Article 663 of the French Civil Code (C.civ.) provides that in towns and suburbs, each owner can require their neighbour to contribute to the construction and repairs of the separating fence. In practice, if you build a fence on the property line, your neighbour may be required to pay 50% of the cost. In Cannes, this obligation applies in the built-up area (UA zone of the CASA PLU).

## 2. Allowed height and materials in UA zone

The Local Urban Plan (PLU) of the Sophia Antipolis Agglomeration Community (CASA) sets precise rules for fences in UA zone: maximum height of 2 metres, materials in harmony with the surrounding built environment (stone, tinted render, simple bar grille). Unfinished concrete block fences are prohibited. A RAL colour of sand or cut stone is generally required.

## 3. Prior declaration of works

Any creation or modification of a fence over 2 metres in height requires a prior declaration at the town hall (Article R421-11 of the Urban Planning Code). In Cannes, the reviewing service checks compliance with the PLU and the opinion of the Architect of Buildings of France (ABF) if the project is within the safeguarded sector (e.g., Suquet district).

## Frequently asked questions

### Who pays for a fence on the property line in UA zone?

In a UA (urban, town-centre) zone, the cost of a fence on the property line is typically shared equally between adjacent property owners, unless there is a prior agreement or local ordinance stating otherwise. If one owner builds the fence without the other's consent, they may bear the full cost, but they can seek reimbursement if the fence benefits both properties.

### Can I build a fence directly on the property line in UA zone?

Yes, you can build a fence directly on the property line in a UA zone, but you must comply with local zoning codes, which often require a permit and may have height restrictions. It's advisable to discuss with your neighbour and consider a shared fence agreement to avoid disputes.

### What are the fence height rules in UA zone?

In UA zones, fence height rules vary by jurisdiction, but common limits are 6 feet for side and rear yards, and 3-4 feet for front yards. Always check your local zoning ordinance, as some areas may allow taller fences for agricultural purposes if they don't obstruct sight lines.
