Are you thinking ofinstall a garden shed make the most of your outdoor space? Before you get started, it’s important to be aware of the applicable administrative and tax regulations. In France, certain requirements apply for structures 3 square meters or larger.
Here's everything you need to know to carry out your project with complete peace of mind.
1. What steps do I need to take at city hall?
Regulations depend mainly on the size of your garden shed.
✔️ Between 3 and 20 square meters
You must file a preliminary construction notice (DP) with the town hall.
👉 This process allows your municipality to verify that your project complies with local zoning regulations (PLU).
✔️ Over 20 m²
A building permit is required.
👉 The application is more comprehensive, and the processing time is longer (about 2 months).
📌 Good to know
- If your property is located in a protected area (such as a historic monument or a designated site), the rules may be stricter.
- The Local Urban Planning Plan (PLU) may impose restrictions (regarding materials, height, location, etc.).
2. What taxes apply to a garden shed?
Installing a garden shed larger than 5 square meters may result in a development tax.
How is it calculated?
It depends on three factors:
- Taxable area (interior area of the shelter)
- A national flat rate (revised annually)
- The rate set by your municipality and county
👉 As a rough estimate, the tax can amount to several hundred euros, depending on the size and location.
⚠️ Please note
- It is payable only once, after the planning permit has been granted.
- This applies to enclosed, covered structures larger than 5 m² with a ceiling height greater than 1.80 m.
3. Are there any additional taxes?
Yes, in some cases 👇
Property tax
A garden shed can be considered a permanent structure.
👉 This can therefore lead to an increase in property taxes, especially if it is attached to the ground.
No separate housing tax
Good news: there is no specific property tax for garden sheds.
4. Guidelines to Follow Before Installing Your Shed
Before making a purchase, be sure to check:
- Distance guidelines for neighbors
- The maximum permitted area
- The regulatory height
- Aesthetic considerations (color, materials, etc.)
👉 All this information is available at city hall or in your local land-use plan.
5. In summary

|---|---|---|
| 3 to 5 square meters | None or DP, depending on the municipality | No tax |
