A communal land is not requested like one buys a plot on the private market. The municipality remains the owner of a land heritage subject to public or private domain rules, and the transfer procedure follows steps that most guides overlook. Here we detail the technical points that determine the success of a request.
Public domain or private domain of the municipality: the prerequisite that conditions everything
Every municipal plot falls under either the public domain (allocated to public service or public use) or the private domain of the community. This distinction determines the feasibility of the request itself.

A plot classified in the public domain is subject to the principle of non-alienability. The municipality cannot sell it until it has been decommissioned and then reclassified by a resolution of the municipal council. Decommissioning implies that the land is no longer used for public purposes, and reclassification shifts it to the private domain.
A plot already listed in the municipal private domain can be transferred without this double step. Before drafting any letter, we recommend checking this status with the town hall’s urban planning department or by consulting the property record in the land registry.

To understand how to request a communal land from the town hall, one must first know which legal regime the plot is subject to; otherwise, the file will be rejected as soon as it is processed.

Verification of PLU zoning and risks before any request
Submitting a purchase request without first verifying the zoning of the Local Urban Plan is like building a file on sand. The PLU sets the authorized destination for each plot: urban zone (U), to be urbanized (AU), agricultural (A), or natural (N).
A communal plot classified in zone A or N will not be transferable for a construction project, unless the urban planning document is modified. This verification is done at the town hall, at the urban planning department, or online when the municipality has digitized its documents.
Also filter servitudes and risks
Competitors rarely mention the necessity of cross-referencing zoning with information on risks. The ERRIAL tool (State of Regulated Risks for the Information of Buyers and Tenants) allows consultation of natural, mining, technological risks, and the radon potential of a plot. A plot exposed to a flood risk or located within the perimeter of a prevention plan may have its buildability severely constrained.
We recommend attaching a summary note to the request file proving that these verifications have been made. This enhances the project’s credibility with elected officials.
Content of the communal land request file
The request takes the form of a letter addressed to the mayor, but a simple template letter is not enough to trigger a favorable response. The file must demonstrate the coherence of the project with the municipality’s objectives.
Here are the elements to include:
- The precise identification of the targeted plot (cadastral references, section, number, approximate area) and the mention of its domain status if you have obtained it.
- A detailed description of the proposed project (housing construction, artisanal activity, property extension) with an argument on its compatibility with the current PLU.
- Proof that the land is not subject to any blocking servitude, accompanied if possible by an extract from the operational urban planning certificate (CUb) confirming the technical feasibility of the project.
- A financing plan or, failing that, a bank certificate of borrowing capacity, to prove the seriousness of the approach.
Municipalities prefer requests linked to a specific project rather than generic acquisition solicitations. Elected officials assess the communal interest of the transfer: creation of housing, economic dynamism, filling in gaps.
Digitization of urban planning requests
Since 2022, many municipalities have set up digital counters for urban planning procedures. Some town halls now accept requests submitted electronically, including those related to communal land. Check the municipality’s website to see if an online form or a dedicated email address exists before sending a paper registered letter.

Municipal council deliberation and evaluation of the sale price
The transfer of communal land to a private individual does not fall solely under the mayor’s power. Only the municipal council can authorize the sale by deliberation, after the question has been placed on the agenda.
The evaluation of the price is a sensitive point. The municipality must seek the opinion of France Domaine (State Real Estate Directorate) to obtain an estimate of the market value of the land. This opinion is mandatory for local authorities when the transaction amount exceeds a regulatory threshold. The municipality is not obliged to sell at the estimated price, but it cannot transfer below that without justification of general interest.
Advertising the sale and competition
Some municipalities publish a notice of sale to allow other potential buyers to come forward. This advertising, although not systematically mandatory for the private domain, is increasingly practiced for the sake of transparency. Anticipating this eventuality avoids disappointments if another candidate presents a project deemed more favorable.
Strategy for modifying the PLU for non-buildable communal land
When the targeted land is classified as non-buildable, a simple purchase request will yield nothing. There are two levers to change the classification of a plot:
- The simplified modification of the PLU, a faster procedure, usable when the change does not undermine the overall economy of the urban planning document.
- The revision of the PLU, a heavy procedure (public inquiry, opinions from associated public bodies), reserved for structural changes in zoning.
These procedures fall under the initiative of the municipality. An individual cannot trigger them directly, but they can submit a motivated request to the mayor demonstrating that the reclassification of the plot serves an objective identified by the Sustainable Development and Planning Project (PADD). Some urban planning law practitioners assist project holders in compiling this type of substantiated file.
The town hall’s response will always depend on the alignment between the proposed project and local land policy. A solid file, well-documented in regulatory and urban planning terms, remains the best lever to obtain a favorable response from the municipal council.
