Regulation
Solar carports in France: prior declaration or building permit?
Since late 2024, French carports are no longer treated as ordinary buildings. The regime depends mainly on the project’s capacity and location.
The rule since 1 December 2024
For applications filed from 1 December 2024, planning rules for solar carports were aligned with those for ground-mounted plants. Outside heritage-protected areas, a prior declaration applies up to 3 MWp and a building permit above it. The threshold used to be 1 MWp.
| Situation | Consent |
|---|---|
| Outside protected areas, up to 3 MWp | Prior declaration |
| Outside protected areas, above 3 MWp | Building permit |
| Protected area (near monuments, listed sites…) | Stricter regime, heritage architect’s opinion |
What to check locally
- The local plan (PLU): height, setbacks, appearance, parking rules.
- Heritage and landscape protection: it changes the procedure and the architectural bar.
- Coastal law: in coastal municipalities, recent case law treats a carport as an extension of urban development, which must adjoin an existing settlement.
- Easements: power lines, airports, networks.
Building a strong application
Location plan, site plan, sections, landscape integration and a written notice: for a carport, integration often decides the outcome. A slender structure with few supports and a continuous roofline is easier to defend before planning officers or heritage architects than a forest of columns. Architect-grade visuals and dimensioned sections save time.
At SUUN
We provide developers and architects with the graphic and technical material needed for the application: typical sections, clearances, layout principles and integration visuals. Request documentation.
Frequently asked questions
How long does review take?
Typically one month for a prior declaration and two to three months for a building permit, longer in protected areas.
Does the APER obligation replace planning consent?
No. The duty to add solar does not replace planning consent: the project must still be declared or permitted.
