In most cases, the pergola is therefore not taxable.

The pergola becomes taxable if these 3 criteria are met:

• Its area exceeds 5m²

• If it is enclosed on at least 3 sides

• If it is permanently covered (zip-up awnings are not considered permanent enclosures)

These criteria make the pergola similar to a sunroom. In such cases, the pergola may be included in the calculation of the development tax. Regarding property tax, a pergola does not increase this tax. But be careful: it is your patio that will affect the calculation of your property tax.

If your carport’s area exceeds 20m², you’ll need to apply for one. This is particularly the case if you plan to park a motorhome or two vehicles side by side. The processing time for a building permit is generally 2 months.
