RegistreDesPermis.fr is a French online platform that brings together public information on planning and building authorizations, helping users monitor development activity across the country. Its searchable register covers building permits, prior declarations, development permits and demolition permits, with more than three million authorizations indexed. Users can explore records by reference, authorization type, company, city or territory, and consult dedicated pages for regions, departments and municipalities. Permit records present practical details such as project characteristics, location, status and available source information.

The platform serves both construction businesses and property developers through professional tools tailored to their needs. Construction firms can identify potential projects by trade and service area, assess their commercial relevance, and organize contacts, follow-ups and team-shared opportunities. Developers can filter permits by criteria such as project size and housing numbers, identify cases for potential acquisition, and share selections with colleagues. Users can also create alerts to track new authorizations by city, department or region. RegistreDesPermis.fr supports free searches, with professional subscriptions offered for additional prospecting and monitoring features.
