You need to go to Annonces > select your listing > Règlementation > select with type of housing is your listing between "Résidence principale" (subject to 120 day per year limit), "Résidence secondaire" (subject to registration in yur town office) or "Hébergement non résidentie" (subject to specific rules and regulation).
If necessary go to Législation Locale in order to fill your registration number (given by your town office).
