French rent control is not one rule — it is two overlapping systems that most landlords confuse. The first applies in all 28 zone tendue urban areas and caps how much rent can rise between tenants. The second is an experimental programme adopted by certain large cities and caps the absolute rent level against a government reference benchmark. Getting either wrong exposes you to an administrative fine of up to €15,000 and a court-ordered refund.
The two rent-control mechanisms
1. Rent increase cap (Article 18, 1989 Act) — all zone tendue areas
Applies across all 28 zone tendue urban areas. Rule: when a new tenant moves in, the rent may not exceed the previous tenant's rent, adjusted upward by at most the last published IRL index. Exceptions exist for properties vacant more than 18 months or where significant improvement works have been carried out (≥ 50% of one year's rent), within defined limits.
2. Rent level cap (Article 140, ELAN Act) — experiment cities only
An opt-in experiment by city. Cities where it is in force in 2026:
- Paris
- Lille
- Lyon
- Bordeaux
- Montpellier
- Grenoble
- Pays Basque
- Marseille (partial)
- Rennes (in progress)
The rent may not exceed the reference rent ceiling — typically the median rent for the zone × 1.2. This ceiling is set annually by prefectural order, broken down by geographic zone, lease type (furnished / unfurnished), number of rooms, and construction era.
How to calculate the rent ceiling
For cities with a rent level cap, the three-step method:
- 1. Find the geographic zone on the prefectural order map (Paris has 14 zones, Bordeaux and others have their own sectors).
- 2. Look up the reference rent ceiling for your configuration: furnished or unfurnished, number of rooms, construction era (pre-1946, 1946–1970, post-1990, etc.).
- 3. Multiply by the habitable surface(excluding annexes — cellar, parking) to get the monthly ceiling excl. charges.
Rent supplement (complément de loyer): a supplement above the ceiling is allowed only if the property has genuinely exceptional location or comfort characteristics compared with similar properties in the same zone. It must be justified in the lease and can be challenged by the tenant within 3 months of signing.
Mandatory lease mentions in controlled cities
In cities with a rent level cap, the lease must state:
- 1. The reference rent in force at the date of signing.
- 2. The reference rent ceiling (= the cap — median × 1.2).
- 3. The reference rent floor (for the tenant's information).
- 4. The amount and justification of any rent supplement.
Missing these mentions makes the lease contestable. See the full list in our compliant lease template guide.
Annual rent revision during the tenancy
The level cap applies at signing. The annual IRL revision can still apply during the tenancy if the lease includes a revision clause — but the revised rent must itself remain within the ceiling in force at the revision date. In DPE-rated F or G properties, any revision has been banned since 24 August 2022 regardless of zone.

Frequently asked questions
How do I check if my property is in a zone tendue?
Use the French government's official simulator at service-public.fr. Zone tendue properties are those in the 28 urban areas listed in Decree 2013-392 of 10 May 2013 (Paris, Lyon, Marseille, Bordeaux, Lille, Toulouse, Nice, Rennes, Strasbourg, Grenoble, Montpellier, and others).
What is the difference between the rent increase cap and the rent level cap?
The rent increase cap (Article 18, 1989 Act) applies across all zone tendue areas: it prevents landlords from raising the rent above the previous tenant's rent (adjusted for IRL) when a new tenant moves in. The rent level cap (Article 140, ELAN Act) applies only in cities that have adopted the experiment (Paris, Lille, Lyon, Bordeaux, Montpellier, Grenoble, etc.): it sets an absolute ceiling equal to the reference rent (median) multiplied by 1.2, regardless of what the previous tenant paid.
Can the tenant challenge a rent above the cap?
Yes. The tenant must first refer the matter to the departmental conciliation commission (CDC) — this step is mandatory before going to court. If conciliation fails, they can bring a claim before the civil court. A successful challenge results in a rent reduction and reimbursement of overpayments from the start of the lease.
Does the rent level cap apply to existing leases?
The level cap applies at the time the lease is signed and at each renewal. Leases signed before the experiment was introduced in a given city are not affected retroactively — but the re-letting cap (IRL constraint) applies whenever a new tenancy starts.
Do furnished lettings also come under rent control?
Yes. Both the increase cap and the level cap apply to furnished residential leases in covered areas. Furnished lettings have their own reference rents (generally higher than the unfurnished benchmarks for the same zone).
