Do You Need a Permit?

It depends:

| Situation | Permit required? | |---|---| | Attached garage — change of use to living/office space | Omgevingsvergunning (change of use) required | | Detached garage — internal works only | Often permit-free — check bestemmingsplan | | Adding windows or doors to the façade | Permit required | | Removing load-bearing walls | Permit + structural drawings required |

Always verify on omgevingsloket.nl before starting.

Do You Need an Architect?

  • Simple conversion (storage/office): architect not required
  • Change of use to dwelling or studio: architect recommended for the permit application
  • Structural changes: structural engineer and drawings required by law
  • Listed building or apartment complex: architect required in all cases

Building Regulations to Check

  • Minimum ceiling height: 2.4 m required for habitable rooms (check before committing)
  • Daylighting: at least 10% of floor area in window area for habitable rooms
  • Ventilation: mechanical ventilation or natural ventilation meeting Bouwbesluit 2012 requirements
  • Energy performance: if renting, the space must meet minimum insulation values

Tips to Reduce Costs

  • Keep the garage door opening — fit a window-and-wall infill rather than rebuilding the whole facade
  • Choose drylining (plasterboard) over plastering — typically 20–30% cheaper
  • Collect at least 3 quotes — price differences of up to 50% are common
  • Combine the conversion with other planned works (solar panels, heating upgrades) to reduce labour mobilisation costs

Conclusion

Converting a garage to living space in the Netherlands in 2026 costs € 15,000–€ 45,000 for a standard attached garage. A change-of-use permit is almost always required. Check ceiling height and daylighting requirements before you commit.
