancy bans, evacuations, required works
- Up-to-date status: order in force or lifted
- Dangerous building orders, safety orders and police measures refreshed easily, across all of France
- The source PDF of every order, one click away in the tool
One address, all the data that matters
Natural catastrophe decrees
The town's history of CatNat recognitions: floods, droughts, ground movements.
Natural and technological hazards

Land registry and plot
Plot, surface area and building footprint to check what was declared.
Building characteristics
Year of construction, height, use and visible features of the building.
Property transactions
Recent sales around the address to gauge the property's value.
