Pruning a tree with permit requirements: legal rules and procedures

Why does tree pruning need a permit?

Many municipalities protect large trees with regulations because trees:

• Provide urban greenery (beauty, dust filter, oxygen)
• Handle water buffering (rainwater capture)
• Improve air quality (particle filter)
• Add value to neighbourhoods

That is why you cannot just prune randomly. Depending on your municipality, you may need a permit or notification.

Who decides if a tree is protected?

In the Netherlands and Belgium, rules differ PER MUNICIPALITY. This is crucial:

Dutch municipalities:

• The municipality decides which trees are protected
• Usually trees LARGER than a certain trunk diameter (e.g. 50 cm)
• Some municipalities have a "tree protection ordinance"
• Young trees (under 10 years) are usually unprotected

Belgian municipalities:

• Rules vary per region (Flanders, Wallonia, Brussels)
• Flanders: many municipalities have protection rules
• Wallonia: also rules, but differ per municipality
• Brussels: very strict tree rules

Your FIRST STEP: Check your municipality website. Each has information online.

How do you know if your tree is protected?

Checklist:

1. Google: "[your municipality] tree protection" or "[your municipality] tree ordinance"
2. Call your municipality (Green/Sustainability/Planning department)
3. Investigate your front yard: is there anything posted?
4. Ask directly: "Is tree X on my property protected?"

Many municipalities have online maps of protected trees.

General indicators (but always check first):

• Trees larger than 50-80 cm trunk diameter: probably protected
• Trees in groups (3 or more together): probably protected
• Trees on public land (in front of your house): probably protected
• Young trees (under 10 years, thin): probably NOT protected

What is the difference between notification and permit?

Notification (easier):

• You notify the municipality of the pruning
• "I want to prune my tree on [date]"
• Municipality checks: is it necessary/safe?
• Usually: red light (no) or green light (yes)
• Faster process (1-4 weeks)
• You pay nothing or little (e.g. 25-50 euros)

Permit (stricter):

• You ask PERMISSION to prune
• You file an application with photos and description
• Municipality takes more time (2-8 weeks)
• Risk of rejection is higher
• Costs higher (50-200 euros+)

Felling permit (much stricter):

• You want to REMOVE the tree entirely
• This MUST usually go through full permitting
• Municipality may refuse
• Many municipalities allow felling only if tree is sick/dead
• Very long process

Step-by-step action plan

Step 1: Check your municipality online

Go to your municipality website. Search for:

• "Tree protection"
• "Green management"
• "Tree ordinance"
• "Green rules"

Download PDFs or read directly. This is MOST RELIABLE.

Step 2: Determine if your tree is protected

Measure your tree:

• Circumference at breast height (roughly 1.30 metres up the trunk)
• This determines if it is protected (usually: larger than 50-80 cm = protected)

Count your trees:

• Are there several together? (protection group?)
• What is their age?

Step 3: Establish what you want to do

You want to:

• Remove dead branches (deadwooding): usually NO permit needed (safety first)
• Light pruning: notification may suffice
• Heavy pruning (>20% removed): permit needed
• Remove tree: almost always permit needed

Step 4: File notification/permit

Call or email your municipality:

• "I have a question about pruning a tree on my property"
• Describe: "It is an apple/oak/beech tree, diameter about X cm, I want to..."
• Send photos
• Ask: "Does this need notification/permit?"

The municipality will advise.

Step 5: Wait for approval

Notification: 1-4 weeks Permit: 2-8 weeks (sometimes longer)

Wait until you have WRITTEN approval. Do not start if municipality responds negatively!

Step 6: Execute per requirements

The approval may have conditions:

• "Only dead branches may be removed"
• "Do not remove more than 20%"
• "Complete by 31 March"
• "You must hire a professional"

Follow these! Otherwise fines follow.

Frequently asked questions

What happens if I prune without a permit?

This can be very expensive:

• Fine: 500-5000 euros (varies per municipality)
• Remediation: you must restore the tree (expensive!)
• Lawsuits: neighbour disputes can escalate
• Reputation: gardening circles are small

So: always ask first.

I just want to pinch off a few shoots. Do I need a permit?

Young growth pinching (young greenery) or very light maintenance:

• Usually NOT permit-required
• But: watch large branches (bigger than your thumb)
• If in doubt: call municipality

My tree is sick/dead. Can I remove it?

Probably YES, but:

• You must PROVE it (photos of fungus/death)
• Municipality may send a tree expert
• You pay for that examination (100-300 euros)
• If they agree: then felling permit

So: gather evidence first.

My neighbour prunes without a permit. Can I complain?

Yes, you can report it:

• "I see tree X is being pruned without permit"
• Municipality investigates
• Can result in fine for neighbour

Careful: this can worsen neighbour disputes. Better speak to neighbour first.

Can I hire a professional tree technician?

YES, very good idea. A professional:

• Helps with permit application
• Performs work professionally
• Has insurance
• Complies with all rules

Costs: 50-300 euros for consultation + work.

Specific rules per region (guidance)

Netherlands:

• Many municipalities: trees >60cm trunk diameter protected
• Typical: notification suffices for light pruning
• Deadwooding (dead branches): usually no permit needed
• Felling permit: very difficult (usually refused unless dead)

Belgium - Flanders:

• Many municipalities: trees with circumference >80cm protected
• Rules vary widely per municipality
• Some places: very strict (Antwerp, Brussels)
• Others: more lenient

Belgium - Brussels:

• Very strict rules
• Almost everything needs permit
• Municipality can quickly refuse

Belgium - Wallonia:

• Less stringent than Flanders
• Still varies per municipality

Prevention is better than cure

• Plant young trees correctly (train good form early)
• Maintain regularly (avoid emergency pruning)
• Check regularly with municipality (avoid surprises)
• Document everything (photos, emails)
