FAQ

Why does Loire-Authion appear in Cartofriches?
Cartofriches lists commercial brownfields identified by local authorities, EPF and Cerema. Presence does not mean current vacancy — verify status with the town hall or directly with the owner (public cadaster).
Difference between building permit and commercial planning permission?
Sit@del lists building permits (>=800 m²). Openings <1 000 m² require no separate commercial permission (CDAC). AEC (>1 000 m²) are not reflected here.
Why does DVF price differ from commercial rent?
DVF = sale price per m² (acquiring walls). Commercial rent = annual rent per m² (landlord income). Price-to-rent ratio varies 12-20× by zone.
