Can I mow the lawn on Sunday?
It depends on your municipality — no federal law bans mowing on Sunday. Noisy garden tools fall under the municipal police regulation and the general rules on noise, which vary from town to town. A common pattern: noisy tools are allowed on weekdays within set hours (often around 8am to 8pm), limited on Saturdays, and often forbidden on Sundays and public holidays. Some municipalities allow it, others ban it entirely — check your local regulation. In Wallonia, since a decree of 9 April 2026 a regional rule targets robot mowers: banned between 6pm and 9am (to protect hedgehogs and nocturnal wildlife). In any case, don't cause excessive nuisance to neighbours (art. 3.101 of the Civil Code). In practice the local officer first aims for a conversation before a GAS fine follows.
📋 The rules
- No federal law: mowing on Sunday depends on the municipal police regulation
- Many municipalities: noisy tools only on weekdays (often ~8am–8pm), limited on Saturdays, not on Sundays and holidays
- Wallonia (since 9 April 2026): robot mowers banned between 6pm and 9am — regional rule
- No excessive noise nuisance to neighbours (art. 3.101 of the Civil Code)
- At night the ban on night noise also applies (art. 561 old Criminal Code)
- Always check your municipality: one allows Sunday, another forbids it
🔓 Exceptions
- A quiet, electric or hand mower often falls outside the ban on 'noisy' tools — check the wording
- The Walloon robot-mower rule does not cover sports fields or safety situations (e.g. airports)
⚠️ Penalties & fines
Breaching the police regulation risks a GAS fine: maximum €500 for adults and €175 for minors (€350 in municipalities that haven't updated their regulation); for neighbourhood noise the fines usually fall between €75 and €350. The Walloon robot-mower rule is a third-category environmental offence, with a fine from €50. In practice a warning or mediation often comes first.
