What administrative steps for a swimming pool?

You have your land, your budget, perhaps even the model in mind. And then, someone asks you: "Did you think about the PLU? About the prior declaration? About the development tax?In a few seconds, a project of pleasure takes on the appearance of an obstacle course.

It must be said that between the urban planning permit to be submitted before the start of the construction site, the tax filing to be carried out within 90 days of the work, and the mandatory safety standards, the steps quickly add up... especially when you discover them as you go.

This article guides you step by step through all the administrative procedures to anticipate so that you can address your swimming pool construction project with clarity and serenity.

In-ground, semi-in-ground, or above-ground swimming pool: what administrative formalities?

In terms of regulation, it is the type of pool which conditions everything. An inflatable above-ground pool set up for a few weeks in the summer has nothing to do, administratively speaking, with a in-ground pool installed in your garden.

The distinction between fixed or mobile, temporary or permanent, and the surface area of the pool are the three criteria that determine your real obligations.

Here is a summary to help you see more clearly:

Pool type	Surface	Installation duration	Prior declaration	Building permits	Imposition
Temporary above-ground	< 10 m²	< 3 months/year	No	No	No
Temporary above-ground	10 – 100 m²	< 3 months/year	No	No	Yes (if permanent)
Buried / Semi-buried	10 – 100 m²	Perm	Yes	No	Yes
Buried or with shelter > 1.80 m	100 m²	Perm	No	Yes	Yes

Thus, a 8x4 m polyester shell swimming pool (32 m²), permanently buried in your garden, is subject to prior declaration of work. This is the case for the vast majority of In-ground pool projects for individuals. An above-ground pool installed for less than three months a year is exempt from planning formalities, but may still be subject to taxation depending on its actual duration of use.

Prior declaration of works for a swimming pool: how to fill out the CERFA form?

For the majority of projects inground pools between 10 and 100 m², the formality to be completed at your town hall is the prior declaration of work. It's a lighter procedure than the building permit, but it remains mandatory and must absolutely be submitted before the start of the construction site.

Which CERFA form for a swimming pool prior declaration?

The Prior declaration of works for a swimming pool is carried out via the CERFA form no. 13703*06, available free of charge on the service-public.fr website or directly from your town hall. This document allows the municipal administration to verify that your swimming pool construction project respect the rules of the Local Urban Plan (PLU) in force in your municipality: minimum distances from boundary lines, exterior appearance rules, and buildable areas allowed on your plot.

Before filling out the form, it is advisable to consult your municipality's PLU (directly at the town hall or on the urban planning geoportals) in order to identify any specific constraints on your land in advance.

What documents should be attached to the prior declaration file for a swimming pool?

A complete prior declaration file for a swimming pool generally includes the following documents:

• An location plan of land in the municipality,
• An dimensioned master plan indicating the precise location of the basin in relation to property boundaries and existing constructions,
• High-performance photographs of the immediate and distant environment allowing an appreciation of the project's landscape integration,
• Local descriptive notice if the architectural or regulatory context requires it.

Some town halls may request additional documents, particularly when the land is located in an area subject to specific architectural rules.

An incomplete file leads to a request for missing documents, which automatically suspends the processing period and consequently postpones the start of the work.

What is the processing time for a prior declaration of works?

The the legal investigation period is one month starting from the filing of the complete application. This period is extended to two months if your land is located within the perimeter of a historical monument or in a heritage protection zone.

The silence of the town hall after this period constitutes tacit agreement. In practice, it is strongly recommended to request a non-opposition certificate to legally secure your project.

At Aboral Piscines goes, the creation and monitoring of this file are part of the support offered to each client from the project study phase.

When is a building permit required for a swimming pool?

If your prior declaration of work covers the vast majority of private pool projects, some situations require going further. The building permit is then mandatory, with a more complete file to be drawn up and processing times that can reach three months.

What are the thresholds that trigger the obligation for a building permit?

Three situations make a building permit mandatory for a swimming pool:

• The surface any in-ground swimming pool exceeding 100 m² in area requires a building permit, without exception.
• Pool shelters : if the height of the shelter exceeds 1.80 m, a permit is required even for a standard-sized pool. This is a point that many owners overlook when choosing their equipment.
• The land location : if your property is located within the perimeter of a historic monument, in a listed or registered site, or in a protected natural area, a building permit may be required regardless of the pool's surface area. In these cases, the heritage or environmental sensitivity of the area takes precedence over size criteria.

CERFA form and processing times for a swimming pool building permit

The permit application is made via the CERFA form no. 13406*06. The file is more complete than a simple prior declaration: it notably includes an architectural notice, graphic documents for landscape integration, and, depending on the case, an opinion from the Architect of French Buildings.

The statutory processing period is a minimum of two months, which can extend to three months in protected areas.

Swimming pool in a protected area: the special cases that can block your project

In France, many territories are subject to urban planning regulations applicable specific ones that apply even to seemingly minor projects. Before submitting any file, it is therefore essential to check the regulatory status of your land.

All terrain located within a 500-meter radius of a historic monument : is automatically submitted for the opinion of the Architect of French Buildings (ABF). This opinion is consultative or compliant depending on the areas, and can extend processing times by several weeks.

The listed and registered sites, they are instructed by the DREAL and may in certain cases be subject to refusal.

Finally, mandatory risk zones (flood, landslide) require consultation of the Risk Prevention Plan (PPR) before any deposit.

For all these situations, the advice of an experienced pool professional is invaluable: it allows for anticipating constraints and adapting the project even before submitting the file, thus avoiding costly back-and-forth in terms of time and money.

Declaring your swimming pool to the tax authorities: the 90 days not to miss

Once the work is completed, the administrative formalities do not stop for that reason. A major tax obligation falls on any owner who has had an in-ground swimming pool built: to declare it to the tax authorities within 90 days of the completion of constructionThis deadline is imperative: failure to meet it will result in financial penalties and, in some cases, the permanent loss of a property tax exemption.

How to declare your swimming pool to the tax authorities?

The swimming pool declaration to the tax authorities is carried out via the form 6704-IL (IL model), available from your public finance center, or directly online from your personal space on impots.gouv.fr , section "Real Estate".

This statement allows the administration to re-evaluate the assessed rental value of your property, base of calculation of your property tax annual.

What concrete tax impact for an in-ground swimming pool?

The installation of an in-ground swimming pool generates two distinct types of taxation:

• The development tax is a single tax, due once at the time of construction. For a 8×4 fiberglass pool (32 m²), its amount generally varies between €80 and €650 according to the current municipal and departmental rates;
• The property tax, she, is annual. In some municipalities, a temporary exemption for two years may be granted but only if the tax declaration is made within 90 days of the completion of the works. After this period, this exemption is permanently lost.

Declaration	Form / Channel	Deadline	Risk in case of forgetting
Declaration of work	CERFA 13703*06 / Town Hall	Before the start of the construction site	Illegal work, restoration
Declaration of Completion (DAACT)	CERFA 13408*05 / Town Hall	Upon completion of the work	Nullity of the authorization
Tax declaration	Form 6704-IL / impots.gouv.fr	90 days after completion	Penalties, loss of exemption

Mandatory safety standards: devices to consider from the design stage

The regulations does not limit itself to urban planning and taxation. In France, the law of January 3, 2003 requires that any in-ground private swimming pool be equipped with at least one standardized safety device, in order to prevent the risks of drowning, particularly among young children.

This obligation concerns all of the in-ground and semi-inground pools, regardless of their surface area. The absence of a compliant device exposes to a fine of up to €45,000.

Four types of devices are recognized by the regulations, each responding to a AFNOR standard specific. The choice must be made from the project's inception, as some (like the submerged roller shutter under the deck) integrate directly into the basin structure.

Device	Standard	Benefits	Indicative cost
Safety barrier	NF P 90-306	Very reliable, permanent	€1,500 – €4,000
Immersion alarm	NF P 90-307	Discreet, inexpensive	200 – 600 €
Security cover	NF P 90-308	Double use safety + insulation	2,000 – 8,000 €
Pool shelter	NF P 90-309	Versatile, all-season protection	5,000 – 20,000 €

The automatic shuttersproposed by Aboral Shop (notably the Deck range by Kristal Pool, in accordance with the nNF P 90-308 standard) simultaneously meet the obligation of safety, thermal insulation of the pool, and the overall aesthetics.

This is a solution particularly appreciated by owners who wish to avoid the visual constraint of a barrier while fulfilling their legal obligation.
