Do You Need a Permit for an Inground Trampoline Installation? in Netherlands
Sometimes. Digging a large pit for an inground trampoline can trigger grading or excavation permits, especially when the hole affects drainage patterns or sits near utility easements. Many jurisdictions treat trampolines as recreational equipment requiring safety fencing, and some HOAs ban them outright. Always check setback and drainage rules before breaking ground.

Country-specific detail
In the Netherlands, inground trampolines are typically vergunningsvrij (permit-free) under the Omgevingswet as they do not constitute a bouwwerk (structure). The excavation must not affect the waterhuishouding (water management) of the area — if the pit impacts grondwater (groundwater) levels or is in a waterwingebied (water extraction zone), the waterschap (water authority) may require a watervergunning. In areas with a bestemmingsplan restriction or on gemeentelijk monument terrain, the gemeente may impose additional conditions. Standard installation in a regular tuin (garden) requires no permit.
