Swimming pools without planning permission: when is it possible?

It is entirely possibleto build a swimming poolwithout filing apermit application, provided that certain criteria related to the surface area, installation duration, and land location are met.

Small pools (less than 10 m²)

The unlicensed pools are those with a surface area of 10 m² or less. For these mini-poolsIn most cases, no formalities are required. These pools are generally suited to small plots of land or to projects on a moderate budget.

However, be aware: even a pool of less than 10 m² may require authorization if it is located in aprotected area, near a historic monument or within aclassified site. In this case, it is imperative to inquire with the town hall before starting the work.

Temporary above-ground pools

The undeclared pools also apply to certain dismountable above-ground structures, notably inflatable or tubular pools, provided they are not fixed to the ground and are installed for a maximum period of three months (15 days in protected areas).

These models, easy to install, are exempt from formalities, provided that local planning rules are respected.Here again, it is best to inquire withyour municipality to avoid any disputes.

Prior declaration of work: a frequent formality

Between 10 m² and 100 m², thesize of the poolfalls within an intermediate regulatory zone. In this case, the law requires aprior declaration of worksto be filed with the town hall. This procedure allows the administration to verify that the project complies with thelocal urban planning code(in particular the rules of the PLU – Local Urban Plan).

Theprior declaration of worksis a "lightened" file, to be submitted at least one month before the start of the construction site. It also concernsshell poolsas standard, whose dimensions generally exceed 10 m². It may also be required for a pool of less than 10 m² located in a classified area.

When is planning permission required?

Abuilding permitis required as soon as thepool sizeexceeds 100 m². It is also required if you plan to install apool enclosureover 1.80 m high, regardless of the pool dimensions.

This type of application is more complex and requires longer processing times (generally two months). These are often large-scale projects, particularly in the case of in-ground pool with additional equipment, or covered facilities for prolonged use.

Certain specific configurations, such as an indoor swimming pool requiring structural modifications, may also necessitate abuilding permit, even if the surface area remains modest. Again, you should inquire with your local town hall before making any decisions.

A few special rules to bear in mind

In addition to the traditional approaches, several factors can influence the applicable regulations:

The Local Urban Development Plan (PLU)

Each municipality defines its own rules via the PLU. This may imposeminimum distances from property lines, prohibit certain aesthetic finishes, or restrict the use of specific materials. It may also make authorization mandatory even forsmall swimming poolsor above-ground ones.

These factors must be taken into account before any commitment is made.

Protected areas and classified sites

In a protected sector,in a protected zoneor near aclassified site,the opinion of the Architecte des Bâtiments de France is often required. A simpleswimming pool without a building permitcan then become a project subject to strict authorization. These areas are particularly monitored to preserve heritage or the environment.

Declarable equipment: the example of the heat pump

The addition of fixed equipment, such as aheat pump, can have regulatory implications. Even if it is not strictly speaking a building, its integration into the landscape or its potential noise pollution may require aprior declaration of works, depending on the local urban plan in force.

Summary of project-related obligations

When it comes to building a swimming pool without a permitcaution is essential. The rules vary according to a number of parameters: type of pool, pool sizeinstallation time, location, presence of a shelter or equipment such as a heat pump.

The right approach is to inquire with your local town hall, study local constraints, and anticipateadministrative procedureswell before the start of the work.
