Do you want to install a swimming pool in your garden? Before starting the work, it is important to know the authorizations required by French law to build a swimming pool. The rules change depending on the size and type of pool: no formalities are required for pools smaller than 10 m², a prior declaration is sufficient for those between 10 and 100 m², while a building permit becomes necessary for pools over 100 m² or with a high enclosure. In this article, we detail each administrative step to help you carry out your project legally.
What administrative steps are required to build a swimming pool?
Before diving into a pool construction project, it is essential to be aware of the permits required by law to build a swimming pool. These formalities mainly depend on the size and type of pool you wish to install. In France, three situations are possible: no formalities for small pools (less than 10 m²), a prior declaration for medium-sized pools (between 10 and 100 m²), or a building permit for large installations (over 100 m²) or those with a high enclosure. The regulations also take into account the duration of installation for temporary pools and the project's location, particularly in protected or classified areas.
What authorizations are required to build a swimming pool based on size and type?
The authorizations required to build a swimming pool vary according to several criteria. The pool area is the main factor, but the type of cover and the duration of installation also play an important role. The table below summarizes the main situations:
| Pool Type | Authorization Required |
|---|---|
| Less than 10 m² | No formalities (except in protected areas) |
| Between 10 and 100 m² (uncovered or with an enclosure less than 1.80 m high) | Prior declaration of works |
| Over 100 m² or with an enclosure over 1.80 m high | Building permit |
| Temporary above-ground pool (max 3 months) | No formalities (outside protected areas) |
Pools exempt from authorization: which ones?
Some pools are exempt from any administrative procedures. This is the case for pools with a surface area not exceeding 10 m², provided they are not located in a protected or classified area. Movable above-ground pools are also covered by this exemption if they are installed for a maximum duration of 3 months per year and outside a protected area. In a protected area, this duration is reduced to 15 days if the surface area remains below 10 m². This flexibility allows owners to easily install small pools or temporary pools for the summer season without administrative hassle.
Prior declaration for standard-sized pools
For medium-sized pools, with a surface area between 10 m² and 100 m², a prior declaration of works is mandatory. This procedure also applies to covered pools where the height of the enclosure does not exceed 1.80 m. The declaration must be submitted to the town hall before the start of the work and includes a complete file with plans, photographs, and possibly a descriptive notice. The processing time is generally one month, during which the administration examines the project's compliance with local urban planning rules. This simplified formality allows owners to complete their project more quickly than with a building permit, while still complying with the legal framework.
Building permit for large pools or those under an enclosure
Large pools or those with a significant cover require a more comprehensive authorization. A building permit is required for any pool exceeding 100 m² in surface area or for those whose fixed or movable enclosure exceeds 1.80 m in height. The file to be prepared is more detailed than for a prior declaration and includes, in particular, a Cerfa form, precise plans, and a comprehensive descriptive notice. The processing time is longer, generally two months for an individual house and three months for other types of buildings. This more rigorous procedure allows the administration to thoroughly verify the project's compliance with urban planning rules and local technical constraints.
What steps to follow to obtain authorization to build a swimming pool?
To obtain the necessary authorizations for building your swimming pool, you must follow a precise process. Here are the essential steps:
- Consult your commune's Local Urban Planning Plan (PLU) to find out the specific rules
- Prepare a complete file with plans, photographs, and technical notices
- Submit your authorization request to the town hall (in several copies)
- Wait for the processing period before starting work
The application file must contain several important elements such as the Cerfa form adapted to your situation, a site plan of the land, a mass plan indicating the location of the pool, a cross-section plan of the land and the construction, as well as photographs allowing the land to be situated in the near and distant environment. Depending on the case, other documents may be required, particularly in protected areas. At PoolPlanet, we recommend consulting a professional to help you prepare this file to avoid any rejection of your application.
What are the risks in case of non-declaration or non-compliance with formalities?
Building a swimming pool without complying with administrative obligations can lead to serious consequences. Penalties can be financial and legal, with a fine potentially reaching 6,000 euros per square meter built illegally. Beyond the fine, you also risk having to pay increased development and property taxes, or, in the most serious cases, being ordered to demolish your pool. Controls can be carried out by the town hall at any time, and in the event of a violation, a report will be drawn up.
Regularization after the fact is possible but remains complicated and costly. It involves submitting an authorization request for an already completed construction, with the risk that it may be refused if it does not comply with the urban planning rules in force. Furthermore, you will lose certain benefits such as manufacturer warranties or the ability to negotiate with your insurance in the event of a claim. To avoid these inconveniences, it is strongly recommended to comply with legal obligations from the very beginning of your project.
Conclusion
Complying with administrative formalities for building a swimming pool is essential to avoid legal and financial problems. Authorizations for building a swimming pool vary depending on the size and type of pool: no formalities for pools under 10 m², a prior declaration for those between 10 and 100 m², and a building permit for larger ones or those with a high enclosure. Compliance with local urban planning rules is also crucial, as they may impose additional constraints, particularly in protected areas.
To ensure your project's compliance, do not hesitate to consult your commune's Local Urban Planning Plan and contact local urban planning services. Good preparation of your file and adherence to procedures will allow you to serenely enjoy your pool for years to come. Investing time in these administrative steps is a small price to pay for the peace of mind that comes with a perfectly legal installation.
