About this app

Look beyond the facade.

Before buying or renting, everyone checks the apartment. No one checks the BUILDING. BâtiSain fills this blind spot: in 10 seconds, during your visit, find out what the national register says about the building.

Open the app, then the map of your neighborhood, tap on a building, and read the verdict. No account required, and it's free.

WHAT YOU SEE FOR EACH BUILDING
- The register's verdict: nothing to report, points of concern, or ongoing proceedings — and most importantly, WHY, explained point by point.

- The registered property manager, the current mandate, the year of construction, and the number of units.

- The building's Energy Performance Certificate (EPC) rating (A to G) and the energy efficiency alert.

- Actual prices per square meter from sales (DVF) and their evolution. - Risks at the address: clay soils, flooding, radon, soil pollution.

FACTS, NOT JUDGMENTS
BâtiSain doesn't rate or judge: it provides public, dated, and sourced data. Each technical term is explained in two sentences ("Is it serious?").

640,000 CONDOMINIUMS
All of France, based on the National Condominium Register, updated daily.

THE THIRD PERSPECTIVE ON BUYING PROPERTY
The listing sells the apartment. The diagnostic report focuses on the dwelling. BâtiSain focuses on the building—the only perspective no one else covers. Share the information sheet with your notary.
