Tree and Hedge Planting Distances: French Civil Code Rules

Do you dream of a lush green garden, a protective hedge to preserve your privacy, or a majestic tree to shade your summer afternoons? While the prospect of adding greenery to your property is appealing, it is also governed by strict legal rules in France. To prevent your thuja hedge or century-old oak from becoming the starting point of an endless neighborhood dispute, it is essential to master the distance rules imposed by law. Whether you are an owner, a tenant, or a foreign resident recently settled in France, here is the complete guide to planting legally and preserving peace with your neighbors.

The Legal Framework: What the French Civil Code Says

French law strictly regulates planting to guarantee that everyone's property, light, and safety are respected. The basic rules are defined by the Code civil (French Civil Code), but they can vary depending on local specificities.

The General Rule of the Civil Code (Article 671)

In the absence of local rules (established local customs, co-ownership regulations, or local urban plans), *Article 671 of the Code civil*** applies by default throughout the French territory. This text establishes a fundamental distinction based on the height of the plant:

• For plants with a height exceeding 2 meters: The minimum distance to be respected between the trunk of the tree and the boundary line separating the two properties is 2 meters.
• For plants with a height of 2 meters or less: The minimum distance to be respected from the property boundary is 0.50 meters (i.e., 50 centimeters).

How to Correctly Measure Distances and Heights

To avoid any dispute, the calculation method must be rigorous:

• The distance is measured from the center of the tree or shrub trunk (at ground level) to the boundary line separating the two properties (the limite séparative).
• The height is measured from the ground level where the tree is planted to the highest point of the plant (the crown).

The Exception of Local Customs and Urban Planning Regulations

Article 671 of the Code civil begins with these words: "It is only permitted to have trees, shrubs, and bushes near the boundary of the neighboring property at the distance prescribed by the specific regulations currently in force, or by constant and recognized customs..."

This means that local rules take precedence over the Civil Code. Before planting, you must imperatively check:

• *The Plan Local d'Urbanisme (PLU) (Local Urban Plan) or the municipal map at your local mairie* (town hall). Some municipalities impose more restrictive distances to protect the landscape or prevent fire risks.
• *Local customs (usages locaux): For example, in Paris and its immediate surrounding departments (Seine-Saint-Denis, Hauts-de-Seine, Val-de-Marne), an established custom allows planting right up to the extreme boundary of properties, provided it does not cause an inconvénient anormal de voisinage* (abnormal neighborhood disturbance).
• *The subdivision specifications (cahier des charges du lotissement) or the co-ownership regulations (règlement de copropriété): These private documents can impose very strict restrictions (maximum hedge height limited to 1.20 meters or 1.50 meters*, prohibition of certain tree species, etc.).

Overhanging Branches and Roots: The Neighbor's Rights

What should you do if the branches of your neighbor's cherry tree overhang your lawn, or if the roots of their bamboo lift the tiles of your terrace? The Code civil grants very different rights depending on whether you are dealing with branches or roots.

Cutting Branches: The Prohibition of Taking the Law into Your Own Hands

According to *Article 673 of the Code civil, if branches of trees, shrubs, or bushes of a neighbor overhang your property, you cannot* cut them yourself. You must obligatorily demand that your neighbor cut them.

This right is imprescriptible (it does not expire): even if the branches have overhung for more than 30 years, you retain the right to demand their pruning. If the neighbor refuses, you must take legal action to compel them.

Cutting Roots, Brambles, and Twigs: A Direct Right

Conversely, the same *Article 673 of the Code civil*** specifies that if roots, brambles, or twigs encroach onto your land, you have the right to cut them yourself, at the boundary line, without needing your neighbor's permission or a court decision.

Concrete and Numerical Examples

To better understand the application of these rules, let us analyze two everyday situations.

Example 1: The Dispute Over Jean and Marc's Thuja Hedge

Jean and Marc are neighbors in a municipality with no specific local rules. Jean planted a thuja hedge 60 centimeters from Marc's fence. Over the years, Jean let his hedge grow, and it now reaches a height of 2.50 meters.

• The Legal Analysis: Since the hedge is located less than 2 meters from the property boundary (it is at 60 cm), its maximum authorized height is 2 meters.
• The Solution: Marc is entitled to demand that Jean top his hedge to bring it down to a maximum height of 2 meters. If Jean refuses, Marc can initiate legal proceedings. If the case goes to court, the judge can order the topping under a financial penalty (astreinte), for example, 50 € per day of delay.

Example 2: Elena and Arthur's Century-Old Oak

Elena owns a magnificent century-old oak tree located 1.80 meters from Arthur's property boundary. Its branches overhang significantly into Arthur's garden, depriving his terrace of sunlight.

• The Legal Analysis: The oak tree significantly exceeds 2 meters in height and is planted less than 2 meters from the boundary line. However, this oak tree was planted more than 30 years ago.
• The Solution: Elena can invoke the prescription trentenaire (thirty-year prescription) to keep the tree at this distance. On the other hand, Arthur retains the imprescriptible right (under Article 673) to demand that Elena prune the branches that overhang his property, as prescription does not apply to overhanging branches.

Practical Steps: How to Resolve a Conflict Step-by-Step

If you notice that a neighbor's plant does not respect legal distances or creates a nuisance, do not give in to anger. Follow this rigorous 5-step procedure:

1. Amicable Dialogue: Go see your neighbor or write them a polite note. Often, property owners are not aware of the height of their trees or the inconvenience caused. Propose finding a compromise.

2. Verification of Local Rules: Go to the mairie to consult the PLU or local customs to ensure your request is legally grounded.

3. Formal Notice by Registered Letter: If dialogue fails, send a lettre recommandée avec accusé de réception (LRAR - registered letter with acknowledgment of receipt) to your neighbor. Recall the facts, cite Article 671 or *673 of the Code civil**, and formally demand (mise en demeure*) that they cut or prune their plants within a reasonable timeframe (generally 15 to 30 days).

4. Recourse to a Mediator or Justice Conciliator: Since the recent judicial reforms in France, for this type of neighborhood dispute, resorting to an amicable resolution method is mandatory before you can petition a court. This process is entirely free of charge. You can find a conciliateur de justice (justice conciliator) near you on the official website of the Ministry of Justice.

5. Filing a Case with the Judicial Court: If conciliation fails, you can bring the matter before the Tribunal judiciaire (local court of the property's location). The judge can order the pruning or removal of the tree, and potentially order the neighbor to pay you damages for trouble anormal de voisinage (abnormal neighborhood disturbance).

Mistakes to Avoid

• Cutting the neighbor's branches yourself: This is the most common mistake. Even if the branches damage your roof or block your view, you commit a trespass/unlawful act (voie de fait) by cutting them without agreement. The neighbor could turn against you and claim damages for damage to their property.
• Ignoring co-ownership or subdivision rules: Thinking that only the Civil Code applies is a classic mistake. Private regulations (cahier des charges) are often much stricter and remain valid even when faced with the Civil Code.
• Waiting too long to act against planting distance: If a tree is planted too close to the property boundary (for example, at 40 cm instead of 50 cm), you have 30 years to act. Past this period, the thirty-year prescription applies, and you can no longer demand its removal or relocation (unless it causes an abnormal neighborhood disturbance or its branches overhang).
• Neglecting maintenance as a tenant: If you rent a house with a garden, be aware that routine maintenance of the exterior (trimming hedges, pruning shrubs) is a rental charge (charge locative) that legally falls on you. The landlord can withhold restoration costs from your caution (security deposit) if the garden is left abandoned.

FAQ: Frequently Asked Questions on Planting Distances

Can my neighbor plant bamboo along our fence?

Yes, but under certain conditions. Bamboo plants have running roots (rhizomes) that spread rapidly underground and can cause major damage to the neighbor's property. If they are planted less than 2 meters from the boundary, they must not exceed 2 meters in height. Furthermore, if the roots invade your land, you have the right to cut them. The neighbor can be ordered to install a root barrier at their own expense if an abnormal neighborhood disturbance is established.

Who must pay the pruning costs for shared (party) trees?

A tree or hedge is said to be mitoyen (shared/party) if it is planted astride the boundary line of the two properties. According to *Article 667 of the Code civil***, a shared hedge must be maintained at shared expense. Both neighbors must therefore share the costs of maintenance, trimming, or felling equally (50/50).

What is the "thirty-year prescription" for a tree?

The prescription trentenaire is a legal mechanism by which an owner acquires the right to keep a tree that does not respect legal distances. If the tree was planted too close to the property boundary but has exceeded the height of 2 meters for more than 30 years without the neighbor objecting, the neighbor can no longer demand that it be topped or removed. Note: the 30-year period starts running on the day the tree exceeded the fateful height of 2 meters, and not on the day it was planted.

Does the presence of a fence or a shared wall change the rules?

Yes. If a non-shared wall (belonging exclusively to you) separates the properties, you can train espalier trees (fruit trees trained to grow flat against a wall) against it without respecting a minimum distance, provided they do not exceed the crest of the wall. If the wall is shared (mitoyen), you must obtain the neighbor's agreement to train plants against it.

Summary

• Less than 2 meters in height: minimum distance of 0.50 meters from the property boundary.
• More than 2 meters in height: minimum distance of 2 meters from the property boundary.
• Priority to local rules: always check the PLU at the town hall and your subdivision or co-ownership regulations before buying or planting.
• Neighbor's branches: absolute prohibition to cut them yourself; you must demand that the neighbor do it (an imprescriptible right).
• Neighbor's roots: you have the right to cut them yourself if they encroach on your land.
• Conflict resolution: always prioritize dialogue, then a written formal notice, and finally mandatory conciliation before any action before the Tribunal judiciaire.
