A declared candidate since 3 May 2026, Jean-Luc Mélenchon presented his housing plan at the end of September. Construction, bringing vacant homes back into use, regulating tourist lets, wealth taxation: several measures directly concern landlords. Here is what the programme provides, what it would change in Paris, and what remains to be specified.
A plan focused on public supply and the existing housing stock
La France insoumise's “BTP et logement” (construction and housing) plan starts from one observation: almost 10% of the housing stock is said to be vacant, more than 3 million homes according to the programme. It provides for €12 billion of additional public investment a year and is built around four pillars: building, bringing existing homes back into use, renovating, and regulating lettings.
The main measures
Building and mobilising the existing housing stock
- 400,000 affordable homes a year for five years, including 200,000 public homes.
- Around 150,000 homes a year from the existing housing stock, through the requisition of vacant homes, subsidised rent agreements, changes of use and limits on tourist lets.
- A single tax on vacant homes, progressive according to the number of vacant homes owned.
- Converting unused offices and premises: 50,000 homes a year, twice as many as today.
Regulating lettings
- A mandatory letting permit for every letting, throughout France.
- Furnished tourist lets limited to 60 days a year, subject to quotas in high-pressure areas, banned in the very centre of major cities, and stripped of their tax advantage.
- An effective ban on letting energy-inefficient homes.
- Rent control extended to the whole country, with tighter checks and a new housing inspectorate, according to a statement by the LFI parliamentary group on 3 September 2026.
Renovating
- 700,000 homes insulated a year, with 100% of the works covered for low-income households, tapering with income.
- Owners of more than 5 homes would be excluded from this support.
Tax and inheritance
- A progressive property tax, based on each person's actual total wealth.
- A cap of 5 homes that can be passed on by inheritance: beyond that, the properties would be requisitioned by the State.
- The return of a wealth tax, set out in the tax section of the programme.
The programme justifies these measures by the concentration of rental housing: according to it, 3.5% of households own more than five homes and hold half of all rented homes.
What it would change for a Paris property owner
| Your situation | What the programme provides |
|---|---|
| Standard unfurnished or furnished letting | Rent control already applies in Paris; a letting permit and tighter checks would be added |
| Mobility lease | Already rent-controlled in Paris; would also require a letting permit |
| Civil lease, medium-term | No specific measure in the published plan; the letting permit would apply to every letting |
| Furnished tourist let | 60 days a year instead of 90 nights for a main residence in Paris, quotas, a ban in the very centre, end of the tax advantage |
| Vacant home | Progressive tax according to the number of empty homes owned, possible requisition |
| More than 5 homes | Progressive property tax, exclusion from renovation support, inheritance cap |
What remains uncertain
- A programme is not a law: each measure would require a majority in the National Assembly and specific legislation.
- Constitutional questions: requisitions and the cap on inheritable property would have to be reconciled with the right to property, protected by the Constitution, under the review of the Constitutional Council.
- Details still to be specified: the vacancy tax scale, the definition of the very centre, how the letting permit would work, funding.
Supporters see these measures as a response to the affordable housing crisis and to the concentration of housing ownership; critics, notably among owners' representatives, fear a decline in private rental investment and a shrinking supply.
How to prepare, without speculating
- Do not make property decisions based on a programme: six months before the vote, nothing is settled.
- Bring your property into compliance now: energy rating, occupancy declaration, registration if it is let short-term. It is useful whatever the outcome.
- Favour flexible arrangements: a civil lease of a few months leaves you room to adapt.
