For many homeowners and expats in the Netherlands, it is unclear when a building permit is required for renovations. While the rules may seem straightforward on paper, in practice there are many details and exceptions in the various Dutch renovation laws and local regulations. This guide explains clearly when you need to apply for a permit, when you can build permit-free, and how to manage the paperwork smartly in 2026.

When Do You Need a Building Permit?

A permit is required if you significantly alter the structure, appearance, or fire safety of your home. Examples include:

  • Extending or adding an annex to your home

  • Installing a dormer on the front side

  • Moving or removing load-bearing walls

  • Fully changing the facade

Municipalities are now stricter regarding safety and energy performance. Building without a permit can result in a stop-work order, fines, or even being required to undo the work.

When Can You Build Without a Permit?

Not every renovation requires a permit. Smaller projects often fall under permit-free building, as long as you stay within legal limits. Examples include:

  • Installing a new kitchen or bathroom in the same location

  • Replacing window frames in a similar style

  • Adding a rear dormer within standard dimensions

  • Building a garden shed or storage unit within maximum height and area

Note: “permit-free” does not mean rule-free. Even without a permit, you must comply with the Dutch Building Decree, fire safety standards, and local regulations. Extra restrictions apply for monuments or protected cityscapes.

How to Apply for a Building Permit

Applications are submitted via the digital Omgevingsloket. You provide information about your home, upload drawings, and describe the planned renovation. Larger projects often require structural calculations and technical details.

Municipalities typically take 6 to 8 weeks to make a decision. For expats, this process can be challenging due to:

  • Everything being in Dutch

  • Each municipality having its own interpretations of renovation laws

  • Complex technical drawings and documentation

For this reason, many homeowners prefer to work with a professional who has experience with permit applications.
