Renting in France: get notice periods and deposit rules right in your AI assistant

Notice period, security deposit, furnished or unfurnished lease: ask Claude or ChatGPT about renting in France and get the rule for your type of lease from the official Service-Public.fr sheets.

Add French Administrative Procedures to your AI assistant

Most rental questions in France have a precise answer: one month or three months of notice, one or two months of rent as a deposit, or no deposit at all. The catch is that the answer depends on the type of lease, and a general AI model often gives the rule for the wrong one. The French Administrative Procedures brain lets Claude and ChatGPT read the official Service-Public.fr sheets, with each rule tied to its situation.

Same question, different answers

What the official sheets say, by type of lease (Service-Public.fr, checked November 2026)
RuleUnfurnished (logement vide)Furnished (logement meublé)Bail mobilité
Maximum deposit1 month of rent, excluding charges2 months of rent, excluding chargesNot allowed
Minimum lease length3 years, except special cases1 year (9 months for a student)1 to 10 months
Tenant's noticeDepends on the case (the sheet lists reduced notice situations)1 month, even on a 9 month student lease1 month

This table is an example of what the brain returns, not a substitute for it. Rules and amounts change: your assistant reads the current sheet each time and gives you its date.

Questions to try

  • "I rent a furnished flat in Paris: how much notice do I give, and when do I get my deposit back?"
  • "Quel est le montant maximum du dépôt de garantie pour un logement vide ?"
  • "My landlord wants three months of deposit for an unfurnished flat. Is that allowed?"
  • "Can I pay my last month's rent with the deposit?" (the sheet says no)
  • "Which repairs are the landlord's responsibility?"

Why the assistant asks about your lease first

Each passage the brain returns carries its situation, such as "Logement meublé" or "Logement vide". The answering note tells the assistant to use only the passages for your situation, and to ask when it does not know which one applies. That is the difference between a confident wrong answer and a short question followed by the right one.

The brain indexes the full "vosdroits" export of Service-Public.fr, published by DILA (Direction de l'information légale et administrative) under the Licence Ouverte 2.0: about 3,000 official sheets for individuals, split into some 49,000 passages that keep their situation and heading. KBrain refreshes it every week. Answers are general information from the official sheets, not legal advice.

Questions people ask.

How much notice does a tenant give in France?

It depends on the lease. For a furnished flat the official sheet gives 1 month. For an unfurnished flat the general rule is longer, with reduced notice in listed situations. Ask your assistant with the brain connected and it gives the rule for your case with the sheet's link.

What is the maximum security deposit in France?

According to the Service-Public.fr sheets: 1 month of rent excluding charges for an unfurnished flat, 2 months for a furnished flat, and none for a bail mobilité. Check the current sheet, which the brain returns with its date.

Does the brain know my city's rent control?

It knows what the national sheets say, including where rent control applies in general. It does not hold local rent tables or your landlord's file.
