Planning Practice FAQ's

Except in specific cases, before any building can be placed on a piece of land it must have a 'Certificat d'Urbanisme'. This equates roughly to what is called 'Outline Planning Permission' in the UK. An application for this can be made at any time, for any land. However, if the land is not within specified building development areas, the chances of success may be limited. If you are buying an existing property, where appropriate the Notaire will ensure it has a CU. If not, then the property cannot automatically be used as a habitation. For example, if you buy land with a barn, you may need to apply for a CU to convert the barn to living space.

We use this term in a general sense because there are a number of different individual applications contained within its format. Assuming you have a CU on land or a property, if you wish to change its use or construct a building, an extension, or perhaps demolish an existing building, install a swimming pool, etc., then you will need to apply for a 'Permis de Construire' of one type or another.

​

The granting of this permit will allow you, in principle, to proceed with your project - subject to certain conditions that will be expressed at the time you receive the approval documents. In most cases it takes between two and three months from the date of submission of the application until an answer is given. In certain cases it can take up to 6 months. The authorities have specific time limits in which to request additional information or documents, or to refuse permission. If they do not do so within the relevant period, you will normally have automatic permission to proceed. For example, if you want to convert an attic space into living accommodation, the authorities usually have 2 months in which to request other documents, or to refuse the application. If they do not, your permission is granted by default, although there are certain procedures to follow before you can begin work. If, however, they request information half way through this period, then they have a further two months after you have supplied them with the requested items before automatic permission applies.

Where a project involves only minor changes - like a new door opening or the fitting of Velux windows - then the application is usually dealt with by a 'Declaration Préalable' (beware though, because if your intention is to fit Velux windows in order to convert an attic into bedrooms, then you may need a 'Permis de construire'). With this type of application, the time limit before automatic approval applies is usually only one month, but the same applies here as regards additional information requested by the authorities - the clock only counts down once all the documentation is received.

In France, a registered French architect is required to submit any planning application, except in certain specific, clearly defined cases. For simplicity, we will only mention the most relevant one here. If the net floor area (as defined by specific conditions) of your existing property, or the total area after any extension, is below 150 sq m, then an architect is not required. This area includes basements & attics that can be converted (again as defined by specific conditions) for use as accommodation, even if you do not intend to use them in this way. We can give specific advice on this at the time of our initial discussion.

Unlike in other countries there are no fees paid to the state on submission of the planning application.  If the application is successful then a planning tax (taxe d'aménagement) is levied, based on the surface area created.

In most cases yes - a shed, greenhouse, polytunnel, tiny home or shepherds hut will require some kind of planning permission.  Any space created that is permanently erected and over 5m2 needs permission.  In some instances this will be a DP and in others a PCMI. If the tiny house is for habitation then it would also need drainage and an electrical connection.

​

If a shepherds hut is mobile and you only want to have it in place for the summer months then permission from the Mairie is still often required.

In certain locations there is no possibility of permission even for temporary structures like these so its worth checking before purchase.
