Renovating in Nice means complying with several rules: planning permission or prior declaration, the local urban plan (PLU), co-ownership regulations and technical standards (electrical, thermal, accessibility). Here is a clear 2026 overview so your project stays fully compliant.
Planning rules
- Prior declaration (déclaration préalable) for minor exterior changes (façade, windows, small extensions).
- Building permit (permis de construire) for larger extensions or significant changes.
- PLU — the local urban plan sets what is allowed in your area; protected and heritage zones in Nice have stricter rules.
Co-ownership (copropriété)
Works affecting common areas, the façade or load-bearing walls require the co-owners’ assembly approval. Internal, non-structural works are usually free of this constraint.
Technical standards
- Electrical — installations must meet the NF C 15-100 standard.
- Thermal — energy rules (RE2020 logic) apply to extensions and new builds.
- Accessibility & safety — specific rules for shared and commercial spaces.
