Under Article 3 of the Loi du 6 juillet 1989 (as amended by Loi ALUR), every bail must include:
• Identity of the parties: Full names, addresses, and contact details of landlord(s) and tenant(s)
• Property description: Address, type (apartment/house), number of rooms, living area (surface habitable in m², measured per Loi Boutin), floor level, and annexes (parking, cellar)
• Designated use: Habitation (residential) only, or mixte (residential + professional)
• Rent amount: Base rent (loyer), charges (provision pour charges), and payment terms (monthly, quarterly)
• Deposit amount: Maximum 1 month's rent excluding charges for unfurnished; 2 months for furnished. No deposit for bail mobilité.
• Duration and start date: Lease term and effective date of occupancy
• Means of payment: Bank transfer, cheque, or other accepted methods
• Encadrement des loyers: If the property is in a rent control zone (Paris, Lyon, Lille, Montpellier, Bordeaux, etc.), the lease must state the reference rent (loyer de référence), the increased reference rent (loyer de référence majoré), and any complément de loyer
Missing any mandatory clause makes the lease voidable — a court can nullify it if challenged. AdminLanding's bail generator builds every required clause in order, with the Loi 1989 references attached, so the lease is compliant at signature rather than retroactively patched.
